1. Disconnect ground wire from battery.
2. Remove the air filter with pipes.
3. Drain the engine oil by unscrewing the drain plug in the oil pan.
4. Remove the elastic pipes of the cooling system connected to the cylinder head.
5. Disconnect all electrical wires from the cylinder head.
6. Disconnect the fuel lines and plug them immediately with appropriate plugs.
7. Unscrew the nuts securing the fuel pump and remove the pump.
8. Remove the accelerator pedal and starter linkages from the carburetor.
9. Remove the valve cover and remove the two spacers as well as the sheet casing (oil reflector).
10. Piston 1st cylinder (counting from the flywheel) set to TDC (both valves of the 1st cylinder are closed).
11. Engage 4th or 5th gear and apply the handbrake.
12. Disconnect the exhaust pipe from the exhaust manifold.
13. Unscrew the mounting bolts and remove the three-piece toothed belt guard.
14. Loosen the tensioner roller and carefully remove the toothed belt, being careful not to bend it.
15. Unscrew the cylinder head bolts in several stages in order, from the middle outwards.
16. Remove all five valve lever axle brackets with levers and axle.
17. Tilt the cylinder head with two bent rods around one of the bottom long edges of the head to separate it from the cylinder block.
18. Carefully remove the cylinder head gasket.
19. Attach the cylinder liners to the cylinder block with two special Peugeot plates (1) (tool 0132 A1Z), screwing each plate with two M10 bolts 40 mm long.
Attention! The last three operations should be carried out very carefully so as not to accidentally lift the cylinder liners from the sockets in the cylinder block, because. this can lead to contamination of the contact surface and loss of tightness of the connection. If the cylinder liners are lifted, the engine must be completely removed and then installed correctly.
20. Clean the upper surface of the cylinders from drops of oil and coolant.
