Sears Model 919.167340 only build to 20lbs

Compressor runs but will only build pressure to 20lbs. When the pressure gets to 20lbs the air intake stops sucking air. Before this point it wil suck my hand hard.


There is a needle valve just prior to the switch assembly. Air escapes from there via a small slot that appears to be designed for that.

My compressor is Sears Model 919.167340 33 gal 6hp. Any help would be greatly appreciated.

Finding pages
by: Bill

There are search boxes on many of the pages in this site, including the home page linked from the "How To Find It" section in the left nav bar.

There is also a sitemap page linked from the same place which has almost every page on the site listed by categories designed to help folks find what they are looking for.

I'm having a difficult time maneuvering the site. It's me not the site. Is there a Search option?
Thank you Doug!

Re: Check Valve stuck open.
by: Tommy

I'm not experienced with the parts/names. Where would I look on the compressor? Is there a way to troubleshoot a "Check Valve"?
Thank you for your help!

There's a page here about that, but it sounds like your check valve is stuck open.
