FIG.4 FRONT FORK
COMPONENT
Steering adjustment
PROCEDURE:
●
When the front fork slightly sways or when the direction handle swings during braking
Check whether the pressure of the front tire is the recommended air pressure at room temperature: 250±10kPa. If it is lower than
the recommended air pressure, the front tire pressure should be inflated to 350 kPa first, and then deflated to 250±10 kPa. Let us
check if the running-up test is released. If not, set the front wheel and turn to inspect the tire tread, if it is worn or deformed, the
front tire needs to be replaced. If not, you should continue to the following operation.
●
Check steering device
Set up the front wheel and shake the lower part of the fork by hand to check if the steering shaft is loose or the left and right
rotation is flexible.
Adjust the adjusting nut:
Remove the trim nut(1) with a spanner, remove the gasket(2), and remove the bolt(3) with the hexagonal tool. The direction of
the upper connection assembly wrapped with a clean cloth and then placed to prevent scratches. Remove the lock washer(4);
remove the top adjusting nut(5) with a special four-jaw shank or hook wrench and remove the pad(6). If the steering resistance is
too large, rotate the bottom adjusting nut(5) counterclockwise. If the brake slightly sways or swings, then rotate it clockwise. The
torque is approximately 14N.m. It is suitable when holding the front wheel to rotate freely and there is not getting stuck.
When reassembling, the top adjusting nut only needs to be screwed to align with the bottom nut groove, so as not to over-tighten
to avoid excessive deformation of the rubber pad(6); the torque requirement of the decorative nut(1) is 100 N.m.
●
Steering bearing
If the above operation still can not rule out excessive steering resistance or stuck as follows:
Remove the adjusting nut(5), remove the upper dust cover(7), shaft ring(8), and conjoined steel ball(9), remove the directional
column & front shock absorber & front wheel assembly, check the shaft ring and the conjoined steel ball for abnormal wear or rust
. At the same time, check whether the seat ring(10) in the front frame of the motorcycle frame is abnormally worn or rusted. If you
need to, you need to purchase replacement parts on Zontes official website. Newly-applied conjoined steel balls need to be evenly
greased, paying attention to the amount of grease.
CAUTION:
●
The vehicle should be fixed and then operated. During the dismantling process, the material should be protected to prevent
scratches.
●
If the steering adjustment is too tight, the steering force will be greater. If it is too loose, the front of the vehicle will be slightly
shaken when braking, and the driver needs to adjust according to the actual needs of the driver.
