Last year I added crash sliders to my aging Honda CBR 600F (1998)
Recently whilst trying to remove the fairing for other work, I found the nut and bolt were "seized". Actually, by using a spanner at either end, the nut will turn on the bolt, but it never climbs the screw thread. It's as if there is no thread for the nut to purchase on. The nut just goes around and around forever. (The crash slider on the other side of the bike came off with no problem)
Access is very restricted. I did manage to get my hand behind the bolt with a small block of wood, in an attempt to push back on the bolt, trying to get the nut to purchase the thread. No avail.
At this point I am resigned to probably destroying the bolt in order to get the fairing off. (New bolts on order)
But even if I drill off the head of the bolt (accessible inside the slider) which would allow me to take the slider and fairing off, I still won't be able to slide the bolt out from the nut-end, because there isn't enough room in that space.
I need a way to get the nut off. How?
I have marked as correct Nick C's suggestion to use a nut splitter. This is an update of how it went when I tried that.
- First, I got a replacement nut & bolt, and a nut splitter.
- Fitting the splitter onto the nut was pretty fiddly.
- I used another tool through the hole of the spanner to get enough purchase to keep turning the splitter.
- Nut finally off!
- But the other half of the nut still persisted in clinging to the bolt
- Eventually both halves came off. I have posted a follow-up question to ask what happened to the thread of the bolt: Thread on bolt - what happened?
