hello, has someone removed the foot of a long telelens (400mm f2,8, 500mm, 600mm ) and replaced it with a replacement foot or for installing a lenscoat and was this a problem ??
It's a piece of cake, as John says just make sure you use the right size of key to avoid damaging the screw heads. I have replaced the Canon ones on both 500 and 600 lenses.

I've always replaced my original Canon lens "feet" with aftermarket ones from either Really Right Stuff or Kirk. The key, as others have said, is to use the correct Allen wrench, and to take your time doing it. There's no reason to use any Loctite or similar substance as I've found that the screws remain tight.
I would not use locktite or similar as you could have problems if you ever need to remove it.
I bought my first "Big White" (400 F2.8) back in 2009 and have yet to have one of these bolts loosen or to have seen it on other people's lenses.
