Lubrication and cleaning
NOTE:
Lubricate the chain frequently, es
-
pecially if you find any parts that are dry or
rusty. Smashed or jammed links must be
lubricated and returned to proper work con-
ditions.
If this is not possible, contact a VENT Deal-
er to have them replaced.
Never wash the chain with water jets,
steam jets, high-pressure water, and never
use highly flammable solvents.
- Clean the chain with special detergents
for OR-ring chains, then dry it with a
clean cloth.
- Lubricate the chain with a suitable spray
lubricant for OR-ring chains.
WARNING
Never use grease to lubricate the chain.
Grease causes dust and mud build-
ups that work like abrasives, resulting
in quick wear of the chain, pinion and
crown.
Play inspection.
- Turn off the engine.
- Park the vehicle on its kickstand.
- Place the gear lever in its neutral posi-
tion.
- Make sure the vertical oscillation (B), in
an intermediate point between pinion and
crown in the lower branch of the chain, is
of about 40 mm.
- Move the vehicle forward in order to
check the vertical oscillation of the chain
in other positions as well; the play must
remain constant in all the phases of
wheel rotation.
- If the play is uniform, but above or below
40 mm, adjust it.
Chain tension regulation
- Loosen the wheel nut (1), locking the
wheel pin (2) from the other side.
NOTE: For the centring of the back wheel,
there are reference notches (C) printed on
both tips of the swingarm arms.
- Loosen the right (3) and left (4) locknuts.
- Work on the right (5) and left (6) chain
adjusters to regulate chain play. Make
sure the same references are used on
both sides of the vehicle.
WARNING
On both sides of the vehicle, make sure
that the seat (D) present on the bracket
is properly coupled with the pin
(E) present at the head of the chain ad-
juster.
- Tighten the right (3) and left (4) locknuts.
- Tighten the wheel nut (1), locking the
wheel pin (2) from the other side.
Wheel nut (1) torque: 90 Nm (9 kg/m).
- Check chain play.
