2012 YAMAHA RHINO 700 engine

8-37
NOTICE

In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives with oil.
Do not use oils with a diesel specification
of “CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or high-
er.


Make sure that no foreign material enters
the crankcase.
13. Start the engine, and then let it idle for sever-
al 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 10 minutes,
and then check the oil level and correct it if
necessary.
15. Reinstall the console.

Coolant
The coolant level should be checked before each
ride.
Checking the coolant level
1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reser-
voir when the engine is cold as the coolant
level varies with engine temperature. TIPThe coolant should be between the minimum and
maximum level marks.3. If the coolant is at or below the minimum level
mark, remove the coolant reservoir cap, add
coolant to the maximum level mark, reinstall
the reservoir cap.
Coolant reservoir capacity
(up to the maximum level mark):
0.32 L (0.34 US qt, 0.28 Imp.qt)

Inspection
The spark plug is an important engine component
and is easy to inspect. The condition of the spark
plug can indicate the condition of the engine.
The ideal color of the porcelain insulator around
the center electrode is a medium-to-light tan for a
vehicle that is being ridden normally.
You should periodically remove and inspect the
spark plug because heat and deposits will cause
the spark plug to slowly break down and erode. If
electrode erosion becomes excessive, or if carbon
and other deposits are excessive, you should re-
place the spark plug with the specified plug.
Measure the spark plug gap with a wire thickness
gauge and, if necessary, adjust the gap to specifi-
cation.Specified spark plug:
CPR7EA-9 (NGK)
Spark plug gap:
0.8–0.9 mm (0.031–0.035 in)

The air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated
more often if the vehicle is operated in extremely
dusty areas. Each time air filter element mainte-
nance is performed, check the air inlet to the air fil-
ter case for obstructions. Check the air filter
element rubber joint to the throttle body and mani-
fold fittings for an airtight seal. Tighten all fittings
securely to avoid the possibility of unfiltered air en-
tering the engine.NOTICENever operate the engine with the air filter ele-
ment removed. This will allow unfiltered air to
enter, causing rapid engine wear and possible
engine damage. Additionally, operation with-
out the air filter element will affect the fuel in-
jection system with subsequent poor
performance and possible engine overheating.

V-belt case drain plug
The V-belt case drain plug is located under the
driver seat. (See page 4-37 for seat removal and
installation procedures.)
After riding in water deep enough to allow water to
enter the V-belt case, remove the drain plug to
drain any water from the case.
If water drains from the V-belt case after removing
the drain plug, have a Yamaha dealer inspect the
vehicle, as the water may affect other engine
parts.

Cleaning the spark arrester
WARNING
Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the engine
is stopped and the exhaust system is cool be-
fore cleaning the spark arrester. Do not start
the engine while cleaning the exhaust system.1. Remove the tailpipe bolts.
2. Remove the tailpipe by pulling it out of the
muffler, and then remove the gasket.
3. Tap the tailpipe lightly, and then use a wire
brush to remove any carbon deposits from
the spark arrester portion of the tailpipe and
inside of the tailpipe housing.
4. Install the gasket, and then insert the tailpipe
into the muffler and align the bolt holes.
5. Install the bolts and tighten them to the spec-
ified torque.

Valve clearance
The correct valve clearance changes with use, re-
sulting in improper fuel/air supply or engine noise.
To prevent this, the valve clearance must be ad-
justed regularly. This adjustment however, should
be left to a professional Yamaha service techni-
cian.Tightening torque:
Tailpipe bolt:
10 Nm (1.0 m·kgf, 7.2 ft·lbf)
