Ducati 1098S Service - Changing the Oil & Dust seals and replacing oil on Ohlins forks model FG5110

Hi Everyone, last service video on the Ducati 1098S, in this one I am going to be carrying out a basic service on the front forks which are the standard Ducati 1098S Ohlins, model number FG5110.
In the video I will be stripping and cleaning all the major components before replacing the leaking fork oil seal, dust seal and refilling with fresh fork oil and setting the air gap back to the standard setting.
If you enjoy the video, please like, share and subscribe for more content.
This bike will be listed for sale shortly and I will load a video to show potential buyers around the bike.

Thanks Kris, you too 👍🎅

Es la misma suspension que trae la scrambler 1100 sport 2019? Tengo que hacer el cambio de sellos. Y queria saber si lleva la misma cantidad de aceite. No encuentro el manual especifico de la misma . Gracias.

[@pabloalbe9550]

Olá,eu tenho uma Ducati Monsters 1100s ano 2010,e a mesma suspensão que você arrumou

[@teobecks748]

Great video as always !!! Only one doubt: why didn't you close the fork cap to the tightening torque, not needed? What tool did you use for the cap? What paper did you polish the stem with? Ok ... there are three questions ... :D

[@DesmoWerx]

Hi Teo, Cap is only done up to 10nm which is not much more that gentle force, I used a pin wrench (similar to angle grinder disc tool) this time but I also have a cap socket for the ohlins. I used an 800 grit wet and dry paper to clean the stanchion.

[@targetoz5470]

Gday mate, my manual says 155cc by volume and doesn’t mention anything about 155mm. How did you get the info for measuring 155mm. Cheers Steve.

[@DesmoWerx]

Its on the Ohlins service card for the FG5110 fork. Use 400 cm3 of oil with an air gap of 155mm

[@wellertsai9270]

Excuse me, exhaust air, that's just M?

[@jimlora3358]

where did you buy the seals?

[@DesmoWerx]

I usually get mine from Reactive Suspension in York UK

[@gregbenn5664]

Get that shit box car out and make some room

[@sebieusebeuse4838]

13:43 I love that. Do you love me? 😍💋 💝💖❤️

[@DX-tk6fy]

How come there is no bushing at the top of the stanchion? Is the bushing in the slider extra long to compensate for no bushing at the top of the stanchion?

[@DesmoWerx]

Bushes are in the outer tube only for the Ohlins forks. Not much different in size.

[@DX-tk6fy]

​@@DesmoWerxGotcha. Is the top bush pushed in from the bottom of the fork tube also? I'll find out shortly anyway as I'm stripping them in the next week

[@starfighter2952]

Shouldn't you pump the damper rod to fill it with oil before you measure with the syringe?

[@Nellie-zv7tz]

Hi Starfighter, you do. As I am topping it up you will see me pumping the rod up and down and then measuring it one there is a resistance in the cartridge assembly.

[@DesmoWerx]

If you check out the video you will see me pumping the rod assembly and explaining why 🙂

[@harryohanson]

May I suggest putting seals on inner tube first in order of dust seal, lock ring, oil seal and washer. I find that added security that fork will not leak due to damaged seals.

[@DesmoWerx]

Hi Harry, I normally do it that way, not sure why I took the more awkward route this time round lol

[@tobiasjacobsen_dk]

Nice and very informative. As always! Can you point mere towards the tools used to do the fork service ?

[@DesmoWerx]

Hi Tobias, I got most of the tools I use for suspension from here when I did my suspension courses. www.reactivesuspension.com/

[@nickbright6028]

Thanks for this video Just what I needed so I could rebuild my Monster 1200S forks Nice work!

[@DesmoWerx]

Glad the video was of benefit to you 😊

[@triumphspeed1090]

Great video, can I ask how you identify the model of Ohlins fork you have?

[@DesmoWerx]

They are usually stamped on the bottom of the fork leg, either at the very bottom or on the lower face of the caliper mount.

[@jamesbazel3384]

Nice vid, this will help me while doing the seals on my 1098S.

[@DesmoWerx]

Glad it was of help James 😎

[@hazabaijan]

If I want to replace the oil in my 996 forks, are oil and dust seals the only parts I need to replace?

[@DesmoWerx]

Hi Harry if just doing an oil change you can get away with just the oil and dust seals. Personally I would check the bushes are not excessively worn as if they are then you might as well replace at the same time 😊

[@mazenbira1776]

Can I have your e mail I need to share some photos of my ohlins fork for my ducati scrambler 1100 sport it has a scratch on the inner tube fork which started leaking a while ago and I need help to fix it from an expert

[@DesmoWerx]

Hi Mazen, my contact email is on the "About" page or you can message via Instagram 😊

[@sinasihaznedaroglu5686]

Hello, Love your videos. Thanks for all the info and time spent on them. I recently serviced my forks on my 012 ducati streetfighter 1098s. It was leaking from one leg and following your instructions, I was able to service them. However, my rebo7nd damping turns 30 some clicks. Does that sound right to you? If not, what do you think I did wrong that it now reads 35 clicks? Thanks again Gino

[@marklupton2064]

Great stuff, love the videos , did an oil change on my 888's forks after seeing your st video 👍

[@DesmoWerx]

Glad it helped 😎

[@MaciusSzwed]

So how much oil did you use per forkleg? 380 ml? What type of oil? 5W Motul?

[@shanebingham8137]

Do carry out any private work at present.

[@DesmoWerx]

Hi Shane, send me a message and I will see if I can help. 🙂

[@molez100]

For progressively wound coils is there a correct orientation?

[@DesmoWerx]

Hi James, it does not matter which way they are orientated.

[@norbertglummercz1406]

what is the weight of the oil? 7.5W?

[@Woopy11]

Lotus espirit?

[@DesmoWerx]

Yes it is :)

[@sinasihaznedaroglu5686]

Hey Nellie, Thanks for the video and all the others. They are super informative for us DIYers. I serviced my forks with your instructions but my compression damp8ning now has 35 clicks on both legs and I cannot understand why or if thats what it should be. My bike is 2012 ducati streetfighter 1098s. Any suggestions will be appreciated, sir. Thabk you and please keep up with great videos.

[@sinasihaznedaroglu5686]

Can anyone give me an 8dea why this would happen? Thank you

[@vintagevalhalla7523]

I am no expert, as I just recently did my forks for the first time… but on assembly, it seems an easy mistake to make is to not fully seat the cap onto the damping rod. In this video, I believe he uses a notched plate to hold the spring compressed against the lock nut (fully threaded down). If you don’t do this, the cap is going to mate to the top of the spring retainer before it is fully seated on the damping rod. It seems this would create a gap between the adjuster and the damping rod, causing more clicks to get into the adjustment?

[@DesmoWerx]

If they are both 35 clicks then thats likely the adjustment range on your forks, I don't have any data in my service manuals or service sheets that tell me the full range/number of clicks. I was always taught work from fully closed when setting them up so never counted fully out, the manual guides the same as well. As I don't have one in the workshop now I cannot check to see what I have as a range. Sorry I cannot be more help.

Thanks for watching 👍😎

[@michaelduffy8128]

I don't know the mileage on the forks, but I was wondering why you didn't change the inner and outer bushings while you were in there?

[@DesmoWerx]

Hi Michael, there is no wear showing on the bushes, the bike has only done just over 3500 miles in total, and only about 700 of that in my ownership, they may have been replaced before I got the bike as they look pristine.

[@michaelduffy8128]

@@DesmoWerx love your channel, watch every episode and enjoy the information you present. I have a 2007 Ducati 1098 with 63,000 mi on it and I've been able to gain a lot of it helpful information from you, keep up the great work.

[@martinbe9384]

Is it the same on 998s öhlins forks and other 916/748 series bikes with öhlins?

[@DesmoWerx]

The process is pretty much the same but oil levels/air gap may differ, its been a while since I serviced some of the older Ohlins forks.

[@martinbe9384]

Thanks mate, love your videos. Hope you can post a video soon servicing older Ohlins forks:)
