Ordering by number: this is 131301010, the Tamco/Toku spring washer. It loads its mating part against the seat. When free length drops, the symptom is inconsistent operation the tool works, but not crisply.
It is called out in the parts diagram for the TJ 15 Rock Drill (RD 30) and TJ 20 Rock Drill (RD 40). That machine is the Tamco/Toku TJ-15 Rock Drill if you are pricing a replacement rather than a repair. Check it against the reference number on the diagram first; serial breaks change what fits.
Work through the rest of the assembly on the same breakdown, or start over from the parts breakdown index. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
