• Backhoe pivot pins and bushings

• Brake and drive system components

Common Issues & Quick Fixes:

• DPF/DEF Error Codes: Often sensor- or soot-level related; clean DPF and replace faulty sensors with 310L emissions parts

• Boom Drift or Spongy Controls: Caused by worn piston seals — resolve using hydraulic seal kits

• Transmission Lags or Jerky Shifts: Usually a filter issue — service with PowerShift kits

Pro Tips:

• Always check DEF fluid level before long workdays to avoid derates.

• Activate Eco Mode during light-duty tasks to cut fuel consumption up to 10%.

• Regularly torque loader tower bolts — vibration fatigue is a known issue over time.
