Plunger Spring carries American Pneumatic Tool part number 1280583762, previously 02380 and is stocked here under APT2380. It supplies the return force for its assembly in the rock drill. A spring that has taken a set gives soft or sticky action long before it actually breaks.
It shows up in the parts breakdown for the 137 Rock Drill. The complete machine is the APT 137 Pneumatic Rock Drill. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
