Ordering by number: this is 1280582313, which replaced the older number 17639, the American Pneumatic Tool throttle valve spring. It is part of the operator control on the rock drill. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
You will find it on the diagram for the 109 Mini Rock Drill. The tool itself is the APT 109 Pneumatic Rock Drill. 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.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram hub. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
