Lock the flywheel with lock 67.7820.9534 (see figure 35), unscrew the flywheel mounting bolts and remove it. Remove the old rear crankshaft oil seal from the holder. Lubricate the new oil seal with engine oil and, using conical mandrel 41.7853.4011 (figure 23) put it on the crankshaft flange. Mandrel 67.7853.9581 (figure 24) press the seal into the holder. The seal protrusion relative to the outer surface B (see figure 37) of the holder is not allowed, and the recession of the seal relative to the same surface should be no more than 0.25 mm.
Install the flywheel in place (by the mounting pin) in the same position as it was on the engine, i.e. so that the mark (hole) near the flywheel rim is opposite the axes of the crank journals. Having locked the flywheel with lock 67.7820. 9534, secure it with bolts, installing a washer under them.
Install and secure the clutch on the flywheel, positioning the driven disk with the protruding part of the hub towards the pressure plate and centering it relative to the flywheel with mandrel 67.7853.9597 (see figure 76). Install the gearbox (see section. "Transmission").
