Air compressor wont pump above 60 psi ~ a solution

I have a Central Pneumatic 94667 air compressor from Harbor Freight.

After about a years use, it ceased to bring the pressure above 60 psi.

After reading some of the posts by others, I figured it should be a simple fix, by cleaning up the reed valve.

Upon removing the head of the pump I saw a small amount of foreign material pressed to the plate that mounts above the reed valve. I thought I had it fixed so I reassembled the pump. 60 psi.

I disassembled it again and this time I also removed the orifice plate from the head of the pump. That is where I found the problem, and the source of the foreign material above the reed. Hopefully this helps others.

 Same problem but more
by: Smithaj

I have the same compressor but my valve reed is broken, the same issue occurs (do compressor wont pump past 28psl) but finding a replacement is harder that it looks. The compressor is discontinued. Where can i find a replacement reed?

Another visitor suggests that you can use the blade from a paint scraper, cut to size of course, and that the flexible nature of the scraper blade makes a good reed. Haven't tried it myself.

 Same problem with same compressor (only 40 psi)

Arron,
what type of material did you use to make your own gasket. I feel if I order a replacement gasket it will only do it again later.

Just to confirm, I made a new gasket and it pumps like it always did. Problem solved.
