Dont leave it plugged! Take the things to your nearest battery expert specialist. Find in the directory. They'll rebuilt it, but you might need another loan on your house...

SOURCE: My cylinder got gouged by the piston. Can I bore

It depends on how deep the gouge is. Having it bored and a new oversized piston may set you back more than a new stock piston and cylinder.

I'm not sure what type of engine you have but you mentioned valves so I assume a 4 stroke. I guess I could go look it up buy my experience is that Sears web site doesn't pack a whole lot of information. But it hit me reading your post that maybe the timing could be off 180 degrees. Could you pull the plug, put it back in spark plug wire, ground to frame and see if it sparks about the same time the piston comes to top dead center?? I don't think this type of engine has a timing chain but if the flywheel has has magnetic pickups on it that fire the ignition could it have been put on wrong? This is just a quess. Sounds like you know what you're doing and the flywheel probably has a keyway but that seems like enough compression to fire and you have spark and gas.

Campbell hausfeld sb504000 nailer wont recycle. fires and sticks forward. had a new wearband made for the piston head. i cant seem to find parts nor service locally. the result is the same. need help.

Piston stays down when piston oring is too tight or too loose, discharge air passage is restricted, or check band not in place on outer part of the cylinder. Piston should be easy to push down in cylinder but not just fall all the way down. The check band is usually a band of rubber or an oring that covers a series of small holes drilled into the lower outer portion of the cylinder. Make band out of bike inner tube, or if oring, any oring that fits snugly will work. Good luck

I own a Campbell Hausfeld model WL650800AJ compressor, the problem is that the compressor will not pressurize over about 85 psi..where would be the best place to start troubleshooting?..BTW, there is

The usual problem with oil-less type compressor is the Teflon compression ring and cylinder will fail causing the problem that you describe. Easy to check. With cover removed, turn the pump until the piston is all the way up. With good light, check the condition of the cylinder near the top. If the cylinder looks scratched, air is leaking past cylinder and ring and pressure will not build up enough to reach cut-out. If cylinder looks smooth, then problem is head valve reeds or head gaskets. Indication of bad reeds or head gasket blown, is extremely hot head during fill cycle. Good luck

Piston ring for campbell WL506206AI

Most parts lists only show the motor/pump assy (WL373000AJ) for your compressor. Campbell-Hausfeld does however have a breakdown of the motor assy and shows the piston/cylinder assy (WL210300SJ) being available for your compressor. It would be available from any C-H repair center or online at sites like That is the only way the piston, piston ring and cylinder parts are available, you cannot buy just the piston ring even though that's the main fail part in this assembly.

I just put a repair kit in my sx150 stapler and it fires put will not recoil i think im missing a spring in the bottom of the piston cylinder?

The Bostitch SX150 pneumatic brad nailer/stapler uses air to both drive the brad or staple and to return the driver/piston assembly to the top of the gun for the next firing. There is no spring that goes into the sleeve or under the piston. If your driver is not returning to the top of the gun you may have put an o-ring or seal in the wrong place or left one out. The o-rings and check seal on the bottom half of the driver sleeve are what control the air that returns the piston to the top so check those first.

I have a Campbell Hausfeld commercial air comprssor that has a moisture filter but I get a lot of oil in the hose which gets all over my air tools and clogs up my media blaster. What's going on an

If you are getting oil from the air pump in your hoses and tools your problem is in the cylinder/piston area. The piston on air pumps is very much like a car piston, depending on what model you have it has compression rings and oil scraper rings. If any of these are damaged or if your cylinder(s) is badly scored oil will get by the piston and be forced out with the compressed air to your tools. The only repair is to take the head and valve plate off and find out what parts you need to replace. If the cylinders are lightly scored they can be honed out but you can't machine them out as Campbell Hausfeld doesn't make oversized rings or pistons.

How to remove crankshaft for campbell hausfeld compressor

I assume you have removed the valve head-valve plate-cylinder assembly from the base and pistons. Remove the four bolts holding the bearing cap assembly on one side of the crankcase and remove the cap. You have to pull on the crank to get the crank bearing out of the opposite side of the crankcase. Move the crank forward and turn it until the rear bearing will clear the crankcase and the whole thing will tilt and come out the top. Campbell sells the entire crank, con rods, pistons & rings as an assembly under part number VT040600AJ. This is the best way to go as they don't have con rods to go on the crank if you were to get the journals turned down. NOTE: During reassembly, the bottoms of the cylinders have a taper so you don't need a ring compressor to get the pistons in the cylinders. Just be sure the oil rings are in properly before pushing the cylinder all the way down. The thin oil scrapper rings have a tendency to fold over and get caught between the piston and cylinder.

Try putting a hose clamp around the rings and gently tighten it then with the piston in the cylinder tap the piston easy with a rubber mallet. Make sure you oil the cylinder rings and piston.

Compressor runs but will not air up pass 10 psi

sounds like something has compromised the piston or rings. would advise you remove the cylinder head and inspect cylinder and bore, think you will no doubt find something broken.

Driving pin won't reset

The check valve is what causes the pin/driver to return to top of cylinder. To check if it is in place, remove the cylinder from the gun and look for an oring/band installed on a groove. This groove should have vent holes drilled thru the cyl. Holes should be clean. Any oring or rubber band can be used here. Just tight enough to stay in place. Other things to check:
Pin/driver should fit snuglly enough to hold it's own weight in cylinder. If your gun uses a plastic ring, it may be replaced with a rubber oring. Just make sure that the piston travels freely but holds its wieght.
There should be a bumper and a washer in the lower part of the gun. The bumper should not have any cuts or missing pieces and the washer should fit snuggly around the driver blade to prevent air from leaking down thru bottom of gun. If air is leaking down thru bottom, there is less pressure to push driver up. Email if you have more questions, good luck with your repair.
