As title states. I'm sure it was like that before I tried to put the flywheel on but it doesn't matter now as I still have to fix it. Does anyone know where I can find a 12mm x 1.00 fine thread tap for the flywheel bolt holes on the crank? I also thougth about going to say 12mm x 1.25 and using my own bolt... would this be a bad idea?

 

How bad are they? IF they are stripped bad, you are in for a headache. You really do not want to change the pitch, it will most likely mess it up more.

Look into specialty hardware stores, I know Broward bolt does not sell anything that fine.

 

i don't think it's stripped bad. it's crossthreaded and i actually had a hard time getting the bolt OUT

 

are you going to use heli-coil if so they sell that size at auto zone and its pretty good stuff i have it on a motor mount 3 bolts stripped and i re threaded and used the heli coil

 

sweet. the motor is out the car chillin in my garage. i'll check it out.

 

that stuff is pretty expensive though the kit is like 60 bucks here where i live the the threads individualy, i think they come in a 10 pack there like 10 bucks its suppose to be stronger than before check it out let me know how it goes

thanks for the heads up. but to fix the crank $60 ain't nothin. better than having to rip the motor apart to put my other crank in it. thanks ill check it out and let you know.

that's the only way i'd try to fix it. Don't mess it up more.

 

kool

 

using a bigger bolt would upset the balance of the flywheel.

Like stated the helicoil is the best solution.


Also a good place to look for odd hardware/tools (like metric fine taps) is mcmaster-carr, http://www.mcmaster.com/ usually will be at your door step the next day or the day after.

Cheers.

 

btw can anyone confirm that 12m x 1.00 fine thread is the correct thread of the bolt?

actually read your thread wrong. i thought you were saying there was a helicoil kit for 12mm x 1.00. been looking around... still no luck on that size. only 12mm x 1.25 and 1.5 and 1.75

EDIT: nevermind... i read it wrong again.

 

try napa auto parts

 

damnit... can't find any heli-coil/perma-coil/thread repair kit with a 12mm x 1.00mm pitch ANYWHERE someone please help me out. I'd REALLY hate to have to pay to rebuild this motor (i have another LS crank) just because of this ****.

 

bump

are you sure it's M12 with 1mm pitch? I can't even find bolts in that size. Are you sure it's not 1.25mm pitch?

You might have to try to put a M12 1mm pitch helicoil and find a coresponding bolt that looks the exact same as your existing one. Kinda half-*** but it shouldn't overly affect that balance.

well from what i've seen people post on here that their helms manual states... yes. I took a bolt to a hardware store but I think the threads on the bolt I took was messed up. i'm going to check again though. I'd be ecstatic if it was a 1.25mm pitch.

 

Here is what my helms says...

 

It looks like Timesert doesn't have that size either. Not looking good...

 

update for anyone who was interested...

I found a local hardware supply shop that was able to order a 12mm x 1.0mm helicoil kit for me. it's ~$60 he said and should get here early next week
