5. Insert the dipstick completely into the oil filler
hole, and then remove it again to check the oil
level.
TIPThe engine oil should be between the minimum
and maximum level marks.
6. If the engine oil is at or below the minimumlevel mark, add sufficient oil of the recom-
mended type to raise it to the correct level.
NOTICE: Be sure the engine oil is at the
correct level, otherwise engine damage
may result.

2. Remove the final gear oil level check bolt and
its gasket, and then check the oil level in the
final gear case. The oil level should be at the
brim of the check hole.
3. If the oil is below the brim of the check hole, remove the final gear oil filler bolt and its gas-
ket, and then add sufficient oil of the recom-
mended type to raise it to the correct level. 4. Check the gaskets for damage, and replace
them if necessary.
5. Install the oil level check bolt, the oil filler bolt and their gasket, and then tighten the bolts to
the specified torques.

6. Check the oil level check bolt gasket and the
oil filler bolt gasket for damage, and replace
them if necessary.
7. Install the oil level check bolt, the oil filler bolt and their gasket, and then tighten the bolts to
the specified torques.
8. Check the final gear case for oil leakage. If oil is leaking, check for the cause.
EBU23427Differential gear oilThe differential gear case must be checked for oil
leakage before each ride. If any leakage is found,
have a Yamaha dealer check and repair the ATV.
In addition, the differential gear oil level must be
checked and the oil changed as follows at the in-
tervals specified in the periodic maintenance and
lubrication chart. To check the differential gear oil level
1. Place the ATV on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil level in the
differential gear case. The oil level should be
at the brim of the filler hole.
3. If the oil is below the brim of the filler hole, add sufficient oil of the recommended type to
raise it to the correct level.
4. Check the gasket for damage, and replace it if necessary.
Tightening torques:
Final gear oil level check bolt:10 Nm (1.0 m·kgf, 7.2 ft·lbf)
Final gear oil filler bolt: 23 Nm (2.3 m·kgf, 17 ft·lbf)

WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precautions:

Insufficient brake fluid may allow air to enter
the brake system, reducing braking perfor-
mance.
 Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed contain-
er. 
Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.
 Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Water will
significantly lower the boiling point of the flu-
id and may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately. As the brake pads wear, it is normal for the brake
fluid level to gradually go down. A low brake fluid
level may indicate worn brake pads and/or brake
system leakage; therefore, be sure to check the
brake pads for wear and the brake system for
leakage. If the brake fluid level goes down sud-
denly, have a Yamaha dealer check the cause be-
fore further riding.
