The Wacker Neuson Travel Plunger is a genuine OEM component designed for the RD7, RD7H, RD7He, and RD7Ye series tandem rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the original, ensuring a correct, hassle-free installation. Part number covers an extensive range of RD7 configurations, including walk-behind and double drum variants, making it a go-to replacement for fleet operators and service technicians alike. When it's time to restore your roller's travel control system to full working order, this is the verified OEM part to reach for.
Key Features
- Genuine OEM Pressure Integrity — Manufactured to Wacker Neuson's original hydraulic tolerances, ensuring the plunger seats and seals correctly within the travel circuit without fluid bypass or pressure loss.
- Direct Drop-In Replacement — Engineered to the same dimensions and material grade as the original, so it installs into the existing travel control bore without modification or shimming.
- Broad RD7 Series Coverage — A single part number that fits RD7, RD7H, RD7He, and RD7Ye tandem rollers across multiple serial number ranges, including walk-behind and North America-specific configurations.
- Restored Travel Response — A worn or stuck travel plunger causes sluggish or inconsistent forward/reverse response; replacing it with part 5100029378 restores crisp, predictable machine travel.
- Verified Wacker Neuson OEM Part — Supplied as a genuine Wacker Neuson part, confirming correct part number cross-reference and eliminating the guesswork of fitment verification.
The travel plunger is a hydraulic control component that regulates the flow of fluid within the roller's travel drive circuit. It acts as a precision metering element — when the operator commands forward or reverse movement, the plunger modulates hydraulic pressure to engage the drive system smoothly and proportionally. Over time, wear or contamination can cause the plunger to stick, leak internally, or fail to return to neutral, resulting in unresponsive travel, drift, or a complete loss of drive — all of which bring compaction work to a stop and create potential safety concerns on grade.
