wall. Pry the loose ends of the bushing

up with an awl and remove the bush-

ing.

To remove the rear bushing, use the

tool shown in Fig. 48, and press the

bushing from the drum.

Assembly

1.
If the clutch drum bushings were

removed, position the drum in a press

and press new bushings into the drum

with the tools shown in Figs. 48 or 49.

2.
Dip the new seals in transmission

fluid and install one on the drum and

one on the piston.

in the piston sockets. Place the spring

retainer on the springs.
5.
Install Tool T65L-77515-A (Fig.

46) and compress the springs. Make

certain that the spring retainer is cen-

tered while compressing the springs.

Install the snap ring. Before releasing

the pressure on the tool, make certain

that the snap ring is positioned inside

of the four snap ring guides on the

spring retainer.

6. Clutch plate usage varies with

each model, refer to the Specifications

Section for the number of plates re-

quired. Dip the clutch plates in clean

transmission fluid. Install the clutch

plates alternately starting with a steel

drive plate (Fig. 45).

7.
After all clutch plates have been

installed, position the pressure plate in

the clutch drum. Install the pressure

plate snap ring.

8. With a feeler gauge, check the

clearance between the pressure plate

and snap ring (Fig. 50).

9. The pressure plate should be held

downward as the clearance is checked.

Refer to the Specification Section for

the proper clearance. If the clearance

is not within specifications, selective

thickness snap rings are available in

the following thicknesses: 0.065-0.069,

0.074-0.078, and 0.083-0.087 inch. In-

stall the correct size snap ring and re-

check the clearance.

sion fluid. Install the smaller seal on

the clutch hub and the other seal on

the clutch piston.

2.
Install the clutch piston in the

cylinder.

3.

with the dished face downward. Install

the spring as shown in Fig. 56. Secure

the disc with the retaining snap ring.

4.
Install the forward pressure plate

with the flat side up and the beveled

side downward. Install first a compos-

ition driven plate and a steel drive

plate (Fig. 52). Install the remaining

plates in this sequence. Refer to the

Specification Section for the number

of plates required. The last plate in-

stalled will be the rear pressure plate.

Install the snap ring and make certain

that it seats fully in the groove.

5.
With a feeler gauge, check the

clearance between the snap ring and

the pressure plate (Fig. 55). Down-

ward pressure on the plate should be

maintained when making this check.
