What are the maintenance items for heavy-duty trucks?
1 Answers
Maintenance items for heavy-duty trucks are as follows: 1. Oil and filter replacement: Change the engine oil along with three filters - oil filter, air filter, and diesel filter; 2. Wheel hub maintenance: Due to their heavy load capacity, large trucks use tapered bearings which require high-grade grease; 3. Transmission oil change: The transmissions of heavy-duty trucks experience significant wear from overloaded operations, requiring regular gear oil changes to minimize wear. The rear axle differential operates similarly to the transmission - typically requiring one gear oil change for every two engine oil changes.
