The Multiquip 37574 is a genuine OEM Pulley 3.6 6G 3V 1615 Taper designed for Multiquip pavement saw models including PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030. As a direct OEM replacement, part 37574 meets the original engineering specifications for these saws, ensuring the drive system performs exactly as intended. Sourced directly through Multiquip's authorized parts network, this pulley is the correct specification for the 1615 taper bore configuration used across the PS, SP, and CS pavement saw families.
Key Features
- Genuine OEM Taper Bore Specification — Manufactured to the exact 1615 taper bore profile, ensuring correct shaft engagement and torque transfer without slippage or misalignment.
- 3V Three-Groove Belt Compatibility — Configured for 3V triple-groove belt drives, matching the original drive configuration of Multiquip PS, SP, and CS pavement saw models.
- Broad Pavement Saw Fitment — Confirmed fit across PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 models.
- Drive System Integrity — A correctly sized and seated pulley maintains proper belt tension and alignment, protecting both the belts and the blade drive system from premature wear.
- Drop-In Replacement — Matches the original mounting and taper bore dimensions, allowing installation using standard taper-lock tooling with no machining or modification.
A taper-lock pulley transmits engine power through the belt drive system to the saw blade by gripping the shaft via a precision-machined taper bore bushing. The 3V groove profile is sized to work with narrow V-belts, which are common on high-load, compact drive systems like those found in pavement saws. When a pulley wears, cracks, or loses its bore grip, belt slip and vibration increase, which reduces cutting efficiency and can cause rapid belt and bearing failure downstream.
