Installation of Torque Converter Housing Module
1.
Position transmission with input end up. Install a new converter housing gasket (24) on main housing (23).
2.
Lower torque converter housing (21) onto main housing (23) while rotating PTO drive gear to align gear teeth with
charging pump.
3.
Install seven bolts (22) into inside of torque converter housing (21). Use of mechanical fingers or similar tool may be
required to insert and start bolts.
4.
Install remaining 18 bolts (22). Tighten all bolts to 55-65 lb-ft (74-88 Nm)
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.
1.
Using a suitable hoist and sling, install torque converter module (18) into torque converter housing (21).
2.
Ensure that torque converter module (18) is properly seated. Rotate PTO gear to engage pump hub with charging pump.
3.
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 (17). Use two bars at an angle to prevent turbine shaft rotation.
4.
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).
