TS250/1 swinging arm spindle removal

[rightsideup]

I know that they are notoriously difficult to remove but, after two weeks, I am at an impasse when it comes to the removal of my swinging arm spindle.

I've used endless WD40, hammers and using the spindle nut to pull the spindle (now stripped) - in total I'd say it's moved 15mm.

I'm at a loss what to try next?

I never had, or worked on a TS, but to frame the situation (click to enlarge):

I suppose inner bushes 1 (right, 54mm long) an/or 2 (left, L=44mm) are rusted onto the spindle 11. The swingarm has no bearings, it has a rubber bush (4 & 5) between the steel inner bushes and the swingarm. The construction is similar to that in the later ETZ, and should in principle be maintenance free. But in practice, if the rubbers are gone, you're up the brown river.
I once had a similar issue with an SP400 swingarm axle/spindle (because the previous owner failed to put decent grease on the axle at assembly), which eluded me for years. After many failed attempts with hammers (while supporting the opposite side with weight), copious amounts of WD40, and indeed a torch, in the end I managed to get it out by pulling. I used the thread on the shaft to pull the shaft, by putting ever longer bits of pipe below it. Sounds like you already tried something like that. If your thread has already been stripped, maybe you can try drilling a hole and tap thread into that? Pull, in combination with tapping from the other side, and WD40. Good luck!

WD40 is a water-displacing fluid/lubricant, and next to useless as an effective penetrant.
Get some PlusGas formula A, made specifically for this task.

By all means, try any product available, but I politely disagree on the qualities of WD40 sir. I think it's exactly aimed at something like this, and normally quite effective.

Only, the place it has to reach is quite deep, and difficult to get at. What might help is trying to get some help from air pressure, for instance by, after spraying penetrating oil, try to blow it in the creak with an high pressure air gun (spray - air - spray - air ...). Or maybe you can fit something over it, to build-up some pressure & force it in? Both sides.

I suppose inner bushes 1 (right, 54mm long) an/or 2 (left, L=44mm) are rusted onto the spindle 11.

Funnily enough these bushes aren't seized on the spindle - they move freely enough when I move the swinging arm up and down. It must be stuck in the frame?

[Puffs]

I suppose the reason for wanting to take it apart is that the rubber bushes 4 & 5 have perished? Or is there an issue with the engine mounts?

If the bushes 1 & 2 move freely when you move the swingarm up & down, then indeed, it's not stuck there - and that makes things even more difficult. Then indeed the spindle must be rusted onto the frame tube 10, and it gets even more difficult to reach with any penetrating oil. Still, that's the only thing I can suggest...
