Input Shaft

INPUT SHAFT

COMPONENTS:

DISASSEMBLY





1. REMOVE FRONT CLUTCH CLUTCH DISC
(a) Using a screwdriver, remove the snap ring.
(b) Remove the flange, 4 discs and 4 plates from the input shaft.





2. REMOVE FORWARD CLUTCH RETURN SPRING SUB-ASSEMBLY
(a) Using SST on the clutch balancer, compress the return spring with a press.
SST 09320-89010

NOTICE: Do not compress the return spring excessively.

(b) Using a snap ring expander, remove the snap ring.





(c) Remove the clutch balancer and piston return spring.





3. REMOVE FORWARD CLUTCH PISTON
(a) Place the input shaft onto the oil pump.
(b) Holding the forward clutch piston by hand, apply compressed air (392 kPa, 4.0 kgf/cm2, 57 psi) to the oil pump to remove the forward clutch piston.

HINT: When the piston can not be removed due to being slanted, either blow the air again with the protruding side pushed or remove the piston using needle-nose pliers with their tips wrapped in protective tape.





4. REMOVE FORWARD CLUTCH PISTON O-RING
(a) Using a screwdriver, remove the clutch piston O-ring from the forward clutch piston.





5. REMOVE INPUT SHAFT OIL SEAL RING
(a) Using a screwdriver, remove the input shaft oil seal ring from the input shaft.

INSPECTION





1. INSPECT FRONT CLUTCH CLUTCH DISC
(a) Check whether the sliding surface of the disc, plate and flange are worn or burnt. If necessary, replace them.

NOTICE:
^ If the lining of the disc is peeling off or discolored, or even if a part of the printed number is defaced, replace all the discs.
^ Before assembling new discs, soak them in ATF for at least 15 minutes.





2. INSPECT FORWARD CLUTCH RETURN SPRING SUB-ASSEMBLY
(a) Using vernier calipers, measure the free length of the spring together with the spring seat.
Standard free length: 21.69 mm (0.8540 in.)

REASSEMBLY





1. INSTALL INPUT SHAFT OIL SEAL RING
(a) Coat a new input shaft oil seal ring with ATF, and install it into the input shaft.





2. INSTALL FORWARD CLUTCH PISTON O-RING
(a) Coat a new clutch piston O-ring with ATF, and install it into the forward clutch piston.





3. INSTALL FORWARD CLUTCH PISTON
(a) Install the forward clutch piston into the input shaft.

NOTICE: Do not damage the O-ring.





4. INSTALL FORWARD CLUTCH RETURN SPRING SUB-ASSEMBLY
(a) Install the return spring and clutch balancer into the input shaft.





(b) Using SST, a press and snap ring pliers, install the snap ring onto the input shaft.
SST 09320-89010





5. INSTALL FRONT CLUTCH CLUTCH DISC
(a) Install the 4 plates, 4 discs and flange.
(b) Using a screwdriver, install the snap ring into the input shaft.





6. INSPECT PACK CLEARANCE OF FORWARD CLUTCH
(a) Using a dial indicator, measure the pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).
Pack clearance: 1.406 to 1.806 mm (0.05535 to 0.07110 in.)

NOTICE: If the clearance is outside the specifications, select a new brake flange.

HINT: There are 4 different flange thicknesses.

Flange thickness:
