Think I already answered this for a Craftsman 1.5 pancake, or was referred to as horizontal, was that you ? If not then put in a search for your brand and hp and type of compressor and go to the web page for it and scroll down looking for the owners manual which will have an exploded view of the compressor dissasembled for parts identification but you should be able to see what you need to know. It's probably an Adobe file download.

Air compressor model no. 921.153101 blowing air trough air cleaner


If you get air movement out of the air cleaner and it only compresses air to 25psi, you have bent or broken reed valves in the head. Take the head off the cylinder and inspect the valve plates and reed valves. This is a Craftsman compressor so you'll most likely have to get parts through Sears at www.searspartsdirect.com. For best results replace everything between the head and cylinder; gaskets, valve plates and reed valves.

Compressor sucks air in through the outlet quick connect where the hose attaches. won't build pressure.


I have seen this condition many times. Usually, the comperssor head was removed for cleaning or repair and the valve plate was assembled incorrectly. Easy fix. Remove the head and flip the valve plate. Make sure that other components are correct. Examine plate for warping, gaskets for signs of leaking. Make sure that the motor is turning in the correct direction (fan blades on compressor pulley blowing air towards pump). Finally, take a look at the intank check valve. The valve will allow air into the tank and not let it flow back to the pump. In your case the valve must be faulty because because air was flowing from quick connect to pump. Good luck

Compressor goes to 35 psi wont fill anymore


There are a number of possibilities. The head on the compressor pumps usually uses some type of reed valves to separate the intake and exhaust sides. You can remove the top bolts (usually 4 bolts) that hold the head on and inspect the valve plate(s). Are the reed valves (usually just small metal strips) broken or not seating on their plates. Are the gaskets in fine shape? If you get a tear in the middle of the head or valve plate gasket, where it separates the intake and exhaust, then the pump will only build up pressure to the range you have or sometimes up to only the 50psi range.

Another thing to check is if it has a one way check valve that goes into the tank where the pump line/hose feeds from the compressor pump into the tank. Many of the check valves use a simple plastic cup and a spring. If they get stuck open then that will also make it not build up pressure.

The other part I can think of is the control box but usually when they fail they either won't turn on the unit or they will leak air.

The last thing to check would be the piston ring(s) and cylinder/sleeve. The oil less compressors will wear these items out far more often then an oil style will. When the oil less piston and sleeve get scored up (from dirt ingestion) then they also will not build up much pressure.

What goes in the small hole on the top of the main compressor cylinder on a 2340L5? Air is escaping and it will not pressurize the tank.


There should be a small bolt in the top center of the head. If the bolt is missing you will need to remove the head only and inspect the valves and valve plate. This bolt screws into the valve plate and holds the assembly together. The bolt may have just broke or the threads in the valve plate stripped out.In either case they need to be replaced!

Air compressor pumps to 25 pis thats it


I would say that you have a broken valve in the cylinder head, drain what pressure you have in it, with it unhooked and remove the cylinder head. there are reed type valve on a plate, the valves on the intake side open towards the cylinder and the discharge valves open towards the head. look for broken reeds or hung open with crud. also look to see if the gaskets are blown between intake and discharge side of the head, also if head gasket is intact between cylinder bores. These are the likely problems with these pumps, hope this helps!

The pressure will not build up


Remove the air from the compressor using the drain valve.
Remove the discharge hose. The one that goes from the pump to the tank.
Remove the air filter (and check condition)
switch the compressor on an with your hand, partially cover the air intake where the air filter bolts on(be carfull not to fully cover it).
You should feel the pump drawing air in.
If it dosn't draw you have a broken/leaking valve or a blown cross-over gasket if it is of the type with a split valve plate.
You'd need to remove the head/valves/plate to confirm this.

If it did draw in air,
Stop the compressor & re-fit the discharge hose.
Now run for a few seconds and check the draw again.
If its suction reduces you also have a valve/plate/cross-over gasket problem.

If it draws fine.

stop the compressor and loosen the discharge hose at the tank end.
You may hear a short air leak at first, but you should not hear air contniously leaking.
If it continiously leaks air then the check valve in the tank is shot.
NOTE: NEVER remove this valve if the compressor has air in the tank/receiver.
This should locate your problem for you.

3gal craftsman horizontal compressor wont build pressure


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.

I have a husky compressor, model number y6010-wk. it builds pressure slow, and shuts down right away.


Problem: My compressor is not producing the air that it once did. It takes twice as long to pump up.
Solution:
1)Turn off your compressor or disconnect the power.
2)Remove the connector tube that sends air to the tank.
3)Remove the head bolts on top of the pump.
4)Remove the head off of your pump.
5)Remove the valve plate off of your pump. It may be a one piece or a 2 piece design.
6)Inspect the valve plate for broken reed valves or broken gaskets above or below the valve plate.
