The Multiquip 521005 V-Belt AX-31 is a genuine OEM V-Belt designed for the SP303520, SP303526, SP303530, and SP303516 Street Pro Series pavement saws. Sourced directly from Multiquip, this belt matches the original specification to ensure correct tension, tracking, and power transfer on your saw. It is the exact replacement belt used in production, so installation drops straight into the existing drive system without guesswork.
Key Features
- Genuine OEM Belt Construction — Manufactured to the same compound and dimensional spec as the belt installed at the factory, ensuring consistent stretch resistance and flex fatigue life under heavy cutting loads.
- AX-31 Profile for Direct Drive Compatibility — The cogged AX cross-section fits the existing pulleys and sheaves on SP-series pavement saws, seating correctly without adjustment to belt guards or tensioners.
- Confirmed Fitment for SP303520, SP303526, SP303530, and SP303516 — Verified against Multiquip's Street Pro Series pavement saw lineup, covering the SP303516 through SP303530 range.
- Consistent Blade Speed Under Load — A correctly tensioned OEM belt maintains steady RPM transfer from the engine to the blade spindle, supporting clean, controlled cuts through asphalt and concrete.
- Fuel and Heat Resistance — OEM belt materials resist degradation from oil mist, ambient heat, and the vibration cycles common in pavement cutting environments, extending service intervals between belt changes.
The V-belt on a pavement saw transmits rotational power from the engine to the blade drive system. When the belt is worn, cracked, or stretched beyond its operating range, blade speed becomes inconsistent and cutting performance drops — in severe cases the belt slips or breaks entirely, halting the cut mid-pass. Replacing a worn belt with the correct OEM profile restores proper tension and ensures the saw delivers the blade speed it was designed to produce.
