Adjusting output shaft for 1st - 4th gear: Audi A1

🧭 Before you start

Fits: Audi A1 (8X, 2010–2018)

• Special tools named: dial gauge

Don't miss

• If no play is indicated on dial gauge when clutch housing/gearbox housing securing bolts are loosened, fit a 1.95 mm shim (or if necessary a 2.20 mm shim) Electronic parts catalogue for performing the measurement.

📋 Procedure

1. Press tapered roller bearing outer race with shim (thickness 1.70 mm) into gearbox housing. Support gearbox housing with thrust piece2050 directly below bearing mounting.
2. Fit complete 1st to 4th gear output shaft into clutch housing.
3. Fit gearbox housing and tighten bolts (A) and (B) diagonally to correct torque.
4. Set up measuring tools and secure with bolt (arrow) to clutch housing.
5. Set dial gauge (3 mm measuring range) to "“0”" with 1 mm preload.

6. Loosen clutch housing/gearbox housing securing bolts diagonally until output shaft is free to move in gearbox housing.
7. Read off play on gauge and note reading (example: 0.14 mm). [Note: If no play is indicated on dial gauge when clutch housing/gearbox housing securing bolts are loosened, fit a 1.95 mm shim (or if necessary a 2.20 mm shim) Electronic parts catalogue for performing the measurement.]
8. Determine thickness of shim from table .
9. Detach gearbox housing and pull tapered roller bearing outer race out of gearbox housing.
10. Remove inserted shim (1.70 mm thick) from gearbox housing.
11. Determine part number of shim from Electronic parts catalogue.
12. Press in tapered roller bearing outer race together with the correct shim (in example 1.75 mm). Support gearbox housing with thrust piece2050 directly below bearing mounting.
13. Set up measuring tools and secure with bolt (arrow) to clutch housing.
14. Set dial gauge (3 mm measuring range) to "“0”" with 1 mm preload.
15. Loosen clutch housing/gearbox housing securing bolts diagonally until output shaft is free to move in gearbox housing.
16. If the correct shim has been selected, the dial gauge should now indicate a value between 0.15 and 0.25 mm.
