Powertech 15kw cooling fan

[Curt Sprenger]

Pete,

If your gen. fan set up is the same as on the 87 PT, which looks like the
fan unit for the house furnace, take the whole unit out and take it to a
motor shop (AAA Electric Motors in Anaheim is where I took ours). I paid
$158.58 for a new motor, clean/paint the housing, new fan/balancing, new
capacitor.
