Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Fork stanchion rechroming

Post by rob75 on Sat 17 Sep - 10:32

Hi all,

This week I brought my fork stanchions to a company that wel put new chrome on them. The forks kept leaking, so I assume it is the finish of the stanchions.

When disassembling the right one, the little bush got stuck on the rubber/plastic piece that is on the underside of the stanchion. After getting the bush out, a piece of rubber along with a spring came out.
My question is, what is this piece at the bottom and is it vital for the fork?

Regards,
Rob

Which bit? 9, 10, 4, 8 maybe?

P.S. They're all important. Having slightly messed up forks is a bad idea when you're going round corners.

P.P.S. How much is stanchion re-chroming? I replaced mine with new ones from a local machine shop. They're great, but weren't cheap.

The part is not in the exploded view. It sits on the bottom inside of the stanchion.

Rechroming is €80 each (done without a receipt ;-)) and eventually €15 extra if they need extensive straightening.

Thanks for your reply.

Got the stanchions back today. They needed straightening. One was 0.6 mm out of true and the other one 0.8 mm. The new layer of chrome is used to get them back to the original spec.
It seems both stanchions were really worn, apart from the roughness, so the leakage was evident.

Still I hope someone can help me out: it seems some kind of oil seal came (forcefully) out of the stanchion. Is this part replaceable? Is it necessary? And if yes/no, where to find info?

Kind regards,
Rob

The stanchions are back and as new. According to the technician they are better than new as the layer of chrome is thicker.

I took two pictures of the inside of both tubes showing the seal. One is missing.






Might anybody know if these are replaceable of can be left out, please let me know.

Cheers,
Rob

I had them rechromed at "De Wever" in Assendelft. Their site: www.hardchroomwever.nl

To me it seems a good company and according to some people I spoke they deliver good quality.

Leaves me with my question on the seal? Anybody any idea?

To my knowledge the only rubber seal on cb500 forks is the one round the nuts that sit above the yoke.

I think I remember this coming up before (don't remember when or where!).  I think that is the seal between the bottom of the fork leg and the outside of the damper rod - it stops the oil just flowing past the damper rod (rather than through it).  So, yes, it is necessary - I suspect that without it there is less damping.  

If you were feeling adventurous you could take the other seal out too (to make both legs identical) and then use real heavy-weight fork oil (which is less likely to seep through the gap) and see what happens - it might be fine!

I think the previous conclusion was that you couldn't order it separately - do check the various Honda parts sites to confirm that, if you haven't already.

Anyway, given you now have some re-chromed forks with a part missing I suggest that the only way forward is to find some bent/broken/cheap forks that *do* have the seal and see if you can do a transfer.

Thanks for the reply. The official Honda parts catalog doesn't show the parts inside the stancions.
First I will try to find a suspension specialist and see if they have a solution. Otherwise I will just reassemble the forks and see what happens.

After contacting a suspension specialist I got the bad news that the part is not replaceable. The better news is that it is not a big problem to leave it out.
So reassembled the forks. Most noticeable when assambling the forks was the real close fit of the new seals and sliding rings. Also the fit in the yokes is tighter as before. The fork with the lost ring was somewhat easier to move without the spring, but it is not a big difference.

A short testdrive showed damping is ok.

Conclusion: find a company that is able to rechrome the stancions as this will save you money. Only use hardchroming.

Glad to hear it isn't a big problem. It's certainly important to get 'hard' chrome on your forks...
