I have a CP -828 speed ratchet in good shape. It has 3 three small throttle pieces that need to be replaced. An O ring part #A082777, a small spring part #KF124390 and a small valve part #KF125190. These parts are easily found online.
I am giving this Air Ratchet away. I am not likely to use this tool in the future.
Please call me at the phone number show contact info
if you want more information.
