Calculating "a":

WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.

For the measuring sequence, the transmission housing must be clamped into assembly stand so input gear is facing downward.

Place straightedge "A" onto transmission housing.

Press -K1- down in direction of arrow and measure distance into -K1- with depth gauge "B".
Example:

Reading 1 = 88.5 mm

Measure with depth gauge "B" to pump flange on transmission housing.

Example:

Reading 2 = 34.3 mm

CALCULATING A (CLUTCH PLAY BETWEEN -K1- AND - K2-)

Reading 1 - Reading 2	= =	88.5 mm - 34.3 mm
Calculated size a	=	54.2 mm

= Size measured from pump flange/transmission housing into -K1-.
