flywheel

Post by chimos2000 »

my flywheel has come loose. has anyone else ever had this happen to
them. I haven't opened up the housing, but i've removed the starter
and you can spin the flywheel with your hand.I'm goin to open up the
housing later today so I guess I'll know more then.

If I'm not mistaken, I don't think you want to lighten that flywheel
at all. It helps with dampening the vibration from the crank, which
will definitely add to the the life of the engine. The other factor
to consider is the weight of the spinning device. If you remove the
innards from the alternator after you install another type of
external alternator, the engine has less momentum and won't climb a
hill very well. From what I've been told (by Mike O'Connor, I think)
is that removing the weight from the crank, you end up with an engine
that builds RPM's much quicker, but won't maintain them very well
under heavier loads. I would have to imagine that a lighter flywheel
probably has the same effect, and would give the same results as
removing the alternator innards. Bill or anybody else wiser than me
might want to chime in on this subject, as I'm sure somebody knows
better than I do about this as I've never done it first hand, but I'm
pretty sure the effects would be more harmful than beneficial. I very
well could be wrong, though...

Yes,I saw some galling on both the crank and flywheels on some of my
motors. The long bolt that fastens the crank and or flywheel/pulley
setup must be torqued to specs and loctited . You can carefully
dress the crank taper with a fine file,and I would replace the
flywheel if galled badly. Then if you want it right,you can lap the
two together with valve grinding paste . riceburner006

Don't lighten the flywheel, the car won't go up hills, also when I
lightened mine, I had the whole winding removed, a 10 pound loss.
Revs fast, but no power.

The flywheel is mounted on a taper at the end of the crank, there is
no key way or spline, there is no right way up, no marks - it is
factory balanced. I wouln't bother dismantling the flywheel off the
engine, just tighten the flywheel again using a holder wrench 22mm on
the flats of the pulley and the 17mm on the bolt, squeeze the
wrenches together, careful not to drop the wrench on the live wire to
the battery.
In case you already took it off, use some 400 grit to clean the end
of crank & inside of flywheel. Inspect for burrs on the flywheel, the
crank is harder metal.
