Clean valves?

by Richard
(Chattahoochee fl.)

Just picked up a. 3Z180 that has been sitting for 7/8 years .

just got thru wiring the 5 hp 3ph.

Pumped up to 100 psi pretty quick ,stopped it and the governor bleed off was leaking and a small amount coming out air filter.

The back flow valve was shot,that should take care of unloader leaking but is worth trying to clean up the valves or just run it a while and see?

I don't know that MMO will help, but probably won't hurt, either, as long as it's OK with you to be in your air...

10-4 it's going in the direction of the arrow, the plate on the psi switch says 175 on high side, l heard some pinging sounds as it was getting up around the 100 mark.would it hurt to add a little marvel mystery oil in air intake ? Thanks

I'd run it awhile and see how it goes.

Did you verify that it's running in the right direction?
