Re: PICTURES AS REQUESTED #1
When the OLD top link is threaded to it's shortest length, the entire unit's end-to-end length is 17-3/4 inches.
Since my new link is in currently on the tractor attaching my rear blade, and I have to get ready for work soon /w3tcompact/icons/frown.gif, I don't have the immediate time to take a measurement on it. Maybe someone could fully retract the new top link and report a reading.
TresCrows; What is interesting: On the old style link, I cannot remove the threaded ends totally to compare shaft lengths (or at least it would take more force than I was willing to apply and risk destroying the unit). Since I couldn't remove them to see within the barrel, I assumed that there was a stop mechanism. Never hit me that maybe the two ends were colliding within the barrel. Sure enough, if I expand the non-nut end on the old link, I can fully retract the opposite end. Thanks for questioning and testing the conclusion. (That is the correct scientific process, which will bring us, hopefully, to the correct answer).
So, you are correct. My no-threads indicator is totally useless. It was just that I had happened to turn-in one particular end in first. It also tells me that if I can remove one of the shafts from the old link, and cut 36mm from the thread, I can convert my old spare into a new-style link.
