Skoda Workshop Service and Repair Manuals

Removing and installing hydraulic lines (TRW) Special tools and workshop equipment required t  Engine/gearbox jack with adapter, e.g. - V.A.G 1383 A- with -V.A.G 1359/2- t  Wooden insert 490 x 270 x 50 mm for adapter -V.A.G 1359/2- t  Fixing device -T10096- t  Ball joint extractor -3287A- t  Extraction bottle (commercially available) t  Catch pan (commercially available) t  Plastic screw plugs for line connections on the power-assisted steering gear (commercially available) t  Hydraulic oil → Chapter Notes for working on hydraulic lines t  After extraction there will be residual hydraulic oil in the engine pump aggregate as well as in the return line and pressure line (expansion hose). t  Do not use drained hydraulic oil again. t  Do not pinch off the pressure hose and the return hose with hose clamps -MP7-602 (3094)- or any other tools. Pinching off may cause damage to the hydraulic lines. t  Use new hollow screw for the connection of the pressure line to the power steering gear TRW. t  Pay attention to fitting location of the pressure line (flexible hose) → Chapter. t  To avoid damage make sure the bending radius of at least 100 mm is respected when bending or tying up the expansion hose or return hose. t  Replace O-rings as well as gasket rings on the hydraulic lines after each removal. Removing: –  Use catch pan to collect the drained off hydraulic oil.   Note Because of the different dimensions of the battery the screw cap of the hydraulic oil reservoir on certain vehicle versions is concealed by the battery tray and battery. If this is the case remove the battery and the battery tray. –  Disconnect battery → Electrical System; Rep. gr.27.   Note In order to facilitate an easier access, if necessary remove air filter → Engine; Rep. gr.24 (petrol engines) or → Engine; Rep. gr.23 (diesel engines).

–  Unscrew the screwed lid -1- for the hydraulic oil reservoir -2- of the engine pump aggregate. –  Extract the hydraulic oil with an extraction bottle via the filler neck. –  Remove wheels at the front. –  Remove the front left wheelhouse liner → Body Work; Rep. gr.66.

–  Unclip return line from the line holders -arrows-.

–  Take pressure line -1- or return line -2- out of the spacer holder -arrow-. 3 - Lines of power-assisted steering sensor -G250- (if present)

–  Open the spring strap clamp -1- with assembly pliers and carefully pull off the return line from the support of the engine pump aggregate -3-. –  Unscrew pipe screw -2- from the engine pump aggragate and pull out the pressure line. –  Close the threaded bores -2- and supports -1- on the engine pump aggregate. –  Lower the assembly carrier in the service position (depending upon the vehicle version - axle up to CW 11 2008 → Chapter or axle as of CW 12 2008 → Chapter).   Caution When lowering the assembly carrier with the power steering, make sure the pressure line (expansion hose), return hose and the line of the power-steering sensor -G250- are not exposed to traction. –  Lowering assembly carrier with power-assisted steering gear.

–  Disconnect pressure line -1- or return-flow line -2- from steering gear. 3 -  Sensor for power steering -G250- 4 -  Assembly carrier 5 -  Fixing device -T10096- –  Seal threaded holes on the steering gear (e.g. with plastic screw plugs). –  Remove pressure or return line. Installing: –  When installing the pressure line it is essential to pay attention to the fitting location → Chapter. –  Mount return line with new O-ring on the power steering gear. –  Attach a pressure line tightly with new seals to the power steering gear → Chapter. –  Screw return line with new O-ring onto the engine pump aggregate. Further installation occurs in reverse order, while paying attention to the following: –  Install the assembly carrier (depending upon the vehicle version - axle up to CW 11 2008 → Chapter or axle as of CW 12 2008 → Chapter). –  Filling with hydraulic oil and bleeding the steering system → Chapter. –  Perform a test drive. –  Check the steering wheel position during the test drive.   Caution If after the test drive and with the front wheels pointing straight ahead the steering wheel is off straight, perform a chassis alignment → Chapter. –  Perform chassis alignment → Chapter.
