Need help

[Mhardee86]

I recently inherited an air compressor. 500a60 sanborn. I recently got it working around but now I can't get it to hold air or more than 20 psi. I did notice that there's a leak in one of the gaskets on the pump. Would this be my issue or something else?
The motor seems fine and the belt is moving with the motor and pump.

Any help will be greatful

a leak will cause your problrm

I've looked around and they no longer sale the gaskets for the cylinder head. Any other options?

Would liquid gasket type application work?

I don't see why a decent gasket maker wouldn't work. I know head gaskets are super finicky but its an air compressor. Might as well give it a try?

too much heat for gasket maker in my opinion.

It works for header gaskets so I think it would be fine from a temp perspective.

I've never done it, but I think you can buy sheets of gasket material and use a ball peen hammer to literally hammer out a gasket. I remember back in the day my auto shop teacher mentioning this "old" technique.

fine. try it & report back. I wouldn't myself.

You can buy sheets of gasket material at the autoparts store. They have different kinds for heat resistance, fuel resistance. I would assume the ones you use to make carb gaskets would work. The exhaust ones have a metal middle layer which makes them difficult to cut, just an FYI.

Make one.

I bought a Cry-cut for that purpose.

Permetex aviation sealant.

Wanted to update everyone that I was able to use 90min gasket maker from my local Walmart. This worked great. I was finally able to get the pressure to build and 120psi before it cutoff, as normal.

Thanks to all who helped.

great!

I used 90 min gasket maker and it worked great.

Just think how quick you could have fixed it with 5 minute gasket maker, or even instant gasket!

Instant gasket maker is NOT the right thing to use on a head gasket. It WILL fail after many warm up/cool down cycles. How hard is it to make one out of proper gasket material

I don't know if you can still buy thin sheets of copper and asbestos to make a gasket.
