The Wacker Neuson Repair Kit WM80 Piston BH5/6X BS30 is a genuine OEM repair kit designed for the BH 65 and BH 55rw breaker series, as well as BS62-2 and BS68-2 rammer series machines. As a factory-sourced component, this kit delivers the exact specifications required to restore proper piston function and maintain the performance integrity of your Wacker Neuson equipment. Compatibility spans a wide range of configurations across both the BH and BS series, making the a versatile service solution for mixed fleets. Keep this kit on hand to minimize unplanned service interruptions during demanding breaker and rammer applications.
Key Features
- Genuine OEM Piston Sealing Integrity — Factory-sourced materials and tolerances ensure correct compression seal against the cylinder bore, critical for consistent impact energy delivery in breaker and rammer applications.
- Direct-Fit Replacement — Engineered to drop into BH 65 and BH 55rw breaker housings and BS62-2 and BS68-2 rammer cylinders without additional machining or fitment adjustment.
- Broad Model Coverage — A single kit covers multiple tool shank configurations across the BH 65 and BH 55rw breaker lines as well as the BS62-2 and BS68-2 rammer families, including Sunbelt variants.
- Restored Impact Performance — A worn or damaged piston assembly causes loss of striking force and erratic operation; this kit returns the piston to spec so your breaker or rammer delivers full, consistent blow energy.
- Genuine Wacker Neuson Parts Quality — Supplied directly through the Wacker Neuson OEM parts network, confirming part number 5100004116 is the correct, authorized service component for these machines.
The piston assembly in a breaker or rammer converts combustion or hydraulic energy into rapid, high-force reciprocating movement — it is the core mechanical driver behind every strike the machine delivers. Over time, piston rings and cylinder contact surfaces wear, leading to loss of compression, reduced impact force, and eventually complete failure to cycle. Replacing worn piston components with a correctly specified repair kit like the Wacker Neuson 5100004116 restores the compression ratio and stroke dynamics the machine was built around, bringing output back to full working specification.
