flywheel clockwise , Align the line immediately after the "T"
mark on the flywheel with the triangle mark on the box
body, install the flywheel limit tool, tighten the bolts with a
wind gun, and correct with a fixed torsion, and mark with
an oil-based pen. Torque: 75±7N.m (7.7±0.7 kgf.m, 55±5
lbf.ft).
After the fixed-torque correction of the flywheel bolt is
completed, turn counterclockwise to start the large tooth.
If the rotation is flexible, the assembly is qualified. If it can't
rotate or can rotate in both directions, the flywheel should
be removed and reassembled and the unidirectional device
should be checked. Pull the starting big tooth upwards, the
axial clearance is about 0.7mm (0.028in), it is qualified.

tightening by the air screw, tighten it with the air screw,
and finally correct it with a fixed torque wrench. Torque:
12±1.5 Nm (1.2±0.2 kgf.m, 9±1 lbf.ft) . And mark it with a
marker.
e. Remove the flywheel limit tool and put it back to its
original position.
f. Restore the disassembled engine parts.
g. Use the whole machine leak detection equipment to
