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.

IMPORTANT INFORMATION

EB101030

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.

INFO

CAUTION:

Do not use compressed air to spin the bearings dry. This will damage the bearing surfaces.

EB101050

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 sharpedged corner 2 is positioned opposite the thrust 3 it receives. See sectional view.

CHECKING OF CONNECTIONS

EB801000

CHECKING OF CONNECTIONS

Check the connectors for stains, rust, moisture, etc.

1.Disconnect:

●

Connector

2.Check:

●

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

3.Check:

●

Connector leads Looseness → Bend up the pin 1 and connect the terminals.

GEN

INFO

4.Connect:

●

Connector terminals

NOTE:

The two terminals “click” together.

5.Check:

●

Continuity (using a pocket tester)

NOTE:

●

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.
