The Multiquip 521004 V-Belt AX-38 is a genuine OEM drive belt designed for Multiquip SP-series pavement saws, including the SP605720, SP605726, SP605716, SP605730, and SP605736. As a factory-sourced component, this belt matches the original specification exactly, ensuring correct tension, pulley engagement, and power transfer right out of the box. DHS Equipment supplies this part direct, so you can be confident you are getting the right belt for your machine.
Key Features
- Genuine OEM Belt Construction — Manufactured to the same rubber compound and cord reinforcement spec as the original, maintaining consistent grip and flex performance across the drive system.
- AX-38 Cogged Profile — The cogged AX cross-section reduces heat buildup and flexing resistance compared to a standard wrapped belt, extending service life in demanding cut cycles.
- Direct Drop-In Replacement — Correct length, width, and cogging profile for SP605720, SP605726, SP605716, SP605730, and SP605736 pavement saws — routes and seats to the existing pulleys without adjustment.
- Sustained Blade Drive Power — A correctly tensioned belt keeps full power flowing from the engine to the blade shaft; a worn or slipping belt causes blade speed drop, uneven cuts, and accelerated pulley wear.
- Verified by Part Number 521004 — Cross-reference 521004 against your machine's parts manual before ordering to confirm application for your specific SP-series model.
The V-Belt AX-38 is the primary drive link between the engine output pulley and the blade drive system on SP-series pavement saws. It transmits rotational power continuously during cutting, so its condition directly affects blade speed consistency and overall cut quality. When the belt stretches, cracks, or glazes, power transfer becomes erratic — resulting in stalled cuts, excessive pulley heat, and the risk of unexpected belt failure mid-job. Replacing a worn belt with the correct Multiquip 521004 restores full drive efficiency and protects the pulleys from the extra stress a slipping belt creates.
