WARNING : USE CAUTION WHEN CHECKING COM-
PONENTS WITH COMPRESSED AIR OR PERSONAL
INJURY MAY RESULT.
1. Install the forward and reverse clutch and thrust
needle roller bearing on the transaxle rear cover.
2. Using a dial indicator, measure the reverse clutch
pack clearance while applying and releasing 392
kPa (57 psi) of compressed air.
S Pack clearance: 0.40 1.00 mm (0.0157
0.0394 in.)
S If the stroke is non–standard, inspect the discs,
plates and flange.

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 stroke is non–standard, inspect the discs,
plates and flange.
