How to Repair Oil Leakage in Diesel Engine Air Pump?
2 Answers
It cannot be repaired, only a new air pump can be replaced. The following are precautions for diesel engine air pumps: 1. Seasonal maintenance: The maintenance of diesel engine air pumps should be carried out according to the season and temperature. When the temperature is too low in winter, it is necessary to add antifreeze to the cooling system; when the temperature remains low for a long time, kerosene can be added to the diesel. 2. Lubrication of the diesel engine: The diesel engine requires its first oil change after 40 hours of initial operation, and the oil change cycle is determined based on its usage and oil quality. If the diesel pump has been idle for too long, it should be replaced before use.
Hey, I've dealt with diesel engine air pump oil leakage several times. Most cases are due to aging seals or piston wear at the oil seal area, allowing oil to seep into the air system. I suggest you first stop and check if the oil level is normal - if it's too high, drain some. If it's just a failed seal, you can DIY replace it with a new one, choosing high-quality rubber parts - don't cheap out to avoid repeated failures. But if you find cylinder liner scratches or severe wear, you'll need professional mechanics who can perform precise testing and replacement. Remember, oil leakage contaminates the air system and affects braking performance, so make sure it's fixed before long trips. Regular maintenance should include monitoring oil condition and cleaning surrounding areas during oil changes to extend service life.
