Need throttle valve pin and throttle valve can not need something that is compatable to fix it
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.

if you have already used air tool oil you may have to take it apart and clean the motor vanes

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 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)
SOURCE: I have a husky impact wrench, set at 100psi, but
There should be an air control valve adjacent to the air inlet, is it opened sufficiently. Failing that there is a problem with the drive motor. It could be seized bearing or a broken vane. There is nothing you can really be doing wrong, it is a very straightforward tool.
