Dont head bolts work up to 3 times (assuming you measure the stretch of the bolt?)^^^ Unfortunately it's expensive to need to go back in after assembly.
Yes, it hasn't even run yet, but those are one time use parts - won't work right reused.
Eagle provided a chart (I have the sheets and paperwork provided) that have measurements that are required to be taken on the bolts using a set of calipers. it has a sheet provided to log the recorded lengths after each removal and provides a threshold that tells you when the bolt is not longer good. Is this not a TTY bolt?Eagle Rod Bolts are NOT TTY
