I have just aquired this pump it has C1208 on it. It supposedly came off of a Sears model 106175541. From what I was able to gather that was a 1 to 1 1/2 HP air compressor, but, some had a 5 Hp motor. I cross referenced the pump and it also can be used with up to a 5 HP motor. I would really like to put a 3 to 5 HP motor on it if possible. I would greatly appreciate any feedback.


Thank You,

John Cardoso.

5HP motor

Yes, you can use a 5HP motor with this.

What you need to know (and I didn't get a lot of satisfaction looking for this ) is the max RPM of the pump shaft.

If you can determine that, or even get the sizes of both pulleys for a given HP and motor RPMs, we can figure out what you need for a 5HP motor of a given RPM.
