IMPORTANT INFORMATION

PREPARATION FOR REMOVAL AND
DISASSEMBLY
1. Before removal and disassembly, remove all
dirt, mud, dust and foreign material.
2. Use only the proper tools and cleaning
equipment.
Refer to "SPECIAL TOOLS" on page 1-8.
3. When disassembling, always keep mated
parts together. This includes gears, cylinders,
pistons and other parts that have been "mated"
through normal wear. Mated parts must always
be reused or replaced as an assembly.
4. During disassembly, clean all of the parts and
place them in trays in the order of disassembly.
This will speed up assembly and allow for the
correct installation of all parts.
5. Keep all parts away from any source of fire.

REPLACEMENT PARTS

Use only genuine Yamaha parts for all
replacements. Use oil and grease recommended
by Yamaha for all lubrication jobs. Other brands
may be similar in function and appearance, but
inferior in quality.
IMPORTANT INFORMATION

GASKETS, OIL SEALS AND O-RINGS

1. When overhauling the engine, replace all
gaskets, seals and O-rings. All gasket
surfaces, oil seal lips and O-rings must be
cleaned.
2. During reassembly, properly oil all mating
parts and bearings and lubricate the oil
seallips with grease.
LOCK WASHERS/PLATES AND COTTER
PINS
After removal, replace all lock washers/plates "1"
and cotter pins. After the bolt or nut has been
tightened to specification, bend the lock tabs
along a flat of the bolt or nut.
