M/T Housing Mainshaft Thrust Clearance Adjustment
Attach the catch adapter (A), base adapter (B), and base collar (C) to the mainshaft as follows:
Back-out the catch adapter bolt (D) and loosen the two hex bolts (E).
Fit the holder over the mainshaft so its lip is toward the transmission.
Align the catch adapter lip around the groove at the inside of the mainshaft splines, then tighten the hex bolts.
Fully seat the mainshaft by tapping its end with a plastic hammer.
Thread the catch adapter bolt in until it just contacts the wide surface of the base adapter.
