- Do not install when adjusting -B2-
11. Shim
- Do not install when adjusting -B2-
12. Retaining ring
- When adjusting -B2-, Insert with smooth side facing last inner plate (item 8) .

Shim Thickness, Determining
The thickness of the shim(s) is determined by gap x. Use the following formula





Gap x = a - b - 2.65 mm
Measuring points are shown in illustration to help understand formula. Special tool 3459, which exerts a force -F- onto plate packet via retaining ring, is not illustrated.
Dimension a, determining.
Dimension b, determining.
2.65 mm-Amount for settling is taken into account by force F.
1. ATF pump
2. Retaining ring
3. Plates for -B2- without last outer plate
4. Support tube

Note:
- First outer plate -arrow- and last outer plate are always 3 mm thick, do not install to measure!

Calculating Dimension "a":
Assemble planetary transmission up to the last -B2- inner plate. The last outer plate and shim are not installed.





- Place retaining ring with smooth side on last inner plate.
- Place 3459 on retaining ring and turn so 3 clips align with 3 holes for ATF pump.
- Bolt 3459 to flange for ATF pump with 5 Nm (44 inch lbs.).

Plate stack for -B2- is now pressed together for the measurement.





- Measure from pump flange/transmission housing -arrow- to 3459 with depth gauge.

Dimension a = Height of 3459 in mm minus (-) measured value





- Note calculated value a.
- Remove 3459.
- Remove retaining ring.

Dimension "b", Calculating
- Push piston into ATF pump to stop.
- Place new paper gasket on ATF pump.





- Place straightedge " B " on stator support -arrow- and measure with depth gauge "A" to gasket of pump flange.
- Note calculated value b.





Gap x = a - b - 2.65 mm
Gap x = 27.3 - 20.3 - 2.65 mm = 4.35 mm
- Determine size of shim(s) according to table:





Table of "Shims":
- Select shim(s) according to table and determine Part No. from parts catalogue.
In this example two shims must be installed (each 1.00 mm thick).

- Insert three spring caps on compression springs.
- Insert last outer plate -3 mm thick-.





- Install correct shim(s) -a-.
- Place retaining ring -b- on shim(s).
- Smooth side facing shim.
- Continue installation as described. Refer to Service and Repair.
