7.7.5

Installing the ball bearings

CAUTION!
Incorrect reassembly can damage the bearings and cause the steering wheels to fall out!
The single-row angular ball bearing rings are not identical on both sides! There is only one correct
way to insert them!
· The bearings must always be assembled so that the narrow borders of the ball bearings are
facing each other (inside)!
· The steering head bolts and nuts must always be pressing against the wide (outside) border of
the ball bearings! Otherwise, the bearings will be pressed apart and damaged by the bolts!
The illustrations show the wide border of the ball bearing on the
outside of the ball race (A) and the narrow ball bearing edge on
the inside (B).
After assembly, the steering wheels should rotate freely but the
bearings should have no play.
