Adjusting preload of ball bearing for flange shaft (left-side) — AUDI

🧭 Before you start

Fits: Audi A5 Cabriolet (8F), Audi A5 (8T, 2007–2016), Audi A4 B8 (8K, 2007–2015), Audi A6/A7 C7 (4G, 2011–2018); platform code 4X

• Special tools named: VAS 6075, feeler gauge
• Renewed: mounting bracket

Don't miss

• The contact surface does not have to be sanded down to bare metal; it is sufficient to remove coarse dirt and corrosion.
• The smallest of the 4 measured values is used to determine the shim(s).
• The largest of the 4 measured values is used to determine the shim(s).The measured distance below the contact surface is taken as a minus value ("“–”") for the calculation.
• Before installing flange shaft fit calculated number of shims 0B4 409 227(item 1) in bearing seat in gearbox.

📋 Procedure

1. Attach emery cloth (grain size 150) to sanding block and clean coarse dirt and corrosion off contact surface (arrow). [Note: The contact surface does not have to be sanded down to bare metal; it is sufficient to remove coarse dirt and corrosion.]
2. Clean contact surface and bearing seat.
3. Fit new ball bearing (arrow) for flange shaft (left-side) in bearing seat.
4. Apply straight edge (500 mm)VAS 6075 across bearing and measure distance to contact surface on gearbox housing on both sides using feeler gauge.
5. Note down measured value.

6. Re-apply straight edge at an angle of 90° across bearing and measure distance to contact surface on gearbox housing on both sides using feeler gauge.
7. Note down measured value. [Note: The smallest of the 4 measured values is used to determine the shim(s).] [Note: Use only the method described here to measure the distance below the contact surface.]
8. Apply straight edge (500 mm)VAS 6075 across contact surface on gearbox housing and measure distance to bearing on both sides using feeler gauge.
9. Note down measured value.
10. Re-apply straight edge at an angle of 90° across contact surface on gearbox housing and measure distance to bearing on both sides using feeler gauge.
11. Note down measured value. [Note: The largest of the 4 measured values is used to determine the shim(s).The measured distance below the contact surface is taken as a minus value ("“–”") for the calculation.]
12. Renew mounting bracket, ball bearing and circlip .
13. Before installing flange shaft fit calculated number of shims 0B4 409 227(item 1) in bearing seat in gearbox.
14. Install flange shaft (left-side) .
