WarningObserve the safety and cleanliness recommendations
NoteThe sealing rings provide the seal on the crankshaft on the oil pump side and on the flywheel side, as well as on the end of the camshaft on the timing pinion side; the sealing rings consist of a preformed Teflon lip
NoteWhen the engine is started, the oil pressure exerts a force on the lip which makes contact leaving a film of oil on the shaft thus creating sealing
WarningCheck the absence of any mark on the bearings of the sealing ring
WarningIf the lip is deformed, replace the sealing ring
NoteThe seal must remain on its support during fitting; if handling, put the ring back on its support and leave the assembly in position for 30 minutes before refitting
