Skoda Workshop Service and Repair Manuals

III - Adjust the clutch clearance between -K1- and -K2- Special tools and workshop equipment required t  Universal dial gauge holder -MP3-447 (VW 387)-

This is the only adjusting work when installing an exchange component → Chapter.

–	Install components for adjusting the clutch clearance without adjusting washer Pos. 4 and reverse gear-clutch Pos. 5.

1 -	Gearbox housing

q	Planetary gear fitted up to small drive shaft → Anchor

2 -	Axial needle bearing with washer

q	Axial needle bearing points to the small drive shaft

q	Washer points to -K3-

3 -	1st up to 3rd gear - clutch -K1- with 3rd and 4th gear - clutch -K3- with turbine shaft

q	on certain gearboxes, the clutches -K1- and -K3- can be pressed together as shown here

q	there are two different versions of turbine shafts, depending on the installed converter → Chapter

4 -

Shims

q	do not install to adjust the clutch clearance

q	up to 3 adjusting washers can be installed

q	washers are available in different colours depending on the thickness

5 -	Reverse gear - clutch -K2-

q	must not be installed necessarily for determining the adjusting washer(s)

q	install for control measurement

Determining the thickness of the adjusting washer(s) -C- l  Planet carrier installed and adjusted → Anchor. l  The gearbox housing must be turned downwards with the drive gear in the assembly support for the measurement. The thickness of the adjusting washer(s) depends on the gap size -x-. It is determined according to the following formula:    -x- = -a- – -b- 1 -  ATF-pump 2 -  Reverse gear - clutch -K2- 3 -  1st up to 3rd gear - clutch -K1- 4 -  3rd up to 4th gear - clutch -K3- C -  Adjusting washer(s) x -  Gap size a -  Installation depth of clutch “K1”; determine → Anchor b -  Housing measurement of ATF pump; determine → Anchor Determining value “a”:

–  Place straightedge -A- on the gearbox housing. –  -K1- in -direction of arrow- press downwards and measure with depth gauge -B- in the -K1-. Example: Measured value 1 = 88.5 mm

–  Place straightedge -A- on the gearbox housing. –  Measure on pump flange at gearbox housing with depth gauge -B-. Example: Measured value 2 = 34.3 mm Calculation example value “a”

Measured value 1	=	88.5 mm
- Measured value 2	=	- 34.3 mm
determined value “a”	=	54.2 mm

Determining value “b”: –  Fit new paper gasket on the ATF pump.

–  Position straightedge -B- on the top of the guide wheel support -arrow- and measure with depth gauge -A- on pump flange. Example:

measured value	=	70.5 mm
- Straightedge	=	- 19.5 mm
determined value “b”	=	51.0 mm

Gap size x = a - b x = 54.2 mm - 51.0 mm = 3.2 mm
