WHEEL BEARINGS AND ADJUSTMENT
The wheel bearings are of taper roller type. See illustrations. The outer cups for the
rollers are pressed into the hub shell. They have a fixed location one side and an adjustable
location on the other. The fixed location is provided by a circlip in a groove cut in one
end of the hub shell, while the adjustable location is regulated by a screwed ring that is
threaded into the opposite end of the hub and the position of which can be locked by an
encircling nut.
On all wheels the adjusting ring is located on the right-hand side.
It is rarely necessary to make adjustment to wheel bearings. It is most important they
are not adjusted too tightly as this would quickly ruin them. There must always be a
slight amount of end play. This should be about .002", which represents a just perceptible
rim rock. (Not more than 1/64" rock.)
A service method of ensuring correct adjustment is :
Slacken the lock nut.
Tighten the adjusting ring until all slackness has been taken up.
Slacken back the adjusting ring exactly one-half turn.
Tighten the lock nut, making sure that, when doing so, the adjusting ring does not creep
round and that the cover disc is positioned to permit grease gun application to the
nipple.
