I had a flywheel on my engine when i sent it out to get rebuilt last year.. Turns out it was an 130 tooth flywheel on the engine and i need a 143 tooth flywheel for my 440 engine. Do i have to get the engine balanced to the flywheel or can i get one from brewers and just bolt it on? Thanks
 
If it is neutral balance, it could be a 2084645 tooth flywheel and the balance would be the same.
(There is NO such thing as a 2084645 tooth flywheel.)
 
Thank you. Also how do i tell if my crankshaft is cast or forged. Never knwe there was a difference until i was on brewers site. Want to make sure i order the right flywheel. I know the crank has a deep hole for the input shaft of the 4 speed transmisson if that makes a difference
 
Hi charger, the 130 tooth flywheel will work if you have the correct bell housing as well as the 143 with the correct bell housing. as far as the balancing goes, you will need to know the year group of the engine but a good way to tell is by the balancer, is it the thick one or the thin one. 440 source has a good informational page on these differences. the flywheels are either zero balanced for internally , or offset balanced for the external . Brewers performance page will tell you most of what you are looking for. good luck. also, you can use whatever flywheel/housing is easiest to source or put together as a set as long as the balance factor is matching. Its not that big of a deal to find what you need and I hope this helps you. John
 
You are trying to determine if your crank is cast or forged?
If the crank is not in the engine, you can look at the finish of the unmachined portions. Cast cranks are sorta rough like the outside of the engine block. Forged are smoother.
 
If balancing is required, you you balance the flywheel to the engine, not vice versa. If you have a forged crank, the flywheel should be neutral balanced, with possible exception of 6 pack motors. If you can see the crank, a cast crank has sharp edges on the counter weights, forged edges are rounded and the sides show the machining marks. If can't see the crank and you have the OEM damper, a cast crank will say "440 Cast" or something like that cast into the damper and have an obvious non-symetric face.
 
Forged will have a ring when you tap it with a hammer. The cast will not. Simple

But a cast crank will ring......but with a different tone. And once the crank is buttoned up in the engine, that ring test pretty much goes out the window.

I have the balancer that says steel. I just want to make sure this is accurate. Thanks guys.
 
Pulled the flywheel off and tapped the crank with a screwdriver and it definetly has a ring sound to it.
 
It is generally an accepted practice that if you have an engine balanced professionally, the flywheel and crank are balanced together. Mind you, you can purchase both already balanced. I assume in your case that balancing was not a request so was probably not performed. A stock fly wheel, of the right size, in your case is the ticket. No decent machine shop would attempt to completely balance an engine without the fly wheel and if they do, your in the wrong place unless you've purchase a neutral balanced replacement.
 
Thank you. I called up brewers today and ordered a neutral balanced 143 tooth flywheel for my application. Those guys are great people and very knowledgeable and helpful. Great service!!
