OTT Track Bolt Wear

[RodNH]

I recently had the opportunity to pick up a used set of Grouser OTT steel bar tracks for my S650. They do not appear to be worn excessively and the price was pretty good compared with new. While having to adjust the length to properly fit the shorter wheelbase on the 650, I had to relocate a number bolts on each track. As I have no past experience with tracks, I have no idea what is considered excessive wear on the bolts and bushings and what is not. I can replace all the bolts and bushings but do not want to do that if it's not really needed at this time. My use of the tracks will be fairly light, intermittent duty in woods around my own property. I am concerned, however, about possibly breaking one or more bolts out in the woods caused by bolt wear. Below is a picture showing typical wear of the bolts that were relocated. I would like any opinion if this wear is considered bad enough to consider replacement with new before using the tracks. I almost don't think so but thought I would ask those who have experience with such tracks.

That looks the result of running in sandy conditions. I would say that is normal if it is excessively gritty.
