PRECAUTIONSPFP:00001
CautionECS008BM

Do not reuse transaxle oil, once it has been drained.

Check oil level or replace oil with vehicle on level ground.

During removal or installation, keep inside of transaxle clear of dust or dirt.

Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts they are applied to.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.

Be careful not to damage sliding surfaces and mating surfaces.

Adjustment (RS5F51A)ECS008C2
INPUT SHAFT END PLAY

When adjusting input shaft end play, select adjusting shim for
input shaft rear bearing. To select adjusting shim, measure
clearance between transaxle case and input shaft rear bearing.
Refer to MT-102, "
INPUT SHAFT REAR BEARING ADJUSTING
SHIM" .
CAUTION:
Only 1 adjusting shim can be selected.

following procedure to satisfy specification of end play for input
shaft rear bearing.
1. Using depth micrometer and straightedge, measure dimension
"O
1 " between transaxle case end face and mounting face of
adjusting shim.
