End Play Adjustment
Example #1: countershaft end play adjustment
Specified end play: 0,0
1
0 mm to 0,0
8
0 mm
Measured end play: 0,47 mm
As the measured value is greater than 0,0
8
0 mm (maximum specified), calculate:
0,470 – 0,0
8
0 = 0,3
9
0 mm (R1)
0,470 – 0,0
1
0 = 0,4
6
0 mm (R2)
The shim pack thickness must be within 0,3
9
0 mm and 0,4
6
0 mm.
Example #2: mainshaft end play adjustment
Specified end play: 0,010 mm to 0,0
6
0 mm
Measured end play: 0,15 mm
As the measured value is greater than 0,0
6
0 mm (maximum specified), calculate:
0,150 – 0,0
6
0 = 0,0
9
0 mm (R1)
0,150 – 0,010 = 0,140 mm (R2)
The shim pack thickness must be within 0,0
9
0 mm and 0,140 mm.
Example #3: countershaft end play adjustment
Specified end play: 0,0
1
0 mm to 0,0
8
0 mm
Measured end play: 0,0
0
5 mm
In this case, it is not possible to calculate the shim thickness, since the clearance is
already less than the minimum specified. This measured value is not a valid value.
So, it is necessary to redo the measurement, verifying before if all existing shims were
actually removed, if the bearing cup is perfectly seated on the bearing bore and free
of any kind of dirt, and if the shaft is seated properly on the bearing, by rotating the
shaft in both directions clockwise and counterclockwise.
27. Shift the 1st gear and remove the retaining roll
pin from the shift lug, by pushing it forward into
the housing.
NOTE: Use a 6 mm diameter pin punch.
28. Remove the retaining capscrews from the
intermediate housing.
29. Remove the intermediate housing.
NOTE: If necessary, carefully hit the
housing’s capscrews area with a plastic
hammer to detach the housing.
