The Wacker Neuson 5100023842 Locking Tappet is a genuine OEM component designed for the RC50 and RC70 series single-drum soil compactors. As a direct OEM replacement, this part is produced to the same specifications as the original, ensuring it installs correctly and functions as intended within the machine. Fitment spans the full RC50 and RC70 lineup, including RC50, RC50p, RC50p US, RC70, RC70p, RC70vo, and their DPF ROPS and DPF CAB variants. Sourcing the correct locking tappet by part number 5100023842 is the surest way to maintain the mechanical integrity of your compactor's valve train.
Key Features
- Genuine OEM Precision: — Manufactured to exact dimensional tolerances required for correct valve train engagement in RC-series compactors — no guesswork on fit or material spec.
- Drop-In Replacement: — Matches the original mounting geometry, allowing straightforward installation without modification to surrounding components.
- Broad RC-Series Coverage: — Compatible with RC50, RC50p, RC50p US, RC70, RC70p, RC70vo, and multiple DPF ROPS and DPF CAB configurations across the single-drum soil compactor lineup.
- Valve Train Stability: — A correctly seated locking tappet holds valve adjustment in position during high-vibration compactor operation; a worn or failed tappet can allow valve clearance to shift, leading to poor engine performance and accelerated wear.
- OEM Part Number Verified: — Order with confidence using Wacker Neuson part number 5100023842 to ensure you receive the correct component for your specific machine configuration.
A locking tappet is a small but critical component in an engine's valve train assembly. Its role is to secure the tappet or valve lifter in its adjusted position, preventing movement that would alter valve timing or clearance during operation. In the high-vibration environment of a single-drum soil compactor like the RC50 or RC70, maintaining consistent valve clearance is essential for smooth, efficient engine output. When a locking tappet wears, loosens, or fails, valve clearances can drift out of specification, resulting in symptoms such as rough running, reduced power, increased fuel consumption, or valve damage over time.
