Truck Air Spring Maintenance Guide (Daily & Periodic)
| Maintenance Type | Inspection/Maintenance Item | Specific Operations and Standards | Precautions |
| I. Daily & Weekly Checks | 1. Visual Inspection | • Air Spring Body: Check the surface for cracks, cuts, bulges, abnormal wear, or oil stains.
• Peripheral Clearance: Ensure there is no contact or friction between the air spring and components like the frame or leaf springs.
• Mounting Points: Check if the upper and lower base mounting bolts are tight. | Fine cracks indicate aging, while cuts and bulges require immediate attention. |
| 2. Operational Status Check | • Listen for Leaks: Listen for obvious hissing sounds when the vehicle starts and the air system pressurizes.
• Observe Vehicle Height: Check if the vehicle is level on both sides when unloaded and loaded.
• Soap Water Leak Test: Spray soapy water on suspected areas (air spring, connections) and observe for bubbles. | One side sitting low typically indicates a fault with that air spring or leveling valve. The soapy water test is the most effective method for locating leaks. |
| II. Periodic Maintenance & In-Depth Checks | 1. Cleaning Maintenance | • Clean the air spring surface with water and neutral soap to remove dirt, mud, and salt.
• Allow it to air dry naturally after cleaning. | Strictly avoid using strong chemical solvents like gasoline or thinners. Avoid direct close-range spraying with high-pressure washers. |
| 2. Related System Checks | • Air Dryer: Replace the filter cartridge regularly to ensure a dry and clean air supply.
• Lines & Connections: Check all air lines for aging, cracking, wear, and ensure connections are secure.
• Leveling Valve: Check if the linkage operates smoothly without sticking; manually actuate it to listen for inflating/deflating sounds to assess its operation. | Moist, oily air severely damages the entire air system. A stuck leveling valve causes incorrect ride height and air spring damage. |
