Cylinder Set carries Atlas Copco part number 3121075580 and is stocked here under AC-3121075580. The cylinder is the bore the piston runs in, and it sets the working clearance of the pusher leg once the bore opens up, air bypasses the piston and blow energy drops.
You will find it on the diagram for the BBC 34W WS Pusher Leg Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
