Adjusting clutch play between -K1- and -K2-
Adjusting clutch play between -K1- and -K2-
This is the only adjustment work required for the installation of an exchange component.
   
Special tools and workshop equipment required
t  Support plate -VW 309-
t  Support clamp -VW 313-
t  Gearbox support -VW 353-
t  Universal dial gauge bracket -VW 387-
t  Depth gauge
t  Straightedge
t  Dial gauge

   
–  To adjust clutch play, install components without shim → Item ⇒ Assembling planetary gearbox → Chapter.
1 - Gearbox housing
q   → Planetary gearbox installed up to small input shaft ⇒ Assembling planetary gearbox → Chapter.
2 - Needle thrust bearing with washer
q   Needle thrust bearing faces small input shaft
q   Washer faces towards -K3-.
3 - 1st to 3rd gear clutch -K1- and 3rd and 4th gear clutch -K3- with turbine shaft
q   In some gearboxes, → clutches -K1- and -K3- may be pressed together as shown here.
q   There are two different types of turbine shaft, depending on the torque converter installed → Chapter.
4 - Shims
q   Do not install when adjusting clutch play
q   Up to 3 shims can be installed
q   Shims are colour-coded according to thickness
5 - Reverse gear clutch -K2-
q   Does not need to be installed for determining the shim(s)
q   Install for check measurement.

Calculating thickness of coloured shims
–  Observe general repair instructions → Chapter.
Prerequisites:
l  Planet carrier is installed and adjusted ⇒ Assembling planetary gearbox → Chapter, Installing exchange component → Chapter
l  Gearbox housing must be turned in assembly stand with input gear downwards for checking dimensions, as shown in → Item.
   
Shim to be measured -A-
A - Coloured shims
1 -  → ATF pump
2 - Reverse gear clutch -K2-
3 - 1st through 3rd gear clutch -K1-
4 - 3rd and 4th gear clutch -K3-
–  Calculate thickness of shim. Determine gap “x” and calculate shim thickness.
Gap x = a - b
Calculating a:
l  Gearbox housing must be turned in assembly stand with input gear downwards for checking dimensions, as shown in → Item.
  N37-0038
–  Place straightedge -A- on gearbox housing.
–  Press -K1- downwards in direction of arrow and measure into -K1- using depth gauge -B-.
Example:
Measured value 1 = 88.5 mm
  N37-0217
–  Measure with depth gauge -B- to pump flange on gearbox housing.
Example:
Measured value 2 = 34.3 mm
  N37-0218
Measured value 1=88.5 mm
- Measured value 2=-34.3 mm
Calculated value a=54.2 mm

= Value measured from pump flange/gearbox housing into -K1-.
Calculating b:
–  Place new paper gasket on → ATF pump.
   
–  Place straightedge -B- on top of stator support -arrow- and measure with depth gauge -A- to gasket of pump flange.
Example:
  N37-0055
Measured value=70.5 mm
- Straightedge=-19.5 mm
Calculated value b=51.0 mm

Gap x = a - b
= 54.2 mm - 51.0 mm = 3.2 mm
–  Determine shims according to table → Anchor.
–  Check clutch play dimension after installing → ATF pump → .
Table of shims:
   
Gap-x- (mm)Thickness of required shims (mm)Colour of required shims
… 2.54
2.55 … 3.09
3.10 … 3.49

1.2 + 1.2

Green + green
3.50 … 3.89
3.90 … 4.29

1.4 + 1.4
1.6 + 1.6
1.8 + 1.8

Black + black
Grey + grey
4.70 … 5.04
5.05 … 5.25
1.2 + 1.2 + 1.6
1.2 + 1.2 + 1.8
Green + green + black
Green + green + grey

–  Determine thickness of shim from table.
Shims have different thicknesses.
   
Blue=1.0 mm
Green=1.2 mm
White=1.4 mm
Black=1.6 mm
Grey=1.8 mm

In the previous example, it was calculated that x = 3.2 mm. Consequently, two green shims would be used in this example.
If an exchange component is used:
The exchange component contains shims of various colours and thicknesses to adjust the play between -K1- and -K2-.
–  Select required shim; there are enough included in the exchange component.
Measurement to check clutch play
–  The clutch play cannot be measured until the → ATF pump has been installed.
–  Attach dial gauge holder to gearbox housing and place dial gauge on turbine shaft with 1 mm preload.
   
–  Move turbine shaft up and down and read play on dial gauge.
Play:
min. = 0.5 mm
max. = 1.2 mm
