DRIVE LEVER ADJUSTMENT
there is a free play of 0.5 mm between the shoe (10)
and the release rod (11).
C) Adjusting the clutch device
When in motion, the lever is held in the selected
position by a clutch device which is made up of a
sliding sector (12) between two friction discs (13),
pressed together by a spring (14).
The spring tension (14) is adjusted at the nut (15)
until a length of 18 mm is obtained with the pedal
released.
Check that the friction discs (13) are in good condi-
tion and with no traces of oil. Otherwise replace
them [see 6.11].
D) Adjusting the lever return cable
u Lift the wheels cover [see 2.5].
With the control lever in the "neutral" position and
the pedal released.
Check the length of the spring (16) and regulate the
adjuster (17) until a length of 74 - 76 mm is obtained
measured from the outside of the eye-rings.
When this adjustment has been made, with the
parking brake engaged, there should be free play of
0.5 ÷ 1 mm between the lever (18) and the limit stop
(19).
u Close up the wheels cover [see 2.5].
E) Adjusting the limit stop position of the levers
If the stop hook has been dismantled or replaced,
the position of the terminal (20) will need to be
adjusted compared to the levers (21) and (22).
This must be a position which prevents the terminal
(20) from interfering with the swinging movement of
the lever (21) and blocking the lever (22) at the
same time.
u Lift the wheels cover [see 2.5].
Put the control lever in "neutral" and engage the
parking brake.
