21 POWER STEERING B) Fitting the piston 1. Fit seals (95) in the longitudinal grooves of the piston and then fit the seals (94).(fig.9) 2. The pair of seals (97 and 98) are also fitted with the inner seal (97) first and then the outer seal (98). Place the round seal ring (102) in the recess of the piston and then fit the piston ring (103). Special care must be taken when passing the seal over the piston to ensure that no damage is caused by the edges of the piston. The small round seal rings (121) must be adhered to the recess of the of the cover (128) by means of grease. Lubricate the cylinder path well with oil. Slide in the preassembled piston up to the shoulder with the Tool –2. In order that the seal parts are not damaged the piston should be fitted in its final position, i.e. gearing (tooth) parallel to the housing sector Shaft bore. (Fig. No 9) C) Fitting The End Cover 1 Screw in and tighten the hexagon bolts (132) with the washers (131). Slide the entry bush over the serrated gearing of the steering spindle, press the shaft seal ring (129) with the sleeve so deep that the circlip (130) can just be fitted in its groove (sealing lip pointing towards the inside of the housing. Fill the space between the sealing lip and the dust lip with hot bearing grease) fit the circlip (130) (Fig.No.10) Refer to the technical data for tightening torques. D) Pre-assembly of the Cover . 1. Fit the round seal ring (52) and the seal ring (51) in the radial groove. Special care must be taken to ensure that chamfered area of the polyamide ring lies in the same chamfered surface of the groove. E) Fitting the Sector Shaft. 1. Bring the piston to the center position by turning the Input Shaft. This center point is found by first determining the total number of turns of the worm then turning back the piston from one stop by half the total number of turns. 1.2 Insert the segment shaft into the housing, taking care not to damage the sealing parts.
