Audi Workshop Service and Repair Manuals

Dismantling and assembling clutch “C”

Dismantling –  Turn ATF supply unit upside down. –  Remove circlip -1- and remove set of plates -2- from cylinder “C”.

–  Press dished spring down using workshop press with mounting bracket -T10289-. –  Remove split retaining ring -1-. –  Release workshop press.

–  Detach dished spring -5-.

WARNING Wear safety goggles. –  Carefully press piston “C” out of ATF supply unit by applying compressed air.

Assembling   Caution Before assembly, check the individual components of clutch “C” for traces of wear and damage → Chapter. –  Renew O-rings -2- and -4- for piston “C”-item 3-. –  Insert piston “C”-item 3- into ATF supply unit -item 1- as far as stop. –  Fit dished spring -5-. 6 -  Split retaining ring

–  Press dished spring down using workshop press with mounting bracket -T10289-. –  Insert split retaining ring -1-. l  Collar of split retaining ring faces downwards. –  Release workshop press.

–  Insert corrugated spring -2- into cylinder “B”-item 1-. –  Fit outer plates -3- and friction plates -4- alternately. –  Insert thick outer plate -5-.   Note Make sure that the rounded edges of the thick outer plate face friction plate -4- and not circlip -6-. The contact surface for the circlip is thus increased. –  Insert circlip -6-.

Adjusting clearance of clutch “C” –  Clamp support leg of compressor tool -T10285- in vice. –  Place ATF supply unit on compressor tool. l  The stator shaft projects out of the drilling in the base plate. –  Position holding plate -T10295- onto outer plate of clutch “C”. l  Avoid any contact between holding plate and circlip. –  Fit centring pin of thrust piece -T10285/1- into drilling in holding plate. –  Bring ATF supply unit into correct position on holding plate of compressor tool. l  Thrust piece must be positioned centrally below thrust plate of spindle. –  Turn spindle of compressor tool downwards. l  The markings on the inspection hole of the thrust piece must align -arrow-. –  Apply digital depth gauge -VAS 6087- to upper rim of outer plate carrier “C” as shown in illustration. –  Bring measuring tip into contact with outer plate and note value obtained. –  Mark contact point on outer plate carrier “C”. –  Repeat measurement at two other points on outer plate (offset by 120°) and mark measuring points. –  Determine average value from the three measurements under load. –  Release spindle and remove holding plate.

–  Use both hands to pull set of plates upwards as far as possible in clutch “C”. –  With set of plates pulled up as far as stop, measure distance between upper rim of outer plate carrier “C” and outer plate at one of the points marked (assistance of second mechanic required). –  Repeat measurement at the two remaining markings on the outer plate. –  Determine average value from the three measurements with set of plates pulled up as far as stop. –  Determine clearance using the following formula:

	Mean value of measurements under load (value 1 + value 2 + value 3) : 3
–	Mean value of measurements with set of plates pulled up as far as stop (value 1 + value 2 + value 3) : 3
=	Clearance

–  Subtract mean value of measurement with set of plates pulled up as far as stop from mean value of measurements under load.

If reading does not match specification: –  Determine new circlip -1- according to following table.   Note -Item 2- can be disregarded. l  If clearance is below specification: insert thinner circlip of appropriate thickness. l  If clearance is above specification: insert thicker circlip of appropriate thickness.

Available circlips - Thickness of circlips in mm
1.2	1.8	2.4
1.4	2.0	2.6
1.6	2.2	2.8

–  Check clearance again after inserting circlip.
