ADJUSTMENT OF FREE TRAVEL OF
CLUTCH PEDAL
Correct play between pedal piston rod
and main cylinder piston is not adjusted -
play is adjusted by the producer.
Mutual position between the piston rod
and piston rod eye (1) is adjusted so that
the piston rod might be maximally pulled
out from the cylinder and simultaneously
the play between the pedal and the
upper stop screw (2) might be 0,1-0,2
mm. Subsequently the piston rod is fixed
with the nut (3) to piston rod eye. Check
eventual deformation of dust cap after
adjustment, in case of deformation
correct it by hand.
BLEEDING OF HYDRAULIC CLUTCH
CIRCUIT
Bleed the clutch hydraulic circuit in the
same way as rear brake system bleed-
ing. The vent screw of clutch hydraulic
circuit is located at the clutch control
cylinder (1).
Add only fresh brake fluid into the
brake fluid tank, which is
common for both brake and
clutch circuits.
Brake fluid must be replaced in the entire
brake circuit including the clutch
hydraulic circuit after each two years of
operation.
