REMOVAL - REFITTING SEALING RINGS : ENGINE

Leave the sealing ring on its fitting support in the event of handling, refit the ring on its support and leave the assembly for 30 minutes before refitting .

IMPERATIVE : there must be no marks on the surfaces of the sealing ring .

WARNING : if the lip is deformed, replace the sealing ring .

The sealing rings provide sealing on the crankshaft on the oil pump side and on the engine flywheel side, as well as at the end of the camshaft on the timing pinion side; they consist of a pre-formed teflon lip .

When 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 .
