Craftsman compressor 921.166370 reed valve look like pics

SOURCE: coleman compressor no build up of pressure

Parts for coleman are available at www.mastertoolrepair.com your compressor is listed as L0502710. If however you like to tinker, you can make a pretty good reed valve out of aluminum can material or other (any ideas?). It is fairly easy to cut, does not last as long as factory stainless steel, but for short term, why not? Good Luck

What pressure is it popping off at? You might have to adjust the pressure switch to a lower setting.

I believe in your model of air compressor, when you take apart the head portion to your compressor you should have four reed valves. When you have it apart, there should be two "grooves" on the bottom "plate" and two "grooves" on the top plate (where the reed valves go). the bottom part is easy (as you should already know) to set in the reed valves, but as i have also found out, as you probably have, that its a little more difficult to line up the other reed valves to thier "grooves" on the upper "plate". What you do to make sure that they stay in place is dab a little oil or grease on the reeds and place them in the upper "plate grooves" and carefully set the upper plate back in place where it goes on the compressor. It will hold them in place long enough to install it on the compressor and the small amount of grease that was there will quickly be burned up with no effect to the opperation to the machine.
Sorry, long winded explanation. hope this helps and if it didnt get to you soon enough i hope it helps out in the future. :-D

Without knowing specifics of your unit, If there are three reeds, then two are probably for intake and one for exhaust. Intake reeds should be on the piston side of the valve plate, discharge reed should be on the head side.

There should be a divider in the head side to separate the inlet from the discharge. Make sure the valve plate is turned so that the air from the air filter side goes to the side with the intake valves, and the air from the discharge valve should go to the side with the pipe to the tank.

If you have oil coming out of the oil fill and dip stick you most likely installed the reed plate upside down. Usually it says this side up or there is an arrow pointing up on the reed plate.
This is a good sketch of compressor and reed valve assy.

Usually the reeds are on top of the plate facing downward. If you have just a reed disc.. then the disc will need to be inverted.

Thanks for Choosing FixYa.
