What kind of paper should be used for the crankshaft bearing shim?
1 Answers
Wax paper should be used for the crankshaft bearing shim. The following are the precautions for engine maintenance: 1. The fuel must be clean: If the fuel contains a high amount of impurities, it will accelerate the wear of the electric fuel pump and reduce its service life. Dirty fuel can also cause blockages in the fuel filter and injectors, affecting fuel supply pressure and normal injection volume, thereby reducing the engine's performance. 2. Correct selection of fuel: The engine has high requirements for fuel quality and grade, especially for fuel-injected engines. For cars equipped with catalytic converters and oxygen sensors, only unleaded high-grade gasoline should be used. If leaded gasoline is used, the exhaust catalytic converter will fail after driving more than 400 kilometers, the oxygen sensor will malfunction, and the normal operation of the engine will be affected.
