Tecumseh snow king engine replace
Original Message   Mar 4, 2014 8:47 pm
I have a LH318SA(HMSK80) - 156574 - Snow King series - cast iron cylinder sleeve - recoil start - 3/4" Dia. x 2.37" keyed crankshaft - D/T 3/8-24 - has 18 watt alternator - Does anyone know an engine I can replace it with. I prefer a 10 hp or better with 12 volt dc or 120 volt ac start .

Yes,If I put my 8 hp flywheel on a 10 hp motor, It might be out of balance

I don't think that would be a concern. I've swapped flywheels, but only between identical engines.

But the flywheel should be balanced by itself (ie- spin it on just a simple shaft, and I'd expect you'd find it to be balanced). Likewise the internal balancing of the engine would be done using the crankshaft geometry, I'd expect. Asking the flywheel to help balance the piston going up/down would seem very strange to me. I think that would be done in the design of the crankshaft itself.

I also don't think it would make much difference anyhow. My current engine is a 10hp OHV Tecumseh. There are more powerful versions of it, which simply enlarge the bore, and would use larger pistons. I haven't compared manuals, but I'd be surprised if the flywheel had to be different, for the more powerful, larger-piston versions.

Someone please step in if I'm off-base here, of course. But I wouldn't expect problems with flywheel balance. They did at least check/confirm your flywheel would fit, etc, hopefully?

Flywheel balance would not be an issue.
A flywheel is balanced independently.
It doesn't matter what engine it goes on.
A balanced flywheel is a balanced flywheel.
Engine balance as was stated before
is controlled by the crankshaft.
Some engines (Honda's) also have balance shafts.
Which just smooth things out a little more.
