Rotating Clutch Module Assembly

If rotating clutch hub bushing (25) was removed, install new bushing using tool (J37040).

Install piston seal ring (26) on clutch hub (6), and piston seal ring (27) into C2 piston (29). Install clutch hub and piston

seal ring (36) into C1 piston (35).

With a mallet, lightly tap C2 piston (29) into clutch hub (6).

Align notch on C1 piston (35) with lubrication orifice on rotating drive hub. With a mallet, lightly tap C1 piston onto

center of C2 piston (29) and over clutch hub (6).

Install rotating drum (24) over clutch hub (6) and C1/C2 pistons (29 and 35).

Install C2 spring assembly (30). Index spring assembly with drive hub tangs and splines on C2 piston (29). Ensure C2

spring assembly has made contact with bottom of slots in C2 piston. If spring assembly did not reach bottom, remove

spring assembly and reannex in next spline on rotating drum. Repeat this process until C2 spring is in proper position.

Install C2 spring plate (38). Index spring plate with drive hub tangs and splines on C2 piston (29).

WARNING

The rotating clutch piston springs are highly compressed and must be properly released. Failure to follow

this warning may result in personnel injury.

Place rotating clutch on tool base (J37030-3) so that rotating drum is supported by tool tangs. Install tool (J37030-1 and

J35923-2), that includes bearing, washer, and handle. Tighten tool to compress C2 spring assembly (30) and install

retaining ring (37) (View B, page 0083 00-24). Remove tools.

Install seal ring (32) onto balance piston (33).

10.

Install C1 spring assembly (34). Align mark on balance piston (33) with slot on C1 piston (35). Position balance piston

onto the C1 piston.

11.

Install tool (J35923-2) with bearing, washer, and handle. Tighten tool, compressing C1 balance piston (33) and C1

spring assembly (34). Install retaining ring (31) (View A, page 0083 00-24). Remove tools.

12.

If turbine shaft bushing (3) was removed, replace using tool (J37036).

13.

Lubricate with transmission oil and install new O-ring (1) on turbine shaft (2).

NOTE

Butt-joint seal rings require special handling during assembly. Seal rings contain materials that absorb mois-

ture from atmosphere causing them to expand. Check seal ring end clearance before installation to ensure

seal ring has not expanded.

14.

Install each rotating seal ring (4) into ground sleeve bore and measure end gap. Seal ring end gap must be 0.026-0.040 in

(0.65-1.01 mm). Install three rotating seal rings with correct end gap, into rear of turbine shaft (20).

15.

Install turbine shaft (2) and retain with retaining ring (8).

CAUTION

Ensure thrust bearing is assembled with locating lip on either inner or outer thrust bearing race not prevent-

ing race from contacting thrust surface of mating part. Failure to follow this caution leads to thrust bearing

failure and incorrect shim selection to maintain proper part clearance.

16.

Install thrust bearing (7) on rotating clutch hub (6).
