Hello fellow listers:
Fan motors can be lubricated and modified so that they may be lubricated in
future. It can also be done without removing the motor if access to the
end of the motor can be achieved. Most heater blower motors are in a
stamped steel case which contains a bushing at the end opposite the motor
shaft. The bushing is pressed into the case from the inside and is usually
not provided with an oiling fitting. This can be provided however by
simply drilling a small hole in the end of the case into the center of the
bushing. Use care, and a bit of grease, to prevent swarf from entering the
bushing. Once the hole is in place, a few drops of engine oil and a bit of
masking tape will ensure quiet. However, if the bushing is so worn that
the shaft wobbles it will be necessary to replace either the bushing or the
motor.
The shaft end of the motor, if it is accessible, can usually be lubricated
directly.
Note that this method may not work on the TR6 blower motor as I haven't
seen one to determine what type it is, but this system has served me well
in the past with a variety of motors.
