machine repair. Repairs attempted by anyone without this knowledge are likely to render the
machine unsafe and unfit for use.
Yamaha Motor Company, Ltd. is continually striving to improve all its models. Modifications and
significant changes in specifications or procedures will be forwarded to all authorized Yamaha
dealers and will appear in future editions of this manual where applicable.
OTE:
Designs and specifications are subject to change without notice.

IMPORTANT INFORMATION
PREPARATION FOR REMOVAL
PROCEDURES
1.Remove all dirt, mud, dust and foreign
material before removal and disassembly.
2.Use proper tools and cleaning equipment.
Refer to the “SPECIAL TOOLS” section.
3.When disassembling the machine, always
keep mated parts together. This includes
gears, cylinder, piston and other parts that
have been “mated” through normal wear.
Mated parts must always be reused or
replaced as an assembly.
4.During machine disassembly, clean all 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.
GEN
INFO
EB101010
REPLACEMENT PARTS
1.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.
EB101020
GASKETS, OIL SEALS AND O-RINGS
1.Replace all gaskets, seals and O-rings when
overhauling the engine. All gasket surfaces,
oil seal lips and O-rings must be cleaned.
2.Properly oil all mating parts and bearings
during reassembly. Apply grease to the oil
seal lips.

LOCK WASHERS/PLATES AND COTTER
PINS
1.Replace all lock washers/plates 1 and cotter
pins after removal. Bend lock tabs along the
bolt or nut flats after the bolt or nut has been
tightened to specification.
EB101040
BEARINGS AND OIL SEALS
1.Install bearings and oil seals so that the
manufacturer’s marks or numbers are visible.
When installing oil seals, apply a light
coating of lightweight lithium base grease to
the seal lips. Oil bearings liberally when
installing, if appropriate.

CIRCLIPS
1.Check all circlips carefully before
reassembly. Always replace piston pin clips
after one use. Replace distorted circlips.
When installing a circlip 1, make sure that
the sharp-edged corner 2 is positioned
opposite the thrust 3 it receives. See
sectional view.

Moisture → Dry each terminal with an air
blower.
Stains/rust → Connect and disconnect the
terminals several times.
3.Check:
●

OTE:
●
If there is no continuity, clean the terminals.
●
When checking the wire harness be sure to
perform steps 1 to 3.
●
As a quick remedy, use a contact revitalizer
available at most part stores.
●
Check the connector with a pocket tester as
shown.
