The Wacker Neuson is a genuine OEM Starter Pulley designed for PTS4V centrifugal trash pumps and GPS8500, GPS9700, GS8.5V, and GS9.7V portable generators. As a factory-sourced component, the is manufactured to the exact geometry and material spec of the original part, ensuring the recoil starter system engages and returns correctly every time. This pulley is a direct drop-in replacement with no modification to surrounding hardware. Confirm your model number before ordering — this part spans two distinct equipment families, so matching the correct fitment is essential.
Key Features
- Factory-Matched Rope Groove Geometry — Engineered to the same groove profile and diameter as the original, so the starter rope seats, wraps, and releases without slipping or binding.
- Genuine OEM Sourcing — Sourced directly from Wacker Neuson, this pulley carries the same part number and tolerances as the component installed at the factory — no guesswork on fit or function.
- Broad Cross-Family Fitment — Confirmed for PTS4V 100mm/4-inch centrifugal trash pumps and GPS8500, GPS9700, GS8.5V, and GS9.7V portable generators, covering both engine-driven equipment families in a single part number.
- Smooth, Consistent Engine Starting — A worn or cracked starter pulley causes the rope to jam, fray, or snap mid-pull. Replacing with 5000116510 restores clean, repeatable engagement on every pull stroke.
- Recoil System Integrity — The pulley works in tandem with the recoil spring and rope to return the handle automatically after each pull; a correctly functioning pulley prevents premature rope and spring wear.
The starter pulley is the spool at the heart of the recoil starter assembly. When the operator pulls the starter grip, the rope unwinds from the pulley, spinning the engine's crankshaft to initiate combustion; when released, the recoil spring rotates the pulley in reverse to rewind the rope. If the pulley cracks, warps, or wears at the groove, the rope can slip out of track, fray against edges, or fail to retract — leaving the equipment unable to start. Replacing the pulley with a properly matched component like the Wacker Neuson 5000116510 restores full starter function and protects the rope and spring from accelerated wear.
