Motorcycle wheel bearings, as most, require a slight preload so that more
than one ball under the cone (inner race) will support its load. With proper
preload, slight drag should be perceptible. Preload drag is small compared to
drag caused by wheel loads, neither of which are significant regardless of
adjustment. In contrast bearing life is affected by proper adjustment. Adjusting
ball bearings to spin freely unloaded does not reduce operating friction because
a bearing with proper preload has lower drag when
loaded than one with clearance. For high quality bearings, preload should be
just enough to cause light drag when rotating the axle between thumb and
forefinger. Low grade bearings will feel slightly lumpy with proper
preload.
This is later. "Motorcycle wheel bearings" come nicely snug into crowns these
days, but sometimes you still find some that are just put loose in the wheel
hub. To avoid all of them crashing to the ground with the possibility of
vanishing for ever, grab the axle on the side that is still locked in place and
point the end that you've just loosened,up. Now it is time to unscrew the
locking nut almost completely off the axle. Next, unscrew the bearing cone to
expose the wheel bearings to the light of day. Any grease in there? You'd be
surprised on how often I open up brand new bikes and find almost nothing.
Motorcycle wheel bearings support the wheel hubs on the axles. Bearings
require a certain amount of pressure, otherwise referred to as preload. The
specific amount of preload determines the number of bearings that support the
wheel hubs at any given time. Cone flats thread onto the axles and press bearing
cones against the bearings. Adjusting bearing cone preload prolongs the life of
the bearings. With proper preload, light drag should be noticed when spinning
the wheels.Wheels with quick-release levers present a challenge. Closing the
lever alters the preload. Adjusting fag bearings
on wheels that have quick-release levers may take several attempts.
Motorcycle wheel bearings should last for years and provide you with
thousands of miles of travel---but they won't last forever. In some cases they
even fail completely if they haven't been maintained correctly. Part of a
maintenance schedule should include replacement of wheel bearings before they
fail. The procedure isn't that difficult if you have about an hour and a few
small tools. Front and back wheels are similar in procedure to change bearings
and only require slightly different tooling.
Take the wheels off the bicycle beef before greasing the motorcycle wheel
bearings.A mixture of 50 percent white teflon bicycle grease and 50 percent
green axle grease works well on motorcycle wheel bearings.Don't make the
bearing cone too tight when screwing it back into place. Bicycle motorcycle
wheel timken bearings shouldn't have any
play in them and need to roll smoothly.
