Pull off spring washer (41), tension washer (40), rubber spring (36) and bar guide (38) (including the support plate (47)) from the drawbar (1). Caution: The support plate (47) is not included in all coupling types. The assembly sequence for coupling types without support plate is the same, except the support plate does not apply. Remove support plate (47) from the bar guide (38). Fit bar guide (38) contrary to the driving direction to the inner face of the rear cross member. Fit support plate (47) in driving direction to the outer face of the cross member and onto the bar guide shank. Tighten the bar guide (38) (including support plate) together with the cross member using 4 fastening bolts quality 8.8 and 4 hexagonal nuts quality 8. On the cross member washers DIN 125, hardness 200-250 HV have to be added. Fit coupling head assembly including the front rubber Bolt length: bolt shank + washer thickness + nut length + at least 2 threads projection spring (36) and thrust washer (37) to the bar guide (38). If required, regrease drawbar (1). Fit the rear rubber spring (36), tension washer (40) and spring washer (41). Screw on and tighten the castellated nut (42) and secure using a cotter pin. To reach the next hole position for the cotter pin even higher tightening torques may be required. Min. Tightening Torques Fit protective plastic cap (44). Straighten the coupling. For a retro-fit please refer to the relevant statutory regulations. Fitting of this coupling may only be effected on those vehicles which due to their construction prevent the trailer from running up in case the drawbar eye misses the coupling mouth, and the rear end design of which does not allow a horizontal articulation of the trailer tow bar exceeding 80. On this assumption the trailer coupling types are approved for: a) motor vehicles according to DIN 74051, footnote 3, e.g. motor vehicles type UNIMOG from Daimler Benz AG, b) towing vehicles according to StVZO 43, paragraph 4, fig. 2, c) multiple axle trailers. Operation: Wrench Size M 30 250 Nm = 46 mm M 36 x 3 350 Nm = 55 mm M 45 x 3 500 Nm = 70 mm Pull out and hold the button-type safety device (4), move handle (15) upwards until the coupling bolt locks into place. Insert the towing eye. While the coupling bolt (23) is being lifted the catch is released and the coupling bolt slides into position. Simultaneously the button-type safety device (4) is released that is to say the safety bar locates over the coupling bolt and thus locking it automatically. The towing eye is now engaged. Check that after each coupling process the button-type safety device (4) is fully engaged so that the securing knob is in its internal engaged position. If this is not the case the trailer coupling is unsecured and the whole coupling procedure must be repeated. To uncouple and open the trailer coupling proceed as described. The towing eye is extended by moving forward the towing vehicle. Due to the extension of the towing eye the coupling mechanism is again released and thus the coupling repeatedly closed and secured. Maintenance: The coupling bolt and towing eye will be subject to less wear and tear if they are always kept clean and well lubricated. Should the wear limit of 36.5 mm of the coupling bolt in the bulged area (outside diameter) be reached the coupling bolt has to be replaced by a new one. Fig. 1 The handle can be fitted on the right or left-hand side if only the return spring is chosen correspondingly (please refer to fig. 1 and fig. 2). e 1 x e 2 d 2 Thread Torque Moment Wrench Type (mm) (mm) (Standard Thread) Size (mm) 83 x 56 ø 10,5 M 10 49 Nm 17(16) 604 120 x 55 ø15 M 14 135 Nm 22 605 140 x 80 ø17 M 16 210 Nm 24 6041 160 x 100 ø21 M 20 410 Nm 30 6051 Fig. 2
