Adjusting 2nd and 4th gear-brake B2 on gearboxes with wave spring washer on the last outer plate
   
Adjusting 2nd and 4th gear-brake -B2- on gearboxes with wave spring washer on the last outer plate
This setting instruction only applies to gearboxes with a wave spring washer Pos. 11 on the last outer plate Pos. 10 installed in the brake -B2-.
  Note
t  On these gearboxes, the clearance of the brake -B2- is determined by the thickness of the adjusting washer(s).
t  Install components for adjustment without wave spring washer Pos. 11, without last outer plate Pos. 10 and without helical springs Pos. 6.

Determine the thickness of the outer plate -D-
The thickness of the last outer plate is determined by the gap size “x”. For this purpose observe the following formula:
   
Gap size x = a - b - 3.6 mm
D - Outer plate(s)
x - Gap size
a - Installation depth of 2nd and 4th gear-brake -B2-; determine → Anchor
b - Housing measurement of ATF pump; determine → Anchor
  Note
t  The illustration shows the assembled brake -B2- in section. The adjusting device -3459 -, which exerts a force on the plate package, is not shown.
t  The value “3.6 mm” is considered the setting amount through the force of the adjusting device -3459-.
t  The first outer plate -arrow- is 3 mm thick.
Determine dimension a:
Assemble planetary gear up to the last inner plate of the -B2-, → Anchor. The last outer plate, the last 3 helical springs and the wave spring washer are not installed!
–  -3459- position on the last outer plate and turn until the 3 clamps are flush with the 3 holes for the ATF pump.
–  -3459- screw on with 5 Nm at flange for ATF pump.
Thus the plate package of the -B2- is pressed together for the measurement.
  A37-0191
–  Measure from pump flange/gearbox housing -arrow- on -3459- with depth gauge.
Dimension -a- = height of the -3459- in mm - measuring value
Example:
  N37-0529
Height of the adjusting device -3459-=60.0 mm
- measured value=- 29.8 mm
determined value a=30.2 mm

–  Note the determined value for a.
–  Remove -3459-.
Determine dimension b:
–  Press the piston up to the stop into the ATF pump.
–  Fit paper gasket on the ATF pump flange.
   
–  Position straightedge -B- at the bottom of the guide wheel support -arrows- and measure with depth gauge -A- on the gasket of the pump flange.
Example:
  N37-0222
measured value=40.1 mm
- Straightedge=- 19.5 mm
determined value b=20.6 mm

–  Note the determined value for b.
Gap size x = a - b - 3.6 mm
Gap size x = 30.2 - 20.6 - 3.6 mm = 6.0 mm
–  Determine the thickness of the outer plate(s) according to the table:
Table of outer plates:
   
Gap size “x” (mm)Plate (mm)
4,25 … 4,49
4,50 … 4,74
4,75 … 4,99		2,75
3,00
3,25
5,00 … 5,24
5,25 … 5,49
5,50 … 5,74		3,50
3,75
2,00 + 2,00
5,75 … 5,99
6,00 … 6,24
6,25 … 6,49		2,00 + 2,25
2,25 + 2,25
2,25 + 2,50
6,50 … 6,74
6,75 … 7,00		2,50 + 2,50
2,50 + 2,75

–  Establish the thickness of the adjusting washer(s) according to table and determine the spare part number via the → Electronic Catalogue of Original Parts.
In this example two adjusting washers (each 2.25 mm thick) must be installed.
–  Position three helical springs on the pressure springs.
–  Insert determined, last outer plate(s).
–  Insert wave spring washer.
–  Further assembly is described as of → Anchor.
