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.
DISASSEMBLING
(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.
ASSEMBLING
(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)
