To prevent injuries from shavings, wear protective goggles and protective clothing.

-- Remove the remainder of the sealant from the cylinder block, for example, using a rotating plastic brush.

CAUTION:

Make sure that no sealant residue enters the engine.

-- Clean the sealing surface of the cylinder block and crankshaft journals; they must be free of oil and grease.

NOTE:

The following steps must be followed so that the sealing lip of the sealing flange does not roll itself up when installing.

-- Widen the sealing lip of the new sealing flange seal as shown using the oil seal guide sleeve T03004.
