Wacker Neuson 5000098449 Inlet Rocker Arm

The Wacker Neuson is a genuine OEM Inlet Rocker Arm designed for the RD7 and RD10 tandem rollers and the DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555H series reversible vibratory plate compactors. As a direct OEM component sourced through Wacker Neuson's authorized parts network, the meets the original engineering tolerances specified for these engines, ensuring it seats and pivots correctly against the valve train without adjustment. This part covers an exceptionally wide range of configurations across both the RD tandem roller family and the diesel-powered DPU compactor lineup, making it a go-to valve train replacement for mixed fleets. Verifying your machine number against the fitment list before ordering is recommended, as multiple configuration variants exist across these model series.

Key Features

• OEM Valve Train Tolerances — Manufactured to the original pivot geometry and contact-surface specifications, ensuring correct lobe-to-rocker contact and consistent valve lift across the engine's service life.
• Drop-In Engine Replacement — Engineered to install directly onto the existing rocker shaft and align with the OEM valve stem without shimming or custom fitting.
• Broad Fleet Coverage — Fits RD7 and RD10 walk-behind tandem rollers and a wide range of DPU 4045H through DPU 6555H diesel reversible vibratory plate compactors, spanning numerous regional and configuration variants.
• Protects Valve Timing Integrity — A worn or damaged inlet rocker arm causes inconsistent valve opening, leading to loss of compression, rough running, hard starts, and accelerated engine wear; replacing it restores correct timing and combustion efficiency.
• Genuine Wacker Neuson OEM Part — Supplied as an authentic component through Wacker Neuson's authorized parts network, backed by the manufacturer's part number for confident identification and sourcing.

The inlet rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft lobe — via the pushrod — to the intake valve, opening it at precisely the right moment to allow the air-fuel mixture into the combustion chamber. In diesel-powered equipment like the DPU compactors and RD tandem rollers, correct rocker arm geometry is critical to maintaining proper valve lift and timing, which directly affects compression, fuel efficiency, and smooth operation. When the rocker arm wears at its pivot point or contact surfaces, valve lift becomes inconsistent, resulting in rough idling, reduced power output, difficult starting, and — if left unaddressed — potential damage to the valve stem and camshaft.
