Up for sale is a Chicago Pneumatic CP KF135869 that fits the CP772 3/4” dr. and the industrial models as well. The used parts I have here aren’t questionable or may work as they will work! They are very serviceable parts and they are priced to make the repair feasible. This came from a slightly used tool. Look at the inside that’s the telltale sign. A couple of markings where the motor will slide but not burrs. I was trying to take pictures to represent that, but I don’t think the pictures do it any justice. Warm the housing and the motor will slide right in! Like new performance with used pricing. I sell only the tried and true replacement parts that work! Usually ships in 24 hours!
