–	When adjusting clutch play install components without shim → Item → Chapter „Assembling planetary gearbox“.

1 -	Gearbox housing

q	Planetary gearbox installed up to small input shaft → Chapter „Assembling planetary gearbox“.

2 -	Axial needle bearing with washer

q	Axial needle bearing faces towards small input shaft.

q	Washer faces towards -K3-.

3 -	3rd and 4th gear clutch -K3- with turbine shaft

q	Clutches -K1- and -K3- can be pressed together in some gearboxes.

4 -

O-ring

5 -	1st to 3rd gear clutch -K1- with turbine shaft

q	Clutches -K1- and -K3- can be pressed together in some gearboxes.

6 -

Shims

q	Do not install when adjusting clutch play.

q	1 or 2 shims can be installed.

7 -	Reverse gear clutch -K2-

Prerequisites: l  Planet carrier is installed and adjusted → Chapter „Assembling planetary gearbox“ l  Gearbox housing must be turned in assembly stand with input gear downwards for the measuring procedure, as shown in → Chapter.

Determining shim -A- A -  Shim 1 -  ATF pump 2 -  Reverse gear clutch -K2- 3 -  1st to 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 the measuring procedure, as shown in → Chapter.

–  Place straight edge “A” onto gearbox housing. –  Press -K1- down together with -K3- in direction of arrow and measure into -K1- with depth gauge “B”. Example: Measured value 1 = 88.5 mm

–  Measure with depth gauge “B” to pump flange on gearbox housing. Example: Measured value 2 = 34.3 mm

Measured value 1	=	88.5 mm
- Measured value 2	=	- 34.3 mm
Calculated value a	=	54.2 mm

= Size measured from pump flange/gearbox housing into -K1-. Calculating b: –  Place new paper gasket onto ATF pump.

–  Place straight edge -B- onto stator support -arrow- and measure with depth gauge -A- to gasket of pump flange. Example:

Measured value	=	70.5 mm
- Straight edge	=	- 19.5 mm
Calculated value b	=	51.0 mm

Gap x = a - b = 54.2 mm - 51.0 mm = 3.2 mm –  Determine size of shims according to table: Table of shims

Gap “x” (mm)	Shims (mm)
… 2.54 2.55 … 3.09 3.10 … 3.49	1.4 1 + 1 1.2 + 1.2
3.50 … 3.89 3.90 … 4.29 4.30 … 4.69	1.4 + 1.4 1.6 + 1.6 1.8 + 1.8
4.70 … 5.04 5.05 … 5.25	1.2 + 1.2 + 1.6 1.2 + 1.2 + 1.8

–  Ascertain thickness of shim according to table and determine part no. from parts catalogue. –  Carry out clutch play check measurement after installing ATF pump. Check measurement (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 a preload of 1 mm.

–  Move turbine shaft up and down and read off play on dial gauge. Play: min. = 0.5 mm max. = 1.2 mm
