The Wacker Neuson Starter Complete is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem ride-on rollers. Sourced directly from Wacker Neuson, this starter assembly carries the same specifications as the part originally installed at the factory, ensuring a straight swap with no guesswork on fitment. Compatibility spans the full RD27 lineup, including Pro, Basic, and T4F-compliant variants across both the RD27-100 and RD27-120 model families. When your roller won't crank, getting the right starter in fast is the priority — is the correct part for the job.
Key Features
- OEM Electrical Integrity — Genuine Wacker Neuson construction means correct voltage draw, torque output, and terminal configuration matched to the RD27 electrical system.
- Direct Bolt-In Replacement — Mounts to the engine block using the same bolt pattern and engagement geometry as the original, so installation follows the standard service procedure.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across Pro, Basic, and T4F variants, covering a wide range of machine serial configurations.
- Restores Full Cranking Power — A worn or failed starter leaves the machine unable to start on site; this assembly brings the engine cranking system back to full operational spec.
- Ignition System Safety Compliance — As a genuine OEM electrical component, 5200017642 meets Wacker Neuson's original design requirements for safe and consistent engine engagement on emissions-compliant T4F machines.
The starter is the electric motor responsible for spinning the engine over fast enough to initiate combustion and get the machine running. On a ride-on roller like the RD27 series, reliable starts are essential — a sluggish or failed starter can mean a machine that won't fire up at the beginning of a shift or after a shutdown mid-pour. When a starter fails, symptoms typically include a clicking sound with no crank, slow or labored engine turnover, or no response at all when the key is turned; replacing the complete assembly rather than attempting individual component repair is the standard and most dependable fix.
