WHEEL BEARINGS
1. Replace when bearings exceed end play service wear
limit of 0.002 in. (0.051 mm).
2. Inspect any time the wheels are removed.
a. Inspect the play of the wheel bearings by finger while
they are in the wheel.
b. Rotate the inner bearing race and check for abnormal
noise.
c. Make sure bearing rotates smoothly.
3. Check wheel bearings and axle spacers for wear and
corrosion. Excessive play or roughness indicates worn
bearings. Replace bearings in sets only. See 2.5 SEALED
WHEEL BEARINGS, Inspection.
WHEEL SPOKES
Spokes that are too tight can draw nipples through the rim
or distort hub flanges. Spokes that are too loose can
continue to loosen when put in service. Either condition
can adversely affect stability and handling, which could
result in death or serious injury. (00286a)
If nipples require more than one full turn to tighten spoke,
remove tire to check that spoke protrusion has not dam-
aged tube. (00526b)
Inspect vehicles with wire spokes as follows:
1. Raise motorcycle wheel off the ground.
2. Lightly tap each spoke with a spoke wrench. Loose spokes
sound dull and must be tightened.
3. Tighten spoke nipples to torque specified in Table 1-8.
4. If more than a few spokes are loose, true the entire wheel
following procedure under 2.9 TRUING LACED WHEELS.
