A - Determining the adjusting washer when replacing the bearing shield –  Thoroughly clean the housing and the bearing pedestal on the previous and new bearing bracket.

–  Measure the difference in depth -a- between new and old bearing shield. Diagram not available  Note Use a depth gauge with at least 5/100 mm measuring accuracy Example:

Depth “a” of old bearing shield	118.40 mm
Depth “a” of new bearing shield	118.65 mm
Difference	= 0.25 mm

–  Fit a thicker adjusting washer S4, if the new bearing shield is deeper. –  Fit a thinner adjusting washer S4, if the old bearing shield is deeper. Example:

Previous adjusting washer“S4”	0.95 mm
Difference	+ 0.25 mm
New adjusting washer “S4”	= 1.20 mm

Diagram not available  Note Assign the adjusting washers via → Electronic Catalogue of Original Parts. If the measured washer thickness is greater than the one listed in the → Electronic catalogue of original parts, 2 washers corresponding to the measured value may be fitted. B - Determining the adjusting washer when replacing the needle bearing for 1st gear Diagram not available  Note Use a caliper gauge with at least 5/100 mm measuring accuracy

–  Measure length -b- on the old and new inner rings of the needle bearing. Example:

Length “b” of old inner ring	33.35 mm
Length “b” of new inner ring	33.40 mm
Difference	= 0.05 mm

–  Fit a thicker adjusting washer S4, if the old inner ring is longer. –  Fit a thinner adjusting washer S4, if the old inner ring is shorter. Diagram not available  Note Assign the adjusting washers via → Electronic Catalogue of Original Parts. If the measured washer thickness is greater than the one listed in the → Electronic catalogue of original parts, 2 washers corresponding to the measured value may be fitted. C- Determine the adjusting washer if replacing Pos. 4...8 → Anchor –  For size “c”...“g” ( → Anchor) determine the difference in size between the old and new in the same way, and determine adjusting washer S4. Diagram not available  Note Assign the adjusting washers via → Electronic Catalogue of Original Parts. If the measured washer thickness is greater than the one listed in the → Electronic catalogue of original parts, 2 washers corresponding to the measured value may be fitted.
