Steering damper seals

Has anyone been able to source the seals for the steering damper. I have searched all over without any luck.

Thanks,

Re: Steering damper seals

I have used skf 3939 on my 99 .
I had to have my napa dealer special order them from back east.Freight was more than the seals but still way cheeper than new dampner.
Hope this helps.

Re: Steering damper seals

Don't waste your time resealing a stock stearing damper because it isn't a good damper to begin with. I suggest a Hyperpro variable. I installed one, last year, and the results are remarkable. Scarified grooves no longer exist. Steel bridges aren't noticeable. It does take a while to get the settings adjusted to your riding style, but IMHO the Hyperpro is as good as it gets and well worth the money it costs a the time it takes to set it up properly.

Good day sir, I just bought the seals that you mentioned, the number upgrades now to10x20x7 hmsa10rg. I bought 6 of them. but they do not work. I tried many times, but each time I put hard presure on the dampner the oil spurts out. I am a retired BMW master tech with 45 years of doing this. What am I doing wrong. I have to fix it now, I got so pissed off I went and bought a new gtl 1600. So I am now selling the LT. The seal brand is also an skf.

Re: Steering damper seals

I rebuilt my 2000 damper with harwell seals. 20x10x7.....$5.34 each...used 7.5wt fork oil. Fill slowly and actuate to insure all air is out....reassembled and works great. I have two others as spares. Very easy to do with those seals

I took mine apart a while back to flush (the little amount of fluid remaining), clean and refill.
It's working / holding up ok but has a slight weep.

When I watch the damper shaft in action, I can see a slight up & down movement.
Tells me something else inside the damper is worn.
Either the piston seal, piston to housing clearance, etc.
I'll have to break it down completely to inspect.

Not going to do this until I source the piston seal.

My guess is those that have put new seals in and still have a leak may have this issue.

Re: Steering damper seals

I just ordered seals for my bike. When I took the old seal out I found it to be a KACO lip seal. The number was OHWA 10 . 20 . 7/8.5 VGF01 . This is the original seal that came with the bike. I called Accent Bearing in Addison, Il. and told them what I need for seals for the steering damper. They told me they could get that exact seal. I ordered two but will report back to the group to let you know price and how I like them.

I used Google translate to read the page.

After translation -
The picture next to "Steering damper BMW mod. 2, interior details." looks like either a break down or it may be all the parts included in a rebuild kit.



All I really need would be the two seals, the four piston seals, and the two o-rings.
I could not find the option to order, what may be included, or a price.

aquachrono, Could you help with this?

Thanks, Ken

Re: Steering damper seals

For what its worth I just rebuild a damper for a guy and used these seals BocaBearings . They were 6.95 each and although they were not exact replacements they appear to be working just fine. I replaced no other parts as all the little o-rings were reusable.

Re: Steering damper seals

Ken, I am not speaking italian but I asked a friend which does , to call monday the Rinaldi shop in Italy and request the prices for seals and o-rings, and options for payment and shipping. I will let you know as soon as possible. I am also interested in buying a set . My steering damper is not leaking yet but is better to have the parts .

Re: Steering damper seals

Gary,

I damaged the original torx head bolt and ended up drilling it out. I did replace it with an Allen head M8 x 45 from the local hardware store. Tried a hex head but that restricted the movement of the damper.

Used Google translate to send a message to send a message directly to Rinaldi.
Here's the message I sent.

"Hi, Do you sell the BMW model 2 steering damper kit? There are quite a few of us in the USA that would like to have them to rebuild the steering damper in our BMW motorcycles. If yes, please email back with the cost for the kit and shipping to the USA. Regards, Ken Child"

Here's how it translated-

Ciao, Vendete il modello 2 Sterzo Bitubo BMW? Ci sono un bel po 'di noi negli Stati Uniti, che vorrebbe avere a ricostruire l'ammortizzatore di sterzo nelle nostre moto BMW. Se sì, per favore scriva di nuovo con il costo per il kit e la spedizione verso gli Stati Uniti. Saluti, Ken Bambino

I have no idea what that says but I got a reply back this morning.

Ciao
Faccio la revisione ai modelli originali BMW ma solo nella sede in Italia.Non vendo ricambi per la revisione.
Costo medio revisione in Italia 110 . Saluti Rinaldi G.

Which Google translate's back to -

"Hello
I review the original models BMW but only in the place Italia.Non sell spare parts for review.
Average cost revision in Italy 110. greetings Rinaldi G. ."

I think that says he rebuilds the original in Italy. Doesn't sell part for rebuild. Average rebuild cost $126" (or 110 euro).



Gave it the ole college try but don't think that's going to work out...

Ken

Re: Steering damper seals

Sometimes google translate makes me chuckle like how it translated your name from Ken Child to Ken Bambino.

I have a German friend who's last name is Keller & google translated it to Basement.
