The air dryer assembly 3511010-73A / LG9700360081 is a critical safety component for the pneumatic systems of HOWO, FAW, Foton, and Shacman trucks. Based on our field experience, this assembly effectively removes moisture and oil contaminants from the compressed air, preventing corrosion and ice formation within the brake lines. Featuring an integrated pressure regulator and a desiccant cartridge, the 3511010-73A assembly ensures that clean, dry air is distributed to the storage reservoirs and braking circuits.
Mechanic's Expert Advice: A failing air dryer usually manifests as water buildup in air tanks or frequent pressure relief valve cycling. If moisture reaches the brake valves, it leads to internal seal failure. Installation Tip: When installing the LG9700360081 assembly, verify that the heating element is functioning correctly to prevent freeze-ups during winter operations. We strongly advise replacing the desiccant cartridge twice a year. Keeping the air dryer in top condition is the most cost-effective way to protect the entire pneumatic system and ensure reliable braking performance in all climates.
