Steering Head Components / Rigid Fork Model cont.

Slide the upper cap up the handlebar stem, and out of the way. Remove the lower cap. Removal of these caps reveals
the large, 40mm nuts that secure the steering head assembly from the top and bottom. It is not necessary to remove the
large top nut. The steering head is held in place by two bottom 40mm nuts. One is intended to provide adjustment, and
is closest to the steering head, and the one directly beneath it is a jamb nut to ensure they do not come loose in
operation.
With these bottom nuts removed, remove the lower bearing and spacer. This will enable the entire down-tube, with the
upper bearing, to be slid out the top of the steering head. It will be necessary to fold the front steering handle to the
down position (Fig. 11) to allow enough slack in the control cables for the steering stem to be lifted from the steering
head.
Take the opportunity to thoroughly clean all parts with cleaning solvent, and inspect bearings. If they feel worn or do not
turn freely, replace them. Re-grease the bearings and carefully re-assemble.
