So what you need to know is how many you get down to, before they are shot. I can't remember, Does a Loyd start with 186 links? A manual will tell you what the limit is. Repining your track is not a viable option (my opinion) I'd hate to be caning down the road, full noise, and lose a track. The first reaction (wrong reaction) would be to hit the brake. That could be catastrophic! I have seen track where the pin has pulled through the link (posted on here maybe 10 + years ago) Just imagine a Universal carrier being a cookie cutter......
On the positive side, new sprockets might tighten up the track a bit.
Ive just been out and put a vernier on U.C. hub with a new sprocket. There is 10mm from the root (bottom) of the sprocket down to the hub.
