OHLINS

[S251]

A funny thing happened to my Scura at about 8,300kms on the clock. The forks wore out and the seals gave way. Strange or normal I do not know but very expensive I expect.

 

The rear shock just stopped working from time to time and then gave up altogether.

 

I had mentioned to the dealer that all was not well for over 12 months in the warranty period. The response was let it work itself in an all will be fine. Not so.

 

The forks are out to the doctors for a good fix up. Any comments on this strange tale whilst I wait for the repairs?

 

Thanks

Ohlins forks have loose seals, so it can react very sensible. So is also it very sensible to dirt. The front mudgard doesn't help here. The ones from the RSV protect better. But the same problem do owners of ducs and aprilias with Ohlins forks have. Best place to replace is a suspension specialist.

24000 km aint had that problem yet.and don't want it.

good luck with the repair.Gilly

What do you mean by "the forks wore out"? The stanchion surface? the bushes?As Paul says, seals are a loose fit for reduced stiction & fail regularly (I've had anywhere between 3-7k miles) & start to leak. Replacing the seals fixes it. I have 17k miles & AFAIK surfaces are good.

If dust scrapers & seals are good, dust shouldn't be getting into wear surfaces??? But I guess if you're in a very dusty area you could have problems, & the fact that botrh ends gave up....what happened to shock? Was fork oil ever changed?

I also fitted RSVR guard, but it really needs an extra strip down the side to fully protect stanchion fronts.

Martin Barrett came up with an idea that leaving bike on sidestand for long periods may set seals & promote leaks - dunno, but now I try always leave it on workshop stand.

Ohlins are really designed for track use hence the problems in road conditions.

Yes the gold stanchion surface wore through to the bright chrome and the seals fail. No dirt riding only city and highways. The bike has been we me from new but in the shop for 2 years and serviced by the dealer for sale.

I use a becker stand.

 

thanks

The gold is PVD titanium nitride and is hard but very thin. I mean microscopically thin, to the extent that you would not be able to measure the difference in stanchion diameter.

 

If you can live with the "worn" appearance, simple seal replacement should be enough to restore the forks to operation. Obviously, the anti-stiction properties of the TiN is lost to an extent, but I doubt if you could really tell the difference on a V11. The TiN coating is more a fashion finish and less an engineering surface treatment on a road bike.

Thart's the 2nd prefered option. The best option is to ride it more

Sir Nog, I applaud y'er penetrating analysis. In a world where the dominant Popular Kulture is obsessed with Symbolism over Substance and Appearances over Reality, where the lemmings have been conditioned not to get below the surface and not to see the forest for the trees, but rather to suppress individual thought and "go with the flow", and where bling and flash trump all that is proven and sensible WRT motorcycles, you possess a unique perspective in your time.

 

You've been elected to the Order of the Rose Garter at the quarterly meeting of the Knights of the Absolute.

 

Congratulations are in order!

 

BTW, I've sent my Squire, Igor, 'round. He has instructions not to leave until your sags are properly set, and he will not leave until you pass muster. He suffers from a number of particularly offensive afflictions, at least a few of which are highly communicable, according to local scuttlebut from the tavern wenches. I suggest you get to work.

First of all, what does this have to do with absolutism?

Second of all, I disagree with Nog's recommendation to live with the worn tubes.

I'll bet you if he does not replace the tubes he will see seal failure within another 8300km.

Third of all, we all have are vanities. Some get all frayed when you start criticising their Harley vanities, and some have immaculate bikes and classy black leathers, refusing to wear tacky colored garb.

Who gives a crap,buy what is on sale that is of sufficient quality, and suffer with the cheesy bright colors.

By the way, I have some purple and yellow leathers that will fit you perfectly for sale, cheap.

Search me, but I'm flattered.

Worn? Your definition of worn is too expensive. These tubes have only lost a few nanometres of gold coloured PVD. You may disagree, but my recommendation is based upon a degree in metallurgy and surface engineering and many subsequent years of experience as a designer and consultant in the heat treatment industry. I have actually designed the PVD equipment used to apply this stuff in the past and think I know what I am talking about.

Lost... totally.. Have you been eating mushrooms from the woods?

Nog, latter-day Philistines have no respect for either University degrees or hands-on experience - even their own. As demonstrated so thoroughly since January elsewhere, they have been conditioned by professional Propagandists to believe that if the entire depth and breadth of any highly accredited, highly specialized academic and/or professional field of knowledge can't be represented in a single-frame cartoon with a one-line caption, it has no meaning whatsoever, and may as well not exist. Hence the length of the Global Warming thread. . . .

aw geez. Not this crap again. Please leave this shite in the GW thread where I don't have to look at it.

Howz it goin', Ryan?

 

Your contributions are always such positive, uplifting additions.

 

Is there someone holding you at gunpoint, forcing you to read posts that you aren't interested in?

 

Are they then also forcing you at gunpoint to reply to the stuff you aren't interested in to complain about it?

 

Are you related to that other guy who does the same thing?

 

Enquiring minds just gotta know.

As a disinterested and unbiased third party I have to say that the posts from rachethack are some of the most entertaining on this forum. They are always comprehensive in nature, even though I don't always understand what is his point.
