Im posting this for a friend jasonp he recently had troubles with his act clutch which exploded and messed up his eagle crank his question now that everything is back together theres one bolt thread that is pretty much gone on the crank is it ok to run 7 flywheel bolts as compared to 8 thanks-pdang

 

I am sure it will hold but it will throw the balance off.

 

I would try to repair the threads in any way possible. If 7 were enough, Honda would have made it that way.

 

Heli-coil it.

 

I would fix it.

 

it should be pretty easy to tap new threads

 

we had to retap one on a 3sgte toyota motor. it worked fine and held up great. retap it just to be safe.

 

I wouldn't run it with 7 I would fix it.

 

thread insert it. don't just tap or spring it (heli coil).
As stated, if seven was enough honda would have done it

 

Dont use helicoils, they suck, use a timesert insert, they are great. do you think it could be fixed by just using a bottoming tap?

 

ok. I will fix it but where do I get a timesert insert from and how do I fix it.
