Drive Chain Adjustment - APRILIA TUAREG 660 Service Station Manual

TUAREG 660
Adjusting
To check the clearance:
•
Shut off the engine.
•
Rest the vehicle on the side stand.
•
Select neutral.
•
Check that the vertical deflection of the
bottom section of the chain, measured
at a distance of 320 mm (12.59 in) from
the centre of the rear wheel axle (along
imaginary line between centres of front
and rear sprockets), is approximately
48 mm (1.88 in).
•
Move the vehicle forwards to check the vertical deflection of the chain in other positions; the
chain deflection must be constant throughout the entire rotation of the wheel.
if the clearance is uniform, but greater or less than 48 mm (1.88 in), carry out the adjustment.
CAUTION
IF THE CLEARANCE IS GREATER IN SOME POSITIONS IT MEANS THAT SOME ELEMENTS OF
THE CHAIN ARE CRUSHED OR HAVE SEIZED UP. IN THIS CASE THE CHAIN SHOULD BE RE-
PLACED.
LUBRICATE THE CHAIN REGULARLY TO PREVENT THE RISK OF SEIZURE.
For the adjustment of the chain tension:
•
Place the vehicle on its rear service
stand.
•
After completely loosening the nut (1),
operating from both sides, loosen the
two locknuts (2).
