Transmission Maintenance Instructions (Cont)
Some clutch assemblies contain paper
friction plates. When servicing clutch
assembly, replace all paper friction plates
with graphite friction plates. Paper friction
plates and graphite friction plates cannot
be intermixed within the same clutch
assembly. Refer to TM 9-2320-279-24P for
identification of parts.
Stack 13 clutch plates (6 and 7) on flat
surface of press, starting with steel
plate (6) and alternating with friction
Place second clutch piston (1) on top of
clutch plates (6 and 7).
Press evenly on second clutch piston (1)
with 980 to 1020 lb load (4359 to
Measure distance from base of clutch
pack (8) to top of thrust pad (9).
Clutch pack thickness must be 3.136 to
3.168 in. (79.66 to 80.48 mm). Replace
clutch plates (6 and 7) as needed to
ensure proper clutch pack thickness.
Measure thickness of one tang (10) on
each of seven steel plates (6).
If steel plate measures 0.116 to
0.123 in. (2.95 to 3.12 mm), steel
plate is thick.
If steel plate measures 0.099 to
0.106 in. (2.51 to 2.69 mm), steel
plate is thin.
Repeat steps (5) through (9) to recheck
clutch pack thickness.
Remove clutch pack (8) from press.
Apply lubricating oil to inner seal
ring (11) and outer seal ring (12) and
install inner seal ring and outer seal
ring on second clutch piston (1) with
lips facing down.
