The Multiquip 508386 is a genuine OEM Washer 3/16 designed for AR13D, AR13H, AR13HA/HAR, and AR13HC asphalt ride-on rollers. As a direct Multiquip OEM part, 508386 is manufactured to the same standards as the original hardware installed at the factory, ensuring a correct, trouble-free fit on your machine. This washer is sourced directly through authorized Multiquip distribution channels and is verified compatible with the AR13 roller series.
Key Features
- Genuine OEM Hardware Grade — Manufactured to exact Multiquip tolerances, ensuring consistent load distribution and surface protection specific to roller assembly applications.
- Direct Drop-In Fit — Sized and profiled to seat correctly against mating fasteners and surfaces on AR13 series roller assemblies without rework or shimming.
- Broad AR13 Series Coverage — Confirmed fitment across AR13D, AR13H, AR13HA/HAR, and AR13HC asphalt ride-on roller models.
- Preserves Clamping Integrity — A correctly sized washer maintains proper fastener torque retention; a worn or incorrect washer can allow fasteners to loosen under the vibration loads typical of roller operation.
- Verified OEM Part Number — Part number 508386 is the exact Multiquip catalog reference, eliminating guesswork when ordering service hardware for your roller.
A washer serves as a load-distributing interface between a fastener and the surface it clamps against. By spreading the clamping force over a wider area, it protects the mating surface from damage and helps the fastener maintain its holding strength over time. On ride-on rollers like the AR13 series — which operate under constant vibration and heavy compaction loads — correctly spec'd hardware is essential; an undersized or worn washer can allow fasteners to work loose, leading to misalignment or component movement that accelerates wear elsewhere in the assembly.
