Input Shaft Disassembly

1. INSPECT 3RD AND 4TH GEAR THRUST CLEARANCE
Using a feeler gauge, measure the clearance.

Standard clearance:
3rd gear 0.10 - 0.25 mm (0.0039 - 0.0098 in.)
4th gear 0.20 - 0.45 mm (0.0079 - 0.0177 in.)

Maximum clearance:
3rd gear 0.30 mm (0.0118 in.)
4th gear 0.50 mm (0.0197 in.)




2. INSPECT 3RD AND 4TH GEAR RADIAL CLEARANCE
Using dial indicator, measure the radial clearance between the gear and shaft.

Standard clearance: 0.009 - 0.063 mm (0.0004 - 0.0021 in.)
Maximum clearance: 0.070 mm (0.0028 in.)

If the clearance exceeds the maximum, replace the gear, needle roller bearing or shaft.




3. REMOVE SNAP RING
Using 2 screwdrivers and a hammer, tap out the snap ring.




4. REMOVE REAR BEARING, 4TH GEAR, NEEDLE ROLLER BEARINGS, SPACER AND SYNCHRONIZER RING FROM INPUT SHAFT
a. Using SST and a press, remove the 4th gear and rear bearing.
SST 09950-00020
b. Remove the needle roller bearings, spacer and synchronizer ring.




5. REMOVE SNAP RING
Using a snap ring expander, remove the snap ring.




6. REMOVE NO.2 HUB SLEEVE ASSEMBLY, 3RD GEAR SYNCHRONIZER RING AND NEEDLE ROLLER BEARINGS
Using SST and a press, remove the No.2 hub sleeve, 3rd gear, synchronizer ring and needle roller bearings.
SST 09950-00020

NOTE: Be careful not to mistake the 3rd gear synchronizer ring for the 4th gear synchronizer ring.




7. REMOVE NO.2 HUB SLEEVE, SHIFTING KEYS AND SPRINGS FROM NO.2 CLUTCH HUB
Using a screwdriver, remove the 3 shifting keys and 2 springs from the No.2 clutch hub.
