Multiquip 520009 V-Belt 3VX 450 5 G Powerband

The Multiquip 520009 V-Belt 3VX 450 5 G Powerband is a genuine OEM drive belt designed for MQ Pavement Saws in the SP6457 series and Flat Saws in the SP4 series. As a direct OEM replacement, 520009 is manufactured to the same specifications as the original belt, ensuring a correct installation without guesswork. Sourced directly through the Multiquip parts network, this belt is the right call when you need to get your saw back to full cutting capacity fast.

Key Features

• OEM-Grade Powerband Construction — Banded 3VX profile delivers the same load capacity and flex rating as the original, maintaining consistent power transfer under heavy cutting demands.
• Direct Drop-In Replacement — Matches the original belt routing and sheave profile on SP6457 and SP4 series saws, so installation follows the standard service procedure without additional hardware.
• Compatible with SP6457 and SP4 Series — Confirmed fitment across MQ Pavement Saws and Flat Saws in these model families; always verify against your model code before ordering.
• Sustained Drive Power Under Load — A worn or cracked drive belt causes blade slippage, uneven cuts, and loss of RPM under load; a correctly tensioned Powerband belt keeps blade speed consistent through each pass.
• Reduced Slippage Risk — The banded multi-rib design resists rollover and lateral movement in the sheave groove, which is especially important on saw applications where vibration is constant.

The drive belt on a pavement or flat saw transmits engine power to the blade arbor, maintaining the blade RPM needed for clean, controlled cuts through asphalt or concrete. A Powerband-style belt links multiple V-belt ribs into a single banded unit, which prevents individual ribs from flipping or twisting under the lateral forces common in saw drive systems. When this belt stretches, cracks, or separates, blade speed drops, cut quality suffers, and continued operation risks damage to the drive sheaves and arbor bearings.
