Good video, thanks. I don't think the 25cc of oil in the lowers is necessary though. Suntour prides themselves on this VS Fox and Rockshox; who do use an "oil splash bath".
@@Paulklampeeps It's out of warranty but the bike has only done 200kms. I pulled them apart and encased the spring in an old road bike inner tube. Seems to have done the trick. Shouldn't have to do this if they were correctly assembled and designed in the first instance.
HI! I just did this service today and it went pretty well. Only thing, my Lockout is not working anymore... any idea what could be causing that? I still have rebound adjustment so I guess the cartridge is not damaged... Thanks for your help!
Probably it has something to do with the oil... Opened mine and put in hte damper side 60ml of 5w oil, lockout doesnt work so either it needs more oil or thicker oil... nevertheless i dont think it will damage anything, just the lockout needs more or other oil to lock itself
@@DoctorORBiT then why mine cape factory with a crap ton of oil in the oil damper?? Even the lbs suggests oil in the damper side plus I run it about a day with no oil and it felt garbage and the lockout didnt work
Bonjour, quelle graisse utilisez-vous ? Y a t il de l'huile à ajouter comme sur certaines fourches ? Je dois changer ma cartouche (REF FUN066-38) pouvez-vous faire une vidéo pour le remplacement de celle-ci ? Merci par avance
Anyone know how to fix lock-out not working? Mine came with remote but makes no difference whatsoever, the fork continues to use significant travel when bouncing on it.
Don't put oil in your lowers. Suntour forks are grease based, not like Fox or Rockshox which use oil. Watch this instead: ua-cam.com/video/YIeJ7Vf1bxw/v-deo.html
In Poland there is a proffesional service/shop that does this step as an upgrade for customers that wish to have it done. I suppose this means it doesn't leak. I saw the same oil weight used on another video, but uploader wasn't sure either and I haven't seen anywhere else any people that used such heavy weight oil for this purpose. I need to service mine too, and my notes say 2,5W oil, but it may apply to air chamber, as I'd prefer not to add oil to the bottom for quicker and cleaner service procedure. If service isn't a hassle everyone tends to do it more often. It's much better when you don't have a garage or a workshop -no risk of spillage. Most other forks use 15W oil in lower legs.
Just checked that shop which only sells and services Suntour forks and they carry Fuchs Titan Supergear 80W-90 and they describe it as air chamber oil for suntour forks. They also sell Fuchs Silkolene RSF 2,5W; 5W; 7,5W; 10W; 15W It's probably quite expensive and harder to get, but a really good one. If You're not very demanding user, any motorcycle fork oil of similar weight will be good. They can differ quite significantly between brands, cause of CST factor. WT is bullshit, CST is the real, comperable viscosity characteristic. Rarely on the label, normally available in pdf documentation from manufacturer website.
80w like he used for the seals. You can also add a little in the lowers (5-10 cc) to make it more progressive, but don't add more than that. Suntour forks rely on the grease and don't have oil baths like Rockshox and Fox.
You can add some Teflon tape to the top cap threads or if it's leaking from the valve, you should replace the valve core, you'll need a valve core remover for this.
Grease and oil? Wrong oil for a start, that 80w gear oil only goes and the air chamber to lubricate the air seal and no more than 4cc. Don't put grease on the seals, they don't mix! its one or the other and 25cc in each leg is to much. I use 15cc 10W SUSPENSION fluid max in each leg. Release the air before touching the forks, good luck.
sr suntour air forks don't take oil in the lowers. That's one of the distinct characteristics of suntour that separates them from rockshox or fox. They claim is easier to service the forks by just using grease in the lowers and maybe like u said 4 c of gear oil in the o rings and seals
@@renenavarro4121 totally agree with you though I found to much sticktion even a week after service, they do run smoother with oil though the aions have foam rings soaked in oil.
@@darrencardy2119 cool I have aions too the 35 evo pcs. Recently upgraded the negative spring and the cartridge. Feels super plush. I had the remote lock out damper which didn't have much tunning options
This is a great tutorial, thank you so much!
Are the seals the only part you should grease on a fork like this? I read you should grease the bushings as well, but I can't see any on my model

Have fun killing your forks
@@mountainbikemike actually I have to agree with @JK on that - oil bath are not recomended in SR froks
Yeah they say you can add 5-10cc to make it more progressive, but that's it.
i was gonna say this too. sr dont use oil in the lowers just the conpana grease they provide. I do put 8 cc on the air chamber tho.
Agree, SR Suntour Aion forks do not need the 25cc being shown in the video as confirmed by SR Suntour Customer Service.
Great video! Thanks
Oil on the lowers are optional. Will just make the next service messy.
Mine rattle like crazy over bumps and are near new. Any thoughts on how to remedy the problem? Thanks!
Is it brand new? If it's definitely try to get warranty

Is it the same procedure for the new Axon 32 mm?

There's not a true lockout. There will be a few mil of movement even completely 'locked out'

again, there is a bunch of oil in there. should you not put some back? If it was only! grease none would be all over my floor.
Does it leak the oil? Because there are no seals at the bottom of the lowers...OEM there is only grease. I want to service my Aion, too.

Yeah...just read that Aion does not have seal in air side lower leg, Auron does. So this might leak, not sure.
Did you solve it? As?
@@janochavez I've got 80w90 oil in my Aion, and it doesn't leak. I've assembled the bottom with a bit of grease tho, so it might help with sealing.
Thanks man!
no oil in the lower casting
Cartridge pcs?
What wt of oil you use? Please help me!

@@CodyKing oil in the lowers has nothing to do with progressivity, oil in the air chamber does
@@CodyKing 80w is for air chamber only as its to thick. Use 10w suspension fluid.
Thanks!
Thanks for the how-to! Love the white & Orange DB! I have a maroon release 1, previously orange option. What year/model is that?
2019 Clutch I have the same one
please give me tutorial about setting travel 140 to 150 Aion
Thanks
Salut quelqu'un aurait les références de tous les joints / huiles / et graisses

não vai óleo na lower leg pode vazar no futuro só graxa é o ideal
How to fix air leaking in fork example my psi is 100 but after 72 hrs the psi is decreas into 60 psi
You can add some Teflon tape to the top cap threads or if it's leaking from the valve, you should replace the valve core, you'll need a valve core remover for this.
100psi is insane!
You are supposed to have 5 ml or so of hear oil in there which should stop any air loss
@@jondotcom8706 that's what i was about to say
