CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place. Metal
tools will cut, shave, or score the seals.
(5) Install and position clutch piston springs as
shown in Figure 72.

as follows (Fig. 73):
• On 46RH, 3-disc clutch, clearance between waved
spring and pressure plate should 1.78 - 3.28 mm
(0.070 - 0.129 in.).
• On 47RH, 4-disc clutch, clearance between waved
spring and pressure plate should be 2.08 to 3.83 mm
(0.082 to 0.151 in.).
(12) If clutch pack clearance is incorrect, snap ring
may have to be changed. If this does not correct prob­
lem, steel plates, discs, and pressure plate may also
have to be changed.

Clean the clutch components with solvent and dry
them with compressed air.
Check condition of the input shaft seal rings. It is
not necessary to remove or replace rings unless they
are broken, cracked, or no longer securely hooked to­
gether.
Inspect the input shaft splines and machined sur­
faces. Very minor nicks or scratches can be smoothed
off with 380-400 grit paper. Replace the shaft if the
splines are damaged, or any of the machined surfaces
are severely scored.
Replace the clutch discs if warped, worn, scored,
burned/charred, the lugs are damaged, or if the fac­
ing is flaking off.
Replace the steel plates and the pressure plate if
heavily scored, warped, or broken. Be sure the driv­
ing lugs on the discs and plates are also in good con­
dition. The lugs must not be bent, cracked or
damaged in any way.
Replace the piston spring and wave spring if either
part is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The
steel plates should slide freely in the slots. Replace
