swing arm removal

do you have a new or old bike , does the swing arm move freely ???.

water gets into that area and can cause corrosion , if that area has not been
cleaned and greased in the past it can seize up .

use wd 40 or similar and try to get it into the gap between the engine and swing arm . flood that area and at the same time move the swing arm up and down to penetrate it .

If you've gotten the "regular" bolt off then that's all you need as far as the pivot is concerned. Besides WD-40 I also loosen the engine mount bolts when I take my swingarm off/on.

I had a problem removing swingarm pin as well. I kept putting off greasing the swingarm and after 100h or more it was stuck. I tried everything,in the end I stripped the bike down and had to take it to a engineering shop , layed the bike on its side and placed it in a heavy press to remove the shaft , the pressure from the press distorted the end of the pin, which had to be replaced anyway.

As the manuals state , grease every 15-20 hrs I think.....

the secret isn't so much 'what you hit it with' but rather 'what holds the bike firm'!

try to put something really solid against the fram right next to the pin. on the later model when i had this problem, i put a large tube over the bolt head and placed it against a steel plate that was against the corner of the house!

that means that when i hit the pin it took the full force and the frame didn't budge.

the bolt is indeed seized and it depends where. With bergs you are luckier than some other bikes because there are nuts on the shaft at iether end. Use lots of crc and a heat gun to warm things up. The hammer with the bike firmly placed on the side can work but be very careful you may have to put a new centre gasket seal and so on. Now remember with the berg axle you can take both nuts off and therefore can put a small tube over the bolt to the frame and then use the nut to wind the thing out using a pipe for leverage over the wrench. This all depends on getting a small tube of metal over the bolt and sill being able to get the nut on. In the end you may find your bearings did not need greasing, but that is besides the point. When you get it out before putting it back put that silver anti freeze grease on it so next time........

PS: you will need some help from your mates: do not open the beer till the job is done!!!!

Twitch,
not sure if you got it out yet but during this past weekend's ride I was talking to the mechanic from Euro Motors about that very problem. He had recenty had to cut the bolt because it could not be knocked out and a press could damage the case depending on how it is seized in. They said it was not an easy task still but it got it out. It is a older 470 that had never been checked so he was warning me to check mine periodically and grease it often, especially after several wet rides. I have yet to do that this week but I will soon and I am considering a zerk option if it looks needed.

had to deal with a seized pin recently but had managed to get both nuts off.

they tend to seized on the bearings in the swing arm rather than where it passes thru the rear of the motor.

the way i got it out was to heat up the swing arm as much as i dared then throw a bucket of water over it and use brute force to hammer the pin thru. (keep the nut on the side your hammering to start as it prevents the spindle from tuliping out, though it does wreck the nut) got it about half way out then with the bike layed over so the the side with the spindle sticking out is down i plugged the spindle and filled everything wil oil and left to soak for several hrs.

came back greased up the exposed spindle and knocked it back thru and out the other side.

it is rather frightening how hard you might actually have to hit it if it is really stuck.

the above worked for me and when i replaced everything i got the new spindle that only has a nut on 1 end.

A liberal amount of 'boat trailer wheel bearing grease' (water proof aluminum based grease) in the hole through the engine, on the shaft, and in the swing arm bearings will prevent this from happening ever again!
