Securing the Bearing:
Fasteners: Use only the specified high-strength bolts, washers, and nuts as recommended by Caterpillar. These are critical for maintaining proper clamp load.
Lubrication: Lightly lubricate the bolt threads and contact faces of the washers with clean engine oil to ensure accurate and consistent torque application.
Torque Sequence: Tighten the bolts in a star-pattern or cross-sequence in multiple stages (e.g., 50% torque, then 80%, then final 100%). This is crucial to press the bearing evenly onto the mounting surface without causing distortion. Final torque values must be strictly adhered to.
This 171-9380 slewing bearing is used for 312D 313D 312C 312D2 313D 313D2 excavator.
