NOTICE: Be sure the engine oil is at the
correct level, otherwise engine damage
may result.

Make sure that no foreign material enters the
crankcase.
13. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
14. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.
15. Install the access cover by turning it clock- wise.EBU27308Final gear oilThe final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals speci-
fied in the periodic maintenance and lubrication
chart.
To check the final gear oil level1. Park the ATV on a level surface. 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.

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. To change the final gear oil
1. Park the ATV on a level surface.
2. Place an oil pan under the final gear case to collect the used oil.
3. Remove the final gear oil filler bolt, the final gear oil level check bolt, the final gear oil drain
bolt and their gasket to drain the oil from the
final gear case.
