The Wacker Neuson Thrust Washer is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100 C tandem roller series. Sourced directly from Wacker Neuson, this thrust washer meets the exact material and dimensional standards of the original part installed at the factory. It is a verified fit across the full RD18 family, including US and SE variants, giving you confidence that the part will seat and perform correctly on your machine. When your roller is down, getting the right part the first time is what matters most — the delivers exactly that.
Key Features
- Genuine OEM Material Integrity — Manufactured to Wacker Neuson's specified hardness and surface finish tolerances, ensuring the washer handles axial load transfer without premature wear or deformation.
- Drop-In Replacement — Matches the original profile and bore dimensions exactly, so the 5100029590 installs directly into the drivetrain stack without rework or shimming.
- Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100 C models across standard, US, SE, and .3-series variants, covering a wide range of production years and configurations.
- Sustained Drivetrain Performance — A correctly functioning thrust washer keeps axial forces controlled within the drive assembly; a worn or missing washer accelerates bearing and shaft damage, leading to costly secondary repairs.
- Verified Part Number — Wacker Neuson OEM part number 5100029590 is confirmed against multiple RD18 assembly configurations, reducing the risk of ordering errors.
A thrust washer sits between rotating and stationary components in a drive assembly, absorbing axial (end-to-end) thrust loads that would otherwise be transferred directly onto adjacent bearings or housings. In a tandem roller like the RD18 series, the drivetrain is subject to continuous vibration and directional load changes, making the thrust washer a critical wear item that protects more expensive surrounding components. When a thrust washer wears thin or fails, you will typically notice increased end-play, abnormal noise from the drive assembly, and accelerated wear on the bearing surfaces it was protecting.
