The Multiquip 37570 Pulley 3.7 6 3V 4.5 1A is a genuine OEM pulley designed for Multiquip and Stow pavement saws across the PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 series. As a direct factory replacement, it maintains the correct belt alignment and drive geometry that these high-output saws depend on. Sourced directly through authorized Multiquip supply channels, part 37570 is built to the same specification as the component originally installed at the factory. DHS Equipment stocks this genuine OEM part so you can get your saw back on the cut without delay.
Key Features
- Correct Drive Geometry: — Machined to the exact groove profile and diameter spec of the original pulley, ensuring proper belt tracking and tension across all listed saw models.
- Genuine OEM Construction: — Factory-sourced Multiquip part built to the same material and dimensional standards as the pulley originally installed on these pavement saws.
- Broad Pavement Saw Compatibility: — Fits PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 series saws.
- Sustained Blade Power Delivery: — A properly functioning pulley transfers engine torque to the blade drive belt without slippage or vibration, keeping cut depth and speed consistent through hard pavement.
- Direct Drop-In Replacement: — Part 37570 installs in the existing pulley position without machining or adaptation, restoring the drive system to its original configuration.
The drive pulley transmits rotational power from the engine to the blade belt system on a pavement saw. It works in tandem with the belt to control blade speed and torque, and its groove dimensions must precisely match the belt profile to prevent slipping, uneven wear, or loss of cutting force. When a pulley wears, cracks, or develops groove damage, the drive belt loses grip, blade RPM drops inconsistently, and the belt itself deteriorates rapidly — leading to unexpected downtime mid-cut. Replacing a worn pulley with the correct OEM part restores the full drive efficiency the saw was engineered to deliver.
