IMPORTANT INSTALLATION NOTES:
✔ Confirm the 7.08" pulley diameter, 4V belt configuration, and 2.32" first-groove position against the removed clutch.
✔ Confirm the exact chassis and Caterpillar 3406 configuration because ATAAC and non-ATAAC cooling packages may use different pulley or mounting arrangements.
✔ Inspect the fan blades, belts, pulley, mounting bracket, air line, and fan-control valve for wear or damage.
✔ Align all four belt grooves correctly and torque the fan, clutch, and mounting hardware to Horton or vehicle-manufacturer specifications.
✔ Verify belt tracking, fan clearance, air-system sealing, and correct clutch engagement and disengagement.
