The English term for Simmerring / Gabeldichtringe?

Post by hashamyim » Thu Oct 17, 2019 8:22 am

Hey there,
So I am a newbie to motorbike riding and have bought myself a Honda CBF1000 - yippee!
Unfortunately, in order to pass the German MOT test (TÜV), I apparently need to have the 'Simmerring', also sometimes known as 'Gabeldichtringe' replaced.
I am trying to find out what the English term for this is and am coming across a bit of a stoppage. Was wondering if anyone here might be able to tell what is going on from the following information.
This website (in German) tells you how to replace the 'Simmerringe': https://cdn3.louis.de/content/cms/3414/ ... tringe.pdf
The dictionary describes it as: shaft seal, oil seal, lock ring, retaining ring, rotary shaft seal...
I would really like to start learning how to maintain my own bike and have bought a book, but none of these terms appear in it.
Does anyone have any recommendations as to what I need to be looking at?
Sorry for what is undoubtedly a school-boy question...!
Regards,
Hashamyim

Gabeldichtringe according to google is fork seals, quite an easy job with basic tools. Be care full about getting the old ones out, dont just use a screwdriver and just oink them out, do it a little at a time each side of the fork leg.
When installing the new ones use a big socket that will fit inside the fork leg where the seal sits and tap the seal home gently.
Refill with correct amount of oil. Do one leg at a time that way you have a reference as to what goes where.
Not sure what oil you are supposed to use but we always used ATF (automatic Transmission fluid) it puts up with a lot more than ordinary oil and give a nice ride. Ordinary oil get clapped out real quick in forks.

Yes it means shaft seal and it is not necessary fork seal,
Shaft seal, also called Oil Seal, in machinery, a device that prevents the passage of fluids along a rotating shaft. Seals are necessary when a shaft extends from a housing (enclosure) containing oil, such as a pump or a gear box.

But in your case most probably is about forks

Oh I wasn't complaining! Any content is good for me. I'll update my x-ray injury thread now.

I feel compelled to say that is a bit of a over simplified description of changing fork seals . You have to separate the stanchions from the lowers ( sliders ) first .There is often the issue of preventing the cartridge from revolving when the external bolt is removed. Then there are the bushes to inspect / replace according to their condition . Tapping in the new seals can often be done by using the old ones as a tool providing that you didn't mutilate them getting them out . Probably best to refer to the manual if this is s job never before attempted.

Never used a tool for removing the old seals, they did not exist on my day. Fork seal and replacement along with bushes is a relatively easy jobs with pretty basic tools, it's not like changing mains and big ends bearings.
Yes dropping the legs from the tubes can be awkward but not impossible. It should also be mention for tube inspection for stone damage, this will more than likely damage the new seals if the damage is on a section that enters the fork leg.
