a1 - Refitting the exhaust side seal
aPosition the protector fitted with a new seal (7) on
the camshaft (taking care not to touch the seal).
aScrew the stud (8) of the (Mot. 1632) onto the cam-

Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
WARNING
The joint faces must be clean, dr y and free from
grease (avoid finger marks).

Note:
Always hold the camshaft seal with the protector
(5) when handling, as this type of camshaft seal
is very FRAGILE. Touching the camshaft seal (6)
is strictly forbidden in order to avoid any oil leaks
once the camshaft seal is fitted on the engine.
