PSP FOR REWORKING AND UPDATING THE WINCH ON CERTAIN 518 SKIDDERS - PS4458 - MAILED US AND CANADA Caterpillar

U-207
5163   PS4458
NOTE: This Program can be administered either before or after a
failure. In either case the decision whether to apply the
Program is made by the dealer. When reporting the repair, use
"PS4458" as Part Number, "7755" as Group Number, and "96" as
Description Code.

October 31, 1991

Changes have been made to improve the service life of 518 Winches on certain
518 Skidders.
Segment A: An improved bearing replaces the former bearing used on the input
clutch shaft. A new gear with wider teeth and improved support (2 bearings)
replaces the former gear that has failed under high loads. A new
shaft, spacer, hub, and housing are also added to facilitate the new gear
design. The clutch manifold and spring retainer are reworked; and the
assembly method has been modified to insure sufficient retraction and
clamping force of the clutch.
Segment B: An improved shifting fork, improved coupler, and springs with
heavier loads replace the former shifting fork, coupler, and springs in the
freespool mechanism. A cover is also reworked to accommodate the new
freespool mechanism. A cover is also reworked to facilitate the new
freespool mechanism. The gear can be replaced if damaged.
Segment C: A new drum shaft with improved bending strength replaces the
former shaft. New double lip drum seals replace the former single lip seals.
A new gear and sleeve are also added and the retainer is reworked to
accommodate the new seal design. A new drum drag brake plug made of material
that is more resistant to swelling in the presence of oil will replace the
former plug. A new drum with thicker flanges and larger drum diameter
replaces the former drum. (Note: The drum change is optional.)
Segment D: A higher capacity one-way clutch replaces the former one-way
clutch. A new support is used to accommodate the new one-way clutch. A new
bevel gear/brake shaft uses a longer bolt to fasten an improved viscous brake
disc and a new reaction plate to the brake shaft. The new viscous brake
reaction plate is fastened to a new one-way clutch hub with a dowel to
prevent rotation of the plate that may have previously contributed to bolt
loosening. The former piston is reworked to prevent sticking.
Segment E: A new bevel gear/brake shaft uses a larger diameter bolt to
fasten the gear/bearing retainer plate to the shaft. The former bolt
experienced loosening/breaking. A new plate and cage is also added to
facilitate the new bolt design.
Segment F: An improved pinion and bevel gear replaces the former pinion gear
and bevel gear which experienced gear tooth pitting and wear in certain
applications. The new pinion was also redesigned to prevent axial movement
of the pinion.
Segment G: Reinforcement of the case assembly will prevent case assembly
deflections that caused drum shaft breaking and improve pinion service life.
Segment H: An improved spring replaces the former spring in the power train
oil system priority valve. The former spring could relax and cause low winch
control pressure.

SEGMENT A - INPUT CLUTCH REWORK
1. Remove and disassemble the input clutch using the instructions in the
518 Winch D & A service manual.
2. Rework the 7G4969 Manifold by increasing the depth of the bore for the
piston. See Illustration 1. Use care when machining the manifold to
keep from damaging the existing bore where the piston seal travels. (No
tool drag out marks are allowed.)
Stamp the letter "R" near the part number to show that the manifold has
been reworked.
3. Rework the 7G4977 Retainer by removing material from the spring face of
the retainer. See Illustration 2.
Stamp the letter "R" near the part number to show that the retainer has
been reworked.
4. Replace the former parts with new parts shown in the list below.

5. Assemble input clutch using instructions in the 518 Winch D & A Service
Manual and the following instructions:
A) Install only six of the 1V8784 Springs in the 7G4977 Retainer. The
two spring holes in the retainer that are not used must be 180 deg.
opposite each other.
B) During assembly of the clutch with the shorter (reworked) 7G4977
Retainer, the retainer, 7G4969 Manifold, and bearings must be
pressed against one another on the shaft. When assembling winches
with the shorter retainer and the six springs, it will be necessary
to check the end play of components on the input shaft and shim as
necessary.
C) To check end play it will be necessary to assemble all the input
clutch components including the bearing cage (cover). Position a
dial indicator against the input gear and move the input shaft
axially. Measure the amount of end play (amount the gear moves)
and use 091133 Shims at the location shown. Use as required to
obtain 0.25 - 0.75 mm end play. See Illustration 3.
SEGMENT B - IDLER GEARS AND FREESPOOL REWORK
1. Remove and disassemble the idler gears and freespool mechanism using the
instructions in the 518 Winch D & A Service Manual. Omit Step nos. 3,
13, 14 and 15.
2. Rework the 9W1505 Cover by increasing the depth of the 38.0 +/- 0.5 mm
dia bore to 34.5 +/- 0.5 mm. See the following Illustration 4.
3. Replace the former parts with new parts shown in the list below.

Note: Make the following changes to the "Pressure Chart
for Winch" on page 33 of the Service Manual.
a. In the column "Engine Speed", change all four speeds to
"low idle".
b. Add footnote: All pressure readings to be taken with
transmission in "neutral". If the transmission is in
gear, the priority valve reading is higher than in
"neutral" because it is the same as the transmission
pressure.

Winch Case Reinforcement Procedure
NOTE: Follow the instructions in this procedure. Failure to do so may
result in bore distortion.
Welding Information
Use ER-70-S3 Solid Wire, .045" diameter.
Wire Feed Speed - 180"/min, @ 18-19 Volts
75% argon, 25% carbon dioxide.
NOTE: Unless other wise specified, all welds are 6 mm intermittent
fillet welds, 25 mm long with 50 mm center.
NOTE: Welds must be cool to the touch (bare hand) before welding
adjacent to welds.
NOTE: Care must be taken to prevent damage from weld splatter to all
machined and sealing surfaces.
NOTE: It may be necessary to grind plates to provide desirable fit-up
with adjoining components.
1. Remove the winch from the machine and remove all components from the
winch case.
2. Assemble the former winch drum shaft and related components into the
winch case. See Illustration 1.
3. Remove paint from areas which are to be welded on winch case.
4. Position Items #1 as shown in Illustration 2. (Page 11 of 18) Tack
weld Items #1 to the winch case.
5. Position Item #2 as shown in Illustration 2. Tack weld Item #2 to Items
#1.
6. Cut tack welds which fasten Items #1 to the winch case. Remove Items #1
and Items #2 as a unit.
7. Weld Item #2 to Item #1 as shown in Illustration 2 (not necessary to
allow welds to cool before completing welds).
8. Set aside to cool. It will be welded to the winch case later in the
procedure.
9. Place Item #3 in position as shown in Illustration 3, Section B-B.
(Pages 12 and 13 of 18) Assure that the plate fully contacts the front
of the winch case and the back of the pinion bearing mounting bracket.
Tack weld in place to only the front of the winch case and pinion
bearing mounting bracket.
10. Place Item #4 in position shown in Illustration 3, Section C-C. Assure
that the plate fully contacts the front of the winch case. Tack weld in
place to only the front of the winch case.
11. Weld Items #3 and #4 to only the front of winch case or pinion bearing
mounting brackets, using dimensions shown, alternating between each
plate until weld is completed.
12. Position the rear of Items #3 and #4 so they fully contact the winch
case. Tack weld in place.
13. Weld Items #3 and #4 to the winch case, using dimensions shown,
alternating between each plate until weld is completed.
14. Position Item #5 as shown in Illustration #2, Section F-F. Tack weld in
place. (Page 16 of 18.)
15. Position Item #6 as shown In Illustration #2, Section H-H. Tack wend in
place. (Page 17 of 18.)
16. Position Item #7 as shown in Illustration #3, Sections C-C and D-D.
Tack weld in place. (Page 5 and 14 of 18.)
17. Weld Items #5, #6, and #7 to the winch case using dimensions shown,
alternating from plate to plate until welds are complete.
18. Cut away flange on winch case as shown in Illustration #3, Section K-K.
(Page 18 of 18.)
19. Position Items #1, and #2, welded together in Step #7, using the
dimension in Illustration #2. Weld in place.
20. Remove drum shaft and clean winch.
