When fitting new bearings the parts should
be lightly lubricated with grease.
The bearing should be driven onto the shaft
by pressure on the inner race only using a
short length of tube placed over the motor
shaft.
On larger motors it is easier to raise the
temperature of the bearing using an oil bath,
oven, or induction heating. The temperature
must be controlled to 120°C maximum.

Having dismantled the motor, maintenance
can be carried out to remove all dirt. For this
purpose, the use of an air line supplying dry
compressed air under comparatively low
pressure is best, as a high velocity air-stream
can force dirt into the spaces between the
windings and insulation, etc. Greaseremoving solvents should only be used very
sparingly to avoid damage to impregnating
varnish or insulation.
Motors should be re-assembled in the
reverse order from dismantling,
