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


If you are trying to loosen or tighten a bolt or nut the the impact just stops more than likely there is a problem in the hammer (clutch) mechanism (items# 24 through 30), there could be broken part causing the mechanism to jam, the hammer (clutch) needs to hit and then slip to let the motor turn as they are directly coupled (no gears). On the flip side in the motor there are vanes (blades)
(item# 17) that need to have free movement and could also cause a condition were the motor could have low power or cause a locked condition.

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.

Mazda part numbers that should work N236-14-633A - N326-14-633

how much oil did you put in? you are only supposed to put a few drops in the air hose coupler.
