This is the American Pneumatic Tool sleeve bushing Ass’y – 7/8 X 4-1/4″ hex part number 1280583604, which replaced the older number 09070, Crowder SKU APT9070. It is the sacrificial wear surface between two moving parts of the rock drill designed to be replaced so the housing around it is not.
The published breakdown lists it on the 155 Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the full diagram library; complete tools are on the American Pneumatic catalog. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
