swingarm help

[Spitfire]

You also have the option of a needle roller upgrade from Wemoto.  http://www.wemoto.com/bikes/honda/cb_750_f2_sohc/78/picture/swinging_arm_pivot_bearing_kit/

Now that is nice to know.

Hi all, Sorry to bring this back but tried tonight to remove the bushes, but I'm pretty certain their not bronze they are more like steel. I've a 1978 cb750f2 is this possible?
Thanks steve.

That's correct. The bushes in my F2 were steel as well. There's various ways of removing them on the internet using all kinds of special pullers. I cut through them with a hacksaw blade in a handle the collapsed them inwards and pulled them out. A real tedious job to do. Good luck with it.

Thanks for the reply Roy, how did you manage not to damage the collar in between the two bushes, and how long did it take you?

The bushes fitted to yours should really have stopped at the K6 model, with the F1&2 and Auto models fitted with the newer bushes that are way easier to get out. But like yours my F2 was fitted with the earlier type, I'm assuming they were a replacement by a previous owner.  If you order bushes from Silvers website they also send you the older type, hence my saying I think they were a refit.

I did do some slight damage to the centre piece in the swingarm but it does not affect the way it works. It took absolutely hours to cut through the bush enough to get it out. I carefully used a jigsaw to get the job going, then cut right through with a hacksaw blade. You cant get right through all along the entire length, but enough to loosen the bush. I then knocked it out with a long steel bar with a straight cut end. There's just enough showing of the bush to hit it.

Getting the pair out took an entire weekend with a lot of swearing etc. I also had a very sore hand afterwards. There are a few write ups ont tinternet about making special pullers and other ideas, I will be going down that route next time as my way was a really tedious hard slog.

Try sending a PM to BryanJ or Trigger, I'm sure they will know an easier way to do this.

Cheers Roy.

You should take everything out of the swing arm so, you are just left with the bushes. Used a good hacksaw blade and cut a line down the bush, cut another line about 5 to 10mm next to the first and the bush should fold on its self to get it out. Did post some pics for MR T on how to do this.

For new bushes get on to frank, link >>> http://www.ebay.co.uk/itm/Honda-CB-500-550-750-900-Four-Schwingenlager-Bronzebuchsen-Swingarm-Bushings-/360953538938

Did that work for the steel type bushes Graham as mine were a real bitch to get out. The bronze type I did later were really easy to do?

Thanks trigger, Roy, Julie

Already got the bushes from frank after reading the chat about this. I'm going to try a few methods and hopefully give help to others like I've had. Going to learn some new swear words for the attempt over the weekend.
Wish me luck l'm going in.

Julie's comment about the reciprocating saw is probably the big clue. Good luck and I hope you don't end up being called no thumbs. LOL.

LOL it was a motorcycle chain that took the other one.

Kids!! don't clean motorcycle chains with the engine running on a paddock stand while in first gear. Did it like that for years, only takes one mistake.

Still loved that ZX6R though

The first clue was right Roy, don't own a reciprocating saw
