Installation of Torque Converter Module and Selective Shim Measurement

NOTE

Torque converter is installed over turbine shaft which rotates inside stator shaft or ground sleeve.

Splines on ground sleeve engage converter stator. Splines on turbine shaft engage converter turbine.

End of turbine shaft is threaded and machined to accept converter retaining bolt and lockup seal ring.

Splines of ground sleeve and turbine shaft must engage with their respective splines in torque converter

module. Tangs on converter-pump hub must engage charging pump's drive gear or PTO oil pump drive

gear hub.

Using a suitable hoist and sling, install torque converter module (19) into torque converter housing (22).

Ensure that torque converter module (19) is properly seated. Rotate PTO gear to engage pump hub with charging pump.

Install converter end play gage tool (J38548) and tighten attaching bolts to 20-25 lb-ft (27-34 Nm). Install two bolts (16)

into flexplate adapter (18). Use two bars at an angle to prevent turbine shaft rotation.

Measure from top of end play gage tool (J38548) to face of turbine shaft and record it as dimension "B". Subtract

dimension "B" from dimension "A" to determine dimension "C" (Note dimension "A" is height of tool J38548, 3.937

inch (100.00 mm).

Use dimension "C" and Table 1, Torque Converter Selective Shims, located at the end of this work package, to deter-

mine proper selective shim part number.

Remove torque converter end play tool (J37548).

Install selective shim (19) with step side down, toward turbine shaft. Install converter center bolt (14) with converter

tightening tool (J38564) and retaining ring (21).

NOTE

Turbine and turbine shaft may rotate while attempting to tighten retaining bolt. Prevent turbine shaft from

turning in same manner as in step number 3.

Tighten converter center bolt (14) to 74-88 lb-ft (100-120 Nm). Remove retaining ring (21) and tool (J38564) and

replace with converter plug (20), O-ring (13), and retaining ring.

Install torque converter shipping bracket. Tighten shipping bracket mounting bolts to 38-45 lb-ft (51-61 Nm).
