In case of repairs, the tine arms can be removed and replaced individually.
• Unscrew the screws (1) of the tine arm
• Loosen the bolts (2) on the nearby tine arms
• Remove the tine arm (3) and replace the faulty components
Note
The tine arms (3) are glued together with the control arm shafts (4). To be able to loosen the
components from each other, the connecting point must be heated up (to about 300 degrees).
• When a new tine arm (3) /control arm shaft (4) is installed, these two parts must be glued
to each other before installation with high-strength adhesive.
• Apply glue (high-strength) (Part No. 939 042 0) on the front of the control arm shaft (4).
• Mount the tine arm (3) and secure with clamping sleeves (5).
• While installing the tine arm, make certain that the cam follower roller is inserted into the
running track of the cam track.
Note
The cam follower roller is securely inserted into the running track when barely any play can be
observed in the motion of the tine arm.
• Tighten all bolts to the required torque (105 Nm).
Caution!
Turn the rotor once around 360 degrees manually. The rotor must move easily. If it does not,
the tine arms are not installed correctly. The error must be eliminated so that the rotor can turn
easily.
