Thanks for the post!

Sanborn was bought out by Coleman Powermate, around 1998.

This is certainly an old model, I don't have the breakdown on this specific unit, but I'm familiar with the pump and the set-up.

The pump is a cast-iron, inline twin-cylinder "143" model pump and most parts are obsolete for it, I'm afraid.

I've attached a .pdf breakdown of a very similar gas model with the same pump...does this resemble your compressor?

Pressure Gauges are easy enough to replace, it's universal part.

The Regulator may be as easy. Does your regulator have a square or star-shaped plastic knob, per the attached diagram? Or, is it more of a universal in-line Regulator like the one you see on our website (at the below link)?

If you have the small, hollow-style air filter elements they are still available, but are pricey; the part# is 019-0053 and they go for about $35 each. It may be best to use a different type of filter assembly, like on our site at the below link. These are twist-lock filters which replace elements (which are paper filament). Just confirm your filter threads are 1/2" NPT (actually they'll measure 3/4" if you measure the outside diameter, which translates into 1/2" MPT).

As for the Belt Guard/Shroud, this is now an obsolete item, unfortunately. You can probably find one and retro-fit it to you unit...or have a welder fabricate one for you.

I hope this helps, feel free to upload some photos of the compressor as I can probably give you more detailed information.

Glad to help if I can Joe, and I think you can get this unit running in top shape even if you can't obtain some of the OEM parts. Obviously you're mechanically inclined so it shouldn't be a problem.

Of course, the belt guard is most important as it's obviously a safety issue (I should know as I once got a finger stuck in the pump flywheel under the belt....not fun). Yes, this should be easy enough to fabricate if you have the capability.

I would certainly go for aftermarket filters. Our canister-style threaded filters have twist-lock covers and the elements are easily replaceable.

IF you need to replace the Regulator as well, that's a very standard in-line regulator, like our REG0250M (1/4" FPT inlet/oulet) or REG0375 (3/8" FPT inlet/oulet). If you just need the Gauge, good deal!

Honestly, as long as the pump pressurizes and doesn't knock, and your tank holds pressure, it's worth holding on to and using. That pump is the heart of the unit and a solid one at that...if it pumps then I'd keep it.

Thanks again for the post, hopefully you can wring out additional years of service from this unit.
