This is Atlas Copco part number 3371814125 striking piston, stocked at Crowder Supply as AC-3371814125. It is the business end of the breaker it locates the tool steel and absorbs the impact reaction, so bore wear here shows up as a loose, rattling shank.
It appears on the MH 11 Hydraulic Paving Breaker and MDR 30T Hydraulic Post Driver, and on 7 other machines breakdown. 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 breakdown index. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
