The axial clearance of the crankshaft must be adjusted between 0.07 and 0.13 mm, with a wear limit at 0.15 mm.

The clearance is measured using a dial gauge. Not accurately adjusting the axial clearance can lead to significant, irreversible engine damage. The clearance is adjusted using adjustment rings located behind the flywheel, with the axial clearance being adjusted first, followed by the installation of the crankshaft seal.

It is crucial to always install three rings. The adjustment rings are available in various thicknesses to allow for precise adjustment. Never use old worn-out rings, rings with burrs, or rings that are no longer flat, as this will prevent correct adjustment.

The inner diameter of these rings is 53.6 mm. Measure this for Type 1 and Type 3 engines before ordering to ensure that your engine actually dates from after the specified year of construction. For Type 4 or WBX engines, this measurement is not necessary, as they have never been changed. Below is the exact information on which engine number from 1966 the rings with an inner diameter of 53.6 mm have been applied.
