The Wacker Neuson Spring is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including PTS4V centrifugal trash pumps, GPS9700 and GPS8500 portable generators, GS8.5V and GS9.7V portable generators, and the RD11V hydrostatic double drum vibratory roller. As a direct OEM replacement, the is sourced and specified by Wacker Neuson to meet the same standards as the original part installed at the factory. This spring services multiple machine families, making it a useful part to keep on hand for mixed fleets running PTS4V, GPS9700, and RD11V equipment. Confirm your machine's model number and machine number before ordering to ensure correct application.
Key Features
- Genuine OEM Tension and Rate Specification — Manufactured to the exact load and travel spec required by each compatible machine, ensuring the spring performs its intended mechanical function without substitution guesswork.
- Drop-In Replacement — Engineered to the same dimensions and end configuration as the original, allowing installation into the existing mount or seat without reworking surrounding components.
- Broad Cross-Family Fitment — A single part number covering PTS4V centrifugal trash pumps, GPS8500 and GPS9700 portable generators, GS8.5V and GS9.7V generators, and the RD11V hydrostatic double drum vibratory roller.
- Consistent Mechanical Return Force — A correctly rated spring maintains positive return or tension on the mechanism it controls; a fatigued or broken spring can cause erratic operation, control lag, or failure to return to a neutral or safe position.
- Genuine Wacker Neuson Parts Lineage — Supplied under the original Wacker Neuson part number 5000118491, backed by the manufacturer's parts program for traceability and quality assurance.
A spring in this context serves as a mechanical return or tensioning element within the machine's control, throttle, valve, or linkage assembly. It stores energy when compressed or extended and releases it to return a component to its resting position, maintain consistent pressure, or hold a mechanism in place against vibration. When a spring fatigues, takes a set, or breaks, the mechanism it controls may stick, fail to reset, or operate inconsistently — leading to reduced control response or the inability to start or run the machine correctly. Replacing a worn spring promptly restores predictable mechanical behavior across the affected system.
