BEFORE YOU BEGIN:
POLE
ADJUSTING BOLT &
ADJUSTING BOLT LOCKNUT
• PHYSICALLY LOCK OUT AND TAG THE CONVEYOR AT THE
POWER SOURCE.
• Double-check the blade type needed for your application: F-Blade - for mechanically spliced belts.
C-Blade - for Flexco® Solid Plate mechanically spliced and
vulcanized belts.
V-Blade - for vulcanized belts. Can be used with mechanical
splices that are recessed (skived) into the belt cover (bolts must
be ground on plate fasteners).
• For chute mounting it is necessary to cut an access hole to allow
for installation and inspections. See dimension requirements on
the back page.
• Follow all safety precautions when using a cutting torch.
• If welding, protect all fastener threads from weld spatter.
• For cleaner clearance requirements see chart.
CLEARANCE
STEP 1. Choose the position on the
conveyor where the cleaner will be
installed (Fig. 1).
Belt Direction
6-8"
6-8"
The Belle Banne® U-Type® Belt Cleaner may be
positioned at any spot from where the belt leaves
the head pulley on down the conveyor line (see
positions A to B). If a chute area is too small due
to a snub pulley, it may be necessary to mount the
cleaner behind the chute (see position C). In chute
applications a minimum of 6"-8" (150mm-200mm)
is required between the cleaner and the chute wall
to prevent clogging of material.

STEP 2. Install the mounting brackets onto the structure.
a. Using the 16" x 24" square, lightly raise the return side belt (take out cupping or sagging on edges) to find
the belt's true parallel path to the structure; and mark reference point #1 on the structure on both sides of the
conveyor. Measure down 3-3/8" (84mm) from reference point #1 on both sides and mark reference point #2
(Fig. 2a).
b. Position the mounting brackets so the centerline marks on the brackets are in line with reference points #2 on
the structure (Fig. 2b).
c. Clamp or weld into position.

STEP 3. Install the cleaner pole into the bearing mounts in both mounting brackets.
a. Remove the nylon bearings from both of the bearing mounts. Remove the spring clip and pull retaining pin out
of one bearing mount. Slide the cleaner pole into the bearing mount on the opposite side and then position it
into the bearing mount where the retaining pin was removed. Reinsert the retaining pin and lock into place with
the spring clip (Fig. 3a).
b. Slide a nylon bearing onto each pole end with the flanged end facing away from the belt. The nylon bearing will
fit snugly into the bearing mount (Fig. 3b).
c. Position the pole so that the blade is centered to the belt. With the blade centered, draw a line around the pole
at the nylon bearing. This line can be used as a reference point to ensure the pole/blade remains centered to
the belt while other steps are completed.

STEP 4. Install the stop collars.
a. Slide one stop collar onto the most convenient pole end (Fig. 4a).
b. Insert a screwdriver or small rod into the hole on the end of the cleaner pole. Pushing on the rod, move the
blade into a positon parallel to the belt (Fig. 4b). The blade should not be touching the belt at this time.
c. Tighten the stop collar set screw and lock nut to hold the blade parallel to the belt.
d. Install the second stop collar on the other pole end. Do not tighten the set screw and lock nut at this time.
STEP 5. Make the final adjustment of the blade to the belt.
a. Loosen the bearing mount set screws and lock nuts. Adjustments will be
made by turning the adjusting bolts either up or down (Fig. 5).
b. Adjust the blade either up or down until both blade ends and the center
make full contact with the belt.
IMPORTANT: In some cases, due to irregular belt wear or cupping, it
may be necessary to make final adjustments independently on both
sides.
c. Tighten the lock nuts on the adjusting bolts to secure the blade in the
correct position. Also tighten the bearing mount set screws and lock nuts.

STEP 6. Mount the tensioning system.
a. Slide one adjusting arm onto the pole end with the stop collar that was not tightened (Fig. 6a).
b. Assemble the tension spring and the J bolt mount to the adjusting arm. Locate the position for the
J bolt mount (Fig. 6b). IMPORTANT: Allow at least 2" (50mm) of upward movement for the J bolt end for
future adjustment.
c. The J bolt mount can be mounted in any position (360 degrees) around the pole. The only requirement is
that the J bolt and spring remain perpendicular to the adjusting arm (Fig. 6c).
d. Weld or bolt the J bolt mount into position.
e. Tighten the adjusting arm set screw and the lock nut to secure the position on the pole.
f. Adjust J bolt to apply light tension on tension spring (For instructions, see Step 8. Some tension must be
applied before repositioning the stop collar on the other pole end in Step 7a).

a. Loosen the stop collar installed in Step 4 (Fig. 7).
b. Slide the second adjusting arm on the pole end;
assemble and mount the tensioning system. Refer to Step 6.
a. Loosen the J bolt jam nuts and turn the
tensioner adjusting nuts until both springs have
a clearance of about .030" between all coils (use
Spring Tension Gauge included in the installation
instruction packet.) (Fig. 8). IMPORTANT: Always be sure there is uniform contact between
the blade and the belt.
b. If the blade is not in full contact with the belt at
the edges and the center, either raise or lower
the pole position of the cleaner and reapply the
tension.

Set both stop collars to a clearance of 1/4" (6mm) for UV
and UC cleaners, or 1/2" (13mm) for UF cleaners, from
the bearing mount stops (Fig. 9). This is to prevent the
blade from moving into the belt. Tighten set screws and
lock nuts.
