• Magneto rotor
7. Disassembly and reassembly of the magneto rotor
[Tools required]
• Jig J-363 (Code No. 6694822) (8 x 120 handle)
• Jig J-357 (Code No. 6695737) (Center bolt)
• Jig J-356 (Code No. 6695736) (Rotor extractor comp.)
• Jig J-365 (Code No. 6695739) (Shoulder bolt 5 mm)
• Socket wrenches (10 mm and 13 mm)
• Hook spanner wrench (for
ĭ
120 to 130)
(1) Disassembly
• Remove the two Step Bolts [19] by using a socket wrench
(10 mm). Remove the two Shims [18] , two Starter Pawls
[17] , two Starter Pawl Springs [15] , and two Washers 0.8
[16] .
• Remove the Flange Nut M8 [20] by using a socket wrench
(13 mm).
• Put the thread end of the Crank Shaft [1] and the top
surface of a commercial M8 nut at the same level, and turn
the jig J-363 (8 x 120 handle) in the arrow direction to tighten the jig J-357 (center bolt). You can now
remove the Magneto Rotor [14] .
(2) Reassembly
Reassembly can be conducted by reversing the disassembly procedure. However, special attention
should be given to the following items.
• Degrease the tapered portion of the Magneto Rotor [14] and the threaded and tapered portions of the
Crank Shaft [1] before mounting the Magneto Rotor [14] .
• Adjust the gap between the Magneto Rotor [14] and Ignition Coil Ass'y [23] when either is
disassembled according to “8. Adjustment of gap between the magneto rotor and ignition coil ass'y.”
• Turn the Magneto Rotor [14] clockwise around the Crank Shaft [1] for reassembly.
• Check the operation of the Starter Pawls [17] after reassembly.
• Lock the rotational movement of the Magneto Rotor [14] and then tighten Flange Nut M8 [20] at a
specified torque by using the hook spanner wrench (for
ĭ
120 to 130).
NOTE: • Hook the hook spanner wrench (for
ĭ
120 to 130) to the magnetic steel or counterweight
portion of the Magneto Rotor [14] for use.
• Retighten the Flange Nut M8 [20] of the Magneto Rotor [14] after mounting the Clutch
[36] to prevent loosening.
