Input Shaft: Disassembly
- Using a feeler gauge, measure 3rd gear and 4th gear thrust clearances. See Fig 1. See INPUT SHAFT CLEARANCE SPECIFICATIONS table. Secure input shaft in soft-jaw vise. Using a dial indicator, measure 3rd gear and 4th gear radial clearance. See Fig 2. If any clearance exceeds service limit, replace gear, needle roller bearing and/or shaft.
- Using 2 screwdrivers and a hammer, tap out input shaft snap ring. Using Bearing Remover (09950-00020) and a press, remove rear ball bearing. Remove needle roller bearing, spacer and synchronizer ring. See Figure.
- Using 2 screwdrivers and a hammer, tap out snap ring. Using bearing remover and a press, remove No. 2 hub sleeve, No. 2 clutch hub assembly, 3rd gear and synchronizer ring. See Figure.
