Clearance Check
Over time, wear will lead to increased axial and radial clearance in the bearing.
Method: This is a specialized measurement typically performed by a technician. It involves using a dial indicator to measure the free movement (play) between the upper and lower structures.
Action: If the clearance exceeds the maximum allowable limit specified by Caterpillar, the slewing bearing must be replaced to maintain machine stability and precision.
This 227-6092 slewing bearing is used for 330C 336D excavator.
