CAT 064-1489 BEARING

CAT 064-1489 is a Caterpillar genuine single-row deep groove ball bearing (pure original factory information, no additional description), adapted for the hydraulic pump drive end and accessory drive shaft of C7/C9 engines, used for radial load support and high-speed stable rotation. It is used in conjunction with the 064-0560 retainer and the 064-0974 oil retainer ring to ensure the accuracy and lifespan of the transmission system.

Installation and maintenance points:
Clean the journal and bearing housing bore, ensuring no burrs or oil contamination. Check the bearing seal and cage for integrity, deformation, or damage.

Cold press the bearing journal (using specialized tooling to avoid impact). Install the outer ring into the bearing housing. Position the retainer assembly and tighten the screws (torque 9-11 N·m).

Inspection: The bearing should rotate freely without jamming. Radial clearance should be 0.015-0.028 mm, axial runout ≤0.15 mm, and there should be no abnormal noise.

Maintenance: Check the retainer screw torque every 2000 hours. Disassemble every 5000 hours. Replace the seal if damaged or if the rolling elements are pitted to prevent lubrication failure.
