Determining adjusting washer S4 again
Determining adjusting washer S4 again
Special tools and workshop equipment required
t  Depth gauge with at least 5/100 mm measuring accuracy
t  Caliper gauge with at least 5/100 mm measuring accuracy
This adjustment is necessary when replacing the following parts:
t  Bearing shield
t  Inner ring for 1st gear sliding gear needle bearing
t  Synchronizer body 1st and 2nd gear
t  Inner ring for 2nd gear sliding gear needle bearing
t  3rd gear pinion
t  Spacer sleeve
t  4th gear pinion
The adjustment restores the initial load on the taper roller bearing for the secondary shaft.
   
  Note
If replacing the secondary shaft (drive train), refer to Setting Overview → Chapter.

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.
  Note
Use a depth gauge with at least 5/100 mm measuring accuracy
Example:
  V34-2866
Depth “a” of old bearing shield118.40 mm
Depth “a” of new bearing shield118.65 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

  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
  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:
  V34-1510
Length “b” of old inner ring33.35 mm
Length “b” of new inner ring33.40 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.
  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.
  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.
