Two cam disc groups are assigned to each contact, consisting of adjustable cams (6) and cam discs (7). Each
cam disc pair can be adjusted infinitely and used in a defined way from both sides. The effective cam angle (10)
and the usable angle of the cam disc (11) are shown in the figure. x* and y* depict the views.
1. Loosen the nut (3) until the front toothing disengages for one adjustable cam. The adjustment can then take
place without the other cam disc groups also being adjusted.
Turn the selected cam disc (7) by hand to the required, approximate switching positions and to the required
cam angle.
2. Tighten the nut (3) to a tightening torque of 2,5 Nm.
3. Using a screw driver, max. width of 4 mm, turn the screw on the adjustment worm (8) until the switching point
has been adjusted as desired and the required cam angle has been achieved. An extremely fine adjustment
is possible from both sides, without having to loosen the nut (3).
4. All adjustments must be looked at in an inspection round and checked for functionality.
5. Mount the cover of the GTES, see section 6.7.
