Checking contact surface and brass sleeve of shaft for wear





- Check contact surfaces of brass sleeve - arrow 2 - at inside of shaft and contact surface at outer circumference - arrow 1 - for wear.

Contact surfaces must not be heavily scored and/or show blue discoloration.

In case of deep grooves and/or blue color:

- Replace shaft.

If no blue discoloration and only small grooves are detected, proceed as follows:

- Sandpaper (600 grit, oiled) contact surface 1 to 2 times.

- Carefully wipe off with a clean rag and check contact surface.

Contact surfaces must now be like new.

If scores cannot be removed in this manner:

- Replace shaft.

Checking contact surfaces of shaft planetary carrier "III" for wear





- Check contact surfaces - arrows - of shaft for wear.

Contact surfaces must not be heavily scored and/or show blue discoloration.

In case of deep grooves and/or blue color:

- Replace planetary drive.

If no blue discoloration and only small grooves are detected, proceed as follows:

- Sandpaper (600 grit, oiled) contact surface 1 to 2 times.

- Carefully wipe off with a clean rag and check contact surface.

Contact surfaces must now be like new.

If scores cannot be removed in this manner:

- Replace planetary drive.

Checking axial and radial play of planetary gears





- Check axial play of planetary gears - arrow A -.

Axial play wear limit: 0.4 mm.

- Check planetary gears for radial play - arrow B -.

Planetary gears must not show radial play.

- Check planetary gear axles.

Axle peening must be intact.

Area around axles must not be blue.

- Replace planetary carrier "III" if necessary.
