8. Cover the front oil seal in the front sealing flange with a clean cloth and apply a bead of D176 501A1 silicone sealant 2-3 mm in diameter to the flange, as indicated on the resist. illustrations.
7.8 Scheme for applying sealant to the front flange
Note: The flange must be installed within 5 minutes after applying the sealant.
9. Position the sealing flange (1 per resist. illustrations) with gland guide (2) on the crankshaft. Carefully slide the flange with the stuffing box through the guide sleeve and tighten its fastening bolts with a force of 10 Nm.
7.9 Fitting the front pulley with oil seal
10. Install the oil pan and crankshaft pulley. While holding the pulley from turning with tool T10172, tighten the new bolts of its fastening with a force of 60 Nm, and then tighten them by an angle of 180°.
