Inspecting the crankshaft components

Crankshaft axial clearance check

•
The shaft axial clearance on the crank-
case should be checked with a dial
gauge mounted on the specific dial
gauge support.
•
The clearance should be between 0.1
- 0.26 mm (0.0039 - 0.0102 in).
•
If the clearance is beyond tolerance,
check the reference surfaces.

Removal

•
Mark the position of the original semi-bushings on the crankcase.
•
To reduce the installation force neces-
sary, score an incision approximately
0.5 mm (0.02 in) deep (without cutting
into the steel shell) in each semi-bush-
ing in the area indicated in the figure.
•
Remove the bushings with the crank-
case cold, using a press and the spe-
cific tool and pushing inward from the
outside of the crankcase.
