MECHANICAL INSTALLATION
CAUTION
If there is too much distance between the knuckle eye and the shaft bearing, this generates
bending moments in the shaft, causing it to deform.
This deformation puts strain on points of the edges of the inner bearing shell, which can
cause the knuckle eye or shaft to suffer damage or break.
Select the play as recommended in the mounting instructions.
To determine the play between the knuckle eye and the shaft bearing, please use the
details from the following table:
