(ET) Blower motor operational.

[Christopher Zach <cz bunsen crystel com>]

Worked on the blower last night; the rear bearing looked like someone 
had hit it with a screwdriver or something, there was a deformation in 
the race. Pulled the bearing, replaced it, then cleaned and oiled the 
lower bearing to see how the motor ran.

Hint: When assembling the magnet sleeve to the motor be careful with 
your fingers: The blades on the motor's internal fan are sharp and it's 
easy to pinch a finger between a blade and the magnet as the armature is 
pulled by the magnets.

Assembled the motor pulls 3 amps at 12 volts, spins cleanly and pretty 
quietly, so I think I'll button it up and put it back on the bracket. 
Then it can go in the shed till fall and I'll buy a 36 volt contactor so 
I can turn it on and off from the mower switch.

Next up: Wheel for the trailer so I can get it off the driveway :-)
