18 POWER STEERING VI. Dismantling the steering unit A) Removing and dismantling the housing cover 1. Clamp the steering unit in the assembly vice 3, or between the soft jaws of a commercially available vice. 2. Remove the hexagonal bolts (46) and also remove the housing cover (40) by turning the adjustment screw (31) in a clockwise direction (Figure 4.) Further dismantling in ZF factory only or ZF dealers . B) Removing sector shaft Withdraw the sector shaft (30) in the center position of the gearing (tooth), upwards out of the housing (Figure 5). Further dismantling in ZF factory or ZF authorized dealers only . C) Removing the piston 1. Remove the protective cap (70) from the worm end. Screw out the securing bolts (132) (Fig. 6). A burr (ridge) may have formed on the side of the piston gearing depending on the service duty of the steering unit, and this will damage the piston running surface when the piston is removed from the housing. This can be avoided if the unit is dismantled horizontally overhead (gearing (tooth) uppermost). ( Fig.7) shows dismantling in favorable position. Fig. 4 Fig. 5 Fig. 6
