SOURCE: Will not build up pressure
If this compressor is dry type with no oil needed, then it may have a worn cylinder and/or piston ring. With flashlight in hand, look under cylinder with piston in upper most position. If you see scratches most likely it needs cylinder / piston kit. Not to worry, not too expensive. If you compressor has a crankcase with oil, then you may have problems with valves in the head. Cracked or dirt under headvalves will prevent pressure from building. Finally there may be one or several leaks in the tubing, check leaks with soapy water. enjoy

Campbell hausfeld has all their manuals on line at www.chpower.com / you can enter the model # of the whole unit or just the # of the pump. Also you can enter just a partial number example wl650 for a list of models is that range. Use caution when installing gaskets for chpower oiless pumps. Some of their gaskets are very brittle. After installing parts, turn pump by hand to make sure all parts are in their proper place and that there is suction. Enjoy

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

I would say the head or block is warped. Use Majic Marker to cover the mating surfaces , the head can be rubbed on a flat surface like a cast iron table saw to find the high spots, or the head can be rubbed on the block.
Careful work with a good flat file will remove the high spots.
The torque value sounds low even for an aluminum block, you could check with a small engine shop to get their opinion.

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
