IMPORTANT Check the wear of all the nylon pinions and replace any worn or damaged ones.
To reassemble, perform the steps described above in reverse order, taking care of:
– lubricate the chain with general purpose grease
before the assembly;
– with the steering wheel perfectly aligned, mount
the chain (3) with the central yellow link aligned
with the pinion (13) of the steering column;
– mount the adjuster of the right branch of the
chain in the seat on the left side of the machine
and vice versa;

– refit the short spring (15) on the left branch ad-
juster and adjust the relative nut (2) so as to
obtain a protrusion of the threaded section of
16 mm.
– tighten the nuts (9) and (11) with a torque
wrench set to 35-50 Nm.
IMPORTANT Tighten the nuts (1) and (2) alternately and equally from the right side and the
left side, until reaching the values indicated above.
IMPORTANT These values refer to the nominal values in the case of a new chain; however,
with wear, it's normal for the chain to stretch, requiring subsequent adjustments to obtain the
right tension. In any case, do not exceed the tightening of the nuts to prevent the spring from be-
ing compressed "like a pack", thus nullifying its damping function, resulting in hardening of the
steering and premature wear of the chain and pinions.
After the assembly, carry out a test drive of the machine and check that the machine proceeds in
a straight line, with the steering wheel perfectly centred.
