TORQUE CONVERTER MAINTENANCE (Contd)

TESTING

1. Check torque converter end play:

a. Position torque converter (2) on work bench with pump hub (1) upward.

b. Install converter end play gauge in pump hub (1) of torque converter (2). Hold converter end

play gauge in position and tighten center screw until converter end play gauge is secured and

will not move up or down without pulling hard on gauge.

c. Assemble rod, dial indicator, lug attachment, magnetic clamp, converter end play gauge, and

swivel adapter.

d. Position above items on torque converter (2). Adjust lug attachment until anvil of dial indicator

contacts center screw of converter end play gauge.

e. Set dial indicator to zero. Lift up on center screw as far as possible to obtain end play reading.

f. End play reading of torque converter (2) should read between 0.015 in. (0.38 mm) and

0.037 in. (0.94 mm). If end play reading exceeds limit, replace torque converter (2).

g. Remove dial indicator, magnetic clamp, swivel adapter, lug attachment, rod, and converter end

play gauge from torque converter (2).

2. Check torque converter (2) for leaks:

a. Assemble center body valve with largest stopper, flanged end up, washer just smaller than

stopper, and nut. Tighten nut until it bottoms on shoulder of valve stem.

b. Thread both top nuts and large washer down to flange on stopper.

c. Install center body valve assembly on pump hub (1), hold center body valve, and tighten nut and

washer until stopper begins to extrude slightly at side slots in pump hub (1).

d. Place bracket of converter leak test fixture around torque converter (2) positioning center body

valve in slot of bracket, with top washer behind stop.

e. Thread top nut and washer up to bracket and tighten nut to secure center body valve assembly

down on pump hub (1).

f. Pressurize torque converter (2) to 75 psi (517 kPa), then submerge in water and check for leaks.

Replace torque converter (2) if any air bubbles are observed leaking from torque converter (2).

WARNING

Torque converter leak test fixture is under pressure. Ensure all

air pressure is exhausted from torque converter prior to removing

test fixture to prevent injury to personnel.

g. Release air pressure from torque converter (2).

h. Loosen both nuts and remove converter leak test fixture from torque converter (2).

INSTALLATION

1. Align splines of torque converter (2) to splines of transmission (3).

2. Install torque converter (2) on transmission (3).
