5.3 Resemble the crankshaft main bearing cap,
crankshaft, crankshaft bearing bushing and the crankshaft
axial thrust plate, pay attention to the following:
5.3.1 Assembling the bearing bushing, its raised thrust
block should fit into the locating groove in the cylinder
body.
Notice: The bearing bushing is from the same
manufacturer.
5.3.2 Spread the crankshaft bearing bushing (upper
piece) with oil before assemble the crankshaft
5.3.3 Mount the thrust plate on the cylinder body bearing
base and make sure that the side with oil gloove
(crankshaft shank) face outwards.
Notice: Spread the side of oil glove with oil
5.3.4 Fix the crankshaft bearing bushing (lower piece) in
the bearing cap, the bearing bushing should fit into the
thrust groove.
5.3.5 Spread engine oil over the friction surface of
crankshaft bearing bushing (lower piece), assemble the
bushing according to the mark forwards in the main
bearing cap of the crankshaft.
5.3.6 Spread oil over the bolts, within three or two times,
tighten them with specified torque.
Torque: 70±3.5N.m
5.3.7 Rotate the crankshaft after assembly, it should
rotates swiftly, the rotating torque should be less than
