Overdrive Unit Endplay Check

Overdrive unit endplay should be checked prior to removing internal parts. If endplay is not within specifications, check or worn or improperly assembled parts during disassembly. Check endplay as follows:

d. Maintain approximately 3 lbs. of lifting force while setting dial indicator to zero.






e. Increase lifting force to approximately 20 lbs, then measure endplay. Endplay should be 0.004-0.027 inch. Refer to chart for selection of proper washer.
