Oil circuit
The oil pump
1
pumps the engine oil past the by-pass valve
2
through the
oil filter
3
. After the oil filter, an oil line branches off to a jet
4
which
sprays engine oil onto the piston pin bearing and piston head. The second
oil line takes the main flow of oil into the front pipe of the frame
5
, where
the engine oil is cooled down. Afterwards the engine oil runs through the
fine screen filter
6
, which filters out even the finest impurities. The cleaned
engine oil is pumped through the oil line and the clutch cover into the
crankshaft to the conrod bearing
7
and drips into the crankcase. An
additional oil pump
8
sucks the engine oil out of the crankcase and pumps
it through the oil line
9
to the gear wheels of the 4th and 5th gear. Via the
gear wheels, the engine oil reaches the oil sump. The timing chain
bk
runs
through the oil sump and transports the engine oil upwards to the cylinder
head. Through the bore hole
bl
the oil reaches the camshaft
bm
and the
valves.
Oil change and bleeding of the oil system *
Note: For improved cooling of the engine oil, the front tube of the frame
was integrated into the oil circuit.Thus, when you change the oil, you also
have to drain the engine oil from the front tube and bleed the oil system. If
the oil system is not bled at all or bled insufficiently, the bearings of the
engine will not get enough lubrication, which in turn may result in engine
failure.
Therefore, we recommend that you have the engine oil changed by your
authorized KTM mechanic. During the guaranty period, the oil change must
be performed by an authorized KTM mechanic. Otherwise, the guarantee
will become void.
The engine oil change is to be carried out when the engine is still warm.
WARNING
A
N ENGINE HAVING BEEN RUN WARM
,
AND THE ENGINE OIL IN IT IS VERY HOT
-
DO NOT
BURN YOURSELF
.
Place the motorcycle on a horizontal surface. Remove the two plugs bn and
bo , and drain oil into a container. Models with integrated font pipe: Remove
cover, unscrew plug bp at the lower end of the front pipe and drain oil.
!
CAUTION
!
P
LUG
A
MUST NOT BE REMOVED
,
THIS IS PART OF THE BY
-
PASS VALVE
.
Clean all 3 plugs thoroughly with a fireproof solvent and compressed air, in
order to remove the metal abrasion. After all the oil has drained through,
clean sealing areas and install plugs with gaskets. Tighten plug
bn with
30 Nm (23 ft.lb) and plugs bo
and
bp with 20 Nm (15 lb.ft).
Remove oil dipstick on the clutch cover, fill with 1,3 litre engine oil and
attach plug again.
!
CAUTION
!
If the engine oil has been drained from the front pipe of the frame, you
must bleed the oil system !
To facilitate bleeding of the oil system, we have added a hose connection
piece and a plastic hose to the set of tools. Take an empty oil can (1 liter)
and drill a 7 mm-diameter hole into the lid. Screw the hose connection
piece into the lid from the outside, and secure it from the inside with the
M8 hexagon nut.
Slip the plastic hose onto the hose connection piece, and you will have your
filling tool.
Fill 0.6 liters of engine oil into the can and remove the plug
bq
next to the
steering head. Introduce the plastic hose into the vent hole
B
, and fill 0.6
liters of engine oil into the frame’s front tube. Remove plastic hose, start
engine, and let it idle (approx. 20 seconds) until oil escapes at the hole
B
.
As soon as oil starts to escape, turn off the engine, and mount the plug
together with the gasket.
