Skoda Workshop Service and Repair Manuals

Replace gasket for metering mechanism Special tools and workshop equipment required t  Bracket -T30097/1 (T10108/1)- t  Triangle wrench -T10366- –  Determine the injection rate of the injection pump as follows: Test conditions l  Mechanical basic setting of the engine o.k. l  Toothed belt tension o.k. → Chapter. l  The coolant temperature must be at least 80 °C. Work procedure –  Check the readout of the injection rate in idle → Vehicle diagnostic tester. Specified value: 3.0 ... 9.0 mg/s –  Note the readout of the injection rate (measured value block 1, line 3). –  Remove the injection pump → Chapter. –  Unscrew the connection fitting for the return flow line and empty the injection pump into a catch pan by holding it with the return flow hole facing down.

–  Install bracket -T30097/1 (T10108/1)- on the injection pump flange and tighten screws -A- to 20 Nm. –  Fasten the injection pump via the bracket -T30097/1 (T10108/1)- in a vice.

–  Mark the installation position of the metering mechanism with a scribe line -arrow-. –  Remove the cable from the fuel shut-off valve -N109- incl. bracket.

–  Unscrew the 3 fixing screws -A-. –  Unscrew special screw -B- with triangle wrench -T10366-. –  Carefully swivel the metering mechanism completely to the side.   Note Pay attention to corrosion or deposits in the area of the flange.

–  Carefully lever the old gasket out of its position and replace.   Note To do so, pay attention to the correct fitting of the »peg«-arrow-.

–  Carefully place the metering mechanism on the injection pump.   WARNING Pay attention that the ball pin of the metering adjuster -1- grips properly into the recess of the metering slider -2-. –  Insert the 3 fixing screws of the metering mechanism and tighten loosely by hand.   Note Leave out the special screw. –  Position the metering mechanism on the scribe marking. –  Tighten the 3 fixing screws of the metering mechanism crosswise to 9 Nm. –  Unscrew the 3 fixing screws of the metering mechanism cover and remove the cover.   Note Pay attention to corrosion or deposits in the area of the flange.

–  Carefully lever the old gasket out of its position and replace.   Note To do so, pay attention to the correct fitting of the »peg«-arrow-. –  Position the cover on the metering mechanism, insert the 3 fixing screws and tighten to 9 Nm. –  Install special screw and tighten with triangle wrench -T10366- to 9 Nm. –  Install the connection fitting for the return flow line and tighten to 27 Nm. –  Installing the injection pump → Chapter.   Note After the installation, the fuel injection rate must be checked and if necessary set → Chapter.
