ward.EBU3543AEngine oil and oil filterCheck the engine oil level before each opera-
tion. In addition, change the oil and the oil fil-
ter cartridge at the intervals specified in the
periodic maintenance chart.
NOTICEECB03020 Do not use oils with a diesel specifica-
tion of “CD” or oils of a higher quality
than specified. In addition, do not use
oils labeled “ENERGY CONSERVING II”
or higher.
Make sure that no foreign material en-
ters the oil tank. To check the engine oil level
1. Park the vehicle on a level surface.
2. Remove panel D. (See page 8-11.)
3. Start the engine and warm it up to a nor- mal operating temperature (the engine oil
temperature should reach 60 °C [140 °F]),
then let the engine idle for a minimum of
ten seconds before turning the engine off.TIPIf the engine is cold, take the vehicle for a
short drive or let it idle for approximately ten
minutes before checking the engine oil level.
Recommended engine oil:YA M A L U B E5W-30, 10W-30, 10W-40, 15W-40, 20W-
40, 20W-50
Oil quantity: Oil change only:2.50 L (2.64 US qt, 2.20 Imp.qt)

6. Check the O-ring for damage, and re-place it if necessary.
7. Refill the transmission with the specified amount of the recommended oil.
8. Install the transmission oil filler cap.
9. Start the engine and let it idle while checking for oil leakage.
10. Stop the engine and check the oil level one last time.EBU36053Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication chart.
NOTICEECB03590When checking or changing the final gear
oil, make sure that no foreign material en-
ters the final gear case. If necessary, clean
the final gear oil filler bolt and surrounding
area. TIPIf the recommended gear oil is not available,
SAE 80W-90 API GL-4 or GL-5 hypoid gear
oil may be used instead. Checking the final gear oil level1. Park the vehicle on a level surface.
Tightening torque: Transmission oil drain bolt:20 N·m (2.0 kgf·m, 15 lb·ft)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Oil quantity: 0.47 L (0.50 US qt, 0.41 Imp.qt)

4. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque.
5. Refill with the recommended final gear oil up to the brim of the filler hole.
6. Check the oil filler bolt gasket for dam- age, and replace it if necessary. 7. Install the oil filler bolt and its gasket, and
then tighten the bolt to the specified
torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.
EBU36063Differential gear oilCheck the oil level and change the differential
gear oil at the intervals specified in the gener-
al maintenance and lubrication chart.NOTICEECB03600When checking or changing the differen-
tial gear oil, make sure that no foreign ma-
terial enters the differential gear case. If
necessary, clean the differential gear oil
filler bolt and surrounding area.

To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.
EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine.

TIPIf a torque wrench is not available when in-
stalling the spark plug, a good estimate of the
correct torque is 1/4–1/2 turn past finger tight.
However, the spark plug should be tightened
to the specified torque as soon as possible. NOTICEECB02900Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler may be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the cap
fits tightly. To remove the spark plug cap,
simply twist it back and forth while pulling
it out; to install it, twist it back and forth
while pushing it in.
EBU38320Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
The primary air filter is easily accessed and
should be cleaned and oiled every 300–600
km (200–400 mi).
The secondary air filter is more difficult to ac-
cess, cannot be cleaned, and should be re-
placed by a Yamaha dealer every 2000–5000
km (1200–3000 mi).1. Primary air filter
