20 Most Recent Craftsman 1/2" Impact Wrench - Page 4 Questions & Answers


I've been working on air compressors for a while now and so far haven't found any that give a specific amount of oil to put in the air pump crank case. They all have one of two methods to get the oil to the proper level. First, and my favorite, is a sight glass at the bottom of the crank case. About the size of a quarter, it lets you see how much oil is in the pump as you add it. Usually they have a red center dot which is where you want the oil level. A little over or under is OK but the sight glass should not be completely full or completely empty, both are hard on the pump and drive motor. Another method is a dip stick usually on the end of the fill hole cap. Only bad thing about these is you have to put in some oil, check the oil level with the dip stick, then add more oil and check it with the dip stick until you get to the full mark. Again, not over and only a little under is where you want the oil level.

Check all wring. Remove cove and see if you can turn over by hand.If you can't unit is broken/frozen.it should run on 120. look at the plug if prongs are vertical the unit 120vac. Look on motor wire box if it can be rewired it will be there. I doubt this unit is designed to operate on 120vax. The mots/pump assembly is not available for purchase. there are a few repair parts available. do you want to spend the time and money for rewind.? good luck

Could be piston O rings, worn cylinder line, worn reed valve-plate assembly, worn discharge check valve, leaking unloader valve. Need info if unloader is leaking or unloader tubing is leaking. The Cheapest and quickest is to remove valve plate assembly and inspect valve plate. Suction side should hold water and discharge valve should hold water placed on bottom of plate.

it is possible that it is not the compressor but the breaker has reached it's end of life. I'd change it to eliminate that before throwing any more parts at the compressor.
My suggestion anyway.

if you are using quick connects it is likely that you need to wrap with PTFE thread tape to ensure seal... If you aren't that would indicate a leak in the tool meaning the tool should be replaced...

At the back of the nail gun there is a cap and 4 screws. Take out the screws and you will find a diaphram, o-ring, and spring. The plastic housing that holds everything together could be cracked or the spring could be broken.

Only the motor needs its feed connections changed from one voltage to the other. Someone knowledgeable about motors should do this. But, not all motors have multiple voltage capabilities. I have a Craftsman 2 HP compressor myself that only will run on 220. Check your manual on this. If you can't change the motor, it will probably be cost-effective to run a 220 line over buying a new motor.
