The Multiquip 584021 is a genuine OEM Saw FNR Control Detent Ball designed for SP series pavement saws and flat saws. This small but critical component is a direct OEM replacement, verified for compatibility across a wide range of SP series models including SP303516, SP303520, SP303526, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP6457, and SP4. Sourced directly from Multiquip, the part meets the exact specifications of the original part it replaces. When your forward-neutral-reverse control feels imprecise or fails to hold position, replacing the detent ball restores crisp, positive engagement to the saw's directional control system.
Key Features
- OEM-Spec Detent Function — Manufactured to the exact geometry and hardness required for positive ball-detent engagement in the FNR control mechanism.
- Drop-In Replacement — Installs directly into the existing FNR control housing with no machining or modification to the saw body.
- Broad SP Series Compatibility — Confirmed fitment across SP303516, SP303520, SP303526, SP303530, SP4, SP605716, SP605720, SP605726, SP605730, SP605736, and SP6457 pavement and flat saws.
- Restores Directional Control Precision — A worn or missing detent ball causes the FNR lever to slip out of position mid-cut; a fresh 584021 locks each direction selector position firmly in place.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component, ensuring the correct fit and function that the SP series control assembly was engineered around.
The detent ball in a saw's forward-neutral-reverse control acts as a mechanical indexing element — it seats into recessed pockets within the control housing to hold the directional selector firmly in forward, neutral, or reverse. This prevents the lever from drifting between positions during operation, which is essential for accurate, controlled cutting passes. When the detent ball wears flat or goes missing entirely, the FNR lever loses its defined positions, leading to unintended direction changes and loss of operator control over blade travel.
