This is the Tamco/Toku back head bolt part number 410201500 (also carried as 400201500), Crowder SKU TK-410201500. The back head closes the top of the breaker and carries the air inlet and control gear, so damage here usually shows up as a leak at the handle rather than lost power.
It is called out in the parts diagram for the TPB 30 Paving Breaker and TPB 40 Paving Breaker. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the full diagram library; complete tools are on the Tamco/Toku lineup. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
