Gap Dimension Between Belt and Clutch Plate, Checking

WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The gap dimension must be within the permissible range over the entire circumference.

Gap dimension may also be measured with A/C compressor installed.

If the gap dimension is outside of the permissible range, first remove the clutch plate and then remove or insert spacers to attain the correct dimension.

-- Remove the front noise insulation. Refer to OVERVIEW - NOISE INSULATION .

-- Release the tension on the ribbed belt and then remove it. Refer to RIBBED BELT, REMOVING AND INSTALLING .

The clutch plate -C- is tightened to the A/C compressor shaft -E- with the correct tightening specification (30 Nm).

-- Measure the dimension "1" between the belt pulley -B- and the clutch plate -C- with a depth gauge -F- at three places on the clutch plate -C- circumference and then write down the measured values.

-- Apply 12 volts to the 1-pin connector -A-.

-- Connect the ground to the compressor housing -D-.

-- Measure the dimension "2" between the belt pulley -B- and the clutch plate -C- with a depth gauge -F- at three places on the clutch plate -C- circumference and then write down the measured values.

-- Calculate the gap dimension using dimensions "1" and "2".

Specified value for gap dimension: 0.4 to 0.6 mm (up to 0.8 mm on a previously used A/C clutch).
