The Multiquip 1757 Roll Pin 3/16" x 1-3/8" is a genuine OEM component designed for B Series and J Series international walk-behind power trowels and MQD2HA and MQD3HA diaphragm pumps. As a direct OEM replacement sourced through Multiquip's authorized parts network, the 1757 delivers the exact dimensional tolerances required for a secure, rattle-free installation. Verify your model against the fitment list below before ordering to ensure a correct match.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact 3/16" diameter and 1-3/8" length specifications, ensuring the pin seats flush and holds firm under dynamic load and vibration.
- Direct Drop-In Installation — Engineered to the same cross-slot rolled steel profile as the original, so it presses into the bore without machining or modification to the surrounding assembly.
- Broad Cross-Family Fitment — Confirmed for B Series and J Series international walk-behind trowels and MQD2HA and MQD3HA diaphragm pumps, covering both concrete finishing and fluid-handling applications.
- Secure Retention Under Vibration — The slotted roll design allows radial flex on installation while maintaining clamping force in service, resisting loosening even under sustained equipment vibration.
- OEM Supply Chain Confidence — Sourced directly through Multiquip's authorized parts program, so you receive the same component installed at the factory — not a dimensional approximation.
A roll pin is a hollow, slotted fastener pressed into aligned holes across two or more mating components to lock them in position and prevent relative rotation or axial movement. Because the pin is slightly oversized for the bore, it compresses on installation and exerts outward spring pressure against the hole wall, holding the assembly together without threads or adhesive. In walk-behind trowels, roll pins are commonly used to secure blade arms, handles, and drive components. In diaphragm pumps, they retain valve seats, cam followers, and linkage pins. A worn, sheared, or missing roll pin allows the connected parts to shift or spin freely, which can cause rapid wear on surrounding components, loss of mechanical drive, or pump failure.
