Chicago Pneumatic CP CA149747 Repair Kit WITH 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 purchased at an additional cost. This quality kit fits Chicago Pneumatic model CP772H - 3/4” 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 new anvil, 2 hammer pins, cam release spring and steel ball . 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.
