Multiquip 23757 Hydraulic Pump Drive Pulley 4.58" Dia - OEM Replacement Part

This 4.58" diameter hydraulic pump drive pulley transfers engine power to the hydraulic system that controls the twin trowel rotors on ride-on power trowels. When this pulley wears or fails, you'll experience reduced hydraulic pressure, inconsistent blade speed, or complete loss of rotor control—critical issues that halt finishing operations.

The pulley is a key component in the power transmission system located between the engine and hydraulic pump assembly. During routine maintenance, inspect this pulley for wear, cracks, or belt groove damage. A worn pulley can cause belt slippage, overheating, and premature failure of the hydraulic pump drive belt. Replace immediately if you notice unusual vibration, belt squealing, or visible damage to the pulley surface.

This OEM pulley ensures proper belt alignment and optimal power transfer, maintaining the hydraulic pressure needed for smooth, responsive trowel blade operation during concrete finishing work.
