I am installing a long block in my 2006 F150 after a timing system inspection turned into the crank having a ton of extra endplay. I am following FordTechMakuLoco videos basically step by step.

I am ready to reinstall the engine but I ran into this issue: He mentions having marks on the torque converter "for balance" to have it correctly aligned for reinstallation. The problem is, in the first video, he never mentions making these marks at all. So I never marked them. I just dismantled them and went from there. I have no marks.

The question is, is the torque converter some how balanced or matched to a certain point on the flex plate? I would guess since it's fluid filled it auto balances and there's not one "right" way to hook it up.

Is that correct? or is there a "right" way to connect it, and if so, how do I find that balance point?

Here's where he mentions the balance in the 2nd video:

 

Nope the converter is not balanced to the engine.
the 2 gotchas are to make sure the converter is engaged all the way back into the trans like it should be, and if the torque converter has a drain plug on the front then line it up with a corresponding hole in the flexplate during mate up.

 

Not balanced to the engine is right
The factory ones have a yellow or white dot indicating max point of out of round or imbalance
The marks are on both the converter and the flex plate
The factory uses the marks, you don't worry about them if replacing your converter or flex plate

 

ok this helps, I appreciate the answers. I see the white dots, and I'm reusing my flex plate and separator plate. I don't see a drain hole on the torque converter, but I'll check again. Going to test the hub locking system, clean up the interface and reinstall the engine this weekend. Getting kind of nervous I'll miss something or make it harder than it already is.
