11. Snap ring
Install the snap ring with a screw driver. Be sure the end
gap of the snap ring is not aligned with the cutout por tion of
the forward clutch drum.
Check piston stroke of forward clutch (C–1)
Using a dial indicator, measure the forward clutch piston
stroke by applying and releasing the compressed air (4–
8kg/cm
2, 57–114psi or 392–785kPa) as shown.
If the Pack clearance is not within specification, select
another flange, and recheck the piston stroke.
There are eight flanges.
