Compressor does not build up pressure

I have a model # 919.167320 air compressor, that runs very well it just does not pump the air into the tank, and no there are no leaks. The pump # is D27348. Could you tell me what part number I would need to fix this problem, or is there a valve, o ring, gasket, etc. etc. rebuild kit for that pump. Thanks,

SOURCE: Not building pressure into tank

If it's a newer model the parts are surprisingly inexpensive in some cases. Locate the parts and you may be surprised, I know I was a few times replacing whole piston assembly for almost just a few bucks and so quick and hassle free. And that fixed the no air into the tank issue I had on the job back up and running in an hour counting going to get parts.If it's oill free that's what I had, very inexpensive and easy just replace the piston assemblies undo the rod and it should drop right out the bottom.

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

SOURCE: wont build pressure over 25 psi after rebuild

cagey here i took mine in to be fixed and it was the piston and rings. they couldn't hold over 33psi of pressure.

SOURCE: Was working normal suddenly will not build pressure

Maurader1 an apprentice has this problem solved and is spot on. All these gurus and wiz need to stick to the basic and common sense. The first place your pump will give out after use or abuse is the gasket. All this garbage about defective reeds and defective pressure switch is a lot of nonesense if you first don't rule out the most common problem the head gasket. I'm cheap and this thing has paid for itself 10 time over. You can get a gasket kit for $7, but I fabricated a gasket out of the back of my notebook and sprayed some gasket spray and been working like a charm ever since.

Charge air pro model ir330e20 builds pressure to only 60 psi and will not stop running


Cbillgreene:

Your compressor is leaking air somewhere between the compressor head and the tank. With the compressor running, feel carefully around the ends of the tube that leads from the compressor head to the air tank. You will probably feel some air leaking around one end or the other. If so... remove the tube and find out which packing has failed.

I have a porter cable compressor, but the pump won't shut off, and the pressure won't build it


Hi

Here are a few things to check, you may have already checked some of these.

*Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.

*Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
*Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.
*Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.
*Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.
*Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
A worn cylinder will also contribute to the problem of pressure build-up.
*Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.

Cf2600 won't build pure pressure. Could air intake be stopped up. Had dirt dobber stop up on older compressor. Where is air intake. Can't locate.


No there is not a filter. Since the pump is enclosed in the plastic covers there would not be a way to service it. Now if it is not building any pressure then it could be a few things. First would be the drive belt. (item 125) If it breaks then it won't pump at all. Also if the air hose that exits the pump (item 122) gets a hole in it then it won't fill the tank. A worn head valve plate (item 106), blown gasket (item 105), or a worn piston and sleeve (items 109 and 112-2) can also cause this. If the check valve into the tank (item 16) gets stuck open it too will limit how much the compressor will pump BUT usually it will build up some pressure then just keep running without building any higher pressure into the tank.

Here is a parts diagram so you can see where the belt and other parts are located plus it contains all of the part numbers.

I have a craftsman dual tank air compressor and it only builds up pressure to 20 psi. I have checked the valve reeds and they are not cracked or broken. I can't feel any leaks while it is running. ...


Were 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.

My Craftsman air compressor has wored fine till now. It does not want to build up pressure beyond 50 psi.yes I did check the drain valve and no leaks. Motor seems to be putting out the rpm's and the oil...


Check for a leak between you compressor head (pump) and your tank. Your pump output may be good but as your tank pressure gets higher the leak will not allow the tank to build up.

Air compressor fills, but slows down as the pressure builds


sounds like you need a new check valve which should be somewhere between the compressor outlet piping,tubing,etc and the tank which prevents the air in tank to back feed to the compressor which would cause hard starting and could damage the motor easy way to check is when you shut off the compressor with some air in the tank if the check valve is bad it would continue to bleed air out out the unloader valve .the unloader valve on your unit is most likely part of the pressure switch when the unit shuts of it should only bleed down the pressure in the pump so it would make it easy to start when needed hope i didn't confuse you

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.
