AL-KO overrun coupling 90 S/3, V-head, 700-1000 kg, mounting top, 100/147-170/125 mm, incl. spring cylinder
AL-KO 90 S/3 overrun coupling with V-head for top mounting on A-frame drawbars of braked trailers. When the trailer runs up on the towing vehicle, it transmits the braking force to the wheel brakes; a spring cylinder is included.
Before replacement, measure the connection dimensions of the V-connection on the existing drawbar and compare them with the coupling. After fitting, adjust the brake system starting from the wheel brakes and check the parking brake.
