It is necessary to readjust the output shaft when the following components are replaced:

Transmission housing
Clutch housing
Output shaft for 1st-4th gear

Tapered roller bearing

Adjustment overview. Refer to Adjustment overview

Requirements

Sealing surfaces of clutch and transmission housings must be free of sealant.
When taking measurements, install only the shaft to be measured.

Install transmission housing and tighten bolts -A- and -B- diagonally to correct torque.

Fig 5: Identifying Measuring Tools, Secure With Bolt To Clutch Housing

Install measuring tools and secure with bolt (arrow) to clutch housing.
Set dial gauge (3 mm measuring range) to zero with 1 mm preload.
Loosen clutch housing/transmission housing securing bolts diagonally until output shaft is free to move in transmission housing.
Read play on gauge and note reading (example: 0.14 mm)

NOTE: If the dial gauge indicates no value when the clutch housing/transmission housing securing bolts are loosened, install shim 1.95 mm (Part No. 084 409 383 AS) or, if necessary, shim 2.20 mm (Part No. 084 409 383 BD).

Determining thickness of shim

The specified bearing pretension will be attained by subtracting the measured value (0.14 mm) from the inserted shim (1.70 mm) and adding a constant for pressing (0.20 mm).

Example:

Inserted shim	1.70 mm
- Measured value	0.14 mm
+ Preloading (constant)	0.20 mm
Shim thickness	1.76 mm

Determine thickness of shim from table. Refer to Shim table .

Remove transmission housing and pull tapered roller bearing outer race out of transmission housing.

A - Counter support, e.g. Kukko 22/2

B - Internal puller 46 to 58 mm, e.g. Kukko 21/7

Remove inserted shim from clutch housing.

Press in tapered roller bearing outer race together with determined shim (in example 1.75 mm) while supporting transmission housing with thrust piece 2050 directly under bearing support.

Perform check measurement

Determined shim installed.

Fig 8: Identifying Measuring Tools, Secure With Bolt To Clutch Housing

Install measuring tools and secure with bolt (arrow) to transmission housing.
Set dial gauge (3 mm measuring range) to zero with 1 mm preload.
Loosen clutch housing/transmission housing securing bolts diagonally until output shaft is free to move in transmission housing.

If the correct shim has been selected, the dial gauge will indicate a value of 0.15 mm to 0.25 mm.
