trained and experienced with Hartzell Propeller Inc. products.
(a)
(7)
This manual does not provide complete information for an inexperienced
technician to attempt DT-1724-3(F) rolling machine maintenance without
supervision.
This manual is intended to be the primary source of maintenance information

B. Item References
(1)
Item references throughout the text in this manual refer to item numbers in
the Illustrated Parts List chapter of this manual. The item numbers appear in
parentheses directly following the part name. Only the item base number will
appear in the text of the manual. Item base numbers and the alpha variants of
the base numbers will appear in the illustrated parts list. There are two reasons
for the use of alpha variants:
(a)
A part may be superseded, replaced, or obsoleted by another part. For
example, the pitch change block unit (105733) that is item 320 was
superseded by the pitch change block unit (105733-1) that is item 320A.
(b)
An Illustrated Parts List may contain multiple configurations. Effectivity
codes are used to distinguish different part numbers within the same list.
For example, one configuration may use a piston (B-2419) that is
item 80, yet another configuration uses a piston (104256) that is
item 80A. Effectivity codes are very important in the determination of parts
in a given configuration.

1. Description
A. DT-1724-3(F) Rolling Machine Principles of Operation
(1)
The roller portion of the unit consists of a roller head that rotates to follow the
blade retention radius.
(a)
(2)
The roller assembly uses a small, reversible motor to drive a geared wheel to
which the roller head is attached. As this wheel rotates, it rotates the roller head
through the required radius.
(a)
(3)
This unit is mounted on a carriage that moves parallel to the blade
centerline to extend the rolled area beyond the radius.
The range of movement of the roller is controlled by a microswitch placed
at each end of travel.
The carriage movement is controlled automatically by an electric motor.
(a)
The rolling operation begins with the carriage full forward (nearest the
blade butt).
(b)
Once the roller head has ­proceeded through the radius portion of the
rolling process, the carriage will begin to move toward the tip of the blade,
­parallel to the blade centerline.
(c)
The roller pressure is gradually decreased to zero.
(1)
(4)
The reduction of roller pressure is ­accomplished by releasing the
hydraulic pressure, which is ­automatically controlled by a mechanical
check valve installed in the air line.
The carriage traverse motor controls the forward and aft ­movement of the
carriage.
(a)
Start and stop action is controlled by microswitches located at the stops at

3. Machine Functional Test After Machine Components Replacement
Following the replacement of certain components in accordance with Table 3-2 of the
Repair and Replace chapter and reassembly of the DT-1724-3(F) rolling machine, two
tests must be made to make sure that the machine is working properly; (1) an applied
load measurement that measures the force being applied by the roller to the shank, and
(2) the rolling of a test blank for evaluation purposes.
A. Applied Load Measurement
(1)
Install the load cell fixture on the fixture (340).
NOTE:
The load cell fixture is used as a support for the load cell to rest against.
CAUTION:
MAKE SURE THE FIXTURE (340) IS IN THE LOCKED
POSITION AND THAT THE ROLLER HEAD IS
PERPENDICULAR TO THE BLADE IN THE "HOME" POSITION.
(2)
Using a square, line up the surface of the load cell fixture closest to the
roller (1120) to be perpendicular to the base (342).
(3)
Loosen the "L" Gibs (780) and slide the roller head assembly back to permit
room for the load cell.
(4)
Using a 1/4 spacer between the roller arm (1110) and pivot block (1060), slide
the roller head assembly forward until the roller (1120) contacts the load cell
that is positioned between the roller and load cell fixture.
(5)

Put an indicator on the base (342), at the end of the carriage (1010), to monitor
the relative position of the roller (1120) to the blade shank.
(a)
(6)
The indicator must have a minimum travel limit of 1.25 inches (31.8 mm).
Monitor the setting of the air control arm (100). This setting controls the
distance that full pressure is applied after the roller (1120) passes the tangent
point of the radius, after the carriage (1010) starts to move.
(a)
Monitor the distance that the carriage (1010) moves before the air
pressure begins to be released by the air switch (130).
(1)
The carriage (1010) movement distance must be 0.125 ±0.050 inch
(3.18 ±1.27 mm).

4. Evaluation of Test Specimen
A. Required Component Checks After Replacement
(1)
Following the replacement of any of the components listed in Table 3-2 of the
Repair and Replace chapter in this manual, perform the following checks:
(a)
Before beginning the rolling process, examine the contour of the retention
radius on the optical comparator, using a mylar overlay. Refer to Appendix
A - Optical Comparator chapter in the Hartzell Propeller Inc. Aluminum
Blade Overhaul Manual 133C (61-13-33).
NOTE:
The radius of the sample must conform to the optical
comparator overlay. If the radius does not conform to the optical
comparator overlay, use a different sample.
(b)
After the rolling process is completed, using a profilometer TE436
measure the surface finish of the rolled radius and transition area of the
blade shank in accordance with the Overhaul Procedures section in the
Blade Shank Overhaul chapter of Hartzell Propeller Inc. Aluminum Blade
Overhaul Manual 133C (61-13-33).
(c)
After the rolling process is completed, reinspect the blade shank on the
optical comparator to make sure the rolling process did not change the
shape or contour of the radius.
(d)
If the shape or contour of the radius was changed by the rolling process,
refer to the section, "Failure of Test Roll Specimen" in this chapter.
(e)
The surface of the radius and shank must meet the dimensional
requirements and must meet or exceed the surface finish requirements as
shown in Figure 4-3.
(f)
Examples of unacceptable surface conditions are indents, pits, ridges,
or abrupt transitions. Unacceptable conditions must be polished out in
accordance with the limits as shown in Figure 4-3, and the blade retention
radius must be re-rolled.

1. Introduction
A. General
(1)
The Illustrated Parts List contains the current configurations for the
DT-1724-3(F) rolling machines manufactured by Hartzell Propeller Inc. included
in this manual and supersedes any prints that may have previously been
supplied for part and assembly information. The parts list contained within the
Illustrated Parts List is to be used to make sure of the configuration of the
DT-1724-3(F) rolling machines and for ordering parts.
CAUTION:
(2)
ILLUSTRATIONS IN THE ILLUSTRATED PARTS LIST ARE TO
BE USED FOR IDENTIFYING PARTS AND SHOULD NOT BE
USED AS A MAINTENANCE REFERENCE FOR ASSEMBLY.
Figures are for reference only. The figures provide general views of parts. For
ease of illustration, typical views of some parts were created and shown in
multiple figures. For this reason, illustrated parts may not exactly reflect parts
contained in some DT-1724-3(F) rolling machines.
B. Using the Illustrated Parts List
(1)
If a repair station has questions about the DT-1724-3(F) rolling machines as
stated in the Illustrated Parts List, contact the Hartzell Propeller Inc. Product Support
Department.
2. Description of Columns (Rev. 1)
A. Fig/Item Number
(1)
Figure Number refers to the illustration where items appear. Item Numbers refer
to the specific part callout in the applicable illustration.
(a)
Item Numbers that are listed but not shown in the illustration are identified
by a dash to the left of the item number. (example: "-800")
(b)
Alpha variants will be used to add additional items. There are two reasons
for the use of alpha variants:
1
A part may have an alternate, or may be superseded, replaced, or
obsoleted by another part.
a
2
For example, the self-locking nut (A-2043) that is item 20 was
superseded by the self-locking nut (A-2043-1) that is item 20A.
An Illustrated Parts List may contain multiple configurations.
Effectivity codes are used to distinguish different part numbers within
the same list.
a
For example, one propeller configuration may use a mounting
bolt (B-3339-1) that is item 30, yet another propeller
configuration uses a mounting bolt (B-3347) that is item 30A.
Effectivity codes are very important in the determination of parts
in a given configuration.

D. Description
(1)
This column provides the Hartzell Propeller Inc. description of the part.
(2)
Bullets and indentations are used to indicate parts that are components of a
sub-assembly.
(a)
For example, a Fork Assembly that is part of a HC-C2YR-1 propeller
assembly will have one bullet ( • ) before the description. This indicates
that the Fork Assembly is part of the propeller assembly.
1
A Fork Bumper that is part of the Fork Assembly will appear
directly below the Fork Assembly with two bullets ( • • ) before the
description. This indicates that the Fork Bumper is part of the Fork
Assembly - that is part of the Propeller Assembly.
a
Example:
HC-C2YR-1
• Fork Assembly
• • Fork Bumper
(3)
If the description in this column includes a "PCP:" prefix, the part is classified as

service document number related to the change may be included for
reference.
If applicable, vendor CAGE codes will be listed in the Description column.
E. Effectivity Code (EFF CODE)
(1)
(2)
This column is used when additional information about a part is required.
(a)
Effectivity codes can be used to identify parts that are only used on a
particular model, or to direct the user to additional information in the
"Effectivity" box at the bottom of the page.
(b)
Whenever an effectivity code is present, refer to the "Effectivity" box at the
bottom of the page for the applicable information.

Propeller Inc. manuals have previously been specified with AN, MS, NAS, or
vendor part number. To provide internal controls and procurement flexibility,
Hartzell part numbers have been assigned to all O-rings, fasteners, and
hardware. Part shipments from Hartzell Propeller Inc. will specify only the
Hartzell part numbers.
(2)
Some O-rings, fasteners, and hardware manufactured in accordance with
established industry specifications (certain AN, MS, NAS items) are acceptable
for use in Hartzell Propeller Inc. products without additional standards imposed
by Hartzell.
