6.4.3.2 Option rb/rm/rs, rc/ro/rs
Replacing the ball coupling with a towing eye in towing systems with overrun brake
The rear fastening screw 6 has also the function of a shock absorber retaining screw. Because the
shock absorber extends independently during de-installation, you must thread the fastening eye of
the shock absorber. Use a mounting pin (thin metal rod with ø 0.3–0.4 in.) to facilitate the installa‐
tion. In order to be able to remove the ball coupling or the towing eye and the spacers from the
towbar when the shock absorber's eye is threaded, the length of the mounting pin must be smaller
than the diameter of the towbar, see also illustration
22.
The following alternative tasks must be carried out to change the towing eye or the ball coupling.
