Engine removal and overhaul procedures / Engine overhaul - reassembly sequence


1 Before reassembly begins, ensure that all new parts have been obtained, and that all necessary tools are available. Read through the entire procedure carefully to familiarise yourself with the work involved, and to ensure that all items necessary for reassembly of the engine are at hand. In addition to all normal tools and materials, thread-locking compound will be needed. A suitable tube of liquid sealant will also be required for the joint faces that are fitted without gaskets. It is recommended that Peugeot’s own product(s) are used, which are specially formulated for this purpose.

2 In order to save time and avoid problems, engine reassembly can be carried out in the following order:
a) Crankshaft (Section 18).

b) Piston/connecting rod assemblies (Section 19).

c) Oil pump .

d) Sump (See Part A or B - as applicable).

e) Flywheel (See Part A or B - as applicable).

f) Cylinder head (See Part A or B - as applicable).

g) Timing belt tensioner and sprockets, and timing belt (See Part A or B - as applicable).

h) Engine external components.

3 At this stage, all engine components should be absolutely clean and dry, with all faults repaired. The components should be laid out (or in individual containers) on a completely clean work surface.
