Are you sure its not the wrong balancer? I would think even the aftermarket ones would have to be pressed on? I've never used them so I could be wrong tho...

 

the crank snout has been "worked". as in the pulley sanded it down a bit. so its just a hair smaller than it needs to be now.

 

Magnacharger sells a crank pinning kit.

 

yeah i know. i was just hoping someone had a used jig with bolt we could use. his wife is loosing her mind that he bought a under-drive pulley set for 225 and it didn't fix the issue. not a lot i can do about it, but try to help.

 

i ordered a crank pin kit from magnacharger as well. should be here soon

 

what did it cost ya?

 

This is an Interference Fit. The first time that thing spun off you were in trouble. It sounds like the crank snout was "sanded down" more than just a "bit". I sure wouldn't sand the crank snout and if I did it would be 600 grit or higher and I wouldn't put any elbow grease into it. The primary function of the bolt in not to keep the pulley from spinning on the crank snout(That's the job of the Interference Fit), but to keep it from Walking to New Orleans to quote Fats Domino. If you're FI you should have already been pinned. It appears there is no interference between the crank snout and the pulley hub at this point so the pin may be only a band aid sorry to say. There will probably be more bleeding down the road unless you get real lucky and if you do play the Powerball.

 

i'm not gonna sand it thats for sure. i was just thinking pin it 4 times and call it good untill it don't work any more. i understand how it works just trying to get my friend to understand it is hard sometimes. thats why he is in this mess.

 

I think basically to fix it the right way you need to replace the crank. Too much material has been removed from the snout of the crank, and even though you pin it, the pulley could still be wobbling and walking on the crank snout, eventually it will wear down too far and something will give.

 

i have a crank out there he can use but he will have to replace bearing and have it turned. he don't have the money for the at the moment. us navy guys have to save up
