I am about half way to my 50 hours so I was dinking around with my B2650, checking bolts and nuts and whatever. The little bolts that are on the FEL pivot points are 10 mm, there are 8 or 10 of them. These bolts were in different degrees of tightness. I realize they are not supposed to be super tight so that the FEL can operate but you would think they would be similar. I went ahead and put them to a couple of threads from touching, I think the nut has that nylon insert so that it will not slip. Anybody else notice this? Also the operators manual shows bolts that are not on my machine, I guess they do the manual for multiple platforms.
