The Wacker Neuson 5100023865 is a genuine OEM Locking Tappet designed for the RC50 and RC70 series single-drum soil compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It fits a broad range of RC-family variants including the RC50, RC50p, RC70, RC70p, RC70vo, and their corresponding US-market models. Keeping this component in proper working order is essential to maintaining correct valve timing and engine performance across the RC compactor lineup.
Key Features
- Genuine OEM Precision Tolerancing — Manufactured to Wacker Neuson's exact dimensional and hardness specifications, ensuring the tappet maintains consistent contact geometry within the valve train assembly.
- Direct Drop-In Replacement — Engineered to seat and lock exactly as the original, with no rework or adaptation needed during installation.
- Broad RC-Family Fitment — Confirmed for RC50, RC50p, RC70, RC70p, and RC70vo variants, including US-market configurations, covering both smooth-drum and padfoot models.
- Valve Train Stability — A correctly functioning locking tappet holds valve adjustment precisely, supporting consistent compression and clean combustion cycles — critical for a machine working under sustained compaction loads.
- Verified Part Number — Part number 5100023865 is cross-referenced across all listed RC50 and RC70 build codes, giving you confidence you are ordering the right component for your machine.
A locking tappet is a mechanical valve train component that sets and holds the clearance between the rocker arm and the valve stem. In a single-drum soil compactor like the RC50 or RC70, the engine is subjected to continuous vibration and load cycling, which places sustained stress on all valve train components. If the locking tappet wears or loosens, valve clearance drifts out of specification — leading to reduced compression, rough running, increased fuel consumption, and accelerated wear on surrounding engine components. Replacing a worn tappet promptly restores correct valve operation and protects the engine from further damage.
