Answer: 
rpm's 1080, amps 2.8, 1/2 inch diameter shaft, this motor body is deeper (about2 inches) than the standard white painted one but I had no problem installing it in my roof mounted attic power vent. It's quiet, has great touch and seems to be built to last.

From what I can tell it seems impossible to get my hand with an allen wrench in there to remove the fan from the motor. Is there a way to fit that fan down through the bracket that holds the motor?

Answer: 
Disconnect the power cable. Remove the connecting struts (3 bolts). With the fan assembly loose you should now be able to get to the set screw. Loosen the set screw which holds the fan blade to the motor shaft (you'll need an Allen wrench or hex driver). Push aside at least one strut (you may need to loosen it). Pull the motor out, leaving the fan blade in the unit.

Answer: 
Years ago I chose to buy an entire PG3 [Gable] Power Vent system with the purpose to use only the new motor and new fan blade to fix the roof-style Power Vent I already had installed. The original Leslie-Locke motor required annual lubrication of the bearings. the replacement motor has sealed bearings.

Rated 4.3 out of 5 by 100 reviewers.
Rated 4.0 out of 5.0 by Best Alternative for the Price - It Works The motor in our old exhaust fan unit abruptly burned out. This replacement allowed me to repair our ceiling-mounted attic vent fan without crawling on the roof and pulling up flashing. Working in the attic, I removed the old motor by disconnecting it from the supporting struts and the fan blade (3 bolts and one set screw), and disconnecting power cable. The replacement motor is not an exact fit, so a spacer ring is provided to make up the difference. The spacer was very crude, making installation more difficult, but once installed the fan worked beautifully. September 6, 2016
Rated 4.0 out of 5.0 by Gable fans Didn't carry this motor in store.. so i ordered online, received no problem , replaced motors.... one small issue , if you want to call it that! The clamp spacers were bent crooked ,, I had to rebend them to fit correctly , added a few minutes to install .. no big deal .... fans now working no problems August 30, 2016
Rated 5.0 out of 5.0 by Exact replacement for my attic fan. This is the exact replacement motor for my attic fan. Side by side they match exactly except for the color. Even the electrical ratings are an exact match. The original is date coded 7/1995 and the new one is date coded 3/2016. I didn't need the band as the original clamp system fit perfectly without it. I see where many reviewers have trouble with the band and overall install but I swapped mine out in 20 minutes start to finish. I did have rather easy access to my unit though. It actually took me longer to find the correct circuit breaker to kill power to the unit for the swap! August 4, 2016
Rated 5.0 out of 5.0 by Works great I ordered this motor to replace the wimpy original white motor (the replacement that can be found in-store) that came with my power roof ventilator. The original motor lasted just a few years. I installed the motor from inside my attic, which is easy to get to. After loosening the 3 bracket screws and some gentle custom bending of the 3 brackets, I removed the old motor and swapped the fan to the new motor. Reinstalled and added a new thermostat from HD. This motor is much more powerful than the original and really sucks. The cost is about $11 more than the cheaper short-term replacement motor. Works great and really cools down my walk-up attic. June 17, 2016
Rated 4.0 out of 5.0 by okay Motor was difficult to install do to location. Additional ring that accompanied product added to difficulty in installing. Runs well so far. August 17, 2016
Rated 5.0 out of 5.0 by No problems at all. The motor was as described. No problems found using this motor as a replacement. September 6, 2016
Rated 2.0 out of 5.0 by Not an exact duplicate of the original The problem with this direct replacement is that it is not a direct replacement. This motor requires an adapter ring(included) that makes it incredibly difficult to hold up and clamp in place in an overhead position. Then when clamped tight it relies completely on the friction of the three quarter inch bolts to hold everything tight because the ring clamp is not secured in a groove like the original motor was. It makes me afraid that it will vibrate loose, drop and burn out with time. July 28, 2016
Rated 5.0 out of 5.0 by Ceiling Vent Motor Although I have only had this motor installed for around 3 weeks, so far it has performed as it should. It's interesting that if you buy a vent housing assembly, you get a 10 year parts warranty. If you buy just the motor, you only get 1 year. I tried to buy the whole assembly but I believe it's been discontinued. This is to replace a motor in an existing vent and I wasn't sure if the motor in the new assembly would work in my old assembly (so as not to have to get on the roof and disturb the shingles. It has an adapter ring that will allow it to fit into different sized openings and the power wires are long. July 20, 2016
