INTRODUCTION
Service Information S280-30-7 provides the maintenance
instructions for Type VW, VWV27 and VWV38 three-phase,
hydraulically controlled, vacuum reclosers. Included is a general description of the recloser and its operation, instructions for
periodic inspection and routine maintenance, testing procedures, and instructions for shop repairs. A service parts list,
keyed to exploded-view drawings of the recloser is included at
the back of the manual.
DESCRIPTION AND OPERATION
General
The Type VW, VWV27 and VWV38 reclosers are self-controlled
devices that sense and interrupt distribution system fault currents. They automatically reclose to restore service if the fault is
temporary and then reset for another programmed sequence of
operations. If the fault is permanent the recloser locks open
after one, two, three or four operations, depending upon its
operating settings. All three phases open, close, and lock out
simultaneously.
Opening sequences of these reclosers can be all fast, all
delayed, or any combination of fast followed by delayed operations; up to the maximum of four operations. On coordinated
systems, fast operations clear temporary faults before branchline fuses can be damaged. Delayed openings allow time for
fuses or other downline protective devices to clear so that permanent faults can be confined to smaller sections of line
Closing energy, as well as energy to charge the opening
springs, is supplied by a high-voltage closing solenoid which is
momentariIy connected phase-to-phase through a high-voltage
contactor.
Figure 2.
Untanked Type VW vacuum recloser.
A “trip-free” yellow operating handle, located under the sleet
hood, will manually lock open the recloser. It cannot manually
close the recloser, but must be in the CLOSED position for the
closing solenoid contactor to operate. A red contact position
indicator, linked to the recloser mechanism but independent of
the yellow operating handle, is also located under the sleet
hood.
The location of the major components of a VW recloser are
shown in Figure 2. They are similar for the VWV27 and VWV38
reclosers. Being aware of the location of these components and
their operation will provide a quicker and clearer understanding
of the recloser maintenance and repair procedures that follow.
Manual Operating Handle
When the recloser operates to lockout, the (yellow) manual
operation handle drops down (“trips-free”) from under the sleet
hood, to give a visual indication of recloser lockout. The handle
must be reset manually before the recloser can be closed. Lifting the handle up mechanically closes the closing solenoid contactor, and if power is available to the closing coil circuit, the
closing solenoid will energize, resetting the recloser.
A closed recloser can be manually opened and locked out by
pulling down the yellow handle.
Non-Reclosing Lever
The non-reclosing lever provides the capability for locking out
the recloser on the first trip operation regardless of the programmed number of operations to lockout.
Contact Position Indicator
The red arrow-like contact position indicator flag is coupled to
the recloser mechanism to show the position of the main contacts. When the flag is down, the vacuum interrupter contacts
are open; when the flag is up, the contacts are closed.

Types VW and VWV Maintenance Instructions
Vacuum Interrupters
Circuit opening and fault interruption is achieved within the three
sealed vacuum interrupters. The moving contact rod assemblies
are operated by the recloser mechanism to open and close the
vacuum interrupter contacts. Berylium copper garter springs are
used in the current exchange assemblies to provide a multi-point
low resistance current path between the stationary bushing leads
and the moving contact rod of the interrupters.
When the recloser mechanism is sequenced to the delayed
operation phase, the speed of plunger movement is restrained
by a time-delay unit. The restrained plunger movement provides a fixed time delay before the recloser mechanism trips.
Closing Solenoid
The moving contacts of the interrupters are closed by the closing
solenoid, which also extends the opening springs in the head
mechanism. This solenoid is energized for only a few cycles during each closing operation when it is momentarily connected
across phases B and C.
SERIES
TRIP
SOLENOID
Closing Solenoid Contactor
Mechanically operated by the head mechanism, the snap-action
contacts of the closing coil contactor complete the high-voltage
circuit to the closing solenoid for each closing operation.
Hydraulic Pump and Lockout Piston
The hydraulic pump counts the number of times the recloser trips.
With each trip the pump piston is pushed into the pump cylinder,
oil is forced through the lockout cylinder check valve into the lockout cylinder. This causes the lockout piston to be raised one step.
When the recloser resets the pump piston is pulled back to the
top of the pump cylinder and oil is drawn in through the intake
check valve.
If the recloser trips again the pump piston will actuate causing
the lockout piston to be pushed up another step. This cycle will
repeat until the recloser locks out. Once locked out the quick
reset rod is mechanically raised allowing the lockout piston to
quickly resettle. If the recloser does not lockout, the lockout piston will resettle gradually (at a rate of approximately 90 seconds
per accumulated operation at 25°C).

Time Delay Unit
Series Trip Solenoids
The series trip solenoids (Figure 3) are connected in series with
the vacuum interrupters, each carries full line current. When line
current exceeds the minimum trip rating of a coil, by approximately 200 percent, the plunger is drawn into the solenoid. Near
the end of the plunger stroke the recloser mechanism trips.
DELAY
ARM
When the mechanism is sequenced to a delayed operation the
latch assemblies of the trip solenoid plunger linkages are
engaged with the arms on the sealed time-delay units, Figure 4a
and 4b. Trip solenoid plunger movement is then restrained by the
time-delay unit, which provides a consistent delay action by forcing hydraulic fluid through a calibrated orifice within the unit.

MECHANISM OPERATION
The operating mechanism, mounted in the head, opens and
closes the vacuum interrupter contacts. Contact opening is initiated by a series trip solenoid which triggers the trip mechanism
to release the loaded opening springs. Contact closing is performed by the closing solenoid which also charges the opening
springs and resets the mechanism for the next trip operation.
The basic operation of the mechanism is shown in Figure 5.
With the interrupter contacts closed (a), the opening springs
are fully extended and the mechanism is in the reset state. When
excessive current levels are passing through the series trip coil
the solenoid plunger is actuated. The trip solenoid plunger operates the toggle latch, releasing the toggle. This action releases
the opening springs (b) which starts the contact bar assembly in
motion. The spring-biased reset lever rotates to snap the toggle
closed. This action of the reset lever also pulls the plunger out of
the closing solenoid. At this point the interrupter contacts are
fully open (c) and the mechanism is in the open state. When the
closing solenoid plunger reaches the top of its stroke it mechanically closes the closing coil contactor which energizes the closing solenoid. As the plunger is drawn down into the coil the reset
lever is pulled back and latched in its original position. The interrupter contacts are closed (d) and the opening springs are
extended. The mechanism is now ready for another opening
operation.

HYDRAULIC CONTROL SYSTEM OPERATION
The hydraulic pump, associated cam, and linkages regulate the

The hydraulic pump (Figure 6) is linked to the closing-solenoid
plunger and is pushed downward with each return operation of

the plunger. With its downward stroke, the pump forces a
measured amount of oil under the lockout piston (Figure
7), causing it to rise one step. When the closing coil is energized, the recloser contacts close and the pump returns to its
normal position.
The lockout piston is linked to the sequence selector cam
and the lockout bar. Upward movement of the lockout piston
causes the cam to rotate counterclockwise and the lockout bar
to advance one step. The number of fast operations is preset
on the cam. After these operations, the cam engages the roller
and pushes it to the right. A mechanism arm attached to the
roller engages the time-delay mechanism on each phase. Subsequent operations are then delayed.
When the lockout bar completes its travel, it trips the lockout
latch. Another set of linkages and springs then lock the recloser
contacts open. The quick reset rod is raised, allowing the
hydraulic pump and lockout piston assembly to reset quickly.
The entire pump and sequencing mechanism is now ready for
the next full sequence of operations. For temporary faults that
are cleared before the recloser mechanism reaches lockout,
the hydraulic pump and lockout piston assembly resettles gradually (at a rate of approximately 90 seconds per operation at
25° C) to reset the recloser mechanism.

MAINTENANCE
Frequency of Maintenance
Because reclosers are applied under widely varying operating and climatic conditions, maintenance intervals are best determined by the
user, based on actual operating experience. To assure proper operation, reclosers must be maintained when they have operated the
equivalent of a complete duty cycle and before the dielectric strength
has deteriorated below prescribed levels. In the absence of specific
operating experience, the following procedures are recommended.
• When Type VW, VWV27 and VWV38 reclosers are operated under
usual service conditions as defined in ANSI (American National
Standards Institute) C37.60, “Standard Requirements for Automatic
Circuit Reclosers for Alternating Current Systems,” it is recommended that the following maintenance procedures be performed
at the completion of an equivalent duty cycle.
• However, if the recloser has not completed an equivalent duty cycle
within three years, it is recommended that a Periodic Maintenance
Inspection be performed at that time.
• The bellows used on interrupter moving contact rods have a
mechanical life expectance of 7000 operations. Interrupters must
be replaced when 7000 operations have been accumulated.
CAUTION
After 7000 operations bellows may develop leaks, due to
machanical wear. If a leak developes the interrupter may be
unable to clear load or fault current.

Each periodic maintenance inspection at the completion of an equivalent duty cycle should include at least the following:
1. Bypass and remove the recloser from service.
2. Thoroughly clean exterior of unit.
3. Inspect external components.
A. Check for broken or cracked bushings. Replace as necessary.
(See page 8 for procedure.)
B. Check for paint scratches and other mechanical damage; paint
to inhibit corrosion.
C. Note counter reading and enter in the record log.
4. Perform a dielectric withstand test to check the insulation
level of the recloser and the vacuum integrity of the interrupters.
(See page 7 for procedure.)
5. Manually operate mechanism; operation should match configuration noted on the data plate.
A. Partially untank unit and support head and mechanism assembly with clean wooden blocks.
B. Use manual closing tool to close interrupters.
C. Pull down on strip solenoid trip links until mechanism trips.
NOTE: The force required to pull down the trip-links will be increased
when the time delay units are engaged.

6. Untank the recloser to expose the internal components.
S280-30-7
CAUTION
Be sure the recloser is open (yellow operating handle under
the sleet hood is down) before untanking, so that the mechanism can not be accidently tripped while out of oil.
7. Clean all internal components.
A. Remove all traces of carbon by wiping with a clean, lintfree cloth.
NOTE Although current interruption takes place in a sealed vacuum chamber, the closing solenoid contactor operates in oil and
will produce some carbon deposits.
B. Flush the mechanism with clean transformer oil.
CAUTION
Never use volatile solutions, detergents, or water-soluble
cleaners.
8. Remove bushings.
A. Non oil filled bushing should be dismantled, cleaned and
inspected.
B. Oil filled bushing should be cleaned and inspected. DO
NOT dismantle oil filled bushings.
9. Replace all external seals and gaskets.
10. Inspect mechanism for cracks, carbon tracking, flashovers
or other damage. Repair or replace as required.
11. Check the condition of the closing solenoid contactor contact tips. If the contact tips are eroded replace entire contactor
assembly. (See page 11 for replacement procedure.)
A. An oil sample taken near the bottom of the tank should
have a dielectric strength of not less than 22 kv rms.
B. Low dielectric strength indicates the presence of water or
carbon deposits. Replace the oil as necessary.
12. Inspect closing coil for cracks or other damage.
13. Inspect series trip solenoid.
14. Check the contact erosion of the vacuum interrupters.
A. Locate the scribe mark on the moving contact rod at the
top of the interrupter, Figure 8.
B. If the scribe mark falls below the top of the phenolic guide
when the interrupter is closed, the interrupter has
reached the end of its useful life and must be replaced.
(See page 10 for replacement procedure.)
15. Reinstall bushings, use new gaskets. (See page 8 for installation procedures.)
16. Drain the tank, and clean out all sludge and carbon deposits.
If oil is to be reused it must be filtered and the dielectric
strength checked.
17. Fill with new, clean insulating oil up to 2-1/4 inches below the
top of the tank flange. See Oil Condition on page 8.
18. Clean the head gasket seat and retank the recloser.
A. Move the yellow operating handle under the sleet hood to
the up position to avoid any possible binding while raising the tank.
B. Replace the head bolts and tighten to 35-55 ft-lbs torque.
Apply clamping force gradually and equally, in rotation,
to each bolt to achieve an evenly distributed gasket sealing pressure.
19. Check the oil level with the dipstick in the head and adjust the
level to the upper line on the dipstick.
NOTE: If the recloser is equipped with an oil-sight gage, the oil level
should be above the sight gage. if the oil surface line is visible in the
window, add oil to raise the level to the upper line on the dipstick.
20. Perform high-potential insulation withstand test (page ) to
make sure the dielectric clearances within the tank have not
been compromised. Also, use a suitable tester to verify that
the recloser is operating per data plate specifications.
Manual Operation of the Recloser
The recloser may be closed and opened manually while the
mechanism is either in or out of oil.
MECHANISM IN OIL
For a tanked recloser (mechanism immersed in oil) use the following manual operating procedure.
1. To close the recloser.
A. Remove the closing tool port cover and gasket from the
side of the head casting. (See Figure 2 for location.)
B. Insert the KA9OR T-handle closing tool (furnished as an
accessory) into the closing tool port (Figure 9) and engage
the pin on the closing shaft.
C. Lift up the yellow operating handle under the sleet hood to
reset the mechanism.

High-potential withstand tests provide information on the dielectric condition of the recloser and the vacuum integrity of the
interrupters. Testing is performed at 75% of the rated low frequency withstand voltage (37.5 kv for the VW, 45 kv for the
VWV27 and 52.5 kv for the VWV38).
TEST 1: Proceed as follows:
1. Manually close main contacts of recloser (see page 6 for procedure).
2. Ground recloser tank and head.
3. Connect all three source-side bushings (1, 3, 5) together.
4. Apply proper test voltage to source-side bushings.
5. The recloser should withstand the test voltage for 60 seconds.
TEST 2: Proceed as follows:
1. Manually close main contacts of the recloser (see page 6 for
procedure).
2. Ground recloser tank and head.
3. Ground Phase A (bushing 2) and Phase C (bushing 6).
4. Apply proper test voltage to Phase B (bushing 3).
5. The recloser should withstand the test voltage for 60 seconds.
TEST 3: Proceed as follows:
1. Open main contacts of recloser (see page 6 for procedure).
2. Ground recloser tank and head.
3. Connect and ground all three load-side bushings (2, 4, 6).
4. Connect all three source-side bushings (1, 3, 5).
5. Apply proper test voltage to source-side bushings.
6. The recloser should withstand the test voltage for 60 seconds.
7. Reverse the connections: ground source-side bushings (1, 3,
5); apply test voltage to load-side bushings (2, 4, 6) for 60 seconds.
8. The recloser should withstand the test voltage for 60 seconds.
S280-30-7
TEST RESULTS: These high potential withstand tests provide
information on the dielectric condition of the recloser and the vacuum integrity of the interrupters.
A. If the recloser passes the closed-contacts tests (Tests 1 and 2)
but fails the open-contacts test (Test 3) a deteriorated vacuum
in one or more of the interrupters is most likely the cause.
Retest each vacuum interrupter individually to determine the
failed phase or phases, and replace the interrupter(s). Retest
to confirm the repair.
B. If the recloser faiIs the closed-contacts tests (Test 1 and 2) the
cause is likely to be a diminished electrical clearance or a
failed insulation. After correcting the problem, retest to confirm the repair.
Oil Condition
Oil provides the internal insulation barrier between phases and
from phase to ground, and must be replaced before it deteriorates
below a safe dielectric level. Replace the oil if its dielectric
strength falls below 22 kv.
New oil should always be filtered before use, even though it is
obtained from an approved source. Passing the oil through a blotter press will remove free water and solid contaminants such as
rust, dirt, and lint. Keep aeration to a minimum during filtering to
prevent moisture in the air from condensing in the oil and lowering its dielectric strength.
Used oil must be treated before reusing. Filtering may remove
absorbed and free water and other contaminants to raise the
dielectric strength to acceptable levels. However, filtering does
not always remove water-absorbing contaminants and the dielectric strength may fall rapidly after being returned to service.
Therefore the recloser should be filled with new oil, or oil that has
been restored to like-new condition. Oil used in these reclosers
conforms to ASTM Standard D3487, Type 1; its property limits
are shown in Reference Data R280-90-1, “Oil Specifications and
Tests.”
clockwise to reduce the dimension or counterclockwise to
increase the dimension. Slide the control lever back onto the
shaft and recheck the dimension. When the proper dimension
has been obtained replace the C-ring.
Bushings
Bushing maintenance generally consists of a thorough cleaning
and a careful examination for chips, cracks, or other mechanical
damage during the periodic maintenance inspection. Bushings
must be replaced whenever damage is discovered.
TYPE VW BUSHINGS
A damaged bushing can be replaced with the
recloser either tanked or untanked, depending
upon the circumstance of the damage.
• If the bushing porcelain is accidentally chipped during installation of the recloser, and it is obvious that no other damage has
occurred, the bushing porcelain only can be replaced without
untanking the recloser.
• If the bushing has been damaged while in service or storage,
the recloser must be untanked. Water or other contaminants
may have entered the tank (test the oil) the bushing lead may
be damaged (either mechanically or electrical flashover), or
pieces of porcelain may have fallen into the tank.
Replacing the Bushing Porcelain with the Recloser Tanked
Refer to Figure 13 and proceed as follows:
SHOP MAINTENANCE PROCEDURES
The operations described in this section should be performed
under the cleanest conditions possible. The repair work, except
for bushing replacement, will be simplified if the work bench is
arranged so the mechanism/head assembly can be inverted
(bushings down). No special tools are required for any of the
repair procedures.
Control Lever Overtravel Adjustment
Check for proper adjustment of the control lever by first removing
the sleet hood cover to expose the control lever. From the OPEN
position, slowly push the control lever toward the CLOSED position. As the lever is pushed up, latching of the recloser will be felt.
At this point the dimension between the top of the control lever
and the underside of the sleet hood should be 1/4 inch (Figure
12).
If the control lever is not adjusted properly, remove the C-ring
and slide the control lever from the shaft. Rotate the control lever
Figure 13.
Replacing bushing w/tanked Type VW recloser.
1. Unscrew bushing terminal and discard terminal gasket.
2. Remove three hex head capscrews and clamps that secure
the bushing to head and lift out porcelain.
3. Remove and discard lower bushing gasket.
4. Twist off split aluminum clamping ring from old porcelain. If it is
in good condition install it on new porcelain; replace if damaged.

TYPE VWV27 and VWV38 BUSHINGS
The bushings used on Type VWV27 and VWV38 reclosers are
oil-filled. The special fixtures and procedures required to assemble these bushings is beyond the scope of normal shop maintenance repair. Therefore if an oil bushing is in any way damaged,
the complete bushing assembly must be replaced. Refer to Figure 15 and proceed as follows:
NOTE: Apply a very small amount of petroleum jelly to the
knurled surface of the inside face of the terminal before assembling the terminal to the bushing rod.

Vacuum Interrupters
Vacuum interrupters must be replaced when:
• They lose their vacuum as evidenced by a failure during the low
frequency dielectric withstand test across the open contacts;
• The interrupter contacts have eroded beyond their useful life
as evidenced by the position of the scribe mark on the moving
contact rod; or
• The interrupters have completed their mechanical life of 7000
operations.
To replace an interrupter, refer to Figure 16 and proceed as
follows:

action can be verified by observing the scribe mark on the
contact rod. It will move downward to just above (or below)
the fiber disk at the top of the interrupter.
NOTE: If the contact rod does not move, the interrupter may have
lost vacuum or the contact rod may be sticking in the clamping fingers of the contact operating rod assembly. Use a screwdriver to
gently spread the clamping fingers to free the rod.
4. Disconnect bushing lead from lower contact plate assembly.
5. Loosen and remove lower interrupter clamp.
6. Remove hardware attaching lower contact plate to the three
vertical stringers and remove contact plate and interrupter.
7. Install the new vacuum interrupter into the clamping fingers of
the contact operating rod and the lower contact plate. Attach
the plate to the stringers.
NOTE: On side with the single stringer, a spacer on the stringer stud
provides a 1/16-inch gap between contact plate and the attaching flat
washer and locknut when the interruptercontacts are open. This gap
is intentional.
8. Manually close recloser.
9. Coat threads of interrupter clamps and attaching screws with
a film of transformer oil and loosely install.
10. Rotate interrupter so that one of the hex nuts at the top of the
interrupter is centered directly beneath the gap on one side
of the upper clamp. (See Figure 17.)
11. Position the upper and lower interrupter clamps just below the
shoulder on the finger-type current exchange connectors so
clamping force will be applied to the center of each finger, as
shown in Figure 17.
CAUTION
When rotating the interrupter avoid twisting the contact rod
to prevent damaging the bellows and destroying the interrupter.
12. Tighten screws of each interrupter clamp evenly to 75 in-lbs

Closing Solenoid
The closing solenoid coil is connected phase-to-phase and is
rated to operate at full system voltage. It is protected with two
fuses, one on either side. A data plate attached to the recloser
head between source side bushings 3 and 5 provides the coil
connection information. If the solenoid coil must be replaced, due
to damage or
change in operating voltage, refer to Figure 19 and proceed as
follows:
1. Disconnect the two coil leads from closing solenoid contactor.
NOTE: Reattach the lockwashers and nut to the contactor terminal
immediately after disconnecting the coil lead to prevent loss of parts
of the moving contact arm assembly which is attached to the support
plate with the same hardware.
2. Remove four capscrews and lockwashers which attach base
plate to bottom of solenoid frame posts and lower coil and
base plate.
3. Remove coil from the base plate and discard coil gasket.

SERIES TRIP SOLENOID
The continuous current rating and the trip current rating of the
recloser can be changed by installing new coils in the series trip
solenoids. Tripping occurs at about 200% of the continuous current rating of the standard coil and at about 140% when the alternate (400X or 560X) coils are used. The maximum interrupting
rating of the recloser is dependent upon the continuous current
rating of the series trip coil.
Two different coil replacement kits are required. One for Phase A
and Phase B solenoids and another for Phase C (the interrupter
furthest away from the sleet hood) which has an opposite wind
because it mounts differently on the interrupter. The same basic
replacement procedure is used for either type coil.

The recloser is equipped with hydraulically-operated time delay
units on each phase. These provide the different time-current
characteristic (TCC) curves, as shown in Reference Data
R28091-6. Each unit can provide either of two-time delay characteristic curves, but not all four (KA1 194R1 provides B and C
curves and KA1194R2 provides D and E curves).
When the mechanism is sequenced to the delayed operation
phase, the latch assembly of the trip-coil plunger linkage is
engaged with the arm of the time-delay unit, this provides consistent delay action by forcing hydraulic fluid through an orifice in
the unit. Special aircraft-type fluid is used to minimize temperature effects.
Maintenance
Figure 20.
Series trip solenoid removal.
84613KMA
Solenoid Replacement
Check lower coil washer before installing new coils. For coils
rated 280 amperes and below the upper and lower coil washers
are identical. For 400 and 560 ampere rated coils, the lower
washer requires a larger center slot. The same upper washer is
used with all coil sizes.
1. Pass upper insulating washer over terminal strap and align its
slot with the coil slot (Figure 21).
2. Insert coil into the frame and slide the upper coil washer into
position.
Maintenance to the time delay units is limited to checking the fluid
level in the units. Some loss of fluid is normal, therefore this
inspection should be made each time periodic maintenance is
performed.
To check the fluid level, remove the socket-head filler plug
located on the side of the unit. Add enough fluid to bring the level
up to the filler plug hole. Avoid introducing dirt, lint or any other
foreign material when filling the unit as this can plug the orifice
and cause erratic time-delay action.
NOTE: A special fluid replacement kit, catalog number KA806R2, is
available. The kit consists of approximately 60 cc (2 US fl. oz. ) of the special hydraulic fluid in an eye-dropper bottle.

Replacement
Replacement time-delay kits include a factory calibrated time
delay, four flat head screws and a minimum-trip calibration
spring. Remove the malfunctioning unit and install the replacement in its place (see Figure 22).
The minimum trip setting of the recloser must be recalibrated
by adjusting the spring tension whenever a new time-delay unit
is installed.

Removing Mechanism from Head
To gain access to components located in or on the main frame,
the following procedure may be used to remove the mechanism
from the head.
NOTE: These procedures will be simplified if the untanked head and
mechanism assembly can be inverted (bushings down). The unit can be
supported on its bushings.
1. Disconnect all six bushing leads from the ends of the bushings.
2. Disconnect the lockout lever and contact position indicator
shafts by disengaging the spring loaded couplers and locking
them in the disengaged position, Figure 23.
3. Disconnect any accessories, such as a ground trip solenoid,
at their terminals.
4. If the recloser is equipped with the auxiliary switch accessory,
remove the C or E-ring and washer, Figure 24, and disconnect the operating lever of the switch from the recloser mechanism.
5. Remove the six socket head bolts and lockwashers that
secure the frame to the head casting and carefully lift the
mechanism from the head. Six long pipe spacers will be
released when the mechanism is lifted.
NOTE: By temporarily substituting eye-bolts for two of the hex head
bolts in the bottom of the closing solenoid frame, the mechanism can
be easily lifted and handled with a hoist.
6. Remove couplers from contact position indicator and lockout
lever shafts.

Reinstalling Mechanism into Head
To reinstall the recloser mechanism assembly into the head, the
following procedure may be used.
1. Install the couplers on the lockout lever and contact position
indicator shafts. Lock them in the disengaged position.
2. Carefully lower the mechanism assembly onto the six pipe
spacers which have been positioned over the mounting holes
in the casting.
3. Install the six socket head bolts and tighten evenly to avoid any
binding of the mechanism.
NOTE: Replace the hex head bolts in the bottom of the closing
solenoid frame if eye-bolts were used for handling the recloser
mechanism.
4. Re-engage the lockout lever and contact position indicator
shaft by releasing the shaft couplers.
5. Reconnect the operating lever of the auxiliary switch (if used)
to the mechanism and secure with the washer and E-ring
(Figure 24).
6. Reconnect the bushing leads to the end of the bushings.
