Question about Air Tools & Compressors
I have a Sears Craftsman 919.167312 My air compressor will not hold air. It leaks out of the bottom valve screw. I am thinking the screw is just worn out. I used to be able to seal air flow with only hand tight twists. Now I need vise grips and I have to turn and turn and turn. It is listed as #24 on the parts schematic.. I am thinking I not only need to replace the screw (which I'm sure is bad) but I also need to replace the part it screws into... But I do not see that listed..?? Opinion?

I have a 2hp craftsman air compessor with a two cylinder pump, Here is the info from my manual as far as oil capacitity:
Remove oil fill plug and slowly add
a compressor oil until it is even with the
top of the oil fill hole. NOTE: Do not
allow oil to be lower than 3/8"
from the top at any time. When filling
the crankcase, the oil flows very slowly
into the pump. If the oil is added too
quickly, it will overflow and appear to
be full. NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.
I buy my compessor oil from Lowes in the tool department. It comes in 16oz and sells for about $3. I wouldnt worry about how many ounces it holds but rather that the oil level is to top of filler hole. Lowes also sells a synthetic oil for about $7 and is recommended for severe conditions (hot / cold / used all day). Good Luck!

It's just too hot. Blow out the radiator weekly. There is an oil temp switch that might need replaced but the radiator is the most common problem with screw compressors. You can check the settings in the control panel, where you turn it on and off. It should be set for a high temp of 185°.

remove the drain plug. go to any auto parts store and tell them you need a drain ****.put it in and that should solve your problem. cost should be 2-3 dollars.

Unloader valve probably needs to be adjusted. Should be two jam nuts holding the unloader to the pressure switch. Loosen the jam nuts and adjust the unloader slightly away from the lever. Tighten the jam nuts and try it again.
