Tensioning The Drive Chain - Monster 659 Owner's Manual

Tensioning the drive chain

E
Turn the rear wheel slowly to find the position at which the
chain is at its most taut. With the motorcycle on its sidestand,
press with a finger in the centre of the bottom run of the chain
and measure the distance between the centres of chain link
pins and the aluminium swingarm. The distance should be
within 46 to 48 mm. To adjust the tension loosen the wheel
shaft nut (1), tighten the screw (2) to the same torque in the
opposite direction on both sides of the swingarm in order to
increase the tension or loosen to reduce it. In the latter case,
you will need to push the wheel forward.
Important
Have chain tension adjusted by a Ducati Dealer or
authorised Service Centre.
Important
An incorrectly tensioned chain will lead to accelerated
wear of the transmission components.
Check the positioning marks on both sides of the swingarm, to
guarantee the perfect wheel alignment. Grease the wheel shaft
nut (1) thread with SHELL Retinax HDX2 and tighten to a torque
of 145 Nm. Grease the adjusting screws (2) thread with SHELL
Alvania R3 and tighten them to a torque of 10 Nm.
Warning
Correct tightening of swinging arm screws (1) is critical
to rider and passenger safety.
