The Wacker Neuson is a genuine OEM Crankshaft Thrust Washer designed for a range of Wacker Neuson ride-on trowels, tandem rollers, floor saws, and portable generators. As a direct OEM replacement, part is manufactured to the exact tolerances required to control crankshaft end-play and maintain proper axial alignment within the engine. Confirmed fitment includes the CRT36-24A series ride-on trowels, RD12A-90 tandem rollers, BFS 2020AS floor saw, RD11A and RD11AEC hydrostatic double drum vibratory rollers, and GS12Ai portable generator. Sourcing the correct OEM part ensures your engine assembly goes back together right the first time.
Key Features
- OEM-Spec Thrust Surface Tolerance — Manufactured to the exact thickness and hardness spec required to control crankshaft end-play, preventing premature axial wear in the engine assembly.
- Drop-In Engine Replacement — Seats directly into the crankshaft journal position without reworking the housing or adjacent bearing surfaces.
- Broad Wacker Neuson Fitment — Compatible with CRT36-24A ride-on trowels, RD12A-90 tandem rollers, BFS 2020AS floor saw, RD11A/RD11AEC rollers, and GS12Ai generator.
- Protects Engine Longevity — A correctly functioning thrust washer keeps crankshaft movement within spec; a worn or missing washer allows axial migration that accelerates damage to bearings and seals throughout the engine.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, ensuring the material grade and dimensional profile match the original component exactly.
A crankshaft thrust washer controls the side-to-side (axial) movement of the crankshaft within the engine block. It acts as a thin but critical buffer between the crankshaft and the bearing housing, absorbing the thrust loads generated during normal engine operation and keeping the crankshaft centered within its designed range of motion. When a thrust washer wears down or fails, the crankshaft develops excessive end-play, which can cause knocking, accelerated bearing wear, oil seal failure, and — if left unaddressed — serious internal engine damage across any of the machines this part serves.
