Multiquip 30203 Roll Pin 3/16 x 7/8

The Multiquip 30203 is a genuine OEM Roll Pin 3/16 x 7/8 designed for Whiteman walk-behind power trowels including the JH55C, JH90C, JS60C, BH90C, BH11C, and BS90C. As a direct OEM replacement, this pin meets the original engineering specifications for these machines, ensuring a correct, trouble-free installation every time. Sourced directly through Multiquip's authorized parts network, the 30203 is the same pin that ships on new equipment — no guesswork about compatibility. Keep a spare on hand to minimize unplanned service interruptions during finishing operations.

Key Features

• Genuine OEM Construction: — Manufactured to the same material grade and dimensional tolerances as the original pin, ensuring consistent shear strength and retention force in the trowel assembly.
• Direct Drop-In Replacement: — The 3/16 x 7/8 specification matches the original bore and seating depth exactly, so the pin seats fully without rework or resizing of the host component.
• Broad Whiteman Trowel Compatibility: — Confirmed fitment across JH55C, JH90C, JS60C, BH90C, BH11C, and BS90C walk-behind power trowel models.
• Maintains Blade and Drive Engagement: — A correctly installed roll pin keeps critical rotating and pivot components locked in position, allowing the trowel blades to maintain consistent pitch and rotation under load.
• Low-Cost Insurance Against Downtime: — Roll pins are inexpensive consumables that can cause major assembly failures when they wear or shear; stocking part number 30203 means a fast fix when you need it most.

A roll pin — sometimes called a slotted spring pin — is a hollow, slotted fastener that compresses slightly as it is driven into a drilled hole, using spring tension to hold itself and the surrounding components firmly in place. In a walk-behind power trowel, roll pins are used to secure pivot points, blade spider arms, handle linkages, and other assemblies that experience continuous vibration and rotational load. When a roll pin shears or backs out, the component it was retaining can shift, loosen, or disengage entirely, which can affect blade pitch consistency or cause mechanical noise and accelerated wear on adjacent parts. Replacing a worn or failed pin promptly restores the connection and prevents secondary damage to more costly components.
