(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 of 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 using the thrust plate (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 specification.






- Install the measuring tools to the clutch housing and secure them using a bolt - arrow -.






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

- Loosen the bolts for the clutch housing to transmission housing in a diagonal sequence until the bolts clear the 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 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.

Shim, Selecting

The required bearing tension is reached as follows:

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

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

Example:






- Select the correct adjusting shim thickness according to the 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 using the thrust plate (2050).






Checking the Measurement

The selected adjusting shim is installed.

- Install the measuring tools to the clutch housing and secure them with the bolt - arrow -.






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

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

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