Installation:
a. Align the keyway of the flywheel with the half-circle key and install the flywheel in place, put in φ10.3×φ28×4 washer,
M10×1.25×45 hexagon flange bolts, screw in the threads manually, tighten the timing chain, and turn the 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.
b. Tighten the timing chain, check again and align the line immediately after the "T" mark on the flywheel with the triangle
mark on the box.
c. Rotate the camshaft to align the dots with the camshaft pressing plate bolts, insert the timing driven sprocket into the
timing chain and assemble it on the camshaft, and at the same time, the timing of the timing driven sprocket is aligned with the
timing of the cylinder head Degree mark.
d. Apply thread glue to the M6×16 bolts. After pre-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 detect whether there is a leak.
h. Reinstall the rear shock absorber of the engine rear wheel back on the motorcycle.
