Need help to index 428 flywheel
I converted a 390 to a 428 with correct pistons/bore and a 428 1U crankshaft. I purchased a Centerforce steel 428 externally balanced flywheel but I don't know where to index the flywheel to the crankshaft. Help.:confused:

If I'm not mistaken, I think the 428 flywheel will only go on one way. If I remember right unless you have it in the right position, the holes in the flywheel are just a little off from the bolt holes in the crank. Try it, I could be wrong, it's been a while since I've had one of mine off.

The counter weight on the flywheel should line up with the counter weights on the crank.

During a clutch replacement recently, I decided to convert to a McLeod aluminum flywheel on my 427 stroker (428 crank). We noticed that the weight on the new flywheel didn't match the same position on the old, but bolted it up anyway.
Needless to say, the engine was way out of balance. I had the old one resurfaced, remounted, and everything was fine. It is very important to make sure the flywheel is properly indexed to the rest of the rotating assembly. I also realize an alternative would have been to "match balance" or index the new to the old flywheel, but decided to just stick with what had worked so well in the past. |
