how to go about balancing your crank/rotating ass.

[no_doz]

ive been reading up on having your crank counterweights balanced to the weight of the rest of your rotating assembly (small end half of the rod-wrist pin bearing-wrist pin-piston-rings) in order to achieve a faster-smoother rev'ing engine & i have a few questions. with the 60* v6's there is 1 balancer per 2 pistons correct? also how do you go about weighing each side of the rod as well as each side of the crank so you can tell how much weight to add/remove to each counterweight?? also once you know how much your rotating weight/reciprocating weights are-for these engines would you add that weight for 2 cylinders up then the balancer needs to equal that weight or ? also if thats the way to do it which pistons need modified to match which weights? any help would be GREATLY appreciated!!

The balancer has nothing to do with it. Most people take the components into a shop and have the shop do the balancing. They have the proper tools and accurate equipment to do it properly.

good to know-i was reading http://www.carcraft.com/howto/ccrp_0...l_balance.html article & wasnt sure what to make of it & whether or not its something you can do yourself or if it NEEDS to be done by a shop-if i want it done ill just take it to a shop that has to tools/instruments needed-any idea of how much this usually costs?

Have a pro do it....its like using a book to operate on your mothers heart.....leave that kind of stuff to the professionals.........its the most ingrual part of your engine man......dont play with a crank..........do it right have a redneck machinist do it thats done it a thousand times.....my redneck is Dale and he is the ugliest most odd individual you have ever met......but........he has done cranks for John Force........nuff said.....just my 2 cents........do what you can afford but dont compromise on the botom end
I blew up cuz I cut corners and now I am doing it right........live learn and haul ass
