Swingarm bolt removal

Hi All,
I have scanned through all the threads on the above topic. I am seriously loosing the battle on removing the swingarm bolt (2010 Tenere660z). I can screw off the nut,I cannot even turn the bolt:-

1. I tried different mixtures to break the rust (transmission oil/Acetone)

2. Tried heat (just the bolt)

3. Tried freezing (just the bolt)

4. Hammered it on it while bike is on its side, at this stage I may have mushroomed the nut side of the bolt (screwed on the nut to be flush with the bolt end).


At this stage I am resigning to the situation of drilling it out. Any advise on this front. Appreciating any feedback on this as it is wrecking my head. As I planned a big trip for mid July


Thanks
Ger

It can be tight due to rust as you say. Put the nut back on and thread it nearly all the way home. Put the socket on/over the nut and then hit the socket. The socket will protect the nut and the nut will protect the threaded end of the axle.

Also, with the nut undone, try placing a socket on the other end and turning the axle/shaft as if you are tightening the head of the axle. Sometimes this can work when applying clockwise force for a fraction of a turn ( just a nudge ) to break the grip of the rust.

Hi mate

There's no easy solution to this. If non of the above doesn't work then you will need to do what I eventually had to do. It will take a steady hand with a small angle grinder and the thinnest cutting disk you can get to cut the long bolt between the swing arm and the engine mount. I recently had to do this as a last resort with my XTZ which broke the 4th gear dogs engaging the 3rd gear!

It was so solidly sized that a 20 ton press just managed to remove the sized piece from the swing arm bush. See attached photos. I bought a new bolt and nut in the end and have changed all of the bearings bushes and seals on the swing arm....

Good luck.

thanks guys, sorry for the delay.


At this stage went to an engineering company and they advised to press it out. They tried an air gun for removing tractor wheels with no joy. They are advising to press it out.



Had placed an order mid June for a replacement bolt and nut. The company I used did not come through on the order and had to re-place the order with another Yamaha dealer.



Have a trip arranged in Wales next week so I plan to go on the trip. Once back I have to strip the bike as much as possible to allow them press it out. Wondering should I cut the bolt to remove swingarm or just press the full bolt out, no amount of hammering is going to move the bolt I feel. Cheers Ger

Last resort time. Try a car jack.....put the nut back on so it has 3 or 4 turns on the shaft and then put on the matching socket on the nut. Now the tricky bit. ...place a car jack on its side and offer it up to the socket. Using load straps, tie / wrap the frame of the car jack to the frame of the bike. Use the jack to put pressure on the socket. Be careful and watch / listen for pressure stress. The jack may successfully force the axle spindle a couple of millimeters just to crack the rust. If it does then use the hammer on the socket or a drift bar.
