SEAT Workshop Service and Repair Manuals

Assembling –  Place the differential on the clutch housing.

–  Sealing washers -arrows- must always be renewed.   Note The figure only shows 3 or 4 bolts with their O-ring gaskets.

Gearbox with selector lever for reverse gear -arrow-

–  Insert the input shaft -1- and secondary shaft -2- together. –  Partially screw the 4 nuts crosswise on the secondary shaft bearing cover, and tighten to corresponding torque → Item. –  Place the mobile pinion for reverse gear -3- onto the needle bearing of the clutch housing. The groove -arrow- should face away from the clutch housing. –  Ensure that reverse shaft -4- is complete → Chapter; do not yet fit reverse shaft support to reverse shaft. –  Fit the reverse shaft into clutch housing. –  Clean all locking fluid away from all threaded holes in reverse shaft support; a thread cutter may be used for this purpose. –  Place the reverse shaft support on this threaded hole.

–  Mount the gear prong of the reverse gear -1- with the support for the gear prong of the reverse gear -2-, the spring -3- and the slide -4-.

Installation position: reverse gear

–  Tighten the bolts of the gear selection mechanism of the reverse gear -A- to 25 Nm. –  Install the gear prong -B- along with the selector plates. The screwing surface of the reverse shaft support -C- is located in front of selector plates.

Gearbox with locking collar for reverse gear -arrow-

l  Clean all locking fluid away from all threaded holes in reverse shaft support; a thread cutter may be used for this purpose. l  Place the output shaft -1-, the input shaft -2- and the inverter shaft -3- on a work bench as shown in the illustration. l  The splines -arrow- of the locking collar of the points crown points to the selector gear of reverse gear.   Note Disregard item 3435

–  Insert the output shaft -1-, the input shaft -2- and the inverter shaft -3- together. Output shaft -2- contacts differential. –  In order to be able to insert the output shaft -2- into the differential gearbox, the differential gearbox may have to be rotated (have a second mechanic help). –  Tighten the nuts and the bearing support of the differential gearbox to the respective tightening torque → Item.

–  Install the gear prong -A- along with the selector plates. Reverse shaft support -B- is located in front of selector plates. l  The reverse gear with selector strip engages in the reverse gear locking collar -arrow-:

Continued for all vehicles –  Screw M 8 x 100 mm studs -A- into reverse shaft support so that shaft is aligned after gearbox housing is fitted. –  Align gear selector plates.   Note The selector segments must be positioned in the grooves on the locking collars. –  Apply sealing compound → Spare parts catalogue evenly to sealing surface of clutch housing. –  Fit gearbox housing. Insert the bolts for reverse gear shaft support -arrow- as shown: –  Insert the bolt -a-. –  Remove stud -A- (⇒ top illustration).

–  Fit bolt -c- Tightening sequence: –  Tighten bolt -a- to 30 Nm. –  Tighten the bolt -b- (⇒ bottom illustration) to 25 Nm.

–  Screw in bolts -arrow-. Tightening torque → Item

–  Install the bearing bolts -arrow- for the gearbox prongs. To do this align selector mechanism using a screwdriver so that the relevant pivot pin can be inserted. –  Apply a layer of sealing compound → Spare parts catalogue evenly, onto the cover sealing surface . –  Fit cover plate for selector shaft.

Fit the selection shaft with the cover as shown below: –  Place the gearshift lever in neutral position. –  Apply sealing compound → Spare parts catalogue evenly on to the sealing surface of the selector shaft cover. –  Move the selector shaft to neutral. –  Insert the selector shaft so that selector finger -arrow- is engaged in selector plates. –  Mount the selector shaft cover, and fasten it with two bolts. Tightening torque → Item. –  Screw in gear control cover for selector shaft. Tightening torque → Item

–  Install both flange shafts with springs, thrust washers and tapered rings → Chapter.
