Description

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

The clearance is measured using a dial gauge. Incorrectly adjusting the axial clearance can lead to significant, irreparable engine damage. The clearance is adjusted with adjusting rings located behind the flywheel, where the axial clearance is first adjusted and then the crankshaft seal is assembled.

It is important to always install three rings. The adjusting rings are available in different thicknesses to allow for precise adjustment. Never use old worn rings, rings with burrs, or rings that are no longer flat, as this can prevent correct adjustment.

The inner diameter of these rings is 53.6 mm. Make sure to measure this for Type 1 and Type 3 engines before ordering to ensure that your engine actually dates from after the specified year of manufacture. 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 numbers in 1966 the rings with an inner diameter of 53.6 mm were applied.

Type 1 engines:

1200 cc D 0 076 332

1300 cc E 0 004 201

1300 cc F 0 741 385

Type 3 engines:

1500 cc K 0 040 817

1500 cc M 0 000 300

1600 cc T 0 210 167

1600 cc P 0 000 800
