Regulator Screw/O-ring
Question by Mark 11/18/2009

My regulator is working fine, but there is a screw and O-ring on the bottom side that holds in the spring - it is made of cheap pot metal and broke when I tried to tighten it. Can I purchase this part without having to purchase the entire regulator assembly?

WONT SHUT OFF
Question by SCOTT HURD 10/29/2009

My air compressor won't shut off when it's full. It just keeps running and is really loud. What parts do I need to replace?

in suffient compression
Question by thomas 09/28/2009

Should you see daylight between the cylinder and piston when the piston in down? Is it a taper cylinder like a two stroke nitromethane motor?

Compressor Siezes
Question by Murray Bass Jr 09/28/2009

After sitting for a few days my compressor will not start. Compressor appears frozen. A helping hand will usually get it started.

I was having the same problem. Took it apart to find that the bearing behind the counter weight was shot. Still looking to find a place to buy new bearing and to find a way to get the old one off without a blow torch!

Question by kim kusske 09/06/2009

My Ridgid of45150b air compressor will sometimes not restart on air draw down and will kick the circuit breaker. Is the pressure release valve causing this problem?

Hi Damian,

If the pump runs continuously but never builds over 25 lbs of pressure then you likely have a worn out piston and cylinder. The piston and cylinder are sold as a kit which is part #17968, available from http://ereplacementparts.com.

Good luck with your repair!

pressure regulator trouble
Question by michael 08/18/2009

I recently replaced the piston an cylinder sleeve on the oilless rigid compressor only to find that the pressure regulator was leaking. I purchased a new one an its doing the same thing. It only leaks in when turned to certain positions. I'm stumped please help.

rod bearing
Question by steve 08/10/2009

How do you order the rod bearing? I thought it came with the rod piston package. I don't see it listed anywhere. The motor is fine, I don't want to replace it. The whole compressor costs less, new, than the motor does by itself. Thanks

Hi steve,

It looks like the only way Ridgid sells the bearing is with the motor assembly. I think I would remove the bearing and take it to a local bearing supplier. They may be able to find a new one that will work.

Good luck!
