Dear Robert,

Once you've gone to all the trouble of taking the dash and heater box
apart, it seems to me to only make sense to go the whole way and
disassemble the blower so you can properly lube both bearings
including the felt oil reservoir rings which aren't accessible
without removing the motor.

That being said, it's the rear bearing that runs out in the open and
gets showered with dust all the time, as the forward one is protected
by the blower wheel itself; which is why the Mullendore Port is so
effective at stretching out the interval before you simply have to
take the dash off.  Until spring, for example.

Yours,
David
