Hello, the diesel generator is leaking oil because the vacuum booster pump of the diesel vehicle is behind the generator, which is lubricated by the engine oil. Engine oil is leaking inside and the seal is broken. If you need to replace the alternator, for your reference, if there is any problem with the car, ask the car master. Professional technicians from 4S stores can solve the problem within 10 minutes.
I'm not from Baoding, so I don't need to repair it in a 4S store, it's too expensive.
For a service at an auto repair shop in Heilongjiang, 5,000 yuan is enough and everything can be replaced. (Timing belt, all belts, valve grinding, pump calibration 200 yuan, bushing replacement, circuit). It is estimated that the price will not be much different. The maintenance costs and accessories of refined diesel are expensive.
The connection between thegenerator and bodywork should be carefully checked (all Ruifeng diesels have this problem). If it is loose, it must be replaced or aluminum welded. This part is so damaged that the generator may fall down in severe cases. I had this problem with my car.
