Because an off-road vehicle is subjected to tremendous heat, stress and vibration, preventive maintenance prevents costly and untimely corrective maintenance.

By maintaining a routine service schedule as described in this chapter, costly mechanical problems and unexpected breakdowns can be prevented.

The last thing you want is to have a weekend ride cut short because your vehicle broke down in the boonies. Unless the cause is minor, you may be forced to trailer your vehicle home.

The more you get involved with your Yamaha the more you will want to work on it. Start out by doing simple tune-up, lubrication and maintenance. Tackle more involved jobs as you gain experience.

This chapter explains lubrication, maintenance and tune-up procedures required for the Yamaha models covered in this manual. Table 1 is a suggested factory maintenance schedule. Tables 1-8 are located at the end of this chapter.

This chapter describes removal, inspection and installation of the clutch, transmission, and shift mechanism (external and internal) assemblies.

Table 1 (clutch wear limits) and Table 2 (clutch tightening torques) are found at the end of the chapter.


CLUTCH

All models in this manual use both a centrifugal and manual clutch mechanism to transmit power from the engine to the transmission. All clutch types are immersed in the oil supply they share with the engine and transmission.

During disassembly pay particular attention to the location and positioning of spacers and washers to make assembly easier.

Both clutch units can be removed with the engine in the frame.
