Back Head Bolt is the Tamco/Toku service part carried under part number Y10219110. The back head closes the top of the chipping hammer 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 appears on the THH 6 7 8 9 Chipping Hammer breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the parts breakdown index has the full breakdown library, and the Toku tool catalog covers the machines themselves. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
