The Multiquip 521007 V-Belt AX-42 is a genuine OEM V-Belt designed for the SP605716, SP605726, SP605720, SP605730, and SP605736 Street Pro Series pavement saws. As a factory-sourced component, the 521007 meets the exact dimensional and tensile specifications required to deliver consistent blade drive performance on these machines. Sourced directly through Multiquip's OEM parts program, this belt is a direct replacement for the original unit installed at the factory. DHS Equipment stocks this part to keep your pavement saw cutting on schedule.
Key Features
- OEM-Matched Belt Profile: — AX-42 cogged construction matches the original drive system geometry, ensuring correct wrap angle and engagement on the drive pulleys of SP-series pavement saws.
- Drop-In Replacement: — Built to the same AX-42 cross-section and length as the factory-installed belt, allowing straightforward installation without shimming or pulley adjustment.
- Wide SP-Series Compatibility: — Confirmed fit across five Street Pro pavement saw models: SP605716, SP605726, SP605720, SP605730, and SP605736.
- Sustained Blade Drive Output: — A correctly tensioned AX-42 belt transfers engine power to the blade arbor without slip or vibration; a worn or cracked belt causes blade speed drop, uneven cuts, and potential belt failure mid-cut.
- Genuine Multiquip OEM Part: — Manufactured to Multiquip's specifications under part number 521007, giving you the same component used in original production builds.
The V-belt is the primary power transmission link between the engine and the cutting blade arbor on a pavement saw. It transfers rotational force from the engine pulley to the blade drive pulley, maintaining the blade speed needed to cut asphalt or concrete cleanly and at depth. When a V-belt stretches, cracks, or frays, drive efficiency drops — the blade loses speed under load, cuts become ragged, and in severe cases the belt can break entirely and halt the machine. Replacing a worn belt promptly with the correct AX-42 profile restores full power transfer and protects the pulleys from the accelerated wear caused by a slipping or mismatched belt.
