1 - Bolt (14÷18 Nm); 2 - Suction tube; 3 - Pulley; 4 - Nut (54÷68 Nm); 5 - Sealing ring; 6 - Bolt (13.3÷18.0 Nm); 7 - Bolt (31÷42 Nm); 8 - Back cover; 9 - Sealing gasket; 10 - Stator ring; 11 - Finger; 12 - Rotor; 13 - Gate plates; 14 - Front plate; 15 - Ring; 16 - Sealing ring; 17 - Spring; 18 - Front cover; 19 - Seal; 20 - Drive shaft; 21 - Retaining ring; 22 - Spring; 23 - Valve; 24 - Sealing washer; 25 - Nipple connector; 26 - Bolt (59÷75 Nm); 27 - Hollow bolt of the nipple connection (49÷69 Nm); 28 - Bolt (31÷42 Nm); 29 - Hollow bolt of the nipple connector (69÷78 Nm); 30 - Bolt (59÷75 Nm); 31 - Bolt (31÷42 Nm)
Removal
1. The design of the steering pump is shown in the illustration.
2. Disconnect the negative cable from the battery.
Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
3. Loosen the tensioner and remove the drive belt from the pulley.
4. Using a large syringe, suck out as much hydraulic fluid as possible from the steering pump reservoir. Place a drain pan under the vehicle to catch any spilled fluid.
5. Loosen the nuts securing the right front wheel, jack up the car and place it on supports. Remove the wheel.
6. Unscrew the hollow bolt of the union connection and separate the pressure line from the pump. Remove the sealing washers installed on both sides of the union connector (washers must be replaced without fail). Wrap the nipple connector with plastic film to minimize hydraulic fluid loss.
7. Loosen the clamp and disconnect the return hydraulic hose from the steering pump.
8. Release the right steering tie rod end from the steering knuckle arm (see section Removal and installation tie rod ends). Rotate the rod back, freeing up sufficient working space.
9. Remove the mounting bolts and the steering pump assembly.

Installation
1. Installation is carried out in the reverse order. Make sure that all fasteners (including hollow nipple bolt) was tightened to the required torque. Do not forget to replace the sealing washers of the pressure line nipple connector. Adjust the drive belt tension (see Chapter Settings and ongoing maintenance).
2. Connect the steering rod to the steering knuckle arm (see section Removal and installation tie rod ends).
3. Install the wheel, lower the vehicle to the ground and tighten the wheel nuts to the required torque (see Chapter Settings and ongoing maintenance).
4. Add the required amount of hydraulic fluid of the required grade to the steering pump reservoir (see Chapter Settings and ongoing maintenance) and "pump up" the steering system (see section Bleeding air from the hydraulic circuit of the power steering system).
