Maintenance notice
The parts that are washed should proceed thru relevant examination work
．
The purpose is to confirm that the part whether
it needs repair or replace
．
The examination method is divided into three methods include direct examination
，
testing
examination and detecting examination
Direct examination method
This method does not need instrument and other tools
，
it checks and determines the technologic state of part just
according to the sense organs of human being
．
The way is simple and easy to use
，
it is used wide in motorcycle
maintenance.
Testing examination method
This way is a way that test the size of part and change of geometric form with gauge and instrument
，
and make contrast to
the allowed limit with the data to confirm the technologic state of part
．
The accuracy of this way is high
，
but before test
should check the precision of gauge and instrument carefully and choose the testing position reasonably.
Detecting examination method
This way can test the invisible flaws of part
．
In motorcycle maintenance, generally adopt the best easy way--dipping oil to
beat by hammer
，
that means putting the parts into coal oil or diesel oil to soak several minutes then take out and wipe the
surface
，
spread talcum powder on the surface of parts uniformly
，
beat its nonworking sue face lightly by small hammer.
owing to beating will cause versatility of part, if part has crack
，
then the oil sludge that dipped into crack originally will
splash due to beating and versatility
，
then the talcum powder on surface will be dyed yellow
，
so one yellow line will be
