●Too small steering mechanism clearance will cause
inflexible steering and accelerate bearing wear. When it
is too large, it will cause driving jitter and abnormal noise
when braking.
1. Check the steering mechanism
a. Support the front wheel with a suitable tool so that
the front tire is hung in the air and then rotate the
direction handle left and right to confirm whether the
rotation is flexible and smooth; whether the cable and
cable show signs of being pulled.
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.
Refer to the steps to remove the faucet lock in the
section "Replace the lower link plate" in the "Front Fork
Assembly" of this manual, and remove the storage box.
Remove the faucet lock.
b. For the convenience of explanation, other parts are
hidden here. First use a 38-42 hook wrench with a
thickness of 6mm (0.24 in) to loosen the adjusting nut
(1a); move the lock washer
⑵
up and then loosen the
adjusting nut (1b).
c. If the steering is heavy, loosen the adjusting nut
(1c) counterclockwise. First screw it clockwise to 35N.m
(3.6 kgf.m, 26 lbf.ft), then loosen 1/4 turn
counterclockwise, and then screw it to 15N.m (1.2 kgf.m,
11 lbf.ft).
d. If thre is any looseness, screw it clockwise to
35N.m (3.6 kgf.m, 26 lbf.ft), then loosen it
counterclockwise by 1/4 turn, and then screw it to 15N.m
(1.2 kgf.m, 11 lbf. ft).
e. After adjustment, confirm whether the steering is
restored. If it returns to normal, turn the nut (1b)
clockwise to touch the rubber pad (3) and align the lock
washer (2) with the groove of the nut (1b) and (1c).
Tighten the nut (1a) to 100N.m (10.2 kgf.m, 74 lbf.ft).
f. 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.
