The Wacker Neuson is a genuine OEM Inlet Rocker Arm designed for a wide range of Wacker Neuson reversible vibratory plates, single-direction vibratory plates, and the RS800H single drum vibratory roller. As a direct OEM replacement, part is manufactured to the same specifications as the original component, ensuring correct geometry, contact surface quality, and valve timing accuracy across the DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPS3050, and DPS3060 series, as well as the RS800H. This is a high-wear valvetrain component that should be replaced at the first sign of wear, pitting, or irregular engine behavior to protect the engine's long-term performance.
Key Features
- OEM Valvetrain Geometry — Cast and finished to the exact pivot radius and contact-pad profile of the original, preserving correct valve lift and timing across the engine's operating range.
- Drop-In Rocker Shaft Fit — Machined bore matches the OEM rocker shaft diameter so the arm seats and torques down without shimming or modification to the cylinder head assembly.
- Broad Fitment Across Plate and Roller Families — A single part number covers the DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPS3050, DPS3060, and RS800H, making it a practical stock item for fleets running multiple Wacker Neuson machines.
- Protects Intake Valve and Camshaft — A worn or pitted rocker arm contact surface causes uneven valve actuation, accelerating wear on both the intake valve stem and the camshaft lobe; replacing with a correctly profiled OEM arm stops this wear cycle.
- Fuel System Compliance — Correct inlet valve actuation is essential for proper air-fuel mixture and emission compliance; an OEM rocker arm maintains the intake event timing the engine was certified to operate within.
The inlet rocker arm is a pivoting lever in the engine's valvetrain that transfers motion from the camshaft lobe to the intake valve, pushing the valve open at the precise moment required for the intake stroke. It sits on a rocker shaft above the cylinder head and must maintain consistent contact with both the pushrod and the valve stem tip to deliver accurate valve lift. When the rocker arm wears at its contact surfaces or develops cracks at the pivot bore, valve timing deteriorates — leading to rough running, loss of compression, hard starting, and in severe cases, valve or camshaft damage that turns a simple rocker replacement into a costly engine rebuild.
