Followup Powertech 15kw cooling fan

[Pete Masterson]

Just got the fan and motor back from the service center. Hooked up
the wires, tightened the screws, turned on the generator, and the fan
started right up.

Bay Area prices seem to be involved -- just about double the Anaheim
price. $320 at Koffler Electrical Mechanical Apparatus Repair, Inc.
Included a new motor (GE brand with sealed bearings), clean/paint
housing, rebalance the fan, new capacitor.

I note when I took the fan housing off the radiator that there was a
small bit of dust piled up on the radiator. A thorough wash down with
the garden hose cleared out the accumulation. (But it was pretty
minor and not the cement-like oily dirt that accumulates on the
engine radiator.)

Tomorrow, I change the generator oil and filter. (Oboy!)
