Is the centrifugal unloader assembly screwed into the crank shaft or pressed ?

looking for specs on a 3z868

I just got a 3Z868 and was wondering what the CFM rating is. Also who makes the compressor. The compressor has the numbers 1398 on the side. It looks to be a 4 piston v style compressor. The motor is a gas powered Kohler 8hp model number K181T. Any info on this unit would be helpful.

Hey Seth. I don't have the specs (hopefully a reader will and supply them for you) but as a rule of thumb you should be able to get about 4 CFM of compressed air at 90 PSI for each HP of motor size.

Cheers,

Bill

1398
by: Just A Guy

You aren't going to believe it but that air compressor is still made. ( the compressor itself) The V360 from american eagle is the same compressor. How do I know that? We blew one up in a Goodall 5000 sevice pack and I didn't want to pay the outrageous cost of a new one. After much digging I came up with this exact replacement.
1398 casting number on the cly.
bore 2 5/8" stroke 2"

Gasket kit for a SPEEDAIRE 3Z419 2hp, single stage compressor,

I had been using this with a slight leak at the head as I was looking for a gasket set so I could rebuild the pump. Well new gasket anyway. I was not planning on doing a full overhaul to it.
Well, it blew the gasket and you would not want to be standing next to it now. Man, is it LOUD!!! Thing is, is I can't find a gasket kit anywhere for this model number, 3Z419. I am trying to find out if there is a newer number that will crossover to the one I have been looking for.

Single stage should be pretty simple - make your own.

Automotive sheet gasket should work fine.
