Okay kids,

        I have come to the conclusion that I must replace the motor on my 
compressor.
The original is a 1 hp, 3 phase, which rotates at 1720 rpm.  After calling 
around this 
morning and getting prices on new  1hp single phase motors, prices vary from 
$175 to $230.

        I called a used motor guy who recommended I check the Harbor Freight 
catalog,
saying they sell new motors for less than he could get me a refurbished used 
one.  I open 
the catalog and see my options are:

        1800 rpm, 1hp motor for $99 - 5/8" shaft - #56 frame
        1800 rpm, 1hp, 7/8" shaft, #143T frame for $109
        3600 rpm, 1hp, 5/8" shaft, #56 frame for $72

I guess my questions would be, can I go with the higher rpm motor?  will this 
be detrimental 
to the system?  or is more NOT better in this application ?  Anyone know the 
dimensions
of the mounting bolt patterns stated above?

The mounting brackets will have to be redrilled to convert from metric to 
standard, as will the 
pulley.  I suppose I could get a similar pulley to mount on the 5/8" shaft 
locally, but I wonder 
about how close the ratio must compare to original.

Thanks in advance for all your help and advice
