PARTS REPAIR OR

REPLACEMENT

During the repair of the sub-

assemblies, certain general instructions

which apply to all units of the trans-

missions must be followed. These in-

structions are given here to avoid un-

necessary repetition.

Handle all transmission parts care-

fully to avoid nicking or burring the

bearing or mating surfaces.

Lubricate all internal parts of the

transmission before assembly with

clean automatic transmission fluid. Do

not use any other lubricants except on

gaskets and thrust washers which may

be coated with vaseline to facilitate

assembly. Always install new gaskets

when assembling the transmission.

Tighten all bolts and screws to the

recommended torque as outlined in

the Specification Section.

TRANSMISSION CASE AND

LINKAGE REPAIR

Low-Reverse Servo

1.
Remove the four servo cover-

to-case attaching bolts. Remove the

vent tube and retaining clip from the

case.

2.
Remove the servo cover, cover

seal, servo piston and piston return

spring from the case (Fig. 43).

3.
The servo piston seal is bonded

to the piston. If the seal has to be re-

placed, replace the piston assembly

which includes the seal. Disassemble

the servo piston from the piston stem

by inserting a small screwdriver in the

hole of the piston stem and removing

the piston attaching nut (Fig. 44).

Position the accumulator spring and

spacer (Fig. 43) on the piston stems.

Make sure the crowned side of the

spring is facing toward the rod. Install

the new servo piston and attaching nut

Thread Repair-Case

Thread service kits may be pur-

chased from local jobbers or the

Heli-Coil Corporation. To repair a

damaged thread, the following proce-

dures should be carefully followed.

1.
Drill out the damaged threads,

using the same drill size as the thread

01).
For example, use a 5/16-inch

drill for a 5/16-18 thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

paired. Thus, the special tap marked

5/16-18 will not cut the same thread

as a standard 5/16-18 tap. It does cut

a thread large enough to accommo-

date the insert, and after the insert is

installed the original thread size

(5/16-18) is restored.

3.
Select the proper coil inserting

tool. These tools are marked with the

thread size being repaired. Place the

insert on the tool and adjust the sleeve

to the length of the insert being used.

Press the insert against the face of

the tapped hole. Turn the tool clock-

wise and wind the insert into the hole

until the insert is 1/2 turn below the

face.

4.
Working through the insert, bend

the insert tang straight up and down

until it breaks off at the notch.

5.
If the inserts are not properly in-

stalled, they can be removed with the

extractor tool. Place the extractor tool

in the insert so that the blade rests

against the top coil 1/4 to 1/2 turn

away from the end of the coil. Tap

the tool sharply with a hammer so

that the blade cuts into the insert.
