II - REMOVAL - REFITTING OPERATIONS FOR THE
CON ROD BEARING SHELLS ON CYLINDERS
NO.3, 1 AND 4
aPerform the same removal - refitting operations as
for the con rod bearing shells on cylinder no. 2.
III - FINAL OPERATION
aparts always to be replaced: engine oil sump
seal
parts always to be replaced: Oil filter
parts always to be replaced: Drain plug seal on
engine oil sump
aUse a wooden spatula or an ABRASIVE PAD to
clean the joint face of the cylinder block and engine
oil sump.
aRefit the oil pump.
aFit without tightening the oil pump bolts, while keep-
ing a clearance of 3 mm to 5 mm.
aFit the engine oil sump seal.aApply SILICONE ADHESIVE SEALANT (see Vehi-
cle: Parts and consumables for the repair) :
-four beads with a diameter of 5 mm at (A) ,
-two drops with a diameter of 5 mm at (B) .
aFit the engine oil sump while supporting it using a
component jack. Note:
For removing and refitting the con rod bearing
shells on cylinders no. 1 and no. 4, position the
pistons at Bottom Dead Centre before performing
the same removal and refitting operations as for
the con rod bearing shells on cylinder no. 2.
WARNING
Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
WARNING
To ensure proper sealing, the gasket surfaces
must be clean, dry and not greasy (avoid any fin-
ger marks).
WARNING
Applying excess sealant could cause it to be
squeezed out when parts are tightened. A mix-
ture of sealant and fluid could damage certain
components (engine, radiator, etc.).
