Multiquip 37661 4030 Engine Pivot Pin

The Multiquip 37661 is a genuine OEM 4030 Engine Pivot Pin designed for PS, SP, and CS series pavement saws. As a direct OEM replacement, this pin is manufactured to the same specifications as the original component, ensuring a correct fit across compatible machines. Confirmed fitment includes PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030. Keeping this pin in good working condition is essential to maintaining proper engine positioning and operational stability on the saw.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the pin seats and holds correctly within the engine pivot assembly without slop or misalignment.
• Drop-In Engine Mount Fit — Designed to install directly into the existing pivot mount points on 4030-series pavement saw engine assemblies with no reworking of surrounding hardware.
• Broad PS, SP, and CS Series Compatibility — Fits PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 pavement saws.
• Pivot Stability Under Load — A correctly fitted engine pivot pin keeps the power unit firmly located during blade engagement, preventing unwanted movement that can affect cut quality and accelerate wear on surrounding components.
• Operational Safety — A worn or missing engine pivot pin can allow the engine assembly to shift unexpectedly during operation; replacing it with a genuine OEM pin restores secure, controlled engine positioning.

The engine pivot pin is a hardened fastening component that connects the engine assembly to the saw's main frame at the pivot point, allowing controlled positioning of the power unit while keeping it securely anchored during operation. When this pin wears, bends, or goes missing, the engine can shift or rock on its mount, introducing vibration, misalignment between the engine output and drivetrain, and uneven stress on the surrounding frame. Replacing a damaged or worn pivot pin with the correct OEM part restores the rigid, stable connection the engine assembly depends on to deliver consistent cutting performance.
