Differential gear oil
Checking the differential gear oil
1. Place the ATV on a level surface.
2. Remove the differential gear oil filler bolt and
check the oil level. It should be up to the brim
of the filler hole. If the level is low, add suffi-
cient oil of the recommended type to raise it
to the specified level.CAUTION:_ Be sure no foreign material enters the differen-
tial gear case. _3. Install the differential gear oil filler bolt, and
then tighten it to the specified torque.
Tightening torque:
Differential gear oil filler bolt:
23 Nm (2.3 m·kgf)

Replacing the differential gear oil
1. Place the ATV on a level surface.
2. Place a container under the differential gear
case to collect the used oil.
3. Remove the differential gear oil filler bolt and
differential gear oil drain bolt to drain the oil.
4. Install the differential gear oil drain bolt and
tighten it to the specified torque.

5. Fill the differential gear case with the recom-
mended oil.CAUTION:_ Be sure no foreign material enters the differen-
tial gear case. _6. Install the differential gear oil filler bolt, and
then tighten it to the specified torque.

side, and then drain the coolant from the
coolant reservoir.
9. After draining the coolant, thoroughly flush
the cooling system with clean tap water.

a.Écartement des électrodes
a. Huelgo de la bujía
Installation
1. Measure the electrode gap with a wire thick-
ness gauge and, if necessary, adjust the gap
to specification.
2. Clean the gasket surface. Wipe off any grime
from the threads.
3. Install the spark plug and tighten it to the
specified torque.NOTE:_ If a torque wrench is not available when you are in-
stalling a spark plug, a good estimate of the correct
torque is 1/4 to 1/2 turn past finger tight. Have the
spark plug tightened to the specified torque as
soon as possible. _4. Install the spark plug cap.
5. Install the panel.Spark plug gap:
0.8–0.9 mm
Tightening torque:
Spark plug:
17.5 Nm (1.75 m·kgf)
