Ordering by number: this is R085887, which also shows up as 3310103555, the Chicago Pneumatic cylinder bushing. The cylinder is the bore the piston runs in, and it sets the working clearance of the rock drill once the bore opens up, air bypasses the piston and blow energy drops.
You will find it on the diagram for the CP 0009 A F E CS ES AC Rock Drill and CP 9 9S Rock Drill. Pull up the diagram and confirm the reference number for your serial before ordering.
