Removing Crankshaft

→ Absolute cleanliness is essential when working on the engine.

→ Lay removed engine parts on a clean base and make sure to cover them.

→ Use the cover for dust protection when fitting the engine NR.165  on the engine assembly support.

→ The holding wrench must make contact with the pulley when tightening.

→ Get another person to help.

1. Loosen the pulley. To do this, a second person should counter with the relevant holding wrench at the same time. Do not re-use the hexagon-head bolt.
