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,.....

Did you measure end play before that engine was taken apart?

The only time I have seen that in a motor is when I was setting turning the motor over w/ a socket and rachet to realine the CAS from being out, and I forgot to remove the rachet and socket before trying to start the vehicle. Boy I guarantee that will never happen agian. I triple check for tools before starting motors now. Nothing like doing work twice. After that I had amost the same look you have there. I threw away the spacer so I could forget that moment.

Ive banged off a bunch of flywheels with a hammer and have yet to see that happen.

Me too https://www.nopistons.com/forums/pub...IR#>/blink.gif Never seen that before? Im pretty carefull though, how hard were you hitting it?

I would suspect an endplay issue or perhaps the thrust warrrsher was put on backwards.



I normally smack the flywheel w/ a deadblow hammer around three quadrants to get it to "break free". No problems at all.

Just a reminder for those who havent heard it before. Make sure you put the flywheel nut partially back on, just not touching the flywheel before you bang it off. The last thing you want is someone losing a toe when the flywheel falls off the engine.

Sounds like a man speaking from experience above.

i have seen that befor, it happended when a customer had taken his front cover off with the moter still in the car, when he put the front cover back on the nedle bearings behind the spacer sliped down and got pinched when he re tq the front bolt.

Ditto!



I use a giant rubber hammer. Works like a charm.

I think this kind of boils down to one of those common sense things. When using a puller, the practice of placing the flywheel nut back on the crankshaft (albeit not tight) will keep the flywheel from flying off at warp speed once it breaks free from the puller tool. As far as using a hammer, I'm not too keen on that idea as I think it will dink up the metal, hence my use of a dead-blow hammer.

my 3 pound deadblow hammer is the king.

I've only seen dents like that in engines with improper end play.

I use a 15 lbs + log of firewood. Works like a charm each time. I learned it form Vosko.

That damage is called brinelling, as in Brinell hardness testing where a pointed tool is dimpled into the metal at a prescribed pressure and the depth indicating hardness. Use a puller instead.
