Fresh Air heater 12v fan motor bolts #1337527 Fri Dec 13 2019 07:34 PM

Got a 12v replacement fan motor for my Fresh Air heater. It’s a NAPA #655-1020. I have read that most owners slightly egg out the original holes to mount the motor in the original housing. Just wondering why not drill two new holes in the housing that match the bolt pattern of the new 12v motor. Is there any problem doing it this way? I want to use it as is- not put into the 6v fan motor housing.

This may be of interest, Deve was a frequent contributor here in the past and has some very good info on his site.

I read Dave’s article and it was very helpful. I was just wondering if anyone else has done new holes instead of elongating the existing ones.

Say what you will about Deve, for or against (I have done my share of both), he nailed it on this heater motor swap.
One of the smart things he did was elongating the holes rather than making new ones. This will give you a positive reference for locating the motor to the housing in the proper location. Drilling entirely new holes may lead to the squirrel cage contacting the inside of the housing. The clearance is rather tight.

I totally agree with you Carl. I went with a 12V motor as per Deve's step-by-step installation. It fits nicely and makes the cab warm and toasty!

To add to this, does anybody have a trashed 6v fresh air heater fan motor or the case only?
