Haven't gotten to that point yet.
Two kids, going two different directions, at two different times, a wife, a dog, a job, yada yada yada. So, I'm not to the point of hooking it back together yet.
I wasn't able to re-match the connectors on the first track I did. And the 3 1/2" distance is the key. Even if I was able to measure it somewhat close, the grease would make it inaccurate. Sooooo, I had to take the links back out, put them in a vise and spread them back out (flatten them out to remove the arch between the pins).
It would be impossible to remove the arch while on the pontoon, but it is possible to tighten them back up ('re-arch"?) on there. It's just going to take a lot of time adjusting that one track, but less than guessing where they should go. I'll put that one on the L/H front so I can watch it to make changes as pressure displaces the grease.
The other tracks are matched because I only worked on 10 crossbars at a time and put every part back exactly where it came from.
The track tensioners will adjust the alignment and how tight the chain is on the sprocket, but the only way to compensate for wear is to bend the links so the link pin rollers are seating correctly in the valleys of the sprocket.
Broken Grouser almost certainly has yours set. So if you do jump into the job (nightmare?) of pulling them apart, do it in small segments and keep everything in their respective locations!
