no matter what hp.Removing a flywheel is not that
difficult. There are various wheel pullers that can be
used.First the flywheel cap must
be removed from whatever type
engine you have.The most
common reason for flywheel rem
oval is to check flywheel key to
see if it is sheared.The crank sha
ft is tapered and so the flywheel
will be pretty much seized to it.
After removing the cap you will
see a nut and cup on todays engines, older models
will have a starter clutch,that can be removed with a
pipe wrench.After you remove the nut which will be a
three quarter or eleven sixteenth in size,you can
install a gear puller similiar to above to remove
flywheel, although you can remove by the shade tree
method which is a little risky
The shade tree method I use is to bind the flywheel
with a large scredriver in the fins of the flywheel and
remove the nut or starter clutch,if nut is removed
instead of clutch, I screw nut back down even with the
top of crankshaft, put a prize bar underneath flywheel
and strike nut with heavy rubber mallet while applying
pressure from pry bar and most of the time the
flywheel will pop up.Isaid most of the time, however I
HAVE HAD TO USE PULLER MANY TIMES ON
STUBBORN FLYWHEELS.
THE RISK using the shade tree method above is, that
if nut is not exactly flush with top of crank, you could
mess up the threads by striking it,thus not getting nut
back off or back on,so a sixteen to twenty dollar puller
versus a one hundred fifty dollar crank, you figure.
One more note; a flywheel with a sheared key is a little
harder to pull than one that is not since flywheel is
turned on crankshaft when it shears,thus causing
magnet to pass coil at the wrong time at compression
stroke, thus putting engine out of time,causing it not
to run.There is more on flywheel keys in archive
section of newsletter.
