Maintenance instructions
This section describes the engine lubrication system and the cleaning, inspection, and
replacement of various parts of the system. The engine should not be removed when
inspecting and cleaning the lubrication system, but the oil in the engine should be drained
before inspection and cleaning.
5.2.1Troubleshooting
First, the lubricant is consumed too fast
1. The engine has oil leakage
2, piston ring wear
3, the intake and exhaust valve guides
wear
4. The oil hood is worn or damaged
Second, the lubricant is not clean
1. The engine oil is not replaced
according to the maintenance schedule.
2, the oil filler thread is damaged
Third, the lubrication is not normal
1, the oil level is too low
2, oil passage or filter blockage
3, the oil pump is damaged.
5.2.2Engine lubrication system
Lubricating oil is an important factor
affecting engine performance and life. It
must be selected according to regulations.
It cannot be replaced by ordinary engine
oil, gear oil, vegetable oil, etc.
When the car is shipped from the factory,
it is filled with 15W/40SE gasoline engine
oil. If you switch to other lubricants (the
best oil for Longxin), the quality grade
should reach QE or SF. The viscosity
should be selected according to the different regions and temperature changes.
When replacing the lubricating oil, please
put out the original lubricating oil in the
crankcase, clean it with washing kerosene,
and then add new lubricating oil
according to the regulations
