INSPECTION
Clutch and Brake Discs
Dry and inspect them for pitting, burn flaking, wear, glazing,
cracking, charring and chips or metal particles imbedded in lining.
If discs show any of the above conditions, replacement is
required.
Clutch and Brake Plates and Flanges
Dry plates and check for discoloration. If plate surface is smooth
and even color smear is indicated, the plate should be reused. If
severe heat spot discoloration or surface scuffing is indicated, the
plate must be replaced.
1st & 2nd Brake Piston Return Spring Subassembly
Measure height of 1st & 2nd brake piston return spring.
Height of 1st & 2nd brake piston return spring
20.81 mm (0.819 in.)
Evidence of extreme heat or burning in the area of clutch may
have caused springs to take a heat set and would require their
replacement.NOTE:
 If disc lining is exfoliated or discolored, replace all
discs.
 Before assembling new discs, soak them in A/T fluid
for at least two hours.
NOTE:
 Do not apply excessive force when measuring spring
height.
 Perform measurement at several points.

DISASSEMBLY/ASSEMBLY OF SUBASSEMBLY
OIL PUMP
CAUTION:
 Keep component parts in group for each subassembly and avoid mixing them up.
 Clean all parts with cleaning solvent thoroughly and air dry them.
 Use kerosene or automatic transmission fluid as cleaning solvent.
 Do not use wiping cloths or rags to clean or dry parts.
 All oil passages should be blown out and checked to make sure that they are not obstructed.
 Keep face and eyes away from solvent spray while air blowing parts.
 Check mating surface for irregularities and remove them, if any, and clean it again.
 Soak new clutch discs and brake discs in transmission fluid for at least 2 hours before assembly.
 Replace all gaskets and O-rings with new ones.
 Apply automatic transmission fluid to all O-rings.
 When installing seal ring, be careful so that it is not expanded excessively, extruded or caught.
 Replace oil seals that are removed and apply grease to their lips.
 Before installing, be sure to apply automatic transmission fluid to sliding, rolling and thrusting sur-
face of all component part. Also after installation, make sure to check each part for proper opera-
tion.
 Always use torque wrench when tightening bolts.
