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 4.4 out of 5 by 108 reviewers.
Rated 5.0 out of 5.0 by it worked for an older unit I have an older roof vent fan. The motor stopped working. They no longer make that motor. This motor seemed to have the same dimensions so I ordered it. It fit into my fan unit okay and the wiring to the temp and humidity sensors was easy to connect. October 18, 2016
Rated 5.0 out of 5.0 by Works well This replaces my 1/2" thinner attic fan motor. This thicker motor still fits the existing set up. The metal housing band wraps around the "waist" and the motor is just 1/2" lower. This thicker motor gives me more horsepower. Installation by our handy friend seemed straight-forward. We reused the thermostat, fan blade and the original housing so it was a cheaper replacement. We are happy with the purchase and the cooler attic. Note, for those on the fence about hiring a contractor to replace the motor, try taking out the old motor first. (It'll be broken regardless so no big deal if you can put it back.). If you can take it out, you should be able to install the new one. If not, get a contractor who will charge about $125 for the relatively simple installation. September 27, 2016
Rated 3.0 out of 5.0 by REPLACEMENT POWER VENT MOTOR FOR PR3 AND PG3 SERIES VENTS The motor arrived in reasonable time and was as advertised, but replacing this motor with the roof vent still in place was one absolutely difficult job because of gaining access with a ladder from the attic, through the rafters and existing home wiring, with my steeply pitched roof . The access to the support brackets was very difficult, and you cannot remove the brackets with the vent while its still installed in position- you must unbolt the 3 arms of the mounting collar around the motor and then bend them back in order to have enough room to bring the fan and motor assembly down together as a unit. You cant access the fan blade set screw until the motor is down. Once the mounting brackets were bolted back in place supporting the motor, the wiring was easy. Not a job for beginning handymen or those that cant balance on a ladder. October 18, 2016
Rated 4.0 out of 5.0 by Attic Fan Motor Exactly as advertised. Installed motor and it works. October 2, 2016
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 5.0 out of 5.0 by Good motor so far I installed this fan motor a year ago with no problems. It still runs quiet and vibration free. I wish the bearings in it were sealed instead of open bearings, it would most likely operate much longer. I oil the open bearings once a year before it gets hot for seasonal maintenance hoping to get a few more years of life out of it. It does its job by keeping my attic cooler in the hot summer months which makes me happy. I'm glad I put in the extra research, paid a little more for it, but found this more reliable motor. September 11, 2016
Rated 5.0 out of 5.0 by Exact replacement motor I needed This replacement attic fan motor was the exact horsepower rating I needed. Home Depot use to stock this motor, but now only offers it to be shipped from their warehouse. i found shipping to be a little slow, but it arrived in new condition. September 20, 2016
Rated 4.0 out of 5.0 by Replaced with 24" direct drive motor I wanted some thing that would last longer so I used the Master-Flow-Replacement-Motor-for-24-in-Direct-Drive-Whole-House-Fan-MOTOR24DD/204676203 to replace the PR3 and PG3 Series Same physical size. More HP. But it does not come with the spacer that they provide with PR3 and PG3 Series motor. So I used some copper wire instead Works beautifully. September 20, 2016
