The Multiquip 511778 AR-13H Adapter is a genuine OEM component designed for the AR13H, AR13HC, AR13HA/HAR, and AR13D asphalt ride-on rollers. Sourced directly from Multiquip, this adapter is manufactured to the same specifications as the original part installed at the factory, ensuring a correct, reliable installation every time. Verified compatibility across the AR13 roller series makes 511778 the right call when you need to restore your machine to full working order without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the adapter seats, threads, and connects exactly as the original did on the production line.
- Direct-Fit Replacement — Engineered to drop into the AR13 roller drivetrain or hydraulic circuit without rework, shimming, or machining to the mating interface.
- Broad AR13 Series Coverage — Confirmed fitment for AR13H, AR13HC, AR13HA/HAR, and AR13D ride-on asphalt rollers, covering both Honda and diesel-powered variants in the lineup.
- Sustained Drive or Fluid Transfer Integrity — A correctly fitted adapter maintains proper alignment and sealing within the roller's system, preventing power loss, fluid weep, or premature wear on adjacent components caused by a worn or damaged original.
- OEM Part Number Traceability — Ordering by Multiquip part number 511778 ensures you receive the exact superseded or current revision of this adapter, not a generically substituted piece.
An adapter in a ride-on roller serves as a precision interface component, connecting two mating assemblies — such as a drive shaft, drum, or hydraulic fitting — so that torque, motion, or fluid can transfer correctly between them. When an adapter wears, cracks, or becomes damaged, the connection it bridges loses integrity, which can result in misalignment, vibration, fluid leaks, or a complete loss of drive to the compaction drum. Replacing a failed adapter promptly with the correct OEM part restores the mechanical or hydraulic circuit to its intended operating condition and protects the surrounding components from secondary damage.
