Maximum inside diameter: 21.57 mm (0.8492 in.) If the inside diameter is greater than the maximum, re- place the stator shaft. OIL PUMP ASSEMBLY 1. INSTALL FRONT OIL SEAL Using SST and a hammer, install a new oil seal. The seal end should be flush with the outer edge of the pump body. SST 09350-32014 (09351-32140) AX031-02
AUTOMATIC TRANSAXLE OIL PUMP - AX-37 2. INSTALL DRIVEN GEAR AND DRIVE GEAR Make sure the top of the gears are facing upward. 3. INSTALL STATOR SHAFT TO PUMP BODY (a) Align the stator shaft with each bolt hole. (b) Torque the 11 bolts. Torque: 10 N·m (100 kgf·cm, 7 ft·lbf) 4. INSTALL THRUST WASHER (a) Coat the thrust washer with petroleum jelly. (b) Align the tab of the washer with the hollow of the pump body. 5. INSTALL OIL SEAL RINGS Install the 2 oil seal rings to the stator shaft back side. NOTICE: Do not spread the ring ends more than necessary. HINT: After installing the oil seal rings, check that they move smoothly. 6. CHECK PUMP DRIVE GEAR ROTATION Turn the drive gear with 2 screwdrivers and make sure it rotates smoothly. NOTICE: Be careful not to damage the oil seal lip.
AUTOMATIC TRANSAXLE DIRECT CLUTCH - AX-38 DIRECT CLUTCH COMPONENTS DIRECT CLUTCH DISASSEMBLY 1. CHECK PISTON STROKE OF DIRECT CLUTCH (a) Install the direct clutch on the oil pump. (b) Install a dial indicator and measuring terminal (SST) to- gether, measure the direct clutch piston stroke while ap- plying and releasing compressed air (392-785 kPa, 4-8 kg/cm 2 , 57-114 psi). SST 09350-32014 (09351-32190) Piston stroke: 0.91-1.35 mm (0.0358-0.0531 in.) If the piston stroke is greater than the maximum, inspect each component. AX032-02 AX033-05
AUTOMATIC TRANSAXLE DIRECT CLUTCH - AX-39 2. REMOVE SNAP RING FROM CLUTCH DRUM 3. REMOVE FLANGE, DISCS AND PLATES 4. REMOVE PISTON RETURN SPRING (a) Place SST on the spring retainer and compress the springs with a press. SST 09350-32014 (09351-32070) (b) Remove the snap ring with snap ring pliers. (c) Remove the piston return spring. 5. REMOVE CLUTCH PISTON (a) Install the direct clutch onto the oil pump. (b) Apply compressed air to the oil pump to remove the piston (if the piston does not come out completely, use needle- nose pliers to remove it). (c) Remove the direct clutch from the oil pump. (d) Remove the 2 O-rings from the piston.
AUTOMATIC TRANSAXLE DIRECT CLUTCH - AX-40 DIRECT CLUTCH INSPECTION 1. INSPECT CLUTCH PISTON (a) Check that the check ball is free by shaking the piston. (b) Check that the valve does not leak by applying low-pres- sure compressed air. 2. INSPECT DISCS, PLATES AND FLANGE Check if the sliding surfaces of the discs, plates and flange are worn or burnt. If necessary, replace them. HINT: L If the lining of the disc is peeling off or discolored, or even if a part of the printed numbers are defaced, re- place all discs. L Before assembling new discs, soak them in ATF for at least 15 minutes. 3. CHECK DIRECT CLUTCH BUSHING Using a dial indicator, measure the inside diameter of the direct clutch bushing.
