Stack eight clutch plates (9 and 10) on
backplate (8), starting with friction

plate (10).
Place third clutch piston (4) on top of
clutch plates (9 and 10).
Press evenly on third clutch piston (4)
with 980 to 1020 lb load (4359 to
4536.9 N).
Measure distance from base of clutch
pack (11) to thrust pad (12).
Clutch pack thickness must be 3.010 to
3.042 in. (76.45 to 77.26 mm). Replace
clutch plates (9 and 10) as needed to
ensure proper clutch pack thickness.
Measure thickness of one tang (13) on
each of four steel plates (10).
(a)
If steel plate measures 0.116 to
0.123 in. (2.95 to 3.12 mm) steel
plate is thick.
(b)
If steel plate measures 0.099 to
0.106 in.(2.51 to 2.69 mm) steel
plate is thin.
Repeat steps (8) through (13) to
recheck clutch pack thickness.
Remove clutch pack (11) from press.
Apply lubricating oil to inner seal
ring (14) and outer seal ring (15).
Install inner seal ring (14) and seal
