The Multiquip 90401ZG3000 Washer 20mm is a genuine OEM component designed for AR13HA/HAR, AR13HC, and AR13H asphalt ride-on rollers, as well as the GA9.7HE gasoline powered generator. As an authentic Multiquip OEM part, the 90401ZG3000 is manufactured to the exact material and dimensional standards of the original, ensuring a correct fit without guesswork. Sourced directly through authorized Multiquip distribution channels, this washer is the specification-correct choice for technicians and operators maintaining their equipment to original build standards. Confirm your model code against the fitment list before ordering to ensure compatibility.

Key Features

• OEM-Grade Material Specification — Manufactured to the original dimensional and hardness standards for a 20mm washer, ensuring proper load distribution and clamping integrity at the fastener joint.
• Drop-In Installation — Matches the original hardware configuration exactly, seating correctly against mating surfaces without shimming or modification to fastener stacks.
• Confirmed Fitment — Compatible with AR13HA/HAR, AR13HC, and AR13H asphalt ride-on rollers, and the GA9.7HE gasoline powered generator.
• Protects Fastened Joints — A correctly sized washer distributes clamping load evenly across the bearing surface; an undersized, worn, or missing washer can lead to fastener loosening, surface damage, and premature joint failure under vibration.
• Genuine Multiquip OEM Part — Supplied under the original Multiquip part number 90401ZG3000, so you can cross-reference against your machine's parts manual with confidence.

A washer functions as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it secures. By spreading clamping force over a wider area, it prevents the fastener head from pulling through or damaging softer materials and helps maintain consistent torque retention, which is especially important on equipment subject to continuous vibration like compaction rollers and power generators. When a washer is missing, deformed, or incorrectly sized, fastener joints can loosen progressively under operating loads, leading to component movement, accelerated wear on mating parts, and potential mechanical failure if left unaddressed.
