Chain backlash check (04_40)
To check the clearance:
•
Shut off the engine.
•
Rest the vehicle on its stand.
•
Engage neutral gear.
•
Check that the vertical oscillation at a point between the pinion and the crown
on the lower branch of the chain is approx.
25 - 30 mm (0.98 - 1.18 in).
•
Move the vehicle forward so as to check the chain vertical oscillation in other
positions too. clearance should remain constant at all wheel rotation phases.
If clearance is uniform but over 30 mm (1.18 in) or below 25 mm (0.98 in), adjustment
is necessary.
CAUTION
IF CLEARANCE IS GREATER AT SOME POSITIONS, THIS MEANS THAT SOME
CHAIN LINKS ARE FLATTENED OR JAMMED.
TO AVOID RISK OF SEIZURE, LUBRICATE THE CHAIN ON A REGULAR BASIS.
