FOTON AUMAN GTL Front Axle Steering Knuckle Assembly YH01534521M006
Preventive Maintenance
1. Mandatory Periodic Greasing:
• Standard Highway Transport: Grease must be applied every 5,000 to 8,000 kilometers.
• Severe Operating Conditions (e.g., dump trucks, mining operations, or construction sites): Grease must be applied every 3 to 5 days of operation (or every 1,000 kilometers).
2. Special Notes for Maintenance-Free Front Axles:
• If your Auman truck is equipped with ConMet or Hande maintenance-free wheel hub units, the wheel bearings do not require periodic disassembly, cleaning, or maintenance. However, the kingpins and bushings still require regular inspection and the application of grease.
3. Inspection of Air Brake System and Brake Chamber Clearance:
• During every major service, check the bolts securing the brake chamber mounting plate to the steering knuckle to ensure they are not loose; this prevents localized overloading of the steering knuckle during braking.
