Upper Valve Lid is the Chicago Pneumatic service part carried under part number R138096 (also carried as 3310104416). It directs the flow that reverses the piston in the breaker. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
It is called out in the parts diagram for the CP 1210 S SVR Paving Breaker and CP 1210 1210S 1210SVR Paving Breaker. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
