Pump Drive Crankshaft Pulley for Hydraulic System (B Belt) SKU: 433-0002-00

When your hydraulic drive system loses power transfer to the pump, it's often traced back to a cracked or worn crankshaft pulley. This pulley mounts directly on the engine crankshaft and provides the critical power link to your hydraulic pump via the B-section drive belt, keeping your machine moving smoothly under load.

Why Genuine Spartan Matters

• Engineered for precise B-belt alignment and consistent hydraulic pump drive
• Built to handle constant rotation, vibration, and power transfer demands
• Proper crankshaft keyway fit prevents slipping and premature wear
• Factory specifications ensure optimal belt tracking and system performance

A worn or damaged crankshaft pulley creates hydraulic system problems that get expensive fast—belt slippage, reduced pump pressure, and eventual component failure. This genuine Spartan replacement restores the reliable power transfer your hydraulic system depends on. When you need it right the first time, S&H Parts has served equipment owners since 1969.
