Never ever hit flywheel to remove it.

Damage to the front thrust washer after lightly striking the rear counterweight with a breaker bar to help remove it (while using the puller). ONLY use a puller to remove the flywheel, any striking will damage the thrust surfaces.


I knew this allready but thought a few light taps wouldnt hurt,...

I have never ever had that problem. I've removed maybe 50? (don't know really). All with a rubber mallet.

My very first engine had the same markings from the needle bearings, and its not due to hitting the flywheel. Most likely those markings were made during while the engine was operational. I have removed a couple flywheels since then without a problem. Hitting from the side should not put a enough downward force to push the needle bearing in that much, most likely the endplay was off.

I was technically removing the counterweight but it's the same deal with the flywheel.


If you do hit the flywheel, at least inspect everything very closely, Thoose marks were invisible until i got all the oil of the thrust washer.

I have heard of this happening before when the flywheel is removed by striking it so It isn't just me.

Every other time I have just used the puller with no problems, but this time I got a little impatient and struck it a few times with the puller on to get it to break loose. Maybe the fact that I used a hard object and not a rubber mallet? Anyhow just a heads up, and i had never seen pictures of this type of damage posted, only heard stories.


btw there is no way this type damage could be caused while the engine is spinning, and endplay was perfect. They were competition thrust bearing too, I imagine the marks would be worse with the smaller roller contact of stock thrust bearings.

Counterweight would be different from flywheel. When you hit the flywheel, you generally hit towards the end, where you'd get more leverage to "pop" it free. Not so much with the counterweight!

Because of this, i've never hit a rear counterweight, just used a puller that I fabricated from a couple pieces of angle iron doubled-up. I've never had to give a flywheel more than two good whacks with the rubber-faced deadblow, either. (Sometimes they pop off while loosening the front pulley bolt!)

Must have pull apart 100 motors and never had a problem. Damage must occured when assembling the engine.

nice post.
I bet a lot of rebuilds suffer from that condition since people wouldnt take the time to inspec it cleaned of oil and if reused it could be the beginnings of failure... that would suck but it happens all the time.
