SEAT Workshop Service and Repair Manuals

Installing and adjusting clutch   Caution Avoid removing or lifting plate carrier. Not even a little bit! The plates could turn. Brief description

l  Gearbox must be turned vertical in assembly bracket. Only this way is it possible later to adjust axial play of the clutch without error. l  It is essential that the gearbox be securely clamped in support clamp -VW 313- or engine and gearbox support -VAS 6095- → Chapter. It must not be turned. l  Inside the clutch, the large plate carrier goes through all plates. It must not slip out of the lowest plates. l  The oil pump shaft is removed. l  Do not install corrugated retaining rings Special tools and workshop equipment required

t  Retaining pin -T10303-

–  First set -retaining pin- on seat of cover.

–  Then insert -clutch- without letting it fall in. Do not mount on clutch. Clutch is inserted with cover as it was when packaged.

–  The -retaining pin- should be held by a second mechanic in the process. -Retaining pin- remains inserted until all further work has been completed. Do not remove the pin until instructed to do so. But not yet.

–  Carefully remove clutch cover -arrow- from clutch and lay it to side.   Caution Avoid removing or lifting plate carrier. Not even a little bit! The plates could turn.

–  Select retaining ring with -2 millimetre diameter- from among the rings supplied and install it temporarily. Before this ring is removed again, 2 measurements must be made. First measurement: l  Retaining pin -T10303- remains in! –  Screw universal dial gauge -VW 387- to gearbox flange.

–  Set -tip of dial gauge- on input shaft. –  Set -dial gauge- to 0 with preload. –  Raise clutch to stop and note result of measurement. Second measurement: l  Retaining pin -T10303- remains in!

–  Set tip of dial gauge -on hub of large plate carrier-. Tip must not sit on retaining ring. –  Set -dial gauge- to 0 with preload again. –  Raise clutch to stop again and also note this result. Now it can be determined which of the remaining 9 rings will ultimately be installed: –  Use this formula:    Second measurement - first measurement + 1.85 mm = thickness of ring to be installed –  Please note down this result.

The remaining 9 retaining rings are in increments of 0.1 millimetre. –  Measure all rings and determine which ring is closest to your result. –  Remove 2 mm thick ring and install calculated ring. –  Dispose of all remaining rings and the 2 mm ring. Retaining rings are only allowed to be installed once.

–  Insert -pump shaft-.

–  Install clutch cover so that lug aligns with marking.

–  Then remove retaining pin -T10303-. –  Install cover (end cover) → Chapter. This concludes the installation and the clutch is correctly adjusted. After installing gearbox –  Conduct basic adjustment of mechatronic unit for dual clutch gearbox -J743-.

Special care

Any assembly work performed on the multiple clutch requires extra care as all the components are calibrated and matched together in production. If parts are turned relative to each other, imbalances result which reduce ease of shifting and service life.

If parts of clutch have slipped out or plate carriers have been lifted:

Then the large plate carrier and if necessary, also the small one can be threaded into all inner plates with gentle turning movements.

Especially the clutch cover should always be installed in the same position as was the case in the »delivery« of the new clutch. → Fig.
