14.2 RELEASING CRANKSHAFT TENSION
When crankshaft parts have been replaced, the shaft can run less smoothly. This can be down to
pretensioning. These tensions have to be released. Act as follows, see Fig. 15:
1. Unscrew the nuts (3) of the bearings (4) a few turns.
2. Next, tighten the bearings one by one from one direction.
3. Check after each bearing whether the crankshaft runs smoothly and has no play.
After repairing the crankshaft, nuts must be checked for looseness regularly.
Mount the cranks in the right way; refer to the parts page for the right order and part
numbers.
