Removing and installing input shaft Special tools and workshop equipment required

t  Puller -T40050- Removing   Note t  Observe the general repair instructions → Chapter. t  Rules for cleanliness when working on the automatic gearbox → Chapter. l  Gearbox removed and mounted on assembly stand in vertical position → Anchor. –  Drain ATF → Chapter. To do so, swivel gearbox into installation position (horizontal).   Note Gearbox must not be turned such that flange points downwards.

–  Remove bolts -arrows-. –  Using a plastic hammer, carefully knock cover for input shaft to separate it from gasket.

–  Apply the puller -T40050- to the input shaft. –  Check that puller -T40050- is positioned securely on input shaft. l  Retaining ring must be pushed all the way down. –  Pull input shaft together with cover and forward clutch out of gearbox housing -arrow- using puller -T40050-.

Caution t  Do not put down input shaft on the protruding oil pipe -arrow-, as oil pipe would then become damaged. t  A damaged oil pipe will cause drive-away problems or complete gearbox failure.

–  Remove the reverse gear clutch -A- → Chapter. Installing Installation is carried out in reverse sequence; note the following: –  Assess wear on gearbox components → Chapter. –  Clean sealing surfaces on gearbox housing and input shaft cover. –  Set and install the reverse gear clutch -A- → Chapter.

–  Check whether the dowel sleeves -arrows- for centring the input shaft cover at the gearbox housing have been fitted and are firmly in position.

–  Renew axial sealing element -arrow-.   Note A sectional view of the axial sealing element is shown in order to illustrate the installation position. l  Installation position of axial sealing element: sealing lips face upwards towards input shaft cover. –  Place new paper gasket in position.

–  Align plates of reverse gear clutch using a straight-edge or similar. l  The teeth must be set exactly in line.

–  Check position of oil pipe -arrow- : l  With oil pipe fully inserted, distance -a- from end of oil pipe to input shaft should be 11.5 mm. If the distance is less, the oil pipe may be damaged (the end could have broken off if the oil pipe was pushed in too far). If the distance is larger, the oil pipe is not pushed in far enough.   Caution t  Do not put down input shaft on the protruding oil pipe -arrow-, as oil pipe would then become damaged. t  A damaged oil pipe will cause drive-away problems or complete gearbox failure. –  Insert complete input shaft assembly in gearbox housing.

–  When doing this, rotate input shaft slightly in both directions -arrow- until all clutch plates have engaged. Also lift input shaft slightly at the same time. –  Just before the input shaft is fully in position, rotate it anti-clockwise over the last few millimetres so that it engages in the teeth of the helical intermediate gearing.

–  Tighten new bolts -arrows- diagonally in stages. –  Fill up with ATF → Chapter. –  After installing gearbox, check and correct ATF level → multitronic 01J, front-wheel drive; Rep. Gr.37, → multitronic 0AN, front-wheel drive; Rep. Gr.37. Tightening torque
