Title: flywheel to crank
Post by: fryedaddy on March 22, 2021, 09:42:45 PM
ok heres a dumb question but im going to ask it anyway.when installing a fe flywheel are there any alignment marks or anything to go buy,or do you just keep rotating the flywheel till the holes line up?

i have been running a c6 since 1987,been a long time,i remember when it was a 4 speed in the early-mid 80s.seems like i had to rotate the flywheel till it lined up.cant wait to get it running with the 4 speed in it.its factory 4 speed so the changeover wont be too bad.

Small but time and muscle saving tip.  Before removing the flywheel take a paint or magic marker and draw a line between the bolts to the pilot bushing.  When the marks line up on reassembly you are good to go.

That is completely unnecessary.  The bolts are asymmetrical.  You can't possibly put the flywheel on miss-indexed, or backward for a plate.  It just won't work.  But, it's not like you spent any time marking anything so if it makes you feel good...  Not really all that much different that marking your heads left and right so you don't get them mixed up.

One bolt is offset.  It only installs one way.  You just keep rotating until they line up. 
Seems like it takes me about three rotations before I find the right way because I never believe I got it right on the first try.
Then I need to verify it.... ::)

The same designer that made USB ports made Ford flywheels.

Same. I like to pick it up the right way the first time.

LOL!!! Why is it that 99.9% of the time, you get it wrong on the first try? Not even Murphy's Law has odds like that. ;D

Technically speaking, it has to be that way for the external balance engines. You don't want the weight to end up in the wrong place.

It's like that for all engines that I am aware.  Not just external balance.  Put a 390 flywheel on a 390 and it's the same thing.

True, they only go on one way and you can eyeball it before you pick up the flywheel.  I mark FE flywheels (and others of equal or heavier weight) to make it easier to get it lined up right and fast when rolling back up under a truck with it on my chest.  I definitely do it with tractor flywheels...those are heavy sob’s...makes lining it up faster without having to spin and check...spin and check.  They only go on one way too.

Clean/Wire brush the crank flange for better flatness and ease of aligning the holes.

Why I use a Sharpie on disassembly LOL.  I've also used paint daubs.  Never hurts to save a minute here and there.

Yeah it seems to always be the last turn you try...

I'm glad to see that others have picked up on the marking of the flywheel to ease reassembly.  As stated without the marking or exceptional eyesight the chances of hitting the pattern the first time is a crap shoot.  Using a sharp edged ring gear to lift or even turn a heavy piece of steel more than once is at the bottom of the list of weight lifting.

I remember from my days in the Navy we used to say 50/50 90/10, 50/50 chance of getting it right 90/10 probability of getting it wrong.
