Found the same thing when I had my last rear tyre changed. On mine, the slot in the swingarm that the collar sits in was a little dented, above and below the edge of the collar's neck. I stared at it and stared at it, but can't work out how that happened without more damage being done. There is no freeplay in the rear wheel, nor damage to the axle, and the dings are only on the outside edge of the slot in the swingarm. They look like someone has inserted a lever into the slot with the wheel off and worked it up and down to a 45 degree angle. I can't see how the damage could have been caused with the bike on the road. All kinds of other damage would have had to have happened at the same time, to the swingarm itself as well, and there's no sign of anything. I filed the dings smooth, and it doesn't affect the seating of the collar (but looks like it caused the collar to crack in the first place).
Incidentally, when I went to my local Triumph dealer, they quoted me $205 to replace one collar - to which I (finally) laughed out loud, and just walked away. Picked up a set from Pinwall Cycles on ebay for $10.
