Removal
Remove the toothed belt for the main drive.
Unscrew bolt "1" and remove the tension roller of the toothed belt for the main drive. Check the position of "TDC" of the camshaft: the flattened tooth on the gear of the toothed belt "1" for the crankshaft should coincide with the mark "arrow" on the oil pump housing.
Turn the crankshaft slightly against the direction of engine rotation. To the right of the cut tooth "A" of the toothed belt gear, the 3rd tooth "arrow" should coincide with the mark on the oil pump housing. In this position of the crankshaft, one of the cams is at the top, which makes it easier to install the oil pump. Remove the oil pan.
Unscrew the "arrow" screws and remove the suction pipe.
Unscrew the bolt "arrow" and remove the running roller for the toothed belt of the main drive. Unscrew the bolt and remove the gear of the toothed belt for the crankshaft.
Unscrew bolts "1...5" and remove the oil pump housing.
Installation
One of the 4 cams "arrow" is on top of the crankshaft. Replace the seal and bolts for the oil pump housing.
Install the Allen screw from the sealing ring press tool "3083" with the mounting tool "T10022" onto the crankshaft and tighten by hand. Place the oil pump housing seal onto the centering bushings "A".
Install the oil pump rotor with the mark "arrow A" onto the installation mark "arrow B" on the oil pump housing. Lubricate the crankshaft cams with oil. Lightly lubricate the working edge of the oil pump seal with oil. Carefully install the oil pump on the crankshaft cam. If necessary, align the rotor relative to the cam, slightly turning the oil pump. Carefully push the oil pump housing onto the centering bushings. Installation is in the reverse order, in this case it is necessary to install the oil pan, tension roller and running roller for the toothed belt of the main drive.
