. MAINTENANCE SPECIFICATIONS
The basic methods of motorcycle maintenance include inspection, adjustment, tightening,
lubrication, cleaning, supplementing and replacement, which constitute the main elements of
maintenance.
1.
Inspection
Inspection refers to basic inspecting operations in accordance with items and
requirements specified in the user’s manual, including inspection with instruments or
with eyes for abnormalities in machine parts, directly comparing related data and
aligning with tools and gauges.
2.
Adjustment
Adjustment refers to inspection-based adjustment and rectification of some specified
machine parts, including adjustment of machine part plays and rectification of
misfittings and deformations so as to restore correct positions, forms and plays.
3.
Tightening
Tightening refers tightening of bolts, screws and nuts of machine parts with tools so as
to avoid loosening of machine parts and to obtain specified tightening torques.
4.
Cleaning
Cleaning is needed by machine parts and positions which call for cleanliness and
tidiness. Cleaning operations include all the means and measures taken to remove dust,
contamination, metal chips, oily stains and carbon deposits that might lead to pipe
clogging or reduction in motorcycle performance. Cleaning measures are washing,
carbon deposit removing, rubbing, cleaning and clearing.
5.
Lubrication
In order to facilitate smooth and easy running of moving machine parts, including
swinging parts, reciprocating parts, sliding parts and vibrating parts, to reduce scuffing,
abrasion, deformation and to reduce friction, it is necessary to coat or spray these parts
with a lubricant. Different lubricants and lubricating methods are required for different
machine parts with different functions. Application of lubricants to machine parts is
known as lubrication.
6.
Replenishing, supplement and replacement
These operations refer to addition of oil, lubricants, cooling water, electrolyte, fuel and
replacement of damaged parts with new ones and replacement of denatured oils with
new oils.
