In vehicles with adjustable ground clearance and/or automatic differential lock, a tandem power steering pump is used. The hydraulic fluid reservoir is located above the pump. When working on a hydraulic device, it is necessary to carefully maintain cleanliness: the slightest contamination in the oil can lead to malfunctions.
Removal
1. If equipped, remove the air intake hose at the air cleaner above the power steering pump.
2. Open the power steering reservoir cap. Remove hydraulic oil from the reservoir using a suitable syringe.
3. Unscrew the elastic high-pressure hose (29) and the return branch (28) and plug the connection points with clean plugs. In the pump, also plug the high-pressure hose (27).
4. Clamp the return hose (26) with a suitable clamp, such as a C-clamp, and unscrew it. Plug the connection with a plug.
5. Loosen the bolts (48) on the belt pulley, but do not unscrew them.
6. Remove the V-ribbed belt.
7. Unscrew the bolts and remove the pulley.
8. Unscrew the bolts (46), holding the lower bolt from below.
9. Unscrew the bolts (46) and remove the pump.
Installation
1. Screw the pump to the brackets.
2. Tighten the belt pulley fastening by hand.
3. Install the ribbed V-belt.
4. Tighten the 3 V-belt pulley bolts to 30 Nm.
5. Remove the plugs and tighten the hydraulic lines to a torque of approximately 30 Nm.
6. Fill the reservoir with hydraulic oil to a level of approximately 10 mm from the top edge. Start the engine for 1 second, then stop it. Add oil to the reservoir, the pump should not suck in air. Set the oil level correctly.
7. Adjusting the ground clearance: car Raise the rear so that the wheels are not loaded. Start the engine, let it run for a while, then stop it. With the engine off, set the oil level correctly. Then lower the car and load the trunk with a load of about 120 kg. Start the engine, set the engine speed to medium, leave the engine running for 20 seconds. Set the oil level.
8. Install the air intake hose of the air filter. After a test drive, inspect the tightness of the connection on the pump, if necessary, tighten the connectors a little.
