Hi,
I was cleaning up the threads on the 12 engine studs from my Z400J project.
2 of the studs have a straight line "groove" in the threads, at the bottom end that goes into the crankcase.
I assume this isn't normal?
Will they need replacing, or is it ignorable?
Thanks for any advice.

Re: Thread damage on stud - replace?
Looks like someone has put a saw cut across the threads to make them act as a thread cleaner or to true the threads in the alloy case.
Most likely the first 2 or 3 threads in the case were burred.
They are only on the threaded part and don't weaken the actual stud so i'd use them.

Re: Thread damage on stud - replace?
As long as the stud threads are not burred they should be fine to reuse.

That's good to know, thanks.
Also, ta to Zed1015 for the reason the marks are there- never knew of that.

That's very kind of you, if I get cold feet about using them I'll get back to you.
If you have other Z400J stuff do let me know- not too many owners out there!
