Tolerance variations make it possible to find the exact shim thickness required.

-- Remove the pinion with the old shims "S ₃ *" and "S ₄ *". Refer to PINION, REMOVING AND INSTALLING .

Warm the transmission housing with the Hot Air Blower in the area of the bearing seat -arrows- to approximately 100 °C (212 °F).
If necessary slightly cool the double angular contact ball bearing on the pinion for example with commercially available cooling spray.

-- Insert the determined shim "S ₃ *" -1- for example 0.97 mm in the transmission housing.

-- Then insert the pinion -3- quickly without tilting all the way in the transmission housing.

Determining the Thickness of the Shim "S ₄ "

Formula: "S ₄ " = 2.54 mm - "S ₃ "

Example:
	Constant value	2.54 mm
-	Shim thickness "S ₃ "	0.97 mm

Determine the shim "S ₄ " according to the table. Refer to Adjusting Shims Available for and .

-- Place the determined shim "S ₄ " -2- of for example 1.57 mm on the double angular contact ball bearing.

Installation position of the circlip -1- : the bevel -arrow- points upward and the flat side points to the double angular contact ball bearing.

-- Install the circlip -1- in the transmission housing groove all around.

Performing the measurement check, checking dimension "R"

-- Pinion installed with shims "S ₃ " and "S ₄ ".

-- Install the Universal Mandrel and perform measurement check.

-- Read out the measured value.

If adjustment shims were determined correctly, dimension "R" must have a clearance of ± 0.05 mm.

TIP:

Check one more time after removing the Universal Mandrel if the dial gauge, with the 2 mm pre-tension, is at "0" with the Measuring Set - Adjustable Master Gauge:VW 385/30 installed.
