Re: Engine balancing question
Making the total rod weight end up the same, as well as the big ends and small ends all end up the same is a real long shot. If it were me I'd just have the shop balance the rods and spin the crank.

Re: Engine balancing question
total rod weight being the same - maybe.
big end weight being the same, too? not likely.
Both weights factor into the balance.
You already knew that, you were just distracted.

Happy new year to all the oso crew some things are correct and others are'nt what you need to do is recheck all the weights over your rod rotating rod reciprocating piston and pin rings brgs and assure yourself that the bob weight does not vary more than 10 grams less the bob weight can not be heavier then the original . If you have a larger difference than 10 grams less than the original I would recommender to rebalance the entire assembly not just the crank sometimes different weight affects different areas of the assembly more or less include your drive plate also if you have to rebalance.You might be able to check your bob weight yourself if your balance shop gave you a balance card with your weights you can compare them to your new weights and do the math if you need any help please feel free to call or email me anytime Sincerely Yours Laz Mesa P.S.

Re: Engine balancing question
M.B., that's why I recommended that the original balancing shop be asked if they still had the work sheet from the first balance job. It will have all the component weights on it to save some time and effort that would be spent verifying individual components. Just my two cents.

Amen to that... he is the best when it comes to balancing, he does it for many big time engine builders all over the nation.
