The Wacker Neuson Tappet is a genuine OEM component designed for PT6LT and PT6LS series trash pumps, RT560 and RT820 series vibratory trench rollers, and DPU 9070 and DPU 100-70 reversible vibratory plates. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring correct clearance and seating within the valvetrain. This Tappet fits an unusually broad range of Wacker Neuson engine-powered equipment, so always confirm your model number before ordering.
Key Features
- Genuine OEM Valvetrain Precision — Manufactured to Wacker Neuson's original tolerances, ensuring proper valve lift, consistent contact geometry, and correct oil film retention across the tappet face.
- Drop-In Engine Replacement — Seats directly into the existing bore with no machining or shimming required, maintaining the designed valve-to-cam relationship on the original engine assembly.
- Wide Equipment Compatibility — Confirmed fitment across PT6LT and PT6LS trash pumps, RT560, RT820, and RT820HT vibratory trench rollers, and DPU 9070 and DPU 100-70 reversible vibratory plates.
- Protects Camshaft and Valve Life — A correctly functioning tappet distributes load evenly across the cam lobe; a worn or pitted tappet accelerates camshaft wear and leads to rough running, loss of power, and valve timing drift.
- Sourced Direct from Wacker Neuson — Supplied as a genuine part under part number 5000063666, carrying the same part number used by authorized Wacker Neuson service dealers.
A tappet — also called a valve lifter — sits between the camshaft lobe and the valve stem or pushrod inside the engine. As the camshaft rotates, the tappet translates that rotational motion into the precise up-and-down movement needed to open and close each engine valve at the right moment. When a tappet wears, becomes pitted, or loses its correct profile, valve timing suffers, causing rough idling, reduced power output, increased fuel consumption, and accelerated wear on surrounding valvetrain components. Replacing a worn tappet promptly restores correct valve operation and protects the camshaft from further damage.
