Spring is the American Pneumatic Tool service part carried under part number 1280582782, which replaced the older number 00598. Springs in a breaker fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It shows up in the parts breakdown for the 140 Paving Breaker and 140 Paving Breaker – Former Construction. The tool itself is the APT 140 Pneumatic Paving Breaker. Pull up the diagram and confirm the reference number for your serial before ordering.
Everything else on that machine is one page away, and the full diagram library indexes every breakdown we publish. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
