2. Carefully prying with two screwdrivers or a large pry bar, remove the gear wheel from the shaft pin - try not to damage the oil pump housing.
3. If it is not possible to remove the wheel by prying, you will have to drill a couple of holes in its end surface, cut threads into them, and then use a bolt-type puller.
Attention! A drilled gear must be replaced!
4. Remove the inner belt guide - try to remember which side it was installed on the shaft trunnion outward, if necessary, mark accordingly.
5. Carefully prying with a small screwdriver, remove the old oil seal from its seat - try not to damage the shaft pin.
6. Before installing, lubricate the inner wall of the stuffing box with a thin layer of universal grease.
7. From a piece of pipe, a large flat washer and a long bolt, make a fixture for pressing a new stuffing box into the seat. The outer diameter of the pipe should be equal to or slightly less than the outer diameter of the stuffing box, with sharp edges chamfered. The bolt thread must be the same size as the crankshaft pulley bolt. The washer must be guaranteed to rest against the end surface of the mandrel and provide reliable support for the bolt head. Fill the stuffing box into the seat, then install the tool, screw the bolt into the end of the shaft pin, and, tightening it with a wrench, press in the stuffing box. As soon as the stuffing box rests against the bottom of the nest, tightening the bolt should be stopped.
8. Slide the inner timing belt guide onto the shaft trunnion (concave side out).
9. Make sure the key does not fall out of its groove in the trunnion.
10. Lightly lubricate the inside of the gear wheel with multipurpose grease and seat it on the shaft journal.
11. Install the remaining components in the reverse order of their dismantling. Refer to Section 7 for a description of how to adjust the timing belt tension. Make sure all fasteners are tightened to the correct torque.
