The Wacker Neuson is a genuine OEM Hydraulic Motor Seal Replacement Kit designed for the RT56, RT82, RT820, and RTx-SC2 series remote-controlled vibratory trench rollers. As a factory-sourced kit, it includes the correct seals to restore the hydraulic drive motor to proper operating condition without guesswork on material grade or dimensional fit. This kit covers an extensive range of RT-series configurations, including RT56-SC, RT56-SC2, RT82-SC, RT82-SC2, RT820, RT820HT, and RTx-SC2 machines. Keeping the hydraulic motor properly sealed is essential for maintaining drive performance and preventing fluid loss on demanding trench and cohesive soil compaction applications.
Key Features
- Genuine OEM Seal Material: — Factory-spec seal compounds deliver the correct compression rating and fluid compatibility for Wacker Neuson hydraulic motor circuits.
- Complete Replacement Kit: — All necessary seals are included in a single kit, allowing a full hydraulic motor reseal in one service event.
- Broad RT-Series Fitment: — Confirmed fit across RT56-SC, RT56-SC2, RT82-SC, RT82-SC2, RT820, RT820HT, and RTx-SC2 vibratory trench roller configurations.
- Restores Hydraulic Drive Integrity: — Worn or damaged motor seals cause hydraulic fluid leakage and loss of drive pressure, leading to reduced drum vibration and compaction force; this kit brings the motor back to full operating spec.
- Hydraulic System Safety: — A properly sealed hydraulic motor prevents uncontrolled fluid loss that can create slip hazards and lead to sudden loss of drive control on remote-operated equipment.
The hydraulic drive motor on a vibratory trench roller powers the rotation of the compaction drums, delivering the propulsion and vibration force needed to compact cohesive soils and trench backfill. Internal seals within the motor contain pressurized hydraulic fluid and maintain the pressure differential that generates drive torque. When these seals deteriorate through heat cycling, contamination, or normal wear, fluid bypasses the sealing surfaces, causing external leaks, reduced drive pressure, and a measurable drop in compaction output. Replacing the seals with the Wacker Neuson 5000076630 Hydraulic Motor Seal Replacement Kit restores the motor to a leak-free, full-pressure condition and prevents the broader hydraulic system damage that can follow from sustained seal failure.
