911 Carrera Coupe F6-3164cc 3.2L (1984)
Camshaft Gear/Sprocket: Adjustments
Checking Parallel Of Sprockets
Deviation in parallel between the driving sprocket on the intermediate shaft and driven sprocket on the camshaft must not exceed ± 0.25 mm. Before
measuring move intermediate shaft and camshafts in axial direction toward flywheel to position guiding collar of bearings.
Sprockets are adjusted by adding or removing shims, Part No.901.105.561.00. Shim thickness: 0.5 mm.
Normally 3 shims will be required underneath the left sprocket (cyl. 1 - 3) and 4 shims underneath the right sprocket (cyl. 4 - 6).
Adjusting
1. Measure distance "A" from front edge of crankcase or lineal to face of intermediate shaft.
Design distance of drive gears on intermediate shaft:
From face of intermediate shaft:
to face of rear intermediate shaft sprocket (cyl. 1 - 3) = 98.07 mm
to face of front intermediate shaft sprocket (cyl. 4 - 6) = 43.27 mm
Design distance + measured distance "A" produces position of sprockets on camshafts (max. permissible deviation = ± 0.25 mm).
Example: Measured distance "A" = 35.5 mm
