Question can anyone cross a Sears Whole House fan motor?

I have a Sears 758.638700 whole house fan with a #13534 motor (Sears quotes an alternate motor number of 8200). Sears wants my first born as a replacement cost, can anyone cross this? I ran into this in the past and the only non-standard difference was the direction of rotation. I'm sure that Sears doesn't make the thing, they just mark it up after they buy it. Does anyone have a source for these? Thanks!

Update: it has an Emerson S63CXELB-5056 motor

If you can buy from Grainger or Johnstone those are good starting points if not you could get in touch with your local motor store as an example we have one here in Northern KY. If I take a motor in to them they will match it up usually on the spot and if they can't do it then they can order me one in at alot lower cost than a retailer would charge me.

Anyone else with similar situations might try Dayton Motor 6K426. It matched my old Emerson motor in everything but size. This new Dayton is much taller (about 2"). The 8200 motor from Sears only had 1 speed and was quite a bit more money. I got the Dayton for about $200 from Grainger, modified my motor mount a bit and it all works. The one issue is that I could not get a nice straight path for the belt because of the additional motor height so the belt may wear much faster. The whole thing runs far quieter than previously so I'm happy for now.

Cheers, Dave Raiman

Dave....thanks for the additional info in this fairly old thread.

You could also have used the Dayton 6K-778 which is almost an exact replacement.
