speedaire 3z176b started knocking

by Jeff Paye
(Huron, S.D.----USA)

older speedaire compressor pump model 3z176b- started knocking.


On weekend I disassembled 2nd stage head and cylinder.

Rod broken at piston wrist-pin. Is there a snowball chance in xxxx that I could find one of those rods?

In meantime I need air for my repair garage.

Picked up used 60 gal 2 cyl Sanborn upright.

Compressor is direct plumbed into tank.

Seems like I should have a pressure bleed off and 1-way valve between tank and compressor,, yes? Maybe could use parts from Speedaire.
__________________
Typically there would be a check valve at the tank to keep air in when the unloader valve opens on pressure cut out. As to pressure bleed off, if you are speaking of the unloader valve, that my be integral to the pressure switch on this model. If you refer to a PRV, and if the compressor doesn't have one, you do want one on the tank side to ensure that the tank and the compressor are not over-pressurized.

Same problem
by: Brent

Went out to turn on my compressor this morning to fix a flat on mower and compressor was not coming on. Pressed the motor shut off button and sounded like alot of knocking in compressor. Took apart the top head and turned the fly wheel. Only one piston was moving up and down. found out that I had a broken piston arm somehow. I, too am looking for the piston arm.

Any luck?

Mine doesn't have anything but one port in the head, the tube leading from it was sheared off. I would like to find a manual too..a friend had the same one and he installed to one of those 5 gal. portable tanks you see at WalMart and the little baby works great!
