The Wacker Neuson Thrust Washer is a genuine OEM component designed for the GP-series portable generators, including the G40, G50, G60, G70, G95, and G110 families. Sourced directly from Wacker Neuson, this thrust washer meets the exact tolerancing and material specifications required for proper drivetrain alignment and axial load management within these generator units. It is a direct-fit replacement for both standard and premium configurations across the G-series lineup, covering North American, Brazilian, and LATAM market variants. Whether you are servicing a G95 50Hz premium unit or a G110 Brazil value model, part number is the correct OEM-specified component for the application.
Key Features
- Genuine OEM Tolerancing — Manufactured to the exact axial load ratings and material hardness specifications Wacker Neuson requires for the G-series generator drivetrain, ensuring correct thrust control under sustained load.
- Drop-In Drivetrain Replacement — Seats directly into the existing thrust position without modification, maintaining proper shaft end-play and bearing preload alignment.
- Broad G-Series Compatibility — Confirmed fitment across G40, G50, G60, G70, G95, and G110 generator models, including standard, premium, 50Hz LATAM, and Brazil-market variants.
- Protects Adjacent Bearing Surfaces — A correctly functioning thrust washer prevents metal-to-metal contact at the shaft shoulder, preserving the surrounding bearing and housing components from premature wear.
- Covers Multiple Market Configurations — A single part number spans a wide range of G-series build specs, simplifying procurement for fleets running mixed generator configurations.
A thrust washer is a flat bearing element positioned against a rotating shaft to absorb axial (end-thrust) loads and prevent lateral movement within the assembly. In a portable generator, it keeps the rotor or crankshaft centered and limits the wear transferred to adjacent bearings and housings. When a thrust washer wears thin or fails, shaft end-play increases, causing vibration, accelerated bearing damage, and potential misalignment between the engine and generator head — problems that can quickly escalate into costly internal repairs if left unaddressed.
