Part 2
29. Disconnect the ATF lines on the cooler. To do this, loosen the fastening screw and pull off the line. Seal open lines with a plug.Heat Protection Shield On Steering Gear Connection:
30. Remove the heat protection shield on the steering gear connection. To do this, loosen the 2 fastening screws.
Note: In the case of vehicles with Servotronic, an electric plug must also be removed from the steering gear.
Clamping Screw On Steering Column:
31. Loosen the clamping screw from the steering column on the steering gear and remove it. The screw must not be re-used. Force the steering column up and off the steering gear.
32. Disconnect the electric plug on the steering gear (Servotronic only).
Heat Exchanger Coolant Lines In The Left Wheel Housing:
33. Disconnect the heat exchanger coolant lines in the left wheel housing below. Approximately 2 litres of coolant will flow out when you do this.
34. Remove the complete exhaust system from the connection point on the catalytic converter to the tailpipes --> '260119 Removing and installing exhaust system - chapter on "Removing"'.
35. Remove rear cardan shaft --> '393519 Removing and installing rear cardan shaft'.
Electric Connections On The Transmission:
Connections On Transfer Box:
36. Disconnect electrical connections -1, 2 and 3- on the transmission and unclip the wiring harness.
Fastening Screws For Heat Protection Shield:
37. Remove the heat shield on the left transmission side. To do so, loosen the 3 fastening screws and take out the heat protection shield.
Note: Do not loosen nut.
38. Detach the selector lever cable on the transmission. To do this, press the ball socket away from the transmission. Then pull out top sheetmetal clip -A- and remove the cable in an upward direction.
Note: If the transmission is to be separated from the engine after removal, the two lower fastening screws on the transmission housing and front cardan shaft should be removed at this point, since access to the lifting platform will be impaired.
WARNING: Servo oil is aggressive!
^ Possible danger of injury or damage (swollen hoses, skin irritation, danger of slipping, etc.)
--> Before lines are opened, place a cloth underneath them!
--> Components that come into contact with servo oil must be cleaned IMMEDIATELY with water!
--> Take suitable protective measures (e.g. gloves, safety goggles, oil binding material)
Lower Line On Servo Oil Cooler:
39. Disconnect the lower line on the servo oil cooler.
Note:
Locking Spring On Turbocharger Adapter And Hose Clamp Of Turbocharger Pressure Pipe:
^ On the Cayenne Turbo (M48/50), the hose connections on the turbochargers must also be loosened. To do this, pull out locking spring -1- on the turbocharger adapter. Then loosen hose clamp -2- of the pressure pipe on the turbocharger.
Locking Clip And Line Of Ambient Air Valve:
^ Disconnect the connection on the charge air cooler. To do this, remove locking clip -1- and pull off the line. Line -2- of the ambient air valve must also be disconnected on the right-hand side of the vehicle. To do this, remove the spring band clamp and pull off the line.
Note:
^ It is easier to remove the air-conditioning compressor from its installation position when the engine has already been lowered a little.
^ The air-conditioning compressor lines must not be kinked or twisted.
^ The lines of the air-conditioning compressor remain mounted, so the refrigerant does not need to be evacuated.
Fastening Screws And Electric Connector Of Air-Conditioning Compressor:
40. Loosen the 3 fastening screws and disconnect the electric plug from the air-conditioning compressor. Set the air-conditioning compressor aside.
Air-Conditioning Compressor:
41. The air-conditioning compressor must be secured with a piece of wire.
Note: For installation, it is a good idea to mark the installation position of the front axle carrier diagonally at least two places on the body. To do this, place the marks vertically with respect to the floor of the body using a felt-tip pen (e.g. mark along the front-axle carrier mount with the pen).
Mark Installation Position Of The Front-Axle Carrier:
42. Mark the installation position of the front axle carrier diagonally at least two places on the body.
Note: Because of the high loosening torque, the 6 fastening screws on the front-axle carrier can now be loosened. Loosen the screws by a maximum of one turn.
Elevating Platform:
43. Place the elevating platform under the engine and raise it. When you do this, ensure that the positioning guides of the elevating platform are inserted into the body.
Securing The Spring Struts:
44. Secure the spring struts. To do this, turn the rubber discs upwards until they are set under the steering knuckle. Then tighten the retaining brackets on the wheel hub and elevating platform.
Fastening Screws For Transmission Cross Member:
45. Loosen the transmission cross member. To do this, loosen the 4 fastening screws -A-.
46. Secure the engine/transmission combination. Then secure the mounting mandrels on the engine transverse bar with locking screws.
Fastening Screws For Front-Axle Carrier And Fastening Screws For Engine Transverse Bar:
47. Loosen the 4 fastening screws on the front-axle carrier and the 2 fastening screws on the engine transverse bar.
Note: When lowering the engine, make sure that cables or lines do not get mounted accidentally between engine and body. Thus a second person should make sure that the cables and lines do not get caught.
48. Lower the lifting platform slowly. When this is done, a second person should ensure that there is sufficient clearance around the engine compartment and wheel housings.
