Compressor shuts down and will not allow enough pressure run machine


Sounds like the oil is low or the cooler is dirty. If that's not the case then you have a defective thermal valve.

Compressor will run, but only builds to 20 lb pressure. Line to tank gets hot.


Very hot air is an indication of leaking /broken head gasket or reed valve. Before you remove any parts, with compressor running, check all fittings for leaks with soapy water. If no leaks, remove head and examine parts. If reed valve is broken replace as needed or do creative repair. Some valve plates have multiple reeds and only one reed is broken. Depending on your skill level, you can thread the hole and seal with piece of bolt (finished repair must not be any thicker than the plate). Good luck

I don't know anything about outboard motors, so I can't answer the reed valve question. There is a needle valve on the diaphragm side of the carburetor though. Maybe these two parts perform that operation.

Good Luck!

You have one or more valves broken in the head and need to be replaced, and Quincy compressors require a special tool to remove and install valves.

Honda 5.5 air compressor runs but does not build any air pressure to the tank?


In your cylinder head you have a broken reed or valve as some call them. I assume you have checked for a broken line or an open discharge valve? This is generally an easy fix and parts are mostly easy to obtain from your neighborhood NAPA.

Install reed valves hitachi air compressor need pics


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

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

Kicking overloads but not consistantly


First: Most all compessors use check valves at the tank and an unloader to allow the compressor to start without a load. Make sure that system is unloading and that check valve is not leaking causing head pressure at start. Second: Too frequent starts and stops will cause motor to overheat. Check Quincy manual for max starts per hour. enjoy

HOMELITE 330


The Homelite 330 has a set of "reed valves" (thin fiberglass flaps held in a V shaped holder, narro end of the V point to the engine) in between the carburetor and the intake port of the cylinder.

Looke here http://books.google.com/books?id=ISzSHyegUSYC&pg=PA218&lpg=PA217&ots=TiCmMmPbXi&dq=330+operators+manual+homelite#PPA218,M1

then look at part #26 on page 218.

basically it does:

Airflow Reed Valve engine
----> >

Their function is to open slightly when the air is rushing through them toward the engine, and yet flap closed again to stop the backflow or air/fuel from going out of the cylinder. The sucking action of the engine lets the air slightly move the reed off of the small part of the "V" and the air flows in. As the airflow is reduced the mechanical tension of the reed, trying to remain flat and not bent, closes it.

Since they are flaps there is a momentary time then the air will rush out as they close. But you not should see "lots" of fuel coming out of the carburetor.

Two symptoms will cause excess fuel/air rushing out of the carb.
1. if they are old the reeds can be slightly warped and just not seal against the reed valve cage. That means replacing the reeds (if servicable) or the reed valve (cage and reeds together).
2. If any dirt or sawdust ever got into the engine, there could be some particles stuck between the reed valve and the cage. This is usually near the top of the reed valve and once it's in there, it can't get out. You can sometimes tage out the reed valve cage, remove the reeds and clean everything. The foam seal around the perimeter if the black top cover of the Homelite 330 usually breaks down over time and lets dirt/fine sawdust into the "Clean side" of the air system. You should see no dirt/sawdust or debrea around the carburetor.

In either event you would want to make sure that when you are lookin at the part that the reeds are perfectly seated on the reed valve cage. If not, you get the symptoms that you described.

Good luck!
