Engine disassembly — general part (Peugeot 305)

1. It is best to disassemble the engine on a clean work bench. Before installing the engine and gearbox on the table, they should be cleaned from the outside from dirt, oil and grease.

2. Be careful not to bring dirt inside the engine.

3. Clean the engine from dirt, for example with kerosene.

4. Wipe the engine with a rag and dry it. After this, you can begin disassembling.

5. As you disassemble the engine, inspect its parts briefly before washing in kerosene and drying. This inspection is necessary because it can determine the condition of the engine. It is prohibited to immerse parts with internal channels in kerosene (for example, a crankshaft). Such parts are cleaned with a cloth soaked in kerosene, and the internal channels are cleaned with wire. If necessary, blow out the channels with compressed air.

6. During assembly, all gaskets and seals must be replaced with new ones.

7. Do not throw away old gaskets, as they can serve as a sample for making new ones.

8. We suggest disassembling in the following sequence: remove the clutch, then the valve timing mechanism (if desired, you can swap these operations). After this, disconnect the gearbox, remove the cylinder head, then the crankshaft and connecting rods with pistons. During the process, you can support the engine with wooden blocks.

9. Whenever possible, replace bolts, washers and nuts in their original locations and tighten them by hand. This will prevent you from losing or mixing up fasteners that cannot be installed in place; they should be laid out so that it is immediately clear where they were removed from.
