Loosen the car alternator. Push it inward and remove the V-belt.
Unscrew the protective shield of the control belt. A socket wrench is required to remove the socket screw.
Crank the engine until the first cylinder is at top dead center. When carrying out this operation, use the ignition timing marking.
Loosen the drive belt tensioner and remove the drive belt. Tighten the belt in a way that is convenient for you so that it cannot slip off the camshaft flywheel, but do not tie the belt, as it may bend. Now do not turn the engine over.
Holding the camshaft flywheel in a way that suits you (for example, by putting an old toothed belt on the flywheel), remove the flywheel screw. Remove screw and washer.
Using pliers, remove the segment key from the camshaft.
Screw the camshaft flywheel together with two washers as far as possible towards the end of the shaft.
Take the pull-out tool 2085 in your hands. Unscrew the inner section (A) for two turns (about 3 mm) from the outer section and lock in this position with the locking screw (IN).
Lubricate the threaded head of the tool, slide it onto the camshaft and oil seal ring while pressing the slip ratchet, and screw the tool into the oil seal ring.
Loosen knurled screw (IN) and screw in the inner section (A) towards the camshaft until the O-ring comes out.
Clamp the tool in a vise and use pliers to pull out the oil seal ring. Lubricate the sealing lip and outer surface of the new sealing ring with oil. To install a new oil seal ring, use a piece of pipe of a suitable diameter. The pipe must be completely pushed onto the outer perimeter of the O-ring. Bring the sealing ring without distortion and drive it in until it rests against the outer surface with a shoulder. Do not drive the o-ring all the way in, otherwise it may block the oil recirculation hole. It is also possible to insert the oil seal ring in the manner described for replacing the crankshaft front seal ring.
