My '02 FE400 needs rebuild.However,I can't managed to remove the swingarm shaft. it is badly stuck in its place.a couple of blows with a hammer dd not work. I also tried to pull it off by screwing the nut on one end and by using a suitable spacer between the frame and the nut but tightening the nut sufficiently yields no pull.Any advice will be greatly appreciated.
It may just be jammed up from thing being out of alignment. I had this problem with my '04 YZ250F, so I just loosened the engine mounts and it came right out.
Unfortunately the corrosion gets to them and freezes them into them cases. My 501 at 6 months old required a setting it up against a wall with some heavy pipe over the frame and a sledge hammer to remove. Others have layed the bike over in a large press. Heat cycles and penetrating oil can help. Bugger of a job. Do a search on this site and you'll get some more info.

like steve, i put a tube against the wall and just over the shaft then around the other end hit the crap out of it. every little thing helps: heat penetrating fluids, loosening the engine.
fact is that the two bushes rust to the pin.
you'll also find this happens to the front engine mounting spacer on it's bolt.
where are you from then faust? and please put this and your bike in your signature.

this can be a nightmare. and as steve says normally on a berg its down to corrosion and gunk jamming everything up.
i ended up using brute force and heating/cooling to get it half way out.
then left the bike over night lying on its side with the shaft that the swing arm spindle goes thru filled with oil.
then next day a couple of big whacks and out it popped.
though i did have to get a new spindle and nut and it was rather scarey how hard i had to hit it.
think mine was a worse case senario one though.

Thanks for the help.Actually I bought this bike a month ago and the previous owner was a complete jerk.he told me that except visually minor wears on the bike, the motor is in good condition.After some time I decided that the motor has some issues and began stripping.I removed the left cover and the scene is not good.oil pump has been stuck due to shavings and thus plastic pump driver gear was worn.clutch outer gear wheel needle bearing has missing two needles.one of the bolts of the kickstart engament sledge was cracked and other is missing.After removal of the head cover, I found that the pins of the rocker arms were worn at the bottom where cam lobes press.There had been a surgery before on the rockerarms.Pins had been replaced and welded to the rocker arm on both sides.after I ground off the welding and removed the pin out of the rockerarm I even found that one of the needles were missing.I made a pair of new pins on lathe and also put the missing needle.But cam shaft bearings were also gone. I think there may exist more problems inside the crackcase.Maybe other bearings might have been gone too. Thus I want to disassemble inspect and rebuild the motor.I wish valves,piston,cylinder etc has more life. What do you think?Should I completely disassemble the motor?Or just wash the crankcase,replace worn parts, do some minor hand work, assemble the mess and ride it?

i'd replace the shagged stuff and just put it behind you. you sound a competent mechanic so you should be able to do it cheaper.
replace the intermediate shaft inner and the balancer bearing for sure. the list of just a bit more, just a bit more is endless. look for tuliped valves as well. change to a later decomp and tensioner blade.

And at the risk of stating the obvious, when drifting out a shaft, initially have the nut in line with the end of the shaft. You may only have a mm or 2 of space behind the nut but this will be enough to get it started and will minimise damage to the threads, including 'ballooning' of the end of the shaft. If you can use a brass or aluminum block/hammer it'll also reduce the damage. The trick is to support the frame so that all the impact goes into the shaft and the bike doesn't bounce around absorbing the energy of the blow.
