Key Features

• Genuine OEM Pulley Geometry — Machined to the exact groove profile and diameter spec of the original, ensuring correct belt seating and tension on the 3TNE88 engine drive system.
• Direct Drop-In Fitment — Engineered to mount directly to the 3TNE88 engine shaft on STXD6i and HTXD6i trowels, matching original bolt pattern and bore dimensions.
• Confirmed Compatibility — Verified for the STXD6i and HTXD6i hydrostatic ride-on trowel models in the Multiquip lineup.
• Drive System Integrity — A correctly sized and seated V-pulley maintains proper belt alignment and tension, which directly affects hydraulic pump output and blade speed consistency during finishing passes.
• Authorized Multiquip Part — Part number 12940342380 is a genuine Multiquip OEM component, backed by the manufacturer's parts program and sold by an authorized distributor.

The V-pulley is a core component of the engine-to-hydraulic-pump drive system on ride-on trowels. It transfers rotational power from the engine crankshaft to the drive belt, which in turn drives the hydraulic pump that controls blade pitch and machine propulsion. When a pulley becomes worn, cracked, or misaligned, belt slip and premature belt wear follow, leading to inconsistent hydraulic pressure and unreliable blade control. Replacing the pulley with the correct OEM part restores proper belt tracking and ensures the hydraulic system receives steady, consistent power delivery throughout the troweling operation.
