The Wacker Neuson Pulley is a genuine OEM Pulley designed for the G50, G70, G100, and G120 series mobile and skid-mounted generators. As a direct OEM replacement, this pulley is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, reliable installation every time. Compatibility spans multiple generator configurations across the G-series lineup, including Tier 3 and Tier 4i variants and switchable 600-volt models. When you need a dependable replacement for this drivetrain component, part number is the factory-correct answer.
Key Features
- OEM Belt Path Geometry — Manufactured to the exact groove profile and bore dimensions Wacker Neuson specifies, so belt tracking and tension remain correct from the first start.
- Drop-In Fitment Across G-Series Generators — Mounts to the same shaft and hardware as the original, covering G50, G70, G100, and G120 skid and mobile generator models without modification.
- Broad Model Coverage — Compatible with Tier 3, Tier 4i, and switchable 600-volt G-series configurations, making 5100034590 a single part that covers a wide fleet range.
- Sustained Generator Output — A correctly sized pulley maintains the engine-to-alternator speed ratio that keeps the generator producing steady power output; a worn or undersized pulley leads to belt slip and inconsistent voltage.
- Genuine Wacker Neuson Quality — Sourced directly through the OEM supply chain, this pulley meets the material hardness and balance tolerances required for continuous-duty generator operation.
A pulley transfers rotational force from the engine to driven accessories — in a generator set, this typically means driving the alternator or ancillary components via a belt. The pulley's diameter and groove profile control the speed ratio between the engine and the driven component, which directly affects the alternator's rotational speed and, in turn, the quality and stability of electrical output. When a pulley wears, cracks, or becomes misaligned, belt slip or belt failure follows, causing the generator to lose output or shut down entirely under load.
