Input Shaft (MAINSHAFT): Disassembly
- For all input shaft measurement specifications, see INPUT SHAFT CLEARANCE SPECIFICATIONS table. Using a feeler gauge, measure 3rd and 4th gear thrust clearances. See Figure. Secure input shaft in soft-jaw vise. Using a dial indicator, measure 3rd and 4th gear lateral movement (oil clearance). See Figure. If clearance exceeds maximum specification, replace gear, needle bearing and/or shaft.
- Remove snap ring from input shaft. Using a bearing splitter or appropriate blocks, support 4th gear, and press input shaft out of rear bearing and 4th gear. Remove needle bearings, spacer and synchronizer ring. Remove snap ring. Supporting 3rd gear, press input shaft out of No. 2 hub sleeve, synchronizer ring, needle bearing and 3rd gear. Remove needle bearing. Press input shaft out of front bearing inner race. See Figure.
