Pre-load comparator (1) by approximately 4 mm and reset
it by suitable lever (4), lift upper swinging arm (3) as much
as possible and detect the displacement of comparator (1)
hand corresponding to the clearance of articulated head (2).
If detected value is between 1.5 and 2.0 mm, the articulated
head (2) needs to be replaced, as described in relating
chapter.
Position comparator (1) tracer point with magnetic base
99395684 on the top of the articulated head of lower
swinging arm (2).
By suitable lever, lower swinging arm (2) and reset
comparator (1).
By suitable pliers (2) applied on articulated head (3) and on
lower swinging arm (1), apply strong pressure on head and
arm and write down comparator (4) hand displacement
corresponding to articulated head clearance.
If detected value is between 1.5 and 2.0 mm, the swinging arm
needs to be replaced, as described in relating chapter.
Remount dismounted parts in order to make checks.
Check the clearance of lower swinging arm
articulated head
See Figure 26: the nut for screw (3) to secure tie rod
(2) to lower swinging arm (1) and see Figure 25: the
nut (4) for the screw to secure lower swinging arm
(2) to cross member (3): they must be tightened at
prescribed torque with the vehicle lowered and
vehicle empty weight weighing down on suspension.
