You need to be more precise,
Do you mean mainsharf 3rdgear
Countershaft 3rd gear
Or selector

PLUS you dont move 3rd gear to be in third gear, the driving dogs are on a different gear

The 3 nubs on the gear are the "dogs"
the selector is called the "fork"
Thet "socket" gear is called countershaft gear.

It seems clear to me what he is after. As The dogs are what get rounded and cause problems

I know what the dogs are BUT the dogs that make 3rd gear work ARE NOTon 3rd gear and may well be on the countershaft gear not the mainshaft gear.
You need to sort out exactly which gear is damaged and locate it on the parts diagram.
I been doing these a long time and the bits you need are simply not that obvious, no matter what you feel like it should be called

No problem with pic you posted but you should note that in most cases of rounded dogs the gear with the holes needs replacing as well as the edges get sloped.
Gearbox problems were and are one of the most difficult to sort out.
We had an XS 1100 jumping 3rd gear under warantee with no visible signs of wear anywhere, yamaha said change everything, shafts, gears, shims selectors and drum. It took 6 months just to get the parts!

Yes I did, I see it is actually Steve so maybe I'm not out of luck. See my thread in 350/400  called 'what is this cog called'.
