Roger,
I just cleaned, painted and reassembled my heater box - checked, cleaned,
oiled the motor, etc. as part of the restoration on my '76 TR6 which was
built on 7/5/76 - 10 days shy of the last TR6 build date.....it's definitely
a 4 blade unit - not a squirrel cage fan.
I think I'd go to Grainger or some other industrial/commercial retailer that
sells electrical components and attempt to match one up with an
over-the-counter motor. It doesn't appear to be an unusual size. As far as
finding one with the exact rpm specs for the 2 speeds - I'd get one with as
close as possible rpm ranges. I don't know how you'd get a squirrel cage to
work effectively (using the same motor mounting) since the motor shaft and
air flow are both vertical....doesn't a squirrel cage generally blow air away
from the plane of the shaft by 90 degrees? I'm relating to my furnace
fan.....
