Disassembling Engine

→ Wear personal protective gear.

→ Get someone to help if necessary.

→ Secure components to prevent them from falling down.

→ Since the bucket tappets have been run in the fitting bores, do not interchange them.

→ Absolute cleanliness is essential.

Information 

Have a collection pan and some cloths ready before starting work on the engine block. Close off open hoses immediately after opening them using suitable stoppers. Residual fluid can leak out.

Information 

Support the engine at the oil pan or engine carrier using suitable lifting equipment and a wide wooden block.

Information 

For many components, it is only necessary to partially disassemble the engine. The extent of disassembly depends on the damage and scope of repairs to be carried out.

When replacing the cylinder head gasket, many components, such as the vacuum pump, injectors and exhaust manifolds, remain on the cylinder head. In this case, the cylinder head can be lifted from the crankcase with all components intact.
