Afternoon all.
I've got a real doozy of a problem here. I need to service my swing arm bearings on my st660z and whilst I can undo the swing arm nut, and the bolt turns smoothly, the bolt just won't draw back through the frame. I've tried gentle persuasion but am completely out of ideas to get it out without whaling on it with a big hammer. The problem lies I feel that the bolt has worn and has a shoulder hitting up against the frame, swing arm or engine.
The swing arm has about 10mm lateral play and so the problem needs to get resolved.
If anyone can come up with a possible solution, I'd be forever grateful.
Thank you in advance.

Usually if the pivot bolt turns but it won't move along its axis it is down to the bolt having seized in one or more of the bearings' collars/bushes. In which case brute force and ignorance is the favoured option. It's been covered before. The thread below contains a useful selection of ideas and tricks for you to perhaps have a go with.

I'm afraid this is a fairly common problem on the Tenere, and the reason why early intervention is key. The official service interval of 30,000 miles for the swingarm pivot is a joke.

Thank you all for your advice and help. It was truly stuck and it took removing the tank, panniers and laying the beast on its side and persuading the bolt out with a sledge hammer and drift. I honestly thought I'd have to cut through the swing arm at one point, but after a n hour of whacking it came good. The next problem was removing the old bearings and bushes fro the swing arm. Again pulling, drifting didn't avail. So I paid for them to be spark eroded out by a local engineer (machining hardened steel is tough at the best of times). Curiously though the bushes I thought should be brass turned out to be fibre. I'm replacing with brass now and all bearings, bushes etc. What an absolute faff, but hopefullyvafter the parts arrive next week I'll be up and running again. My bad for not greesing the bearings often enough, but I can't help but think it's a bit of poor design.Lesson learnt. Thanks again to all who replied. I'd been truly stuck.otherwise.
