The Wacker Neuson Tappet is a genuine OEM component designed for RD7Ye tandem rollers, DPU4045Yeh vibratory plates, and the broader DPU40/45Yeh compactor series. As a direct OEM replacement, this tappet is produced to the same specifications as the original part, ensuring it installs and functions exactly as intended in your machine. Fitment extends across a wide range of Wacker Neuson walk-behind rollers and vibratory plate compactors, including LRC, HRC, EU, and US variants. When you match part number to your model, you can order with confidence knowing the fit is correct.
Key Features
- OEM Valve Train Tolerancing — Manufactured to the same dimensional and hardness specifications as the original, ensuring correct lift height and contact surface integrity for consistent valve actuation.
- Drop-In Engine Replacement — Engineered to seat and align exactly as the factory tappet does, requiring no machining or fitment adjustment during installation.
- Broad Model Coverage — Fits RD7Ye tandem rollers, DPU4045Yeh, DPU4045Yehzf, DPU45Yeh, DPU40Yeh, and RD10Yehf series machines across LRC, HRC, EU, and US configurations.
- Protects Valve and Camshaft Components — A correctly functioning tappet maintains proper valve timing and prevents accelerated wear on the camshaft lobes and valve stems, keeping the engine running at full power output.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this is not a substitute — it is the same part used in original equipment assembly.
A tappet — also known as a valve lifter — sits between the camshaft and the valve stem in a four-stroke engine, transferring the rotational motion of the camshaft into the linear motion that opens and closes the engine's intake and exhaust valves. It plays a direct role in maintaining correct valve timing, which determines how efficiently the engine breathes and generates power. When a tappet wears down or fails, valve timing becomes erratic, leading to loss of compression, rough running, increased fuel consumption, and potential damage to surrounding valve train components if left unaddressed.
