Input Shaft Overview

Input Shaft Overview

• When installing new gears or a new input shaft, refer to the => [ Transmission-Engine Allocation ] Transmission-Engine Allocation and the Parts Catalog.

• The input shaft must be adjusted because the position of the tapered roller bearing is affected when parts are replaced. Pay attention to the adjustment overview. Refer to => [ Adjustment Overview ] Adjustment Overview.

• Replace both tapered roller bearings together.

• Wearing safety gloves, heat the bearing inner race/tapered roller bearing, the gears and the synchronizer hubs to approximately 100 °C (212 °F) using the inductive heat unit (VAS 6414) or equivalent before installing them.
