Ordering by number: this is 1280583003, which replaced the older number 18676, the American Pneumatic Tool cylinder Ass’y – 3″ hex. This is the main pressure housing of the chipping hammer. Because it wears against the piston, the two are normally inspected and replaced as a pair.
You will find it on the diagram for the 260 Chipping Hammer Series and M43 M44 4-Bolt Chipping Hammer. Check it against the reference number on the diagram first; serial breaks change what fits.
