Balancing

In the balamcing of an internal balance engine I am assuming that the rotating assembly that is balanced is the crank, rods and pistons, and that the harmonic balancer and flywheel are balanced separately. The reason I ask is that I will install a Cloyes timing cover that states it MAY not work with an 8" GM balancer. That and surfacing the flywheel.

Re: Balancing

Well when I get mine balanced they have everyting from the flex plate to balancer, even the bolts washers are marked for their locations.
Saying that there is stuff all in the bolts washers, and flex plats , balancers are already indepenantly balanced....
you can get these checked indepantanly, on flex plates clutches presure plates, balancers you will se small 'drill' holes and maybe a counter weigght welded on.

this may refer to the timing marks on the cover may not match up to the marks on the balancer.

Re: Balancing

In your list of rotating parts, you should include the rings, rod bearing shells, and h/bal woodruff keys and bolts to attach items together.

As Steps suggested, sending flywheel and balancer along will make for a better balance.
If manual trans, send pressure plate also.

Re: Balancing

Thanks,I didn't give enough info. We are talking about an existing unit balanced years ago with not many miles on it (3-4k). I left off ring and such for a shorter post. The issue is with the 8" balancer maybe not working with the Cloyes cover. I really do not want to mess with my solid bottom end. If the only issue is the pointer I can deal with that. Otherwise I have never successfully attached a timing tape to the stock balancer so thought of a Fluiddamper, Rattler or other aftermarket balancer. As far as the flywheel I don't think that surfacing should really throw off any balance if done properly.

Re: Balancing

Scott,
If all you are doing is replacing the damper, you should not have an issue.

Re: Balancing

That was my thought since it should be neutral balanced like the flywheel. Just trying to notcreate a quagmire from a simple head cam intake change.

Re: Balancing

Sorry Steps, I have a problem reading Kiwi. I see your point about the bolts.
