Casey Family Build Thread (coupe)

Thanks, Doug. I guess I'll start the begging process now to see if I can convince Mike to use the big scary power tool instead of me. I shrieked and whined the entire time I used the less scary one yesterday. I really didn't like it. Any suggestions if that (and heat) doesn't work?

Heat the bolt head with a oxygen acetylene torch and then hit it with the impact gun but be careful not to snap the bolt head off
Otherwise things will really suck from there the bolt is likely higher than grade 8 and pretty tough to drill out.
Complete engine disassembly will likely be needed to have a machine shop drill out the crank bolt and re tap it, hope it works out. If you can't get it out call the engine builder and ask for another method or help if he is local. Don't force it with a pipe.

I agree with HCP 65 COUPE that you should contact whoever assembled the harmonic balancer, aka crank pulley, to the snout of the crankshaft. Find out if they did, indeed, use Loctite, and if so, what kind (red or blue). Find out if they used a torque wrench or an impact wrench to tighten the bolt. And find out what torque value they used if they did use a torque wrench.

It's all good information to have... Some to help you get it apart; some to help you put it back together; and some to let you evaluate how sharp your engine builder really is.

All just my opinion. Hope it helps.
