The Multiquip 37577 Belt 6G 3 VX 500 Optibelt is a genuine OEM drive belt designed for the PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 series pavement saws. As a factory-sourced component, this belt meets the original engineering specifications for power transmission on these machines. Sourced directly from Multiquip, the part ensures a correct drop-in fit for PS, SP, and CS403000-series saws without the guesswork of cross-referencing aftermarket alternatives. Keep a spare on hand to get your saw back up and cutting with minimal interruption.
Key Features
- Genuine OEM Optibelt Construction — Manufactured to the same tension and flex specifications as the original belt, maintaining consistent power transfer from engine to blade arbor across the full operating RPM range.
- Direct-Fit for PS, SP, and CS403000-Series Saws — Engineered to seat correctly on the OEM pulleys of PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 models without pulley adjustment or shimming.
- Sustained Blade Power Under Load — A worn or slipping drive belt causes blade speed drop and uneven cuts; a correctly tensioned OEM belt maintains full torque delivery to the cutting blade through hard pavement passes.
- Broad Saw Family Coverage — A single part number covers the full range of Multiquip PS, SP, and CS403000-series pavement saws, simplifying inventory for multi-saw operations and rental fleets.
- Verified Multiquip Part Number — Ordering by OEM part number 37577 confirms you receive the exact belt specification called out in the Multiquip parts manual for these machines.
A drive belt on a pavement saw transmits engine power to the blade arbor, spinning the diamond or abrasive cutting blade at the speed needed to cut through asphalt and concrete. When the belt stretches, cracks, or loses grip on the pulleys, blade RPM drops, cutting performance suffers, and the belt can fail mid-cut — leaving the saw down on the job. Replacing the belt on schedule with a correct-spec Optibelt unit restores full power transfer and keeps blade speed consistent from the start of a cut to the finish.
