12. Refill with the specified amount of the recom-
mended engine oil.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher.
 Make sure that no foreign material enters the
crankcase.
13. Check the engine oil filler cap O-ring for dam-
age, and then install the filler cap.
14. Start the engine and let it idle for several min- utes while checking for oil leakage. If any oil
leakage is found, immediately turn the engine
off and check for the cause.
15. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.

an important liquid engine component. We form
teams of specialists in the fields of mechanical en-
gineering, chemistry, electronics and track test-
ing, and have them develop the engine together
with the oil it will use. Yamalube oils take full ad-
vantage of the base oil’s qualities and blend in the
ideal balance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and synthetic oils have their own distinct characters and value.

EBU28568Final 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 level
1. Park the ATV on a level surface. 2. Remove the final gear oil filler bolt and its gas-
ket, and then check the oil level in the final
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 oil filler bolt gasket for damage, and replace it if necessary.
5. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.

To change the final gear oil
1. Park the ATV on a level surface.
2. Remove the final gear case guard by remov- ing the bolts.
3. Place an oil pan under the final gear case to collect the used oil.
4. Remove the final gear oil filler bolt, the final gear oil drain bolt and their gasket to drain the
oil from the final gear case. 5. Install the drain bolt and its new gasket, and
then tighten the bolt to the specified torque.
6. Refill with the recommended final gear oil to the brim of the filler hole as shown. NOTICE:
Be sure no foreign material enters the final
gear case.

gear case may occur when applying the rear
brake.
7. Check the oil filler bolt gasket for damage,
and replace it if necessary.
8. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
9. Check the final gear case for oil leakage. If oil is leaking, check for the cause.

EBU38830Changing the differential 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 must be
changed as follows at the intervals specified in the
periodic maintenance and lubrication chart.

2. Place an oil pan under the differential gear
case to collect the used oil.
3. Remove the differential gear oil filler bolt, the differential gear oil drain bolt and their gasket
to drain the oil from the differential gear case. 4. Install the drain bolt and its new gasket, and
then tighten the bolt to the specified torque.
5. Refill with the specified amount of the recom- mended differential gear oil. NOTICE: Be
sure no foreign material enters the differ-
ential gear case.
[ECB00412]
TIP Do not exceed the specified differential gear oil
quantity when filling. Overfilling will cause the oil
to seep out of the breather hose during and af-
ter riding.
 The differential gear case capacity is greater
than the recommended oil quantity, therefore
the oil level cannot be accurately checked from
the oil filler hole. 6. Check the oil filler bolt gasket for damage,
and replace it if necessary.
7. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
Recommended differential gear oil:
Yamaha Friction Modified Plus Shaft Drive Oil (Part No.: ACC-SHAFT-PL-32) or SAE 80
