The Wacker Neuson Solenoid Complete is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem ride-on rollers. As a factory-sourced part, it matches the exact electrical and mechanical specifications of the original unit fitted at the time of manufacture, ensuring a direct swap without guesswork. This solenoid complete covers an extensive range of RD27 variants — including Pro, Basic, and T4F configurations — making it a single reliable solution for fleets running multiple RD27 builds. Keep part number on hand to minimize unplanned downtime across your roller lineup.
Key Features
- Correct Electrical Output for Hydrostatic Control — Matched to the original coil resistance and actuation voltage, ensuring the solenoid engages and releases the hydrostatic circuit with the same precision as the factory unit.
- Direct-Swap Installation — Supplied as a complete solenoid assembly, so it connects to existing wiring harness and mounting points on the RD27 without additional hardware or adaptation.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 variants across Hydrostatic Vibratory Roller, Ride-On Roller, RD27 Pro Tandem Roller, and T4F (Pro and Basic) configurations.
- Genuine OEM Dependability — Sourced directly from Wacker Neuson, this part meets the same build tolerances and material standards as the component originally installed on your machine.
- Protects Drivetrain Integrity — A correctly functioning solenoid maintains proper hydraulic directional control on the roller; a failed unit can cause erratic propulsion, loss of drive, or unintended movement on grade.
- Electrical Safety Assurance — As a genuine OEM electrical assembly, the 5200017641 is built to the correct insulation and rated load specifications, reducing the risk of wiring faults or solenoid failure under operating load.
A solenoid in a hydrostatic roller acts as an electrically operated switch within the hydraulic control circuit, converting an electrical signal from the operator controls into a mechanical action that directs hydraulic fluid flow — governing forward, reverse, and braking functions. When the solenoid functions correctly, the machine responds predictably and smoothly to operator inputs. A worn or failed solenoid can cause sluggish response, loss of drive in one direction, or the machine becoming unresponsive to control inputs entirely, creating both operational and safety concerns on compaction sites.
