Loosen the fastener "arrow" and remove the sound insulation "1" of the oil pan.
Unscrew the bolts "arrows" of the oil pan/gearbox fastening. Loosen bolts -1...18- crosswise and unscrew. Carefully detach the oil pan from the sealant layer.
Note: The parts of a vehicle with a 02Q manual transmission are shown as an example.
Installation
Installation in reverse order.
Caution! Risk of contamination of the lubrication system and bearing. Open parts of the engine must be covered.
Remove any remaining sealant from the mating surfaces of the cylinder block and oil pan using a chemical sealant remover. Degrease the mating surfaces.
Note: The sealant must not be expired (see expiration date).
Cut off the tip of the tube of sealant along the front mark (hole diameter about 2...3 mm).
Caution! Excess sealant may clog the lubrication system. The sealant layer thickness must not exceed the prescribed one.
If the crankshaft cover on the pulley side has not been replaced
Note: After removing the silicone gasket, a ledge of about 1 mm appears at the bottom of the crankshaft cover on the pulley side, which must be compensated for with a layer of sealant applied to the appropriate place on the oil pan.
Apply a bead of sealant to the cleaned mating surface of the oil pan as shown in the figure. On the mating surface of the crankshaft cover on the pulley side - between the arrows -; 3...4 mm. On the mating surface of the cylinder block and crankshaft cover on the gearbox side: 2...3 mm. In the area of the crankshaft cover on the pulley side, the strip of sealant should compensate for the now missing silicone gasket in height and width.
Note: The oil pan must be installed within 5 minutes after applying the sealant.
If the crankshaft cover on the pulley side has been replaced
Apply a bead of sealant to the cleaned mating surface of the oil pan as shown in the figure. Thickness of the sealant bead: 2...3 mm.
Note: Apply sealant especially carefully near the crankshaft cover. The oil pan must be installed within 5 minutes after applying the sealant.
Continuation for both cases
Insert the damper. Install the oil pan and tighten the mounting bolts. The oil pan should fit tightly against the adapter plate/flange of the gearbox.
Note: With the engine removed, install the oil pan so that it is flush with the cylinder block on the flywheel side. After installing the oil pan, wait approximately 30 minutes for the sealant to dry. Only then can you fill the engine with oil.
Fill the engine with oil and check its level.
