Hi, I have a Briggs & Stratton 18 HP Horizontally Opposed Twin Motor...

I need a flywheel for it... What all models (HP) will work on it.?

The motor is Model: 422707
Type 1501 01
Ckode: 89032312

Any help will be greatly appreciated...

P.S. will the aluminum flywheels work. Mine was currently cast iron

Thanks for your time... Hope you all had a great thanksgiving day.

You need to only go with the original flywheel designed and specified for your engine. Even if an aluminum one fit, I would think that the difference in weight of each flywheel could cause problems, maybe not, but possible. I would only go with the original. And it is not often that a flywheel needs replaced, why is the reason that you are replacing yours?

Hey, thanks for the reply... Mine was damaged during removal... Was frozen and could not be removed easily...
