IMPORTANT ASSEMBLY INFORMATION!
The illustrations show the wide edge on the outside of the ball
race (A) and the narrow edge on the inside (B).
The bearings must always be installed in such a way that the
narrow edges are facing each other (inside). The steering head
bolt and the nut must always press against the wide outside
edges. The bearings would otherwise be pressed apart by the
bolt pressure.
The steering wheels should be able to rotate freely after
assembly, but there must not be any clearance on the bearings.
·
Tighten the nut primarily to 20 Nm +/- 2 Nm.
·
Slacken the nut slightly.
·
Re-tighten to 15 Nm +/- 1.5 Nm.
