Question about Garden

1 Answer

I have a Harbor Freight 2 HP, 8 Gal, hot dog style air compressor. The model # is 95386. It has only about 2 hours use. It has the proper amount of oil. It has worked well until just recently. Now, it compresses air, but it stops at 20 pounds of pressure. It doesn't turn off. The switch doesn't stop the unit. It just keeps running, but doesn't create any higher pressure than 20 pounds. I called Harbor Freight tech support. They said that it is probably the head gasket. I removed the head. The gaskets look perfect. I looked at the cylinder bore. No scuffing. The rings look fine on the piston. I reinstalled the head and torqued the four head bolts to 12 ft lbs each.

    Unfortunately, the head area is cooled by the fan on the motor. Consequently, I cannot turn off the cooling air even for a short time. I have felt around possible areas of leaking, but I cannot feel nor hear where the air is going.

If the air pressure will not go higher then 20 PSI and the compressor is still pumping air then it is going somewhere.... to find the leak I would feel for the escaping air... if you cannot feel it then take something like an old rope...light it on fire and then snuff it out so it will smoke... then hold that different places around the compressor while running to see where the air is coming out will see the smoke blow when you get near the leak...

Am out of oIL to put in a campbell hausfeld 20 gallon 4.5horsepower air compressor

Google the model number, download a copy of the owner's manual, follow directions. Try searching that model number at If the manual does not exist anymore, and the pump has a sight glass, fill with clean, non-detergent straight 30wt motor oil, available at most car parts stores. If there is no sight glass, drain what is in there and pour in 1/2 qt. No promises that is right, but it is likely close. Last option, go to a Harbor Freight store. Look for a compressor with a pump that looks like yours on size and shape. look at that manual and use that amount of oil. Good luck

I have central pneumatic 21 gal. air compressor. The unloader valve is broke. The power switch is a fenwai model: fw-10. Where can I buy a new unloader valve?

If you should mean the switch that is pressure controlled that turn the compressor on and off- that is a fairly universal replacement piece, As is the power switch itself

If you needed that specific part, your best bet is Harbor Freight tools who owns the Central Pneumatic domain.

The clutch on my air conditioner compressor went out. Can I tackle a fix by myself?

With the proper tools, a person can change the compressor clutch. Make sure you get the right clutch assembly and then it's a matter of getting the right tools to remove/install the clutch. I bought a set from Harbor Freight and it has served me well. I am not connected in any way to harbor freight and the same set of tools should be available form most any auto parts store.

30 weight non detergent. Sears has this oil on the shelf or you can get the same at any auto parts place.
