Adjusting output shaft for 5th, 6th and reverse gear: Audi A1

🧭 Before you start

Fits: Audi A1 (8X, 2010–2018)

• Special tools named: dial gauge
• Also covered elsewhere: Electronic parts catalogue

📋 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. Insert complete 5th, 6th and reverse gear output shaft in clutch housing.
3. Fit gearbox housing and tighten bolts (A) and (B) diagonally to correct torque.
4. Attach measuring equipment. Put washers of a total thickness of 8 mm on bolt (arrow) securing assembly deviceVW 792 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: 0.25 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) for performing the measurement.Select correct shims from Electronic parts catalogue.]
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. For part numbers, refer to Electronic parts catalogue.
12. Press in tapered roller bearing outer race together with the correct shim (in example 1.65 mm). Support gearbox housing with thrust piece2050 directly below bearing mounting.
13. Attach measuring equipment. Put washers of a total thickness of 8 mm on bolt (arrow) securing assembly deviceVW 792 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.
