Up for sale is an equivalent CP (Chicago Pneumatic) CA131501 797 A K / B L 1” Dr. Tune Up Kit WITHOUT BEARINGS. The new parts are OEM IR or CP from either IR or CP or from an IR or CP manufacturing contractor. These parts with proper ordering are guaranteed to fit and work. Most kits from CP do not include bearings and are purchased at an additional cost. I offer this kit with bearings as well. This quality kit fits Chicago Pneumatic model CP797 A K / B L - 1 ” dr. impact wrench. A quality kit that works! These kits have all the ‘soft parts’ for the throttle and air motor (also includes motor bearings) and a socket retainer and oring for the shank . This kit has phenolic blades to replace the OEM blades. Some signs of needing a rebuild would be the obvious loss of power or that persistent air leak. This kit will put your gun back at the top of your shop! Warranty would only apply to proper install of parts! Usually ships in 24 hours!
