Suntour Coil Fork - Lower Leg Service
Vložit
- čas přidán 5. 09. 2024
- Join me in this 'How To' video to learn how to perform a lower leg service on a budget coil fork. My fork is a Suntour SR Raidon, but this pretty much applies to any coil fork that you would want to perform a lower leg service on. It is not as hard as you might think, and definitely worth doing. My forks didn't have hardly any grease/lubrication inside, and that needed to change!

Just to let you know: this video has helped me. I was looking how to remove the rebound twist dial on my raidon fork in order to install a remote lockout cartridge. Now I'm less scared to try pulling the fork apart and back together again. Thanks
Same here - had the rebound adjust allen bolt stuck in the outer screw and hadn't thought about simply pulling it off ;D Now that I know everything went fine and my raidon runs smoothly with fresh grease/oil =)
You're better off using isopropyl alcohol on the stanchions because it evaporates. Soapy water could leave a residue behind. 👍
I find it easier to do this with the bike upside down so I can put my foot on the handlebar to separate the outer fork from the stantions. This makes a huge difference on an older mtb so I agreed it’s totally worth.
I've read on other videos that the cavity under the wiper seals (where you put the grease) can take foam wipers from other forks. They are soaked in oil and apparently make the fork much better.
Just took my Marzocchi Bomber exr forks complete apart serviced them for the 1st time on my own. Easier then I thought but I had a great video to go by. Helped a shit ton.
This is so chill. Wish I could have you over to coach me through this in person haha. Mega love this video
Thanks for the feedback! I hope the video helps you out.
At last, someone with personality on CZcams. Well done mate, great vid.
Nice one. Same bike really useful.
appreciate the video!
nice video. and i have triffords in my garage as well
Thanks! The plants? Haha, the neighbour is letting them grow up my garage wall and they keep coming in. More expanding foam maybe? Or maybe they should actually run a fence all of the way down their garden!
My airfork lower screw on non drive side, i cant take it off. It just spin freely. And i cant even tighten it. Is it NOT GOOD? What to do?
The the Halfords Teflon grease your using can you use it on the coil spring itself
And also have Suntour SR raidon
I have a set of suntor XCR32 Coil Forks and have had then for 2 years,
They have been good and I need to service the lowers to remove grime and re lube. I serviced my friends XCM forks and they were fine. However, when I tried to service my forks, the nut on the bottom just keeps spinning meaning I cannot remove the lowers. I have tried everything like giving them a hit with a mallet but nothing works,
Please help

Hey man I've bought a voodoo hoodoo frame and I'm building it up from scratch going to respray as its blue, iam sure what year its? And need to buy a new heardset berings top and bottom could you help what berings do I need to buy ? Thank you love the channel
Is it normal to be getting black ring marks on the stanchions when riding after doing this? I think I over-greased the seals?
Alright mate would this work on the voodoo bizango with the air fork ? Also didn’t you fancy adding a travel measure o ring while you had the bottoms off ? Good video thou will deffo help when I try mine as my rebound isn’t working
There's so many bloody variants I don't know what my fork contains. I have NCX D-LO. I assume it's coil and don't have to worry about oil?
There is a coil NCX-D-LO and air NCX-E-LO version. You need to read the little sticker and look up on Suntour's website. There you find all detailed schematics of these forks. I have both, coil and air and they are excellent. They are greased, not oiled.
All Suntour forks, whether coil or air, have grease in the lowers. No oil. I have the Raidon LO-R (air) and it only has a bit oil in the air chamber (does not leak when you pull it apart).
My preload cap doesn't work its stuck and I have leaking oil on the legs that get black and the seals get so much dirty..
Nice video👌👍🏻
But I was wondering if you could do this service on a coil shock from rockshox as well
You can, but there may be oil in the lower legs. A bit of research on the web for your fork model should tell you which oil, and how much you will require.
@@AshfordMTB thanks a lot 👍🏻
I have rust on my stancions. Can I remove it with fine sandpaper?
To try and salvage them I would try a metal polish and rag first. Sandpaper could well be too harsh, but depending on the amount of rust that is present, you may have to. Maybe even a scotch brite pad before polish. Use the metal polish after to get it as smooth as possible. Only problem will be is that the rust will return. Always wipe them down after a wet ride, and maybe smear a very small amount of fork oil on them.
@@AshfordMTB Thanks for the quick reply. I will try metal polish. If that does not help I wil find something like the scotch pad.
there is black greese type stuff building up on right but not the left, do you have any clue what it could be
I would say that it is lack of grease on the inside of the wiper seals. I had this on both legs until I performed the lower leg service.
@@AshfordMTB thanks for the info man! also there is some scratches on the fork where the black resedue has collected grit and has scratched my forks, do you know what I can do about scratches
Depends how deep the scratches are. As I mentioned in the video, some really fine wet & dry paper with some metal polish. If you can't feel the scratch with your finger, I wouldn't worry about it. If it is quite pronounced, it may have damaged your wiper seal.
Sort the scratch if needed, perform the lower leg service and have a look at the wiper seal on that side, if it looks damaged, best get another pair of seals.
Good vid
hi!is there a possibility to increase the travel with at least 10mm?
If it’s an air fork you can, u can check if it’s an air fork by looking for a thing that says air on the top of it
What would you recommend setting the preload and rebound I have the exact same bike
its different for every riders weight and ride style and what they like to ride mess about and see what you like the best
My Budget Sr Suntours are even more budget then those in the video 🤷♂️ 😬
Is there a spring in both stanchions or just one?
Just one in the non-driveside stanchion.
Predictable
Synthetic grease is what we need... forgive me but ...This fork is an air/coil fork surely? Air one side rebound coil on t'other. You said the left hand top end was preload adjustment? That's the red nipple you took off on the bottom r/h ... I'm pretty thats your air valve up there top L/h

It is a coil fork.
Red adjuster is for adjusting the rebound.
suntour raidon is definately air sprung
They are air aren't they! Also he says there is no serviceable parts at the top. Well the air cartridge in mine was gunked up with residue. Cleaned and 5ml of SAE80 put in. Ive since upgraded fork as the Raidon was simply dreadful ...
Treat yourself to a clean rag lmao😂
The sound is too low to hear anything he says :(
Zzz
Didn’t appreciate the background sounds over the talking.
Oh stop crying. Don't watch nobody cares.
"Coil".......
Step 1. Find a dumpster (tip in England). Step 2 chuck the fork in there. Step 3 Buy a proper fork. Step 4 Install it. Step 5 ride it and enjoy a proper functioning suspension. You're welcome
I have had a couple of budget forks the coil sr suntour xcr with the 34 mm stanchoins is o.k.
