The Wacker Neuson Tappet is a genuine OEM component designed for WP1550RW and WP1550R vibratory plate compactors and PT2R centrifugal trash pumps. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring correct fit and function without modification. Cross-platform fitment across the WP1550 plate compactor series and the PT2R pump line makes this tappet a practical stocking part for mixed Wacker Neuson fleets. Verify your model and machine number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Dimensional Accuracy — Machined to the exact profile and hardness specification of the original, ensuring correct valve train geometry and consistent lift across its service life.
- Drop-In Replacement — Seats directly into the engine block without reworking the bore or adjusting valve clearance beyond standard service procedure.
- Cross-Platform Fitment — Compatible with WP1550RW and WP1550R vibratory plate compactors and PT2R centrifugal trash pumps, covering multiple machines in the Wacker Neuson lineup.
- Protects Valve Train Integrity — A worn or pitted tappet causes uneven valve lift, leading to loss of compression, rough running, and accelerated camshaft wear; replacing it on schedule preserves engine performance.
- Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, backed by OEM part number 5000084331 for confident reordering.
A tappet — also called a valve lifter — sits between the camshaft and the valve stem in a small engine's valve train. As the camshaft lobe rotates, the tappet transfers that motion upward to open and close the intake and exhaust valves at precisely the right moment. When a tappet wears flat, develops pitting, or loses its hardened surface, valve timing becomes erratic, compression drops, and the engine runs rough or loses power under load. Replacing a worn tappet restores correct valve operation and prevents secondary damage to the camshaft lobes it contacts.
