INSTRUCTIONS FOR USE
• Remove the elastic small block of the front support (timing
system side) of the power unit and the hard support of the unit
on the timing system side.
• Remove the protection cover of the front timing system control
positioned in the lower part.
• Assemble the timing system plate of the driving shaft (ref. D)
(fig. 2)
• Loosen the nut of the movable screw coupling and remove the
belt of the timing system control (fig. 3-1).
• Loosen the fixing screw of the driven pulley (fig. 3-2).
ASSEMBLY OF THE DISTRIBUTION CHAIN
• Now assemble the belt of the timing system control, trigging it
on the gear of the driving shaft, on the pulley of the water
pump, on the driven pulley and on the movable screw coupling
(fig. 4).
N.B. this process has to be carried out when the driven
pulley is loosened.
• Stretch at maximum the timing belt, rotating the movable
screw coupling (ref. A) (fig. 5) anticlockwise and fix it with the
nut only when the reference is in the position indicated by the
figure.
• Tighten the fixing screw on the driven pulley.
• Remove the tools for the timing of the camshafts and the
driving shaft assembled.
• Make the driving shaft do two revolutions, then loosen the
stop nut of the movable screw coupling and turn it till coinci
ding the mark with the rear fork.
• Tighten the stop nut of the movable screw coupling of the
timing control belt.
