Leaking fork, how urgent?

Leaking fork, how urgent?

Post by Jonesy on Mon Nov 07, 2011 5:30 pm

Okay, I know I've been needing to service my Fox fork for a while, but I'd like y'all's collective opinion on how urgently it is needed.

There is oil seeping onto the stantions. It does not form enough to drip or pool, but the stantions tend to grab a lot of dirt and dust and a thin film of oil is constantly on the stantions. Additionally, there is a significant deposit/film of oil on the left seal that is gathering a good bit of dirt/grime... similar to what you might see on an automobile manifold with a very mild leaking manifold seal.

There is no evidence of oil 'splattering' or otherwise leaking a tremendous amount, there's just a constant film of oil on the stantions and the seals.

I don't hear any strange noises, or notice any performance sypmtoms in the fork.

Does this sound like something that I need to urgently take care of.... like prior to Friday's Neustadt ride?

Thanks,
Jonesy

I don't like leaks myself so I would either fix it or have some one fix it. Remember the system doesn’t hold much fluid so any leak is a bad leak. Earlier this year Steve took his into Toxiholic and they had it completely rebuilt in less then four hours. Fridays ride is no joke and you don't need your equipment failing at the wrong time...just my 2€...

Oil is supposed to seep from the wipers onto the stantions! That's the design, there's a fiber sponge that holds oil under the wiper seals that is there to lube the sliding part. When it goes DRY is when you need to service.

Agree with Euro. It is normal for a fox. The felt wiper is there for that reason. When you do decide to service the fork, I would suggest Enduro wipers instead of Fox. Work better and keep more crud out.

Thanks guys. I did know that oil on the stanchions was part of how shocks worked... just wasn't sure how much was normal. I was kind of leaning towards the "When it dries up is when I should really worry" conclusion anyway, so thanks for the confirmation.

I think you need to coat the stanchions with a thin layer of JB weld, let it hardened and then sand it down with 800 grit sand paper. This will create an added layer between the seals and the stantions which should prevent any leakeage. Smile Smile

I had an inkling that you'd not fully recovered from your head injury. This confirms it! Surprised Razz

There should be a "film" of oil on the stanchions. But it should not collect dirt, or pool/ leak at all. Nothing to worry about though. Just get new seals when you service the fork next (should be done once a year anyways)

On the note of seals, Enduro and Fox both make a great product now. The 2012 seals from fox are top notch! Felt a buddies 2010 Fox 40 with the new 2012 seals. Felt like night and day compared to the old seals that Fox has put out. At this point in time I would not spend the extra $$ on Enduro Seals for Fox Forks. Now Rockshox forks.... I'd run Enduro seals for sure!

The new low stiction seals are $25 a set. Exactly the same price as the Enduro's. They won't even sell you the old ones any more that were $12.

Very interesting. I was very supprised on how good the new Fox seals felt. I can only imagine how good my Van RC2 would feel with "low friction seals" Very Happy
