– Insert hub into cage via the two chamfers. The hub can be
installed in any position. Press balls into cage.
The ball hub has two different distances between the ball tracks:
a smaller one and a larger one.
– Fit the hub with the cage and the balls vertically in the cage
element.
When fitting, ensure that the larger distance -a- on the joint hous‐
ing coincides at all points with the smaller distance -b- on the hub
after turning it.
Chamfer on internal circumference of ball hub (splines) must face
large diameter of joint body.
– Also take note of chamfer on interior diameter of ball hub. It
must be visible after swivelling in.
– Swivel the hub into the joint body; at the same time the hub
must be swivelled out of the cage -arrows- far enough to allow
the balls to fit into the ball tracks.
– Swivel in hub with balls by applying firm pressure to cage
-arrow-.
Checking function of constant velocity joint
The constant velocity joint is correctly assembled if the ball hub
can be moved by hand backwards and forwards over its entire
range of axial movement.
