 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...

Aircompressorsdirect gives 611 Lbs for a 7.5HP IR.
 Just swap the motors??
 
I considered that, but I want both compressors 100% or what's the point of having a backup.
I can haul heavy stuff.  Its just time consuming, plus the 2 hours (+/-) of road time.  Also, its going to take time to move one compressor in and the other out.  I am considering an "outdoor" compressor closet, and plumb in both compressors together.  Just have valves to shut one off from the distribution lines and only turn on one or the other.
That might actually be faster than a swap, and down time would be much less too.
Might see about some sort of transfer switch so I can't accidentally turn them both on at once.
It would be nice to get the compressor noise out of the back shop.
