16. Install the forward and reverse clutch and thrust
needle roller bearing on the transaxle rear cover.
17. Using a dial indicator and measuring terminal
DW240–120, measure the forward clutch pack
clearance while applying and releasing 392 kpa (57
psi) of compressed air.
S The forward and reverse clutch will come out as
you apply the compressed air. Therefore, while
the checking is being done, press on the input
shaft of the forward and reverse clutch using
stamping machine or alike so that the pressure
is not applied on the forward and reverse clutch.
S Pack clearance: 1.1–1.5 mm (0.043
0.059 in.)
If the pack clearance is less than the limit of
pack clearance, parts may have been as-
sembled incorrectly, so check and reassemble
again.
If the pack clearance is non–standard, select
another flange.
There are 4 flanges in different thickness.
