911 Carrera Coupe F6-3600cc Transmission: Automatic Intermediate Plate Diagram
Intermediate Plate: Adjustments
Adjusting the preload of the spur gear taper roller bearings
Adjusting spur gear II (intermediate gear)
1. Determine and record dimension "a" (e.g. 45.90 mm).
2. Fit complete spur gear II and determine dimension "b" (e.g. 44.65 mm). Record measured value.
3. Determine shim thickness by deducting dimension "b" from dimension "a" and adding a constant value of 0.22 mm (preload and thickness of
compressed gasket).
NOTE: The constant value is 0.22 mm for all transmissions.
Example
Dimension "a" e.g.
45.90 mm
Dimension "b" e.g.
-44.65 mm
____________
1.25 mm
Constant
+0.22 mm
_____________
Shim thickness
1.47 mm
NOTE: Always round shim thickness up or down to the nearest 0.05 mm figure.
Adjusting spur gear I (drive gear)
1. Remove intermediate plate.
2. Remove adjusting shim.
3. Remove spur gear II (intermediate gear) for measurement.
4. Bolt up cover with intermediate plate (but without gasket).
-
Tighten all screws and bolts to: 23 Nm (17 ft lb).
5. Internal puller (e.g. Schrem 20 - 30) into spur gear teeth.
6. Fit dial gauge holder VW 387 with dial gauge and zero out dial gauge with a preload of 2 mm.
