In extreme situations, the steering pump may have been worn to such an extent that metal pump parts have entered the steering box. Check the EMAS system for correct operation. 1. Clean the pipe connections. 2. Place a receptacle underneath the steering pump. 3. Remove the pipes from the steering pump and plug the pipe and pump openings. The steering oil filter is fitted in the return pipe, which means that should any dirt enter, it will immediately also enter the steering gear. 4. Remove the attachment bolts (2) and take the steering pump (1) out of the bearing housing (3). Installing the LUK VT72A steering pump Thoroughly remove any preserving grease, especially from the prop shaft. 2. If necessary, connect the pipe couplings to the steering pump to be fitted.

Check the drive key for damage. 4. Fit the key into the prop shaft. 5. Fit the pump (1) to the bearing housing (3). 6. Insert the attachment bolts (2). Tighten the attachment bolts evenly to the specified tightening torque, see 'Technical data'. 7. Fit the pipes. 8. Fill and bleed the EMAS system. 9. Check the operation of the EMAS system and for leaks of the pipe connections. 1 2 3 S7 00 858 } |
