(Finding thickness of "S3" shim)

The output shaft must be adjusted if

• Bearing housing
• crown wheel and pinion
• or output shaft bearings

have been replaced.

See also "Adjustment list",

• ‒ → Place a 0.65 mm shim in the bearing housing and drive the outer race of the small bearing in.
• ‒ Install output shaft and tighten end cover bolts to 40 Nm.

• ‒ → Insert gauge (3 mm range) and zero with 1 mm preload.

• A - Shim 0.65 mm thick.

• ‒ Move shaft up and down and record dial gauge reading (example: 0.30 mm).

Finding thickness of S3 shim

The specified bearing preload is obtained by adding a constant figure (0.20 mm) to the measured reading (0.30 mm) and the shim thickness (0.65 mm) for S3.

• ‒ → Remove shaft and pull outer race of small bearing out

• A - Extractor 37 - 46 mm such as Kukko 21/6.
• B - Support Kukko 22/2

The following shims are available:

Different tolerances make it possible to select the exact thickness of shims required.

• ‒ Drive the small bearing outer race in with the selected shim "S3" (1.15 in example) and install output shaft. Tighten cover bolts to
  40 Nm

→ A = Torque gauge 0 - 600 Ncm

Checking turning torque

This should be 50-150 Ncm for new bearings.

The turning torque on bearings which have been in use should be at least 30 Ncm.

Lubricate bearings beforehand with hypoid gear oil.
