Pump Drive Idler Pulley for Spartan Mower Hydraulic Systems SKU: 433-0013-00

A worn or misaligned pump drive idler pulley causes real problems in your hydraulic system—belt slippage that reduces pump flow, excessive belt wear from poor tracking, and uneven drive loads that can damage your hydraulic pump. This 5-3/4 inch steel idler pulley restores proper belt routing and maintains the precise tension your Spartan mower's pump drive system needs.

Why This Pulley Matters

• 5-3/4 inch diameter provides exact belt path geometry for consistent hydraulic performance
• Precision steel construction withstands the constant flexing and load changes of mowing operations
• Flat pulley design ensures smooth belt contact without side-loading that causes premature wear
• Maintains critical belt tension that prevents pump cavitation and power loss

When your mower's hydraulics feel sluggish or you're burning through drive belts too quickly, this idler pulley gets your system back to factory performance. S&H Parts has been helping customers solve hydraulic drive issues since 1969.
