Replace in the following order:

- Unscrew the bearing front cover and remove the sealing ring;

- Apply sealant to the separable surfaces of the front bearing cover and put the cover back on. Alternately tighten the cover fasteners now on the right, then on the left with a torque of 10 Nm and tighten again from the end position with a torque of 19 Nm;

- install a new oil seal on the camshaft, or rather, press it in with a piece of pipe with a diameter of the sealing ring. An M10 screw and a large washer are screwed onto the pipe to press the stuffing box onto the shaft. Lubricate the sealing lips well;
