The Multiquip 509144 is a genuine OEM Bolt 3/16" x 1-3/4" designed for the AR13H, AR13HC, AR13HA/HAR, and AR13D ride-on asphalt roller series. Sourced directly from Multiquip, this fastener meets the exact material grade and dimensional specifications called out in the original equipment design. Verified fitment covers the full AR13 roller lineup, so you can order with confidence knowing 509144 is the correct part for your machine.
Key Features
- Correct Grade and Dimensional Spec — Manufactured to the precise diameter, thread pitch, and length required for the AR13 roller assembly, ensuring proper clamp load and joint integrity.
- Genuine OEM Sourcing — Produced to Multiquip's original design, not a generic hardware substitute, so the fastener performs exactly as engineered for this application.
- Direct Drop-In Replacement — Matches the original mounting points and thread engagement on AR13 series machines, allowing a straightforward like-for-like swap during service.
- Broad AR13 Series Coverage — Confirmed fitment across AR13H, AR13HC, AR13HA/HAR, and AR13D ride-on asphalt rollers in both Honda and diesel configurations.
- Structural Fastener Integrity — Using the correct OEM bolt preserves the designed clamping force on critical roller components, preventing loosening, vibration damage, or premature wear at the joint.
A bolt of this specification serves as a structural fastener within the AR13 ride-on asphalt roller assembly, holding key components securely together under the constant vibration and load cycles that compaction work demands. When a fastener is the wrong size, grade, or thread pitch, it can work loose during operation or fail to deliver adequate clamping force, leading to component movement, accelerated wear, and potential damage to surrounding parts. Replacing a worn or missing fastener with the correct OEM part restores the joint to its designed specification and keeps the roller operating as intended.
