I was prepared to pay someone $500 to replace my failed attic vent.
On a lark, I decided to take a ladder to the attic to see if I could find the model number of the unit that the builder installed. Fortunately, the label was still present and a google search produced this item - it made my day!
The video on the HD Website tells you all you need to know about how to go about replacing the motor.
I did, however, find that the diameter and shape if this replacement is slightly different than the original but it still fits - just be sure to tighten all 3 clamp bolts on the vent frame.
The toughest part of the job was tightening and loosening the fan blade, due the the fact that you need to reach in back of the motor, through the blades. 'definitely worth the effort, considering the money you will save!

Replacement motor for attic vent. The last one lasted 8yrs. Was fairly easy to replace (is done from inside, no need to remove vent cover or housing) and quieter than replaced motor.
Hints: Make sure you have the correct size allen wrench available to remove the fan from the old motor shaft and replace on new.
Slide fan up or down on new motor shaft before tightening, making sure fan blades do not scrape motor supports when tightened & turning.
Hand turn fan, making sure blades are as equally level (easily bent to level out if necessary) as possible.

Although the replacement motor was a bit wider than the original, it fit perfectly. After loosening the allen screw on the fan blade loosening one screw on the motor bracket allows for the easy removal of the old motor and installation of the new motor. The entire job took me less than 45 minutes.

FAN-tastic
I purchased the PR2-HI22 in 4/8/2001 and installed a lighted inline switch in the closet to turn the unit off in the winter. The light install is attached to the dead side of the wire/switch, so when switched on there is a light indicator. I have not replaced the motor but purchased this replacement motor, just in case it is needed. I feel most who have had issues set the trip level too low which results in higher fan operation. Although, if you follow the instructions it recommends 105° F, I set the thermostat to 118° F. I also did my best to make sure the thermostat gets plenty of air flow when the motor is operating. Hope this information will assist those who have had issues.

Consider it a consumable
Razor blades are designed to wear out after a certain number of uses and so too are these motors. I recently purchased a new residence and the seller had two of these motors on hand to replace the two failed ones up in the attic.
I placed a thermo probe in the attic prior to replacement - temp reached a high of 141 deg F. After replacement we are down to 102 deg F.
As others have said, you need 2x 7/16 wrenches and an allen wrench (mine required 5/32 - odd). The bolt/nut removal for the housing is easiest when you have one socket drive and one closed end wrench.
The fan is fairly loud when running but I can't hear it once my attic access door is closed.

Excellent Boat Anchor
I would be on my 4th (maybe #5) motor in 12 years, but I don't know if I'll keep buying this boat anchor anymore. First one was installed Summer 2009, last one was installed 5/19/2020 (yes, I marked the day I installed it), this weekend 4/20/2021 I checked it and it won't turn on. So between 2009 and 2021 I've had to have multiple replacements with the last one not lasting a year. I tried finding my last disgruntled review from 2020 which SURPRISINGLY cannot be found now.
Just understand, this is a temporary product that will require nearly annual replacement.

Drop-in replacement for the old Leslie Locke PG1/GM20 vent fan in my attic. Replacement of the motor itself was easy, but had to use a spare wire nut since the old one was tiny and a piece of the old wire broke off inside it. Only other tricky part was navigating in the tight attic space.

Not compatible with 3-point bottom bracket mounts
I have replaced attic fan motors multiple times. My fan housing has a 3-point bottom mount bracket and previous motors had 3 bolts holding the casing together. This one has 4. No problem because all other attic fan replacement motors in the entire world have multiple holes around the stator core that are aligned with the square holes around the outside of the motor casing every 30 degrees which allows the installer to move the bolts (or add additional bolts) to match the mounting brackets. This motor's stator core only has four holes at 90 degree intervals which prevent this type of adjustment. It is painfully obvious this was a insidious decision on the manufacturer to force the home owner into buying an entire attic fan (shroud and all).
DO NOT BUY THIS MOTOR UNLESS IT EXACTLY MATCHES YOUR EXISTING ATTIC FAN!
I will avoid buying Master Flow products from now on if given a choice.
