The Wacker Neuson Rocker Arm Complete is a genuine OEM component designed for DPU80 and DPU90 series reversible and standard plate compactors, including the DPU80Lec770, DPU80Lec670, DPU90Lec670, DPU90Lec770, DPU80Lem770, DPU80Lem670, DPU90Lem770, DPU80rLec670, DPU80rLec770, DPU80rLem670, DPU80rLem770, and DPU90rLem770 models. As a genuine Wacker Neuson part, the is manufactured to the same specifications as the original component installed at the factory, ensuring a direct, hassle-free replacement. Sourced directly through authorized Wacker Neuson supply channels, this assembly delivers the consistent valve train geometry and surface finish tolerances that keep your compactor running at full performance.
Key Features
- OEM Valve Train Precision — Manufactured to Wacker Neuson's original geometry and surface hardness specifications, ensuring correct rocker-to-valve contact and consistent valve lift across the engine's operating range.
- Drop-In Assembly Replacement — Supplied as a complete rocker arm assembly, allowing direct installation onto the existing rocker shaft without sourcing individual sub-components separately.
- Broad DPU80 and DPU90 Series Coverage — Confirmed fitment across multiple Lec and Lem variants in both standard and reversible (rLec / rLem) configurations, covering a wide span of the DPU80 and DPU90 model family.
- Restores Correct Valve Timing — A worn or damaged rocker arm causes improper valve actuation, leading to loss of compression, rough running, and hard starts. Replacing with part 5100026393 restores proper valve timing and engine efficiency.
- Genuine Wacker Neuson OEM Part — Backed by Wacker Neuson's OEM supply chain, this part carries the same part number — 5100026393 — used in the original machine assembly, so there is no ambiguity about what you are installing.
The rocker arm is a critical component of the engine's valve train, transferring motion from the camshaft — via the pushrod — to open and close the intake and exhaust valves at precisely the right moment in each combustion cycle. When the rocker arm is worn, cracked, or develops excessive play at its pivot point, valve timing becomes erratic, which shows up as rough idling, reduced power output, increased fuel consumption, and in severe cases, engine failure. Replacing a damaged rocker arm complete assembly promptly restores the valve actuation geometry the engine depends on for clean, efficient combustion cycle after cycle.
