SERVICE RELEASE N6

NATURE OF RELEASE: Incorrect assembly of front fork to frame MODELS AFFECTED: All Commando PARTS AFFECTED: Front Fork Assembly DISTRIBUTION: Worldwide EXPLANATION: During assembly of the fork lower lug and stem to the steering head tube of the frame, it is possible for the shoulder of the stem to become lodged against the lower headrace. If this is not realised and the fork should turn on to full lock, the thick cross section of the yoke will lodge against the lock stop on the frame. As the stem is drawn home into the bearings by tightening of the large stem nut, the yoke cannot follow and will either be distorted beyond further use or fractured in the area where the stem joins the yoke.   ACTION: To prevent damage, ensure that the correct lower portion of the stem is central in relation to the lower bearing inner race before the stem nut is tightened.
