The Wacker Neuson Solenoid Coil is a genuine OEM solenoid coil designed for the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series tandem rollers, including standard, C, O, and DPF variants. Sourced directly from Wacker Neuson, this is the same part installed at the factory, ensuring correct electrical resistance, coil winding specification, and connector fit for your machine. Broad compatibility across the RD tandem roller lineup makes the a reliable stock item for fleet operators and service teams running multiple machine variants.
Key Features
- Correct Coil Specification: — Wound to OEM resistance and inductance ratings, ensuring the solenoid actuates with the precise magnetic force the hydraulic or fuel circuit demands.
- Direct OEM Connector Match: — Plug-and-play electrical connection fits the factory harness on RD-series tandem rollers without splicing or adapter wiring.
- Wide RD-Series Coverage: — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, C, O, and DPF configurations, including .3-generation models.
- Protects Hydraulic or Fuel Circuit Control: — A properly functioning solenoid coil ensures clean on/off switching of the controlled valve; a failed coil causes loss of function, erratic behavior, or a machine that won't start or move.
- Electrical Safety Compliance: — As a genuine OEM electrical component, the 5100012112 meets the insulation class and voltage ratings specified for these machines, reducing the risk of short circuits or coil burnout from mismatched aftermarket substitutes.
A solenoid coil is an electromagnetic winding that, when energized, generates a magnetic field to open or close a valve — typically in the hydraulic or fuel system of a compaction machine. On Wacker Neuson RD-series tandem rollers, the solenoid coil controls critical on/off functions that govern machine operation and drive response. When the coil degrades or burns out, the valve it controls stops responding correctly, which can result in lost drive, engine shutdown issues, or an inability to engage compaction functions — making prompt replacement essential to keeping the roller productive on site.
