Compressor Id

Hi
I think you have a old bauer K15 about 1977
Part number for a new bauer belt is N2874
But if the compressor has been run with a broken belt [oil pump not turning]
Then the final piston/linner will have had no lubricationand will be either worn or frozen solid.

This the only marking I can find on the compressor

Windy has tagged it. OLD Bauer k-15
If you ran it with no oil pressure, 4th stage is very likely screwed.
You can pull the head off and have a look, or just order it when you buy the belt. It may be seized solid, or be damaged in such a way that you cannot see it, and it will still not work. The piston comes with a machined/honed/ground to fit sleeve, which is inserted into a bore in the 4th stage cylinder.
When you get the new one, DO NOT remove the piston from the sleeve.
The oil pump is a Bosch, and has been fitted on cars, it is the same pump as on my k-14.
Shocking to me that you would run a piece of equipment your life may depend on and know nothing about it or how it works. neither here nor there, but please do not do fills for anybody but yourself until you know what you are doing.
There is no gear train, crank is splash lubed,as are all the other pistons. though the crank does depend on the oil dripping down from the 4th stage a bit.
Porter at August Industries is your best friend on this repair.

thanks everyone for the replies to this post. Very much appreciated!!
there was another gear just like the other two at the center which we removed to use as reference in finding a replacement v belt. it was working fine till the old belt broke.
