The Wacker Neuson Starter is a genuine OEM component designed for the RD7 series tandem rollers and the DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H reversible vibratory plate compactors. Sourced directly from Wacker Neuson, part is manufactured to the same specification as the original unit fitted at the factory. This starter is compatible across a wide range of DPU model variants — including He, Heh, Heap, Hec, Hech, and regional US configurations — as well as multiple RD7H-ES and RD7Heh roller variants. If your machine is cranking slowly, failing to turn over, or the starter has seized or burned out, this is the correct direct-replacement part to restore full engine-start function.
Key Features
- Correct Engagement Geometry — Built to the exact pinion tooth count and drive engagement specification of the original, ensuring clean mesh with the ring gear on Wacker Neuson diesel engines across the DPU and RD7 families.
- Genuine OEM Quality — As a genuine Wacker Neuson part, 5000129926 delivers the correct amperage draw and torque output required to crank diesel engines in the DPU 4045H through DPU 5545H range under full compression load.
- Broad DPU and RD7 Fitment — Covers DPU 4045H, DPU 4545H (He, Heh, Hec, Hech, Heap variants), DPU 5045H, DPU 5545H, RD7H-ES, and RD7Heh series machines — one part number serving multiple platforms.
- Restores Reliable Engine Cranking — A failed or dragging starter prevents the machine from starting entirely, halting compaction operations. Installing a correctly specified replacement gets diesel-powered equipment back to work without secondary damage to the flywheel ring gear.
- Electrical Safety Compliance — As a primary engine-start component, using a correctly rated OEM starter prevents overload on the battery circuit and eliminates the risk of wiring damage or fire associated with undersized or mismatched units.
The starter is an electric motor that cranks the engine during startup by engaging a small drive gear (the pinion) with the engine's flywheel ring gear. When the ignition is activated, the starter solenoid energizes the motor and pushes the pinion into mesh with the ring gear, spinning the engine fast enough to achieve compression ignition — critical on diesel-powered equipment like the DPU reversible plate compactors and RD7 tandem rollers. When a starter begins to fail, symptoms include slow cranking, grinding noises, or complete failure to turn the engine over; left unaddressed, a failing starter can damage the flywheel ring gear, turning a straightforward part swap into a far more involved repair.
