3. BEARINGS
3.1 BEARINGS, GENERAL
1. Bearings must be replaced if they are worn,
in the case of pitting (small dents in the
running surface) and/or if the bearings have
been exposed to excess heat (blue spots).
2. When fitting a bearing, make sure that no
force is transmitted via the balls or rollers of
the bearing. For example, by fitting a
bearing on a shaft by pressing on the outer
bearing race.
3. Clean the bearing before fitting it.
4. Avoid dirt getting into the bearing while it is
being fitted.
5. If the instructions specify that the bearing
should be heated before it is fitted, avoid
exceeding the temperature specified. Also
avoid local overheating.
6. Raise the temperature of the bearing evenly
by heating it in the special oil bath. Another
option is to place the bearing on an electric
cooker. Watch the temperature closely in
this case.
