d. Assembly.
(1)
Check bottom of fourth clutch piston (1) and note whether
labeled T, S, or M.
(2)
Stack 10 clutch plates (2 and 3) on flat surface of press starting with external steel plate (2) and
alternating with internal friction plate (3).
(3)
Place backplate (4) on clutch plates (2 and 3).
(4)
Press evenly on backplate (4) with 100 psi (689.5 kPa).
(5)
Measure distance from base of clutch pack (5) to machined
surface (6) of backplate (4). This is clutch pack thickness.
(6)
If fourth clutch piston (1) is a T piston, clutch pack thickness
must be 1.361 to 1.387 in. (34.59 to 35.23 mm). If fourth clutch
piston is an S piston, clutch pack thickness must be 1.388 to
1.414 in. (35.26 to 35.92 mm). If fourth clutch piston is an M
piston, clutch pack thickness must be 1.415 to 1.441 in. (35.94
to 36.60 mm). If measurement is incorrect, replace clutch
plates (2 and 3) as needed.
(7)
