. 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 where 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.
