What torque is specified for the converter housing bolts during the Type A preload adjustment?

14 N·m (1.4 kg-m, 10 ft-lb), tightened alternately with four spacers positioned evenly around the transmission case.

What special tools are shown for the side bearing preload procedure?

Tool J33200 (measured around with a feeler gauge) and adapter J33200-83, placed with the left side bearing inner race in the transmission case.

How is the correct shim thickness determined?

Rotate the final drive assembly a few times to ensure seating, then use a feeler gauge to measure the widest gap G around the Tool, and select a shim of proper thickness using S.D.S. as a guide (available shims: refer to S.D.S.).

What is the final step after installing the selected shim?

Install the shim on the bearing retainer with the bearing inner race, then lubricate the O-ring and install it on the bearing retainer.

This is page AT-41 of an automatic transaxle service manual section covering differential side bearing preload adjustment. It explains that whenever the transmission case, bearing retainer, tapered roller bearing, differential case, or converter housing is replaced, the final drive preload must be adjusted by selecting shims of appropriate thickness, and that two adjusting procedures exist. The page details the "Type A" procedure: remove the left side bearing inner race and shims from the bearing retainer using a drift and puller (illustration SAT990); place special tool J33200-83 with the differential/final drive parts in the transmission case (illustration SAT950), noting a gasket must be installed on the transmission case; position four spacers evenly around the case, install the converter housing, and tighten bolts alternately to 14 N·m (1.4 kg-m, 10 ft-lb); rotate the final drive assembly for seating and measure the widest gap G around the tool (J33200) with a feeler gauge; select a shim of proper thickness using S.D.S. specifications; remove the bearing retainer, install the selected shim and bearing inner race, and lubricate and install the O-ring on the bearing retainer. Readers learn the tools, torque value, and step-by-step shim-selection method for setting differential side bearing preload.

Frequently asked questions

When does the differential side bearing preload need to be adjusted?: If the transmission case, bearing retainer, tapered roller bearing, differential case, or converter housing is replaced, the final drive should be adjusted. Preload is adjusted by selecting shims of appropriate thickness.
What torque is specified for the converter housing bolts during the Type A preload adjustment?: 14 N·m (1.4 kg-m, 10 ft-lb), tightened alternately with four spacers positioned evenly around the transmission case.
What special tools are shown for the side bearing preload procedure?: Tool J33200 (measured around with a feeler gauge) and adapter J33200-83, placed with the left side bearing inner race in the transmission case.
How is the correct shim thickness determined?: Rotate the final drive assembly a few times to ensure seating, then use a feeler gauge to measure the widest gap G around the Tool, and select a shim of proper thickness using S.D.S. as a guide (available shims: refer to S.D.S.).
What is the final step after installing the selected shim?: Install the shim on the bearing retainer with the bearing inner race, then lubricate the O-ring and install it on the bearing retainer.
