The swingarm bush diameters are the same for the later "F" and "K" models from memory Mark, but they wore "hats" so sit proud of the arm a couple of mm instead of flush. Sorry about the "ribbing" mate, but you were getting a little carried away with yourself, ha ha! Cheers, Terry.

Terry;

In case you're interested, I have a dimension now on that "shoulder": it is 1.25" OD and it is .077" to .079" on the ones we have seen from Honda. If you go to .084" on the shoulder, the shaft is too short and the assembly won't stack up right on reassembly, making a very stiff pivot. So, we're making them match the ones we remove from the swingarm being rebuilt at the time, just to guarantee fits.

Thanks HM, I have to machine up a set (and probably trim my pivot tube) for the racer project before I go much further with it, (braced K0 frame with F2 swingarm to accommodate the F1 rear wheel with Borrani WM5 alloy rim, trick 5mm thk cast iron disc brake and Brembo caliper) so I'll use those dimensions.

Also, the F/F1 swingarms are different from the F2/F3 in that they have closed off axle slots, so no end caps like the K0-K8 and F2/F3. Cheers, Terry.

Well hopefully you can do a swingarm for a CB400F or are willing to include this bike also, i'm more then willing to pay a good penny to have it done right...

Just for S&G, All Balls Racing has a new section on their website..."Swing Arm Bearing & Seal Kits"...

http://www.allballsracing.com/bearing_and_seal_kits.htm

Unfortunately, there's nothing there but an error message...

I went there to see if there was a downloadable instruction sheet for my steering stem tapered bearing conversion kit...there isn't...

That's no problem, so long as I have the old one with bushings still inside. Then I can match up mounts and profiles.

I'm doing a set for a CL450 at the moment. It runs about $80, plus you pay the shipping. Some guys just ship it to me with $100 and I send back the leftovers (you can check with them, I'm good for it!).

Most guys so far have been getting a junkyard arm and start with my bushings and matched shaft, then 'pretty up' the whole thing, then swap them. Seems like a good idea, no down time and all. I have an extra "K" arm (like K0-K6) that I could do a "swap", like a "core" situation from an auto machine shop. It won't fit an "F" or later "K", like K7-K8, though.

Gabus has an extra "F" arm about now: he did this junkyard rebuild bit with me a month ago. Maybe you could buy his old one?

Hondaman, I'll get my ducks in a row and sometime around November I'll be hollering back. Thanks.

Hey Mark, I reckon it's time for you to go the whole hog, invest in a bead blasting cabinet and one of those Eastwood powder coaters and do a "Reconditioned Swingarm exchange service". That way someone can send you a crappy old junkyard swingarm, you can strip and powdercoat the arm to make it look like new, install the bushings and refurb the pivot tube, and all the recipient hast to do is bolt it back in? Geez, I think I might do that here in Oz! Cheers, Terry.

HondaMan.. timely post. Looks like I'll be sending you a swingarm soon. I have to get a salvage swingarm after I found my swingarm bolt was totally seized to the bushing
I pounded on that thing for hours with all sorts of solvents trying to loosen the thing. It was the very last bolt on the frame (figures) before I had the the bike completely stripped. Gave up and sawsall'd it off.. I don't think the po had ever put a drop of grease on the bolt.

Oh, man, that stinks. I've seen it before, though.

When I move into my next house (with BIG garage!), I'm gonna do something just like that!

Mark, I hope to be using your talents on 3-5 swingarms ( 2- CB550Ks, 2 or maybe 3- 450s) by the time it's all said and done. If things go right, I'll probably be contacting you around mid-winter about the first one. What about an old CB77 or CL72? Of course it'll all depend on how bad they are and how my funds go.
Later on, Bill

Yeah breeze,

That's what I've got in mind. I've just gotta get around and do just that. Kinda like to
keep the RD350 for kicks but, it may end up going too, if the price is right. Gotta get them out
and figure what to ask for them. They all need some amount of work, that's why I call them
"Project Bikes". Gotta fix the Hondas!! I've been trying to get around to doing just that, seems
like MY starter's broke. Ha!Ha!

Catch ya later on, Bill

HondaMan,

A few days ago I sent you a PM with a few questions about making up a set of bushings for my 550. I have the collar out of the bike and ready to head your way. Let me know the cost and the approximate lead time from when you receive the collar.

If you could, send me a PM and we can go over this in a little more detail.

Best Regards,

Ken

HondaMan,

Received your PM reply. Thanks. I will follow up with you via another PM.

Regards,

Ken

I need to replace my swing arm bushings. And since I was told the parts could take 3 weeks to get here I did not want to tear her down until I got the parts.

So when replacing the bushings on a 30-year-old bike do I just order the center collar along with the bushings and dust caps?

Oh and thanks for any suggestion and help,

Buck

Hi AR-Guy,

Besides the link provided by 71cb750 in the above posting, you could do a search for HondaMan here. Search through his postings. He has posted several articles on this. Just type in "swingarm bushing" , without the quote marks, into the Search box.

Besides, you might want to contact HondaMan by email (PM). When you find postings by him, go to his page here and then click on PM to contact him. Right now, he has a project going on where he is making swingarm bushings for members here. He is very, very good ( which frankly is a major under statement ).

AR-Guy · « **Reply #97 on:** September 22, 2006, 07:07:31 PM »

I had read the above link.

But was confused if I needed to just replace the pivot bushings or do/will I need to replace the center collar also. And quite honestly the more I read the more I was confused.

But I printed it so I digest it better!!

I do not think it is feasible for me to do this myself and I have a guy down the street that my local Honda dealer service manager sent to (they eat in my restaurant about 5 times a week so I trust them). And he said day I get the parts he can have it to me next day – probably cost me labor & breakfast!

Thanks for the advice.

Buck

ooppps almost forgot thy mentioned neddle berings also. pros and cons of brass vs. neddle....

Bodi · « **Reply #98 on:** September 23, 2006, 07:28:26 AM »

I would go with brass, although the brass/bronze ones I bought are too large - looser than the "repair" spec out of the package. Also the collar may be badly worn and is almost certainly unavailable from Honda.
So the answer - as is usual with 30+ year old bikes - is far from clear.
The needle bearing kit has mixed reviews. I've never used one, and if it uses the collar as a bearing surface you're back to the worn collar problem.
You won't know the condidtion of the collar until you disassemble it. If it has been properly greased for the last few decades it'll probably be OK.
The choice you haven't mentioned is the original composite bushings. These are not as bad as many here think, if your collar is OK I would recomment trying them. They're a bit tough to install as they tend to shatter but if you have a Honda mechanic to help you it should be no problem.

bryanj · « **Reply #99 on:** September 23, 2006, 07:58:46 AM »

You WILL need a centre collar, they are always worn, frequently more than the bushes. Personally i would order two new grease nipples as well BUT TAKE NOTE they are a push fit not a screw fit and must only be pushed on the shoulder not the end or they wont work!
