Detailed Maintenance Procedures
Follow these structured procedures to ensure thorough preventive maintenance of your dump truck. Adapt these steps to your specific truck model and operating conditions.
Hydraulic System Maintenance
- Park on level ground and engage parking brake
- Allow hydraulic system to cool before checking fluid level
- Clean area around fill cap before removing
- Check fluid level with hoist cylinders fully retracted
- Take oil sample for analysis before fluid replacement
- Replace filters according to maintenance schedule
- Inspect all hydraulic lines for chafing or damage
Brake System Inspection
- Check air system pressure buildup time (< 2 minutes)
- Drain air tanks and check for excessive moisture
- Measure brake shoe/pad thickness (minimum 1/4")
- Inspect brake drums/rotors for cracks or scoring
- Check slack adjuster free travel (1/2" - 3/4")
- Test parking brake holding capability on grade
- Verify ABS system function if equipped
Engine Service Protocol
- Change engine oil when warm for better draining
- Replace oil filter and clean mounting base
- Inspect air filter and clean housing
- Replace fuel filters and prime system
- Check/adjust valve clearance per specifications
