It is necessary to adjust the output shaft if the following components were replaced:
- Output shaft
- Clutch housing
or
- Tapered roller bearing
Adjustment overview, refer to ADJUSTMENT OVERVIEW .
Requirement:
- Remove any sealant still on the sealing surfaces on the clutch and transmission housings.
Perform the following procedure:
-- Install the small tapered roller bearing outer race with a 0.65 mm thick shim into the clutch housing to the limit stop Installing the Small Outer Race/Tapered Roller Bearing .
-- Install output shaft and tighten the bearing mount nuts to 25 Nm + 90° (1/4) additional turn.
-- Rotate the output shaft 20 to 30 times in one direction.
It must be rotated in one direction so the tapered roller bearing rollers are seated in one direction.
Therefore, it must also be rotated 20 to 30 times in one direction.
Otherwise the measurements will be incorrect.
-- Install dial gauge (3 mm measuring range) and set to "0" with 1 mm preload.
-- Move the output shaft up and down. Read the play on the dial gauge and note it (example: 0.20 mm).
