ADJUSTING BRAKES
When adjusting the brakes, connect a hydraulic pump to the
access hole of the negative brake and introduce pressure at 20-25
bar to release the brake disc.
Rotate the pinion (19) anti-clockwise until it reaches end of stroke,
i.e.: until a slight torque is obtained.
NOTE.
All existing clearances between discs are eliminated as a
result of this operation.
Rotate pinion (19) clockwise to obtain the accurate clearance.
Axles with two frictiondiscs
: 3 turns + 3 sides; clearance: 0.75
mm;
Axles with three frictindiscs
: 5 turns; clearance: 1 mm.
NOTE.
Every turn of the pinion produces a clearance of 0.2 mm.
Release pressure, fit the catch (18) and lock with screw (38) coated
with Loctite 242.
Tighten screw to a torque of 20±30 Nm.
MECHANICAL RELEASE OF NEGATIVE BRAKE
Loosen the check nuts (37) of screws (36) for manual mechanical
release; move nuts backwards by 6 mm approx.
Tighten screws (36) until they are seated on the driving plate (10).
