2006 YAMAHA KODIAK 450 Differential

4-33
NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator light will flash until
the differential gear is locked.


When the indicator light is flashing, turning
the handlebar back and forth will help the dif-
ferential gear lock to engage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
light is flashing) will cause the engine speed
to be limited until engagement is complete.


When the ATV is in 4WD-LOCK, the maxi-
mum traveling speed is limited to 35 km/h.
However, if conditions require full engine
power to be available, push and hold the
override switch to disable the 4WD-LOCK
speed limiter. (See pages 4-21–4-23 for a de-
tailed explanation of this switch.)

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)
