The Multiquip 506044 Cotter Key is a genuine OEM replacement designed for AR13D series ride-on asphalt rollers. Sourced directly through Multiquip's authorized parts program, this cotter key is built to the same specification as the original hardware installed at the factory. Confirm your model code against the AR13D fitment reference before ordering to ensure an exact match.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same material and dimensional spec as the original, ensuring proper retention force and resistance to shear under load.
- Drop-In Installation — Matches the original pin diameter and leg spread of the AR13D application, so it seats and locks without rework or modification to surrounding components.
- AR13D Series Fitment — Confirmed for Multiquip AR13D ride-on asphalt rollers; verify your model code before purchase.
- Retains Critical Fastener Assemblies — A cotter key in service keeps pins, clevis bolts, and linkage hardware locked in position. A failed or missing cotter key can allow components to back out during operation, leading to unplanned disassembly of load-bearing joints.
- Safety-Relevant Fastener — On roller equipment, cotter keys often secure steering linkage, drum drive, and axle pin assemblies. Using the correct OEM part maintains the mechanical integrity of these systems.
A cotter key is a split-pin fastener inserted through a hole in a bolt, shaft, or clevis pin, then bent open to lock the assembly in place. On a ride-on roller like the AR13D, cotter keys are used at pivot points, linkage joints, and drum pin connections to prevent hardware from walking out under vibration and repeated loading cycles. When a cotter key is missing, sheared, or not properly spread, the pin it retains can migrate out of position — potentially causing loss of control of a steered or driven component. Replacing worn or damaged cotter keys as part of routine inspection keeps these connections secure and the machine operating as intended.
