Nut Sert, Rear Tail Section Sub Frame
I remember this was a subject on I-BMW just before it shut down. A fellow bought a K1300S MS and was trying to put a luggage/tail rack on and found that the Nut Serts were spinning in the sub frame member. I did not remember it until it happened to me this morning and I knew this was not coming out without cutting somehow. Since it was a nice day here in the north east I made the 200 mile round trip to buy a spare screw...NO BMW DEALERSHIPS IN PITTSBURGH.....COME ON MOSITES OPEN THE NEW STORE ALREADY......really 200 miles to buy a screw and I couldn't take the bike because I have the wheels off to change the tires.
I'm now in the same boat, I remember he ended up buying a nut sert installation tool as I have just done. But removing the screw is giving me a bit of a problem. I was going to drill it out but its spinning and I can't see anyway to cut the top off the head without doing damage to the grab rail and I don't want that. A Dremell tool maybe and just grind it away. I thought about a nut splitter but you can't get it in there.
If you've had this problem let me know how you cut the screw off in that confined space without damaging any surrounding parts. I can punch the or drill the nut sert after the grab rail is removed. I'm not a rookie when it comes to these problems usually but this one I'm stuck on.
I thought I instead of deleting the thread I'd put my results out here for the next guy that has this problem. I'll follow up with a picture of the new nut sert when I get the new tool.
OK everyone I got the top of the screw cut off by removing as much of the rear body work as I could with the grab rail hanging with the rear tail light cowl. I took a hand held small hack saw and taped up the surrounding frame so not to get damaged. It took awhile but success, now the nut sert was still in there with the remainder of the screw. I tried to drill but still spinning. A center punch and a small ball peen hammer and two smacks and it was punched thru. Coat hanger and a magnet got it out of the sub frame.
I can never figure out why pictures turn sideways when uploading them.
