Crankshaft axial clearance check

- On the right crankcase half of the engine with an appropriate tool measure
the distance from the crank arm 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 contact surface of
the crankshaft washer
- Calculate the axial clearance of the engine 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 external casing surface to the contact surface of the
crankshaft washer.

B: Distance from the crank arm to the outer surface of the casing.
-
- G: Casing gasket thickness:
- X: Crankshaft axial clearance
- A + G - B= X
- Axial clearance of the crankshaft 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.
A
- Refit the right crankcase half as described under the relevant paragraph.
