Tried using a puller, broke the hardened bolts that came with it, i dunno what it is about this balancer but it went on so tight and now it isnt budging, is there any other tool i can use to remove it?

When you took the bolt out of the balancer did you also remove the large washer? If not then that is probably what is keeping it from coming off.

You may need to heat the part of the balancer that goes around the crank snout.

I agree, make sure you take out the big washer. Been there, done that.

Good luck.

As mentioned, the crank bolt has to be removed all the way out and then the washer removed. Screw in the bolt about halfway in the crank threads and 're-do' the balancer removal process.

When you put on the balancer, you lined it up with the crank keyway right?

How did you acheive the 345 stroker? Is that a 3.400" stroke with a 4.020" piston? Or a typo?

Good Luck!

Good Luck!

Is the 3.33" stroke crank custom or from a factory car?

Click to expand...

its a custom Bryant crank, i didnt build the motor i bought it used and it had been sitting for a few months after being freshened up out of the machine shop. The motor is great but i have just been having the most rediculous problems with it for the last 3 months. just really frustrating and summer is almost over so im thinking about letting it sit for the winter and think about what its done
