Install front crankshaft radial seal - AR03.20-P-3000-01QP

Fig 1: Identifying Drift (271 589 01 15 00)

1. Debur edge of mounting bore for crankshaft radial sealing ring at timing case cover.
2. Fit crankshaft radial sealing ring onto side (a) of drift (2).

   Circumference and sealing lip of crankshaft radial seal as well as the mating contact surface on the vibration damper must be free of oil and grease.

3. Align groove of drift (2) to parallel key of crankshaft.

   Secure through rotary movements, that the groove of the drift (2) matches with the parallel key in the crankshaft, otherwise damage could occur to the parallel key.

4. Push drift (2) onto crankshaft and press in crankshaft radial sealing about 2 mm by hand.
5. Knock crankshaft radial sealing ring into crankcase with light blows from a hammer, until the lower edge of the drift (2) is resting on the crankcase.
6. Take off drift (2).

The crankshaft radial sealing ring must be positioned at right angles to the crank journal (3) otherwise proper sealing is not assured.

The installation depth (B) of the crankshaft radial sealing ring (1) is fixed by the drift (2) and must not be altered subsequently.
