IMPORTANT INFORMATION I ~~~ I~I 1E011 IMPORTANT INFORMATION PREPARATION FOR REMOVAL AND DIS- ASSEMBLY 1. Remove all dirt, mud, dust, and foreign material before removal and disassembly. While cleaning, take care to protect the electrical parts, such as relays, switches, motor, resistors, controllers, etc., from high pressure water splashes. 2. Use proper tools and cleaning equipment. Refer to "SPECIAL TOOLS" . 3. When disassembling the machine, keep mated parts together. This includes gears, cylinders, pistons, and other parts that have been "mated" through normal wear. Mated parts must be reused as an assembly or replaced. 4. During disassembly of the machine, clean all parts and place them in trays in the order of disassembly. This will speed up assembly time and help ensure that all parts are rein- stalled correctly. 5. Keep away from fire. 6. Be sure to keep to tightening torque specifications. When tightening bolts, nuts, and screws, start with larger-diameter pieces, and proceed from an inner-positioned one to an outer-positioned one in a criss-cross pattern. 1-2

IMPORTANT INFORMATION II~~~ I~I ALL REPLACEMENT PARTS 1.We recommend use of Yamaha genuine parts for all replacements. Use oil and/or grease recommended by Yamaha for assembly and adjustment. GASKETS, OIL SEALS, AND O-RINGS 1. All gaskets, seals, and a-rings should be replaced when an engine is overhauled. All gasket surfaces, oil seal lips, and a-rings must be cleaned. 2. Properly oil all mating parts and bearings during reassembly. Apply grease to the oil seal lips. .. 300-000 300-002 300-003 1-3 LOCK WASHERS/PLATES AND COTTER PINS 1. All lock washers/plates CD and cotter pins must be replaced when they are removed. Lock tabts) should be bent along the bolt or nut tlatts) after the bolt or nut has been properly tightened. BEARINGS AND OIL SEALS 1.lnstall the bearing(s) CD and oil sealts) ® with their manufacturer's marks or numbers facing outwards. (In other words, the stamped letters must be on the side exposed to view.) When installing ollseatts). apply a light coating of lightweight lithium base grease to the seal lipts). Oil the bearings liberally when installing. '._1, _ Do not use compressed air to spin the bearings dry. This causes damage to the surface of the bearings.

IMPORTANT INFORMATION/SPECIAL TOOLS II~~~ I~I CIRCLIPS 1.All circlips should be inspected carefully before reassembly. Always replace piston pin clips after one use. Replace misshapen circlips. When installing acirclip CD, make sure that the sharp edged corner ® is positioned opposite to the thrust @ it receives. See the sectional view. 300-001 @ Shaft 1E021 SPECIAL TOOLS Some special tools are necessary for completely accurate tune-up and assembly.
