Harmonic balancer

After splitting the crankcase for another issue, Im finally putting this thing back together. I noticed on the engine rebuild videos here that on the left balancer, the large peg is to go into the larger hole. The Clymer manual says the same thing. But on this forum the opposite is stated. Large pin = small hole. I need to know which it is. Also I understand the flywheel has a timing mark on it to line up with the balancer. Im trying to get this right but still a little confused. Any help is appreciated.

I only have the downloaded manual, it shows the largest hole remaining empty.

I believe you may have seen the post I made about mixing up the holes and shaking my bike to death. Largest pin of the damper weight, goes into the smaller hole of the damper gear.

Logically one might think, largest pin into largest hole, but that is incorrect.

Searched for my post with a pic of the balancer assembled incorrectly, but something has happened with my pic host and the pics aren't showing. Can't access the host either right now.

Large pin to smaller hole, large hole empty. Be sure to align paint stripe or dot mark on the shaft, and of course the marks on the gear/rotor.

Warning: Two pics below show the balancer gear and damper weight assembled incorrectly. In the pics, the large post is located in the largest hole, this is incorrect.

The pics were taken the second time I tilted the engine to reinstall the damper gear correctly. Didn't think to get pics of it done correctly, just wanted to get it over with.

Damper gear aligned incorrectly, large post in largest hole is incorrect:



Rotor and Gear marks aligned, but large post in large hole is incorrect:



Dot on damper weight aligns with paint stripe on damper shaft splines:

Thanks Gaz, and you're welcome jeff.

Would be interesting to see which videos you watched.

Also, it wouldn't be the first time a mistake was found in a repair manual. Clymer is usually better than that or was in the past, I've had the most trouble with Hayne's. Some of those were pretty huge blunders, found one in a Hayne's just the other day. Hayne's says to drop the fuel tank to change the fuel pump, when the last five years covered by that manual, have access panels in the trunk. They also mixed up valve specs between the 2.0L and 2.5L GM, entirely different specs between the two. Using those specs would result in the engines not running, or running like crap depending on which one you have.
