Removing
1. Remove the crankshaft pulley and its key (see "Crankshaft toothed pulley - removal, installation, replacement").
Warning. When removing the oil seal, do not scratch the working surface of the crankshaft.
2. Prying off the front crankshaft oil seal with thin curved pliers, remove it from the seat.
Installation
1. We apply clean engine oil to the working edge of the new oil seal and press it through a mandrel or a piece of pipe of a suitable diameter so that the outer edge of the oil seal is flush with the edge of its seat.
2. We install the crankshaft toothed pulley on the car in the reverse order of disassembly (see "Crankshaft toothed pulley - removal, installation, replacement").
3. We install on the car all the removed parts in the reverse order of removal.
