The Multiquip EM491722 Pin Spiral V30-4 is a genuine OEM component designed for V30 and V305 series walk-behind vibratory rollers, including the V304EH, V304ER, V304EY, V303E, V305EH, and V305EK. As a direct OEM replacement, this pin is manufactured to Multiquip's original design specifications, ensuring a correct installation with no guesswork on fit or function. DHS Equipment sources this part directly through authorized Multiquip supply channels, so you can order with confidence knowing you are receiving the exact component your machine requires.
Key Features
- Genuine OEM Construction: — Manufactured to the original design spec for the V30-4 application, delivering the same dimensional accuracy and material grade as the part that left the factory floor.
- Direct Drop-In Installation: — Engineered to match the original mounting interface on V30 and V305 series rollers, so installation aligns without modification or shimming.
- Broad V-Series Compatibility: — Confirmed fitment across V304EH, V304ER, V304EY, V303E, V305EH, and V305EK walk-behind vibratory roller models.
- Maintains Drivetrain Integrity: — A correctly fitted spiral pin locks rotating or sliding components in proper alignment; a worn or missing pin allows unwanted movement that accelerates wear on surrounding parts.
- Verified Part Number: — Listed under Multiquip part number EM491722, cross-referencing directly to the V30-4 application for accurate ordering.
A spiral pin — sometimes called a roll pin or coiled spring pin — is a fastening component used to secure shafts, gears, levers, or linkage assemblies in place within a machine. The coiled, slotted design allows the pin to compress slightly on installation, creating a tight interference fit that resists vibration-induced loosening over time. On walk-behind vibratory rollers like the V30 series, these pins are found in drivetrain and control linkage locations where precise rotational or positional locking is essential. When a spiral pin shears or backs out, the connected components lose their fixed relationship, leading to erratic operation, audible rattling, or complete loss of function in the affected assembly.
