Ordering by number: this is 9234001554, the Chicago Pneumatic piston ring – complete. The piston is the striking mass of the breaker; its condition sets impact energy, so scoring, mushrooming, or lost diameter shows up directly as reduced production.
Crowder’s breakdowns list this part on the Cobra Combi Gas Drill/Breaker and Red Hawk Gas Breaker/Drill. The complete machine is the Atlas Copco Cobra Combi Gas Paving Breaker/Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
