Ohlins fork seals

Recommended Posts

I've had great experience with Dan Kyle Racing in Monterey, CA.

 

He supplied everything I needed for my Scura Forks, but then I ended up taking the parts to local shop for the rebuild. I have the special 4-pin fork cap tool if you need it (but you'd probably rather make one out of thin air...) :notworthy:

 

If you were in Santa Monica it would be worth the 300 mile drive up Highway 1 to pick them up in person.

 

All the Ohlins spec sheets are in the FileShare section:  http://www.v11lemans.com/forums/index.php?showtopic=1427

One thing to watch for when pumping the forks to get all the old oil out: there's a little valve needle that'll pop right out of the long, small-bore damper tube & get lost on the floor if you aren't careful - watch out for it.

Thanks for that..

Just get the Ohlins fluid. It says part number 1309-01.

Ok, thanks again. I'm surprised at the lack of info on this site. Probably everyone already knows how to do it, but I'm going to do a blind leading the blind thread. :grin:  This way, if I'm screwing up, somebody will save me, and everybody will learn.  :oldgit:

Cool - I watched some youtube videos on rebuilding Ohlins forks. I know there are some good threads here on doing the Marzocchis. I was thinking about doing my own rebuild  - I called Dan Kyle and said "Sell me everything I need to rebuild my forks." That's how I got the seals and oil (and special tool). But I ended up just taking the forks and supplies to an Ohlins specialist at Moto Forza (local Ducati dealer).

 

Next time, I'll follow your instructions.

Alrighty, let's dive into this. Here's the patient, nervously awaiting surgery..

The local Duck dealer had the seals.. 5 bux cheaper (Guzzi content) than Dan Kyle, and no shipping. Ohlins is *really* proud of their fork oil, however. 30 bux a liter? :bbblll: At any rate, knowing full well that fork oil does not = fork oil.. some manufacturers 5 wt. might equal another's 10, etc. I coughed and paid. :)

The adjustable pin spanner is for my angle grinder. It fits, but may be too wimpy to do the job. My pup, Tylon, has the cnc mill tied up for a while, though, so if I have to make one, it'll be the hard way with layout, drill press, and band saw. :blink: Yuck.

I *did* make a fork leg holder that way out of some engineering plastic, but that went pretty fast.

Hopefully, the pin spanner will work and we'll get into those fork legs tomorrow. Stay tuned.

The patient appears to be a little chicken.

 

Here's what the Ohlins fork-cap tool looks like. Also pictured is a rod that has threads on the inside to connect to, and remove, the damper rods from the forks. Again - happy to loan these to you.

I made one of those fork cap tools Chuck. Machined out of ally drilled the tool hole and filed it square for a 1/2" drive and used 4 roll pins for the pins. Looks really quite nice and thats with me doing it. You should be able to make something REALLY nice.

Ohlins fork seals from a while back were't great and used to leak a lot, more with bikes that sat around. On my old Ducati SP2 Ohlins forks Honda Goldwing seals were the replacement of choice. No issues with them leaking.

My understanding is the seals that don't leak have more stiction. (?) At any rate, I have these, and they are going in. Looking at it realistically, they could be the last ones. These lasted 8 years and 14K miles.

I've heard the same - that non-Ohlins, more durable seals don't perform as well. I don't have any experience with it but I just figured I would stay with Ohlins parts and supplies throughout. The fork seals on mine sat unused since new - then I put close to 12,000 miles on in 2 years. I detected only a faint weeping, but went for the full rebuild anyway due to age. My shock seal gave up while I was painting the drivetrain and had easy access (I thought that was courteous of her...). Have you ever serviced the shock?
