Removing

3. Remove the pump cover.



4. Remove the pump housing from the crankcase.



5. Remove the sealing ring.

We assemble and install in the reverse order. Before assembly, we clean the surfaces of the cover and body from the old gasket. Install new gasket and O-ring.

Tighten the mounting bolts to a torque of 10 Nm.
