Measure distance between input gear and tapered roller bearing inner race.
Insert dial indicator gauge and zero with a preload of 3 mm. Note reading (example 1.00 mm).

Thickness of dished washer 1.50 mm must be added to reading of = 2.50 mm.

Determining shim

The specified bearing preload is achieved if the bearing preload of 0.18 mm is subtracted from the figure obtained from the measurement (dished washer + reading) of 2.50 mm.

Example

Dished washer + reading	2.50 mm
- Bearing preload	0.18 mm
= Thickness of shim	2.32 mm

Determine shim on basis of table and fit onto drive shaft. Table of shims. Refer to Table of shims for drive pinion and input gear .
Insert axial needle bearing and tighten socket head fastener including dished washer to 250 Nm.

NOTE: Insert axial needle bearing for input shaft before tightening socket head fastener. Installed position. Refer to Removing and installing input gear, Input gear, removing and installing .
