2. Carefully check the surface of the shaft journal that contacts the seal for scratches, burrs and other defects that could cause the new seal to fail. Replace the damaged shaft.
3. Measure the standard seating depth of the old seal in the holder socket, then place the holder plate with its edges on a couple of wooden blocks of equal height and, using a suitable punch and hammer, knock the old seal out of its socket. Try not to damage the socket walls.
4. Wipe the holder thoroughly, then lubricate the outer edge of the new seal with clean engine oil. The seal must be seated in the socket strictly perpendicularly, so it is not recommended to tap it into the holder with a hammer.
5. If there is no access to a press, the gland can be inserted into the socket using a large vice with soft jaws. The holder with the gland should be clamped between two flat wooden blocks, ensuring an even distribution of the load over the entire area of the end surface of the gland. In extreme cases, it is permissible to use a hammer, but the tapping should be done through a flat wooden block. Do not rush, make sure that there is no distortion.
6. Before installing the holder assembly with the seal on the crankshaft journal, lubricate the seal lips with universal grease. The holder is mounted on the engine without a gasket - instead, a uniform cushion of anaerobic sealant 2 mm wide should be applied to its mating surface.
7. Press the holder tightly against the block, tighten the mounting bolts by hand, make sure the holder is installed correctly, then tighten the bolts to the required force.
