surface, drill a 1/8 inch diameter hole

through the center of the cupped plug.

Pull the plug from the case with a

wire hook.

4.
Lift the end of the spring off the

park plate pin to relieve the tension.

5.
Thread a
1/4-20
inch or # 8-32

x 1 1/4 inch screw (Fig. 34) into the

par1: plate shaft. Pull the shaft from

the case with the screw.

6. Position the spring and park

plate in the case and install the shaft.

Hook the end of the spring over the

pin on the park plate.

7.
Install a new cupped washer

(Fig. 33) to retain the shaft.

8. Install the parking pawl shaft in

the case. Slip the parking pawl and

spring into place on the shaft.

case making sure that the actuating

rod is seated in the slot of the plate.

Secure the plate with two bolts and

lock washers.

Servo Apply Lever

1.
Working from inside of the

transmission case, carefully drive on

the servo apply lever shaft to remove

the cup plug. The shaft (Fig. 35) can

be withdrawn from the case by hand.

2.
Hold the servo apply lever in

position and install the new shaft.

3.
Using the fabricated tool shown

in Fig. 35, drive the cup plug into

erbore. The cup plug may be coated

with Loctite, Part No. C3AZ-

19554-A, before installation.

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 size threads as the

thread OD. For example, use a 5/16-

inch drill when repairing a 5/16-18

inch thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

with the repair kit marked 5/16-18

will not cut the same thread as a

standard 5/16-inch tap. It will cut a

thread large enough to accommodate

the insert, and after the insert is in-

stalled, the original thread size (5/16-

18 inch) 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.
