I'm sure you are all tired of the saga of the built to "a" spec Ingersol 
Rand compressor from Craptor Supply.  The one that killed its own motor 
in a year.  The one others have reported catching on fire.  The one I've 
concluded only worked as long as it did because the thermal protector 
had to be defective or disabled in the original motor.  (Which is 
probably why some caught on fire.)  The one that tripped the thermal 
constantly on one replacement motor, and the breaker and/or thermal on 
the other.  The one I've been keeping running with an under sized motor 
pulley.  Never mind the debacle with the after market warranty company, 
or the repair shop who reported the repair complete without ever 
visiting my shop.  Even with a much smaller pulley it still trips the 
thermal protector from time to time.  Mostly because I think it has to 
run longer when it cycles on with the smaller pulley, and when I have 
several machines running, all of which use air for various things, it 
has to cycle on more often.

Mostly I can get by for now.  In the last few months I've only had the 
thermal trip on me 4-5 times and I run the shop every day.  Still 
sometimes I run complex operations which can be several hundred lines of 
code on a single tool.  This gives me the opportunity to run an errand 
or go in the house for lunch.  It would cost me more than the cost of a 
compressor if an ISO20 quick change spindle air seal fails and sucks 
coolant up inside the head as it cools down.  Okay the odds of that are 
slim, but it keeps me up at night anyway.

I had decided to bring my dad's compressor to my shop and keep the IR as 
just a backup.  They are functionally similar except the IR has a 5HP 
motor and the one at my dad's shop has a 7.5.    Well, that is still the 
plan, but those compressors are heavy and I don't have anything out at 
my dad's shop (60 miles away) to practically lift his compressor to load 
it into my truck or even onto my low trailer.  Oh, I am sure there is a 
chain fall out there, and there is an old a-frame laying out back, but 
his shop is a quonset hut.  No beams. The a-frame will eventually get 
moved to my shop, but its freaking heavy.  I don't even think I can 
stand it up without the help of a lift.  I know I used it in my youth to 
pull more than a couple V-8 engines.  Scooting it on concrete when its 
on its pads takes a little effort unloaded, and with a big block 360 
hanging from it a bit more effort.  Standing it up in the dirt and 
dragging it around... Anyway.  It will get done eventually, but not 
today or tomorrow.  When I do I'll probably trailer my tractor out there 
to do the job with its loader bucket.

I just ordered a 7.5 HP compressor duty motor for the IR.  IR actually 
sells a very similar compressor with a 7.5 HP motor on it at about 3.5 
times the price of this one.  Then, since I already know all the parts, 
I ordered a new hub for the original pulley to fit the 1-1/8 shaft on 
the new motor.

I quit screwing around with those 5HP motors.  Now I have not one, but 
two unused single phase 230V "5HP" spare motors.  Maybe I'll make a 
couple big belt grinders for erasing the bumpy spots on mountains.  If I 
make a belt grinder or three, which is part of my planned projects, I 
plan to use 3 phase motors for speed control, so not really with those 
5s.  I guess I could build a sheave stack, but turning a knob is so much 
easier than moving a belt.  FYI:  I do have three belt grinders already. 
  a 1x30 and a 1x42 that I use almost everyday for conditioning and 
de-burring parts.  The third one is on a shelf...
