The Wacker Neuson Maintenance Kit is a genuine OEM service kit designed for the BH 55, BH 55rw, BH 55rw RS, and BH 65 series gasoline-powered demolition breakers. As a direct OEM replacement, this kit delivers the correct components to restore your breaker to peak operating condition, covering a wide range of tool-steel configurations including 27x80, 25x108, 28x152, 28x160, and 32x160 variants. Sourced directly from Wacker Neuson, every item in the kit meets the same build standards as the original parts installed at the factory. Having the right maintenance kit on hand means faster service intervals and less time pulling your breaker out of rotation.
Key Features
- Genuine OEM Components — Every part in this kit is manufactured to Wacker Neuson's original design tolerances, ensuring correct fit and function specific to BH-series gasoline breaker internals.
- Broad BH-Series Coverage — Fits the BH 55, BH 55rw, BH 55rw RS, and BH 65 series across multiple tool-steel configurations, making it a versatile service solution for mixed fleets.
- Drop-In Service Replacement — Designed as a complete kit so all wear items are serviced together in a single procedure, eliminating the need to source individual components separately.
- Sustains Full Impact Output — A properly maintained BH-series breaker delivers consistent blow energy for concrete demolition and breaking applications; worn internal components reduce strike force and can cause erratic cycling.
- Correct Kit for Your Tool Steel Size — Available across the full range of BH 55 and BH 65 hex and round shank configurations, so you get the right maintenance components matched to your specific breaker setup.
A maintenance kit for a gasoline-powered demolition breaker typically contains the consumable and wear items — such as seals, O-rings, and other service components — that degrade with normal operation. Replacing these parts at the manufacturer's recommended intervals keeps the breaker's internal pneumatic and mechanical systems sealed and functioning correctly, which directly affects blow energy and cycle rate. When these components are neglected or worn past service limits, performance drops noticeably and further internal damage can follow, turning a routine service into a costly repair.
