GENERAL RULES OF SERVICING WORK
1. Preparation before disassembly
• Prepare necessary mechanic tools, measuring instruments and SST before starting operation.
• When disassembling a complicated assembly, put punch or matching marks at places not affecting the
function to facilitate reassembly operation. When repairing an electrical system, start operation after
disconnecting the cable from the battery negative terminal.
2. Inspection during disassembly
• Each time a part is removed, check the part installed state, deformation, damage, roughening state and
scratching.
3. Orderly arrangement of disassembled parts
• Disassembled parts shall be arranged orderly. Distinguish the parts to be replaced from the parts to be reused.
4. Cleaning of disassembled parts
• Parts to be reused shall be cleaned and washed thoroughly.
5. Inspection and measurement
• Detailed inspection and measurement shall be carried out as required for parts to be reused.
6. Installation
• Install good parts according to the correct procedure and observing the determined standards (tightening
torques, adjustment values, etc.).
• Be sure to use genuine parts for replacement of existing parts.
• Be sure to use new packings, gaskets and cotter pins because they are non-reusable parts.
• Coat seal packing on gaskets depending on the places, coat oil on the sliding contact places, coat oil or
grease at specified places, and coat MP grease on oil seal lips before reassembly.
7. Adjustment and operation check
• Adjust to the service standard values by using gages, a multimeter, etc.
