Procedure If There Is Bearing UNDERSIZE

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Audi S5, 2014 Audi S5, 2013 Audi S5, 2012 Audi S5, and 2011 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The bearing undersize can only be determined in the described procedure.

-- Place VAS 6075 straight across the contact surface on the transmission housing and measure the distance to the bearing on both sides with a feeler gauge.

-- Write down the measured value.

-- Place VAS 6075 offset across the contact surface on the transmission housing and measure the distance to the bearing on both sides with a feeler gauge.

-- Write down the measured value.

Selecting Shim(s):

NOTE:

Use the largest value take from the four values to select the shim(s).

Enter the measured bearing undersize as negative value ("-") into the calculation.

Specified value, bearing oversize = 0.5 to 0.8 mm

-	Larger determined bearing undersize (example -0.15 mm)
+	Shim(s) thickness, (thickness = 0.3 mm)
=	Bearing pre-load (specified value = 0.5 to 0.8 mm)

Example:

1 shim:

-0.15 mm + 0.3 mm = 0.15 mm, "bearing pre-load is too small"

3 shims:

-0.15 mm + 0.3 mm + 0.3 mm + 0.3 mm = 0.75 mm, "bearing pre-load is in the specified range"

Result: A 0.75 mm bearing pre-load within the specified value of 0.5 to 0.8 mm is reached by installing three 0.3 mm shims.

-- Replace the bearing bracket, the ball bearing and the circlip. Refer to LEFT FLANGE SHAFT BALL BEARING MOUNTING BRACKET .

-- Insert the determined number of shims 0B4 409 227 -1- into the bearing seat on the transmission before installing the flange shaft.

-- Install the left flange shaft. Refer to LEFT FLANGE SHAFT .
