(ET) Mower questions

[John Darwin Powers <jdp3 cornell edu>]

Dear fellow electron motivators,

I am now the proud owner of a not-so-new E-15.  In reasonable shape, 
with rust to deal with around the base of the battery compartments ... 
as expected.  I have started to work on the mower motors as the 
bearings are bad and need to be replaced.  The case came apart without 
too much trouble.  The top bearing is firm on the rotor shaft, and I am 
soaking the shaft with diesel oil before I try and pull the bearing.  
The blade mounting hub must come off before the lower bearing can be 
removed.  There is evidence of a woodruff key slot, but no key, and the 
hub appears to be "staked' onto the motor spindle.  I am planning to 
put the rotor in the lathe, and machine off the mower blade hub.  I am 
then planning to machine a new hub from SS.  The brushes appear to be 
in good shape as are the communtators.  Where is the best place to get 
new bearings and temp. switches?
