Measuring input shaft end play before disassembly
will usually indicate when a #4 thrust plate change
is required, (except when major parts are replaced).
The #4 thrust plate is located behind the overdrive
clutch hub. Attach a dial indicator to transaxle bell housing
with its plunger seated against end of input shaft
(Fig. 14). Move input shaft in and out to obtain end play
reading. End play specifications are .13 to .64 mm
(.005 to .025 inch). Record indicator reading for reference when reas-
sembling the transaxle.
