I bought a Craftsman 1/2" impact wrench, model 875.198641 on ebay from the Sears store a couple of years ago. It was advertised to be "factory serviced". When I got it, it wouldn't turn very fast sometimes not at all, just dumps air out of the exhaust. I tried all 3 forward settings as well as reverse. I can hold the socket with my hand and stop the unit when it does turn. I'm using a 1/2" airhose and a large compressor. I took it apart, all parts look new, no dirt or wear. All parts are installed according to the parts illustration I found on the web. Any thoughts?
It's lubed well. The adjustable torque has 3 settings, the lowest setting won't turn the chuck at all, just dumps air out of the exhaust. When it's on the highest setting I can hold the socket and easily keep it from turning.It's lubed well.

I found these posts when looking for a repair kit or parts for my Sears
756 CP. Appears I need the fastest moving most common to fail NLA part. Had this gun since new. Used for years in the shop then
put it in the bottom of the tool box when the valve went out years ago.
In
a clean up round I pulled it out to make the decision fix or recycle.
One of those not wanting to throw out a perfectly good impact I started
looking for parts. I did order a valve from a 744 and will be trying it.
Since the shaft is shorter I was going to use the shaft from the 756
and cut it to make up the difference. Do not know yet if this will work.
In the mean time I started
looking through one of the spare hardware drawers and came across a oil
metering valve seat from a rotary engine. It fits rather snugly on the actuator
shaft from the 756 and with a washer works. It is basically a jet encased in rubber.
This
756 is back up and impacting well. So if any one is still looking for the
throttle valve for your 756 I can provide you with something that will
work. Do not know what the life expectancy will be though. Since this
will not be the everyday gun should last for a while.

I just bought one of these also. Manual says oil goes into "the air inlet" which I'm thinking is where you attach the hose. That way the oil is sprayed throughout the interior of the gun once you run air through it.
Question for you: I can't get an impact socket onto this gun, almost seems like the square hole is too small. (yes, both are 1/2" drive). How do you get a socket on this stupid thing?
(man that sounds like I'm an idiot, but I've spent a half hour leaning all my body wight, wiggling, etc. and can't get a damn socket on)
If your local Sears store can't help you, try looking to see if you have a Snap-On, Corn-well, or Matco tool distributor in your area. Many air tools are manufactured by companies who make tools for different distributors. I work in a shop, and have found that many of the tool trucks have parts that'll work on other brands of tools besides their own.
