Disassembly / Assembly Process
1. Remove the exhaust pipe and silencer.
2. If the recoil assembly does not require attention, the
r
ecoil rope can remain attached to the handle. If recoil
component work is desired, reference the Recoil
Assembly section.
3. Remove the two mag-side engine mounting bolts.
Car
efully lift the mag-side of the engine to access the
housing cover.
4. Remove the recoil/magneto housing cover. The recoil
assem
bly is located inside the housing.
5. Remove the recoil hub from the flywheel. Secure the
flywh
eel with a strap wrench, PN PU-45419. Remove
the flywheel nut and washer.
6. Using the flywheel puller tool, PN 28
71043, insert the
puller’s three screws into the flywheel.
NOTE: Do not thread the puller screws into the
mag
neto/stator located behind the flywheel.
7. Turn the puller center bolt in until the flywheel “pops”
off
of the crankshaft.
8. Mark the location of the magneto/stator plate in
sever
al places using a scribe.
9. Remove the two plastic rivets that prevent the trigger
coil wire
s from contacting the flywheel.
10. Remove the magneto/stator from the crankcase.
11. During assembly, route the trigger coil wires in
their
designated channels. Install the two plastic rivets into
the housing to prevent the wires from accidently
coming into contact with the flywheel.
12. Assembly is reverse of disassembly
. Reference the
fastener torque specifications at the beginning of the
chapter.
13. Do not use an impact wrench to install the flywheel
nu
t.
14. Align the mag-side engine mount with the two chassis
mo
unts. Install the engine mount screws and torque
