Final Checks and Reassembly:
After torquing, recheck the torque of a few random bolts to ensure consistency.
Reattach the upper structure to the undercarriage, following the reverse of the removal process and ensuring all connections are secure.
Gear Backlash Check: After reassembly, it is good practice to check the backlash between the swing motor pinion gear and the slewing bearing internal gear using a dial indicator. Adjust if necessary to the specification in the service manual.
Lubricate: Fill the new bearing with the specified grease, rotating the machine several times to ensure proper distribution.
This 227-6142 slewing bearing is used for 323D 320D 320C excavator.
