Air Gap, Calculating

WARNING: This page is about a different car, the 2014 Audi A5, 2013 Audi A5, 2012 Audi A5, and 2011 Audi A5. However, it is still accessible from the selected car via links, so may be relevant.

-- Use the following calculation to determine the air gap:

	Average of press plate measurements "M _D " (Value 1 + Value 2 + Value 3) : 3
-	Average of clutch measurements "M_K " (Value 1 + Value 2 + Value 3 + Value 4) : 4
=	Air gap

Air gap= "M_D " - "M_K "

Air gap specified value: 1.8 ± 0.2 mm.

If Specified Value Is Not Reached:

A - Measured value too small:

-- Insert the corresponding thinner adjustment plate, the lower adjustment plate must also be replaced, if necessary.

-- After installing, check the air gap of the new adjustment plate again. Refer to INPUT SHAFT, ADJUSTING BY DETERMINING AIR GAP .

B - Measured value too large:

-- Insert corresponding thicker adjustment plate; the lower adjustment plate must also be replaced, if necessary.

-- After installing, check the air gap of the new adjustment plate again. Refer to INPUT SHAFT, ADJUSTING BY DETERMINING AIR GAP .

The following adjustment plates are available:

Available Adjustment Plates [thickness in mm]
1.90	2.15	2.65
2.90	3.15

NOTE:

The air gap can be adjusted through the upper and lower adjustment plate.

If the Specified Value Is Reached:

-- Remove all adjustment plates, lining plates, outer clutch plates and the corrugated spring washer -5-, -4-, -3-, -2- and -1- from the input shaft cylinder -A-.

CAUTION:

This step is necessary because the corrugated spring washer -2 - is only installed over the lower adjustment plate -1- in order to adjust the input shaft. When assembling the input shaft, the corrugated spring washer is installed at the upper position.

-- Assemble the input shaft. Refer to INPUT SHAFT, DISASSEMBLING AND ASSEMBLING .
