The Wacker Neuson Return Spring is a genuine OEM component designed for BH55, BH65, and BH40 series breakers, as well as BS62 and BS68 series rammers. As a direct Wacker Neuson OEM part, it is manufactured to the same specification as the original, ensuring a correct drop-in installation with no guesswork on compatibility. This spring is confirmed to fit an extensive range of models across the BH and BS series lineups, including Sunbelt-designated variants. Keep part number on hand as a service spare to stay ahead of wear-related stoppages during demanding demolition or compaction work.
Key Features
- OEM Spring Tension Spec: — Manufactured to the original tension and length specification, so the return stroke force matches exactly what the machine was engineered to deliver.
- Direct Drop-In Installation: — Matches the original mounting points and hook geometry for a straightforward swap during routine service or breakdown repair.
- Broad Series Fitment: — Covers BH40, BH55, BH65 breaker series and BS62, BS68 rammer series, including standard, petrol, rs, lb, and Sunbelt-designated variants.
- Restored Return Stroke Performance: — A correctly tensioned return spring ensures the tool shank or piston cycles back fully and consistently, maintaining strike rhythm and impact output.
- Wear-Item Readiness: — Springs are a known wear item in high-cycle breaker and rammer applications; stocking part 5100065737 as a service spare keeps scheduled maintenance on track.
The return spring in a breaker or rammer is responsible for pulling the internal striking mechanism back to its ready position after each impact cycle. Without adequate spring tension, the tool loses its consistent strike rhythm — resulting in reduced impact energy, irregular cycling, or the mechanism failing to reset entirely. Over time, metal fatigue from repeated compression and extension causes the spring to weaken or break, making it one of the more routine replacement items in high-use demolition and compaction equipment.
