Countershaft clearance check

- On the right crankcase half of the engine with an appropriate tool measure the
distance from countershaft bearing seat to the outer surface of the crankcase
(B).
- On the left crankcase half of the engine with an appropriate tool measure the
distance from the outer surface of the casing to the internal ring of the ball
bearing.
- Calculate the axial clearance of the countershaft according to the following
formula, paying attention to the thickness of the crankcase gasket.
B
Crankcase gasket thickness: 0.4 mm (0.02 in.).
- A: distance from the outside surface of the crankcase to the internal ring of
the ball bearing.
H11621
- B: distance from the bearing seat to the outside surface of the crankcase.
- G: Crankcase gasket thickness
- X: Countershaft axial clearance
A + G - B= X
- Axial clearance of the countershaft must be equal to 0.1 ... 0.3 mm (0.0039
... 0.0118 in.).
- If this condition is not satisfied, use a spacer washer of appropriate thickness
to obtain the correct clearance.
- Refit the right crankcase half as described under the relevant paragraph.
