Craftman impact wrench 1/2 inch model number 756188900
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.
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.
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.
Mazda part numbers that should work N236-14-633A - N326-14-633

Craftsman 1/2 inch air impact
- There are no chucks with these newer impact wrenches. See that little ring on the tip of the socket shaft? That is a lock ring and that is what holds your sockets in place. You will want to keep a few 1/2 impact wrench lock rings around. There is a tool they make to aid in removing and replacing those rings but it is not necessary. You can use a small flathead screwdriver and walk the old one off and the same for replacing it. All you need to do is snap a socket on there real good and let'er rip.

there are four settings on the air impact
if you dont use hand tools often you should never trust the torque from impact wrench you should always recheck with tension wrench for correct torque specs
or at least hand tools such as breaker bar, spanner, ratchet
depending on what your doing up and diameter of bolt or studd for what application

Dont know where to put oil in Craftsman 1/2 " Impact wrench
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)

Craftsman 1/2 inch impact wrench,not working
Make sure you have at least 90 pounds of air and if you do you need to oil the wrench air tool oil pour some in the where the air line hooks up ..air tools need to be oiled daily cause compressed air cause water vapors to build up when you use it and then when it sits it begins to rust a bit and the oil stops this ...

I get no movement on the socket just air blowing
The air motor is probably shot. Turn the socket a few revolutions by hand, and see if it frees up and starts working. A couple of firm raps on the workbench might help. Otherwise take it apart and see whats up. You'll probably find worn vanes or a vane stuck in the rotor. There will be several vanes, and they must slide in and out of the rotor easily. If you arte lucky you'll just have to clean out, lubricate, and reassemble.
