Diesel Z (2018 - 2024 72" REAR DISCHARGE MODELS ONLY) Part Function & Usage The 602745 pulley plays a critical role in the mower’s belt-driven system. It is used to: Maintain proper belt wrap around blade spindles Control belt tension and prevent slippage Guide belt routing to maintain cutting efficiency Reduce vibration through balanced rotation Allows Mower Deck to Operate at Proper Speed and Torque Ratio with OEM Sized Idler Pulleys - Per Manufacture Specifications Assembly & Installation Direction Disconnect spark plug and remove key before servicing. Lower deck to lowest position and relieve belt tension using the idler tensioner. Note belt routing carefully before removal (take a picture if needed). Rotate spindle assembly and wiggle pulley to determine if spindle assembly bearings are rough, worn, and have excessive play - if so, replace before installing the new pulley (refer to spindle assembly 607407P for Spindle Assembly replacement or help links in rebuilding the spindle assembly). Remove retaining bolt and washer securing pulley to the spindle assembly. Install new pulley with factory spacer orientation intact. Ensure pulley groove faces the belt correctly (belt rides fully inside V-groove). Reinstall bolt using manufacturer torque specification (70 ft-lbs. or 95Nm). Reinstall belt and confirm correct routing on all spindles and guides. Rotate deck by hand to confirm proper tracking before starting engine. Note: Refer to the Images Below and Additional Note and Common Parts Reference for Additional Information. Installation Tips from the Shop If the belt shows glazing or cracking, replace it at the same time. Check all spindle assemblies & idler pulleys for rough bearings while belt is removed. Inspect spindle pulley grooves for wear that may cause belt jump-off. Always verify spacer placement — forgotten spacer placement can cause belt misalignment. After installation, run mower briefly and recheck belt tracking.
