Key Features
- Genuine OEM Construction — Manufactured by Multiquip to exact dimensional and material standards for coupling components, ensuring correct torque transfer and long service life under continuous roller operation.
- Direct-Fit Replacement — Engineered to match the original mounting interface on AR-series rollers, so installation follows the same procedure as the factory-fitted part.
- Broad AR-Series Compatibility — Confirmed fitment for AR13HC, AR13HA, AR13HA/HAR, AR13H, AR13D, and AR14H asphalt ride-on rollers under a single part number.
- Maintains Drive System Integrity — A properly functioning coupler transmits power smoothly between drivetrain components; a worn or failed coupler introduces vibration, slippage, and accelerated wear on adjacent parts.
- Verified Part Number — Order with confidence knowing 508665 is the exact Multiquip part number cross-referenced to these roller models.
A coupler serves as the mechanical link between two rotating drivetrain components, transmitting torque while accommodating minor shaft misalignment and absorbing operational shock loads. On asphalt ride-on rollers like the AR13 and AR14 series, the coupler plays a critical role in maintaining smooth, consistent drum rotation across varied compaction surfaces. When a coupler wears, cracks, or fails, the result is uneven power delivery, increased vibration, and potential damage to connected shafts and bearings — making timely replacement essential to protecting the broader drivetrain.
