(Selecting the correct adjusting shim for the output shaft)

It is necessary to adjust the output shaft if the following components were replaced:

• Transmission housing

• Clutch housing

• Output Shaft, 1st to 4th gears or

• Output shaft tapered roller bearing

Adjustment overview, refer to => [ Adjustment Overview ] Adjustment Overview

Requirements:

• Remove any sealant still on the sealing surfaces on the clutch and transmission housings.

• Install the output shaft that is going to be measured.

- Install the tapered roller bearing outer race in the transmission housing with a 1.70 mm adjustment shim. Support the transmission housing directly under the bearing mount with a (2050).






- Install the output shaft for 1st through 4th gears into the clutch housing.

- Install the transmission housing and tighten the bolts - A and B - diagonally to the tightening specification.






- Position the measuring tools on the clutch housing and secure them with a bolt - arrow -.






- Set the dial gauge (3 mm range) with 1 mm preload to "0".

- Loosen securing bolts for clutch housing/transmission housing in diagonal sequence until the bolts clear transmission housing and output shaft.

- Read the measured value on the dial gauge and make a note of it (example: to 0.14 mm).

• The measured value will not be displayed when loosening the bolts that connect the clutch housing to the transmission housing.

• Install the either the 1.95 mm adjusting shim or the 2.20 mm adjusting shim for the measuring.

• For the correct adjusting shim, refer to the Parts Catalog.

Determining Shim Thickness

The required bearing tension is reached as follows:

The specified bearing preload is reached when determined measured value (0.14 mm) is subtracted from inserted adjustment shim (1.70 mm).

A constant figure of (0.40 mm) is added to the reading.

Example:






- Select the correct shim thickness according to the table. Refer to => [ Adjustment Shim Table ].

- Remove the transmission housing and remove the tapered roller bearing outer race from the transmission housing.






A Counter support , for example, Kukko support (22/2)
B Internal puller 46 to 58 mm , for example, Kukko extractor 46-58 mm (21/7)

- Remove the adjusting shim (1.70 mm) from the transmission housing.

Adjustment Shim Table






Tolerance variations make it possible to find the exact shim thickness required.

- For the shim part number, refer to the Parts Catalog.

- Install the outer race/tapered roller bearing with the selected adjusting shim (in the example: 1.75 mm). Support the transmission housing directly under the bearing mount with a (2050).






Checking Measurement

• The selected adjusting shim is installed.

- Position the measuring tools on the clutch housing and secure them with a bolt - arrow -.






- Set the dial gauge (3 mm range) with 1 mm preload to "0".

- Loosen securing bolts for clutch housing/transmission housing in diagonal sequence until bolts clear transmission housing and output shaft.

- For correctly selected adjustment shim, dial gauge must now display a value of 0.15 mm to 0.25 mm.
