O-ring is the Tamco/Toku service part carried under part number 131111356. Its job is to hold the pressure boundary between two mating faces; a hardened or nicked seal shows up as lost power and a damp housing well before anything else fails.
It appears on the TPB 40 Paving Breaker breakdown. That machine is the Tamco/Toku TPB-40 Paving Breaker if you are pricing a replacement rather than a repair. 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.
