This is Chicago Pneumatic part number C051781, which also shows up as 3310104868 cap screw, stocked at Crowder Supply as CP-C051781. This blanks off a passage in the housing. Thread and seal condition are what matter, and it is normally renewed when the housing is opened.
It is called out in the parts diagram for the CP 0014 RR RRBS Rock Drill and CP 4121 Chipping Hammer, and on 1 other machine. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
