The connection between the supercharger of the flatbed truck and the intake and exhaust pipes must be tight and not leak.

The maintenance of the flatbed truck should pay attention to the following points:
1. The connection between the supercharger and the intake and exhaust pipes of the flatbed truck must be tight and can not leak air. If there is air leakage between the exhaust pipe and the exhaust gas turbine, the efficiency of the supercharger will be greatly reduced, and the exhaust temperature of the diesel engine will rise sharply. And damage the valve and supercharger.
2. Before starting the new engine, the supercharger and supercharger oil filter must be filled with clean oil to ensure that the diesel engine starts together and the supercharger bearing can be lubricated. After the car travels 8,000 to 10,000 km, the oil filter element of the supercharger must be replaced.
3. Before the diesel engine stops, the flatbed truck should run for 3 to 5 minutes at idle speed to reduce the speed of the supercharger and the temperature, and monitor the running sound of the supercharger. If any abnormality is found, it should be stopped for inspection. If the rotor of the turbocharger is inflexible, there is sticking or wear noise, it must be sent to a qualified repair station for repair.
4. For the flatbed truck, after every 500h or 30,000km of operation, check the clearance on the supercharger rotor shaft, and remove the dust and carbon deposits on the compressor turbine casing and rotor blades. At this point, the turbocharger should be removed from the diesel engine and the metal gasket between the exhaust pipes of the supercharger should be replaced. It is not allowed to use mechanical means to remove the scale on the rotor parts, but use gasoline or other cleaning solutions for cleaning aluminum parts
5. The lock nut of the supercharger compressor of the flatbed truck cannot be disassembled, otherwise the dynamic balance of the supercharger rotor will be destroyed and the supercharger will be damaged.
6 For the flatbed transporter, do not damage or deform the rotating parts of the turbocharger that has been removed, otherwise it will affect the balance of the flatbed transporter's turbine. Likewise, any rubber seals must not be damaged.
