- 2. E NOTICE This manual has been prepared by the Yamaha Motor Company Ltd. primarily for use by Yamaha dealers and their trained mechanics when performing maintenance procedures and repairs to Yamaha equipment. It has been written to suit the needs of persons who have a basic understanding of the mechanical and electrical concepts and procedures inherent in the work, for without such knowledge attempted repairs or service to the equipment could render it unsafe or unfit for use. Because the Yamaha Motor Company Ltd. has a policy of continuously improving its prod- ucts, models may differ in detail from the descriptions and illustrations given in this publica- tion. Use only the latest edition of this manual. Authorized Yamaha dealers are notified periodically of modifications and significant changes in specifications and procedures, and these are incorporated in successive editions of this manual.

- 3. E A50000-0 HOW TO USE THIS MANUAL MANUAL FORMAT This manual provides the mechanic with descriptions of the operations of disassembly, repair, assembly, adjustment and inspection, each of which is presented in a sequential, step- by-step procedure. To assist you to find your way about this manual, the Section Title and Major Heading is given at the head of every page. An Index to contents is provided on the first page of each section. MODEL INDICATION Multiple models are shown in this manual. These indications are noted as follows. THE ILLUSTRATIONS Some illustrations in this manual may differ from the model you have. This is because the procedure described may relate to several models, though only one may be illustrated. (The name of the model described will be mentioned in the description.) To help you identify components and understand the correct procedures of disassembly and assembly, exploded diagrams are provided. Steps in the procedures are numbered thus: 1), 2), 3). Parts shown in the illustrations are identified thus: 1, 2, 3. REFERENCES These have been kept to a minimum, however, when you are referred to another section of the manual, you are told the page number to go to.

- 11. 1-2 GEN INFO ESAFETY WHILE WORKING SAFETY WHILE WORKING The procedures given in this manual are those recommended by Yamaha to be fol- lowed by Yamaha dealers and their mechanics. FIRE PREVENTION Gasoline (petrol) is highly flammable. Petroleum vapor is explosive if ignited. Do not smoke while handling and keep it away from heat, sparks, and open flames. VENTILATION Petroleum vapor is heavier than air and if inhaled in large quantities will not support life. Engine exhaust gases are harmful to breathe. When test-running an engine indoors, maintain good ventilation. SELF-PROTECTION Protect your eyes with suitable safety glasses or safety goggles when using com- pressed air, when grinding or when doing any operation which may cause particles to fly off. Protect hands and feet by wearing safety gloves or protective shoes if appropriate to the work you are doing. OILS, GREASES AND SEALING FLUIDS Use only genuine Yamaha oils, grease and sealing fluids or those recommended by Yamaha.
- 12. 1-3 GEN INFO ESAFETY WHILE WORKING Under normal conditions of use, there should be no hazards from the use of the lubricants mentioned in this manual. How- ever, safety is all-important and by adopt- ing good safety practices, any risk is minimized. A summary of the most important precau- tions is as follows: 1. While working, maintain good stan- dards of personal and industrial hygiene. 2. Clothing which has become contami- nated with lubricants should be changed as soon as practicable, and laundered before further use. 3. Avoid skin contact with lubricants; do not, for example, place a soiled wiping- rag in one’s pocket. 4. Hands, and any other part of the body which have been in contact with lubri- cants or lubricant-contaminated cloth- ing, should be thoroughly washed with hot water and soap as soon as practica- ble. 5. To protect the skin, the application of a suitable barrier cream to the hands before working is recommended. 6. A supply of clean, lint-free cloths should be available for wiping purposes. GOOD WORKING PRACTICES 1. The right tools Use the special tools that are advised to protect parts from damage. Use the right tool in the right manner - don’t improvise. 2. Tightening torque Follow the torque tightening instruc- tions. When tightening bolts, nuts and screws, tighten the larger sizes first, and tighten inner-positioned fixings before outer-positioned ones.
- 13. 1-4 GEN INFO ESAFETY WHILE WORKING 3. Non-reusable items When reassembling, always use new gaskets, packing, O-rings, oil seals, split-pins and circlips, etc. DISASSEMBLY AND ASSEMBLY 1. Clean parts with compressed-air when disassembling them. 2. Oil the contact surfaces of moving parts before assembly. 3. After assembly, check that moving parts operate normally. 4. Install bearings with the manufacturer’s markings on the side exposed to view and liberally oil the bearings. 5. When installing oil seals, apply a light coating of water-resistant grease to the outside circumference.
- 14. 1-5 GEN INFO ESPECIAL TOOLS A80000-0* SPECIAL TOOLS The use of correct special tools recommended by Yamaha will aid the work and enable accu- rate assembly and tune-up. Improvisations and use of improper tools can cause damage to the equipment. NOTE: q For USA and Canada, use part numbers starting with “YB-”, “YM-”, “YU-” or “YW-”. q For others, use part numbers starting with “90890-”.
