(1) Before removing Ignition coil, separate Cylinder cover
from Engine, and pull out Primary wire from Ignition coil
in advance. (Fig. 47)
(2) Remove two M4x20 Hex socket head bolts and Ignition coil
from Engine. (Fig. 47)
Note: Be careful to the torque to loosen the bolts because
adhesive is applied on the threads under our quality
control.
Once removing their bolts, do not fail to apply adhesive
to the threads.
(1) Insert 0.3mm leaf of 1R366 between Ignition coil and
the magnet of Flywheel. (Fig. 48)
Ignition coil will be attracted to the magnet through 1R366.
Then, without removing 1R366, fasten Ignition coil to
Engine with two M4x20 Socket head bolts. (Fig. 47)
(2) Remove 1R366. Then make sure that Flywheel does not
touch Ignition coil by turning it by hand.

M8 Collared
Hex nut
(1) Turn M8 Collared Hex nut in the center of Flywheel counterclockwise
using a cordless impact driver. (Fig. 49)
(2) Mount 1R364 on Flywheel, then screw two M5 bolts of 1R364 into
Flywheel as drawn in Fig. 50.
Flywheel can now be removed from Crankshaft complete by turning
the center bolt of 1R364 clockwise using a screwdriver or the like.
Important: Screw two M5 bolts evenly.
(1) Wipe off grease and oil from Crankshaft complete.
(2) Aligning the key way of Crankshaft complete with Woodruff key 3 on
Flywheel, install Flywheel onto Crankshaft complete. (Fig. 51)
(3) Screw M8 Collared Hex nut to Crankshaft complete by turning it clockwise
by hand.
(4) Tighten M8 Collared Hex nut firmly using an impact driver.
Warning: Remove Spark plug cap from Spark plug to prevent accidental
engine starting.
Note: Flywheel can be easily removed with a cordless impact driver without
using any locking tool, because Piston is locked in a position due to
the compressed air resistance in Cylinder.
Therefore, do not remove Spark plug, or the air in Cylinder cannot be
compressed.
