Check the front
wheel axle bearing.
Disassemble the front
wheel axle bearing.
Measure the deflection
of the front wheel
Check the front
wheel cover tire
[6] Place the front wheel on the calibration stand
and rotate the front wheel at a high speed. Check
the front wheel for any abrasion and the free
stroke. Check whether the front wheel bearing is
abraded. If it is abraded, it should be replaced.
Caution
If it makes a noise or the free stroke is too wide,
the bearing must be replaced. The bearing should
be greased when installed, and bearing oil seal
should be outwards.
[7] If the front wheel bearing is severely worn and
damaged, apply a remover to gently knock out the
bearing and install a new bearing.
Caution
The front wheel bearing should be greased when
installed, and bearing oil seal should be outwards.
[8] Place the front wheel on the calibration stand
and check the deflection of front wheel. Rotate the
front wheel by hand and measure and read the
front wheel deflection value with a dial indicator.
Limit for maintenance: radial 2.0 mm
axial 2.0 mm
Caution
If the front wheel deflection value exceeds the
above maintenance limit of 2.0mm, the front
wheel should be corrected or replaced.
[9] Check the cover tire of front wheel for any
abrasion. The abrasion of tread pattern of the front
wheel is subject to a maintenance limit: 2.00 mm.
In the use of the motorcycle, if the front wheel tire
pressure is insufficient, check the tire valve core
first and then the inner tube for any air leakage.
Caution
If the inner tube valve core leaks, it must be
repaired or replaced.
If the inner tube leaks, it must be repaired or
replaced.
