The Wacker Neuson is a genuine OEM Tappet Adjustment Screw designed for the BS-4As series vibratory rammers and VP1030A / WP1030A single-direction vibratory plate compactors. As a factory-sourced component, part is manufactured to the exact tolerances required for correct valve clearance across the full range of compatible machines. This screw fits a wide spread of BS rammer variants — including the BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, and BS72-4As — as well as the VP1030A and VP1030Aw plate compactors. Ordering the correct OEM part protects engine performance and ensures your valve train adjustments hold true over time.
Key Features
- Exact OEM Thread Specification — Manufactured to Wacker Neuson's precise thread pitch and hardness spec so the screw seats and locks correctly in the tappet adjuster without stripping or backing out under vibration.
- Broad BS-4As Rammer Compatibility — Confirmed fitment across the BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, and BS72-4As vibratory rammer family, covering both standard and high-altitude variants.
- Fits VP1030A and WP1030A Vibratory Plates — Also confirmed for the VP1030A, VP1030Aw, and WP1030A single-direction plate compactor lineup, making this a versatile service part across two equipment families.
- Valve Clearance Integrity — Correct tappet adjustment is critical to engine compression and power delivery; a worn or damaged adjustment screw leads to improper valve clearance, rough running, and accelerated valve train wear.
- Genuine OEM Sourcing — Sourced directly from Wacker Neuson, this part carries the same quality controls as the original component installed at the factory, with no guesswork on fitment or material grade.
The tappet adjustment screw is a small but critical engine component that sets and holds the valve clearance between the rocker arm and the valve stem. On four-stroke engines like those found in the BS-4As rammer series and VP/WP1030A plate compactors, correct valve clearance directly affects compression, fuel efficiency, and consistent engine starting. When this screw wears, strips, or loses its ability to hold adjustment, valve clearance drifts out of specification — causing hard starting, power loss, increased engine noise, and potential long-term damage to the valve train. Replacing a faulty tappet adjustment screw restores proper engine tune and protects the surrounding components from premature wear.
