Inspect and measure bushing (23) inside end of output shaft (22) for damage or wear. The maximum ID of bushing is

1.423 in (36.14 mm).

WARNING

Rear cover spring and retainer assembly contains highly compressed springs. Be extremely careful during

disassembly. Personal injury can occur if spring force is not controlled.

Remove C5 clutch piston (18) from rear cover (3) by compressing spring and retainer assembly (17), using tool

(J37030-3) tool base, washer, bearing, handle, and piston compressor (J37030-2). Remove retaining ring (19) and

slowly release spring force.

10.

Remove outer seal ring (20) and inner seal ring (21) from C5 clutch piston (18).

11.

Inspect bearing cup (16). If worn or damaged, remove using tool (J3940).

If removed, install new bearing cup (16), using bearing tool (J37033) and drive sleeve tool (J37034).

Install inner seal ring (21) and outer seal ring (20) onto C5 clutch piston (18).

Align tang notch on rear of C5 clutch piston (18) with tang in rear cover (3), while installing C5 clutch piston into rear

cover.

Install spring and retainer assembly (17) while aligning tab in spring and retainer assembly with notch in rear cover (3).

WARNING

Rear cover spring and retainer assembly contains highly compressed springs. Be extremely careful during

assembly. Personal injury can occur if the spring force is not controlled.

Compress spring and retainer assembly (17) using (J37030-3) tool base, washer, bearing, handle, and piston spring com-

pressor (J37030-2). Install retaining ring (19) and slowly release spring force.

If removed, install cone and roller bearing (2). Use driver sleeve tool (J37034) and press bearing against shoulder on P3

planetary carrier (1).

If removed, press bushing (23) inside end of output shaft (22) using installer tool (J37036) and a press.

Install output shaft (22), thrust washer (6), and retaining ring (7).

Install two bearing assemblies (8) into center of pinion gear (13). Install thrust washers (9 and 14) inside P3 planetary

carrier (1), align thrust washer tangs with slots in planetary carrier, and retain them with petrolatum. Slide pinion gear

and bearing assemblies into side of P3 planetary carrier between thrust washers. Repeat procedure for remaining three

pinion gears.

10.

Install four pinion spindles (15) so that lower step is positioned for proper installation of indexing ring (5).

11.

Install indexing ring (5) and retaining ring (4).

12.

Measure pinion end play. Pinion end play must not exceed 0.037 in (0.94 mm). Check all four pinions.

13.

Place P3 planetary carrier assembly (1) on work bench with output shaft up. Place rear cover (3) over output shaft.

14.

If removed, install cone and roller bearing (12) into rear cover assembly (3) using drive sleeve tool J37034.

15.

Install new locknut retainer (11).

CAUTION

Over-tightening bearing retainer locknut will damage cone and roller bearing assembly.
