The Wacker Neuson Service Kit BH40 55-65 from V103 A.WM80C is a genuine OEM service kit designed for the BH40, BH55, BH65, and BH55rw series hydraulic breakers equipped with the WM80C engine, covering units from Version 103 onward. As a factory-sourced kit, the delivers every component to the correct Wacker Neuson specification, so you can complete a full service interval with confidence. Compatibility extends across a wide range of tool configurations within the BH series — including 27x80, 25x108, 28x152, 28x160, and 32x160 hex tool variants — making this a single-source solution for mixed fleet service. Keep the on the shelf and your BH breakers are covered when the next service interval arrives.
Key Features
- Genuine OEM Components Matched to Spec — Every wear item in this kit is sourced directly from Wacker Neuson, ensuring each seal, gasket, and consumable meets the exact tolerances required for the WM80C engine and BH breaker drive system.
- Covers BH Series from Version 103 Onward — Engineered specifically for BH40, BH55, BH65, BH55rw, and BH55rw RS models built from V103 up, so the contents align precisely with the internal components in those production versions.
- Wide Tool-Size Compatibility in One Kit — A single part number services multiple hex tool configurations (27x80, 25x108, 28x152, 28x160, and 32x160), cutting the number of SKUs you need to stock for a mixed BH fleet.
- Restores Full Breaker Output — Worn seals and degraded service components reduce impact energy and cycle rate; replacing them with this OEM kit brings the breaker back to its rated breaking force and consistent blow frequency.
- Prevents Unplanned Engine and Drive Failures — Completing scheduled service with the correct OEM kit protects the WM80C engine and hydraulic drive train from accelerated wear caused by degraded fluids, worn seals, or contaminated filters.
A service kit for a hydraulic breaker like the BH series bundles together the consumable and wear components — typically seals, O-rings, filters, and related gaskets — that must be replaced at set service intervals to keep the tool operating as intended. In the BH40, BH55, and BH65 range, the WM80C engine and hydraulic drive system rely on these components to maintain correct pressure, prevent contamination, and deliver consistent impact energy to the chisel. When these parts are left beyond their service life, sealing failure or contamination can cause rapid internal wear, loss of breaking power, and ultimately costly component damage that far exceeds the cost of routine service.
