Tighten the timing belt by tightening one bolt (B)
on the inner timing cover.
99174-2R1
Fit tool Mot. 1273 and tension the belt until the
fitting tension is obtained (see section 07, Timing
belt tension ).
Tighten the tensioner nut to 5 daN.m.
It is vital to tighten the tensioner nut to 5 daN. m
to avoid any loosening of the tensioner which
could damage the engine.
Refit the crankshaft pulley and ensure the bolt is
tightened to a torque of 12 daN.m.
Refitting is then the reverse of removal.
Fit the suspended mounting cover assembly and
the movement limiter.
ADJUSTING THE LONGITUDINAL MOVEMENT
LIMITER
Slacken limiter bolts (4).
Insert the limiter centring fork Mot. 1289-03 into
the openings in the suspended mounting cover.
Tighten the limiter bolts (4) to a torque of
5.5 daN.m.
Check the injection pump timing (see section 13,
injection pump).

CLEANING
It is very important not to scratch the gasket faces
of parts in aluminium.
Use Décapjoint to dissolve any gasket remaining
on the metal.
Apply the product to the area to be cleaned; wait
approximately ten minutes then remove using a
wooden spatula.
Gloves should be worn during this operation.
Remember that this operation should be carried
out with extreme care to avoid the risk of foreign
bodies being introduced into the oilways bringing
oil under pressure to the rocker shaft (oilways are
located in both the cylinder head and the cylinder
block).
If this recommendation is not observed there is a
risk that the rocker jets may become blocked and
damage may occur rapidly to the rocker cams and
tappets.

CHECKING THE GASKET FACE
Use a straight edge and a set of shims to check for
gasket face deformation.
Maximum bow 0.05 mm.
The cylinder head may not be re-ground.
REFITTING (Special notes)
Remove the liner retaining flanges Mot. 588
(except K7M).
Wipe the gasket faces of the cylinder block and
the cylinder head.
Check the centring dowel is present (G).

Position the cylinder head gasket.
Refit the cylinder head, lubricate the threads and
the bearing faces under the heads of the bolts
with engine oil.
Note : check the length of the bolts for the
cylinder head, the shorter ones are used on the
inlet side.
Cylinder head tightening (see section 07, cylinder
head tightening).
Refitting is the reverse of removal.
For refitting the timing belt, (see section 11-
Timing belt).
Fill and bleed the cooling circuit, (see section 19).
