Pulling harmonic balancer

[Deca]

Hey folks- seems my harmonic balancer is really stuck..after removal of bolt and washer I tried using a 3-claw puller with rods that go into the crank- guess what, the rods bent..luckily didnt strip threads..

the workshop manual shows to re-insert the balancer bolt, leave a few threads out and use the puller on the bolt head. I’m afraid that under pressure the threads give in and the bolt slides into the crank, ruining the threads- or isnt that possible? See pic for bent rods.

thanks!

The crankshaft threads are pretty hard, maybe try getting a longer balancer bolt (no washer), and threading it in all the way (using all the threads) and trying that.

Yeah that would scare me as well, but as mentioned in the post above me give that a shot. If you bottom a bolt all the way into the snout, the threads won’t be bearing all the load, and it should start moving

Is that tool covered under warranty by Mishimoto? I’d call and inquire….

Have you tried to slightly heat the center of the balancer and then do the extraction?

Not a VooDoo, but this thread may help (tech/pics/vids within):

Go to Fastenal and get a stick of M12 x 1.5 threaded rod. Then you can cut a longer piece that will engage all of the threads in the crank, and have the puller press on the end. You can also use the remaining piece to make an installer

I tried every 3 prong puller? They did not work.
Believe it or not, Zander got a puller and

I used Zander method and worked like a charm. Grade 8 bolts and washers. He has you tube video.

Thanks guys- ended up making a 6 inch 8.8 fine metric M12 1.5 threaded rod to push off against. It screws/seats fully in the crankshaft so that gives the most comfort. Thanks for the help! Onto the next step.
