Technical Notes

Journal bearings support the turbo shaft and require careful handling during reassembly. For Komatsu D155 applications, verify the bearing dimensions and shaft interface against your existing unit. Ensure the bearing surface is clean and free of debris before installation. Check for any scoring or wear on the shaft that could affect alignment. Proper lubrication is essential for stable operation and to prevent premature wear. If the bearing housing shows signs of damage, consider replacing the entire housing assembly.
