Slimline swinging arm spindle seized?

Leonard,

I had this problem with the spindle seizing into the Silentbloc bushes and ended up cutting the spindle and drilling to get the swinging arm out. I wouldn't use a big hammer and drift UNLESS you can support the frame adequately to prevent deforming the frame.

I remember that I had to replace the Silentbloc bushes during this overhaul, again not a simple job. If you're planning to powder coat the swinging arm you'll have to do this after removing the Silentbloc bushes, otherwise they can be affected by any heat during the coating process. The alternative is to spray the swinging arm if the existing bushes are OK to use.

I wish you luck with this.

I seem to remember people chucking the whole lot on a bonfire and burning the rubber out but this is probably not recommended......

when i did my siezed swing arm bolt i started by using a piece of flat metal drilled it out slightly bigger than the swing arm bolt. placed it over the bolt flat onto the gusset plate so limiting any damage to the frame grinder wise. i ground off the old bolt both sides then drilled out what was left to get the swing arm out .to removed the old bushes i just pressed the lot out from one side, then cleaned the tube out. i placed the new bushes and spacer together on the bolt and placed it side by side with the swing arm tube to gauge how much of the bushes would protrude out of the ends of the tube, took a measurement . i then pressed the first bush in using an inverted impact socket so it contacts the bush with a flat surface to keep it level if it hasnt it will mess up the end of the bush. i had to grind the centre of the socket slightly so it missed the central tube of the bush. i then press the bush in to the level noted earlier. turn swing arm over and place the spacer in and put the new bolt in just to keep the spacer central then pressed the other bush in again noteing the measurement taken earlier just to keep things central. in the past i have had bushes of all dimensions also ones that just push in which are no good. get a good set dont get the cheaper ones .

i gaffer taped aound the socket incase pieces of it launched its self my way. never get at eye level.

Guys, Stripping a 650SS frame for powder coating but can't get the swinging arm spindle out so I can seaprate the swinging arm from the frame. Is this common? Do I need to get a hydraulice press on this or can it usually be 'tappped' out with a big hammer (nuts on threads, of course!) ? I guess it has corroded into the silentbloc inner sleeves. Any thoughts welcomed. Cheers,

Hello I had a Honda with the same problem best ways are red diesel and soak it for a weekor more, or heat it up with a warming gun so this is a local engineeringjob or a good fabricatoror blacksmith if you have not got this equipment, where has I have the lot, To do these jobs, A 350lb anvil does come in handy now and then which I do have a longwith blacksmiths braiser and it tooling, if you can make it the east Yorkshire I will sort it for nothing just your fuel cost, of gettingit here,yours anna j
