b. Keep the front wheel suspended, shake the front wheel
assembly in multiple directions, to confirm whether the front
fork assembly is axially strung or loosened in the radial
direction.
2. Adjust the steering mechanism
If the steering is not flexible or loose, the axial bearing
clearance should be adjusted.
a. Refer to this manual, Front Fork Assembly, to remove
the front panel. Remove and remove the faucet lock. Remove
the two bolts of the upper plate.
Remove the nut (1) counterclockwise with the 30# sleeve and
remove the spacer (2).
b. Other components are omitted here for ease of
explanation. Move the washer (3) upwards and loosen the
adjusting nut (4A) with a 38-42 hook wrench within 6mm
(0.24 in); Finally loosen the adjusting nut (4b). Pull out the
directional handle and uplink plate assembly. If it is difficult
to pull out, you can use a flat screwdriver to pry the upper
plate slotted slightly and then pull it out at the same time.
Move the orientation handle and the uplink plate assembly
away and place it.
c. Screw the adjusting nut (4b) clockwise to 50N.m (5.1
kgf.m, 37 lbf.ft), turn the front of the car to feel tight to
normal, loosen 1/4 turn counterclockwise, and screw
clockwise again to 15N.m (1.2kgf.m, 11 lbf.ft). Continue to
turn the front of the car, slightly tight or slightly loose, then
fine-tune about 1/6 turn.
d. After adjustment, confirm that the steering is restored,
and if normal, rotate the nut (4A) clockwise to contact the
rubber pad (5) and align the locker (3) with the groove of the
nut (4B). Install the spacer (2) and tighten the nut (1). The nut
(1) has a torque of 100 N.m (10.2 kgf.m, 74 lbf.ft).
e. The front wheel is hung in the air to straighten the
direction handle, and gently push and pull the direction
handle by hand to feel whether the steering mechanism is
smooth and free of jams. When the front fork assembly is
slightly tilted to one side, it should be able to slowly deflect
to the end under its own weight. If it is quickly to the end, it
needs to be readjusted.
3. Maintain steering bearings
If adjusting the steering bearing clearance cannot be
restored, you need to remove the steering bearing to check
whether the bearing, steel bowl is worn or rusted, lacks
grease, etc.
4. Malfunction
Normally rotate the handle, if it feels more laborious, you
need to investigate the following reasons:
a. Whether the steering mechanism is too tight, refer to
the previous steps to adjust the steering mechanism to solve;
b. The steering mechanism bearing is rusty, the steel bowl
or steel ball is damaged, and it needs to be disassembled and
replaced;
c. The front tire pressure is insufficient and needs to be
charged to the standard tire pressure, D350 is 240kPa (2.5
kgf/cm2, 35 PSI) under normal temperature conditions;
d. The column of the lower link plate is deformed and
needs to be removed and replaced.
Front fork
Caution:
●D350 models every 8000km (4971 mile), check whether the
front fork is leaking or deformed, and whether the shock
absorption and rebound are normal.
●Before riding each time, check whether there is leakage in
the front shock absorber and whether the fasteners are loose
to ensure driving safety.
● Bolt torque at the hollow shaft of the front wheel of the
shock-absorbing bottom cylinder: 20N.m (2.0 kgf.m, 15 lbf.
ft).
●When replacing hydraulic oil, use kerosene or diesel to
thoroughly clean all parts. Use a graduated cylinder to
measure 10W hydraulic oil is poured in one time, avoid
