The Wacker Neuson is a genuine OEM Solenoid Coil designed for the RD24-100, RD27-120, RD27-120 C, RD28-120, and RD28-120 O Tandem Roller series. As a factory-sourced component, it is manufactured to the exact electrical specification required by Wacker Neuson's compaction equipment, ensuring correct coil resistance and reliable electromagnetic output. This Solenoid Coil covers an extensive range of RD series tandem rollers across multiple production generations, including US-market variants and the latest.3-series machines. Confirm your model number before ordering — fitment data for part spans over twenty distinct RD series configurations.
Key Features
- OEM-Spec Electrical Tolerance: — Wound and rated to the exact resistance and voltage specification Wacker Neuson requires, ensuring correct solenoid engagement without over- or under-actuation.
- Drop-In Coil Replacement: — Matches the original coil's bore diameter, terminal configuration, and mounting profile for a straightforward swap with no re-wiring or adapters needed.
- Broad RD Series Coverage: — Compatible with RD24-100, RD27-120, RD28-120, and their C (cab) and O (canopy) variants, including US-market models and current .3-series production units.
- Sustained Compaction Control: — A correctly functioning solenoid coil maintains consistent hydraulic or fuel-system valve actuation, keeping drum vibration and compaction output stable under continuous operating loads.
- Electrical Safety Compliance: — Genuine OEM construction ensures the coil meets Wacker Neuson's insulation and thermal ratings, reducing the risk of coil burnout, valve failure, or unintended machine shutdown on the job.
A solenoid coil is an electromagnetic component that generates a controlled magnetic field when energized, pulling a plunger or armature to open or close a valve within the machine's hydraulic or fuel system. On Wacker Neuson tandem rollers, this coil plays a direct role in regulating functions such as vibration control or engine fuel delivery, depending on the valve circuit it serves. When the coil degrades or fails — typically through heat damage, wire breakage, or insulation breakdown — the associated valve loses actuation, which can result in lost vibration output, erratic machine behavior, or a no-start condition.
