Suntour XCR Fork Service - Disassemble/Clean/Lube/Re-assemble
ฝัง
- เผยแพร่เมื่อ 20 ต.ค. 2019
- I show how to tear down, clean, lubricate and rebuild Suntour XCR forks/shocks. This model has lockout. Periodic maintenance will help prolong the life of the fork and maintain performance. Basic service to keep your suspension working and from becoming stiff or frozen. The XCR fork models have varied over the years. This fork is a SR Suntour SF-14 XCR-32 LO Fork 29".
* at 7:24 & 7:33 , I said counter-clockwise, but they should be clockwise.
* Use grease made for forks. I use Slickoleum which is also sold under the name Slick Honey. You can also use SRAM Butter or Judy Butter. Use of a grease not made specifically for forks can damage the plastic/polyurethane parts, or otherwise leave the fork not working properly.

Can I ask what is better?
Xct Xcm or Xcr???
And can you also shiw us how to convert this coil fork to solo air fork? And to adjust the travel to 120mm
@@cyclistcris7963 I think it goes from XCT to XCM to XCR being the best of the three. If you want an air fork with 120mm of travel, buy an air fork with 120mm of travel.
Man, this channel is pure gold to us low-budget cyclists! Any idea about how to do-it-yourself repair (as far as is possible) of damaged seals on air shock forks like early Marzocchi Bomber, exactly like on this bike?

Do i have to release the lockout before removing the lowers? Tia
You missed something. Service should include taking out the seals so you can also pull the plastic sleeve bearings. Seals slide out with encouragement from a flat blade screwdriver. Then reach down inside the lower and work out the sleeve bearing- one per side. The sleeve bearing is what actually contacts the stanchion. It MUST be cleaned and relubed. just dabbing grease down in there with a stick is not enough. Clean the seals too. As an annual service you should clean and lube seals and sleeve bearing, clean stanchion, but don't bother with all other stuff. The spring doesn't care if it has fresh grease on it. The way these forks fail is wear or corrosion of the stanchion, and that is controlled by seal and sleeve bearing. In your 2014 video servicing a Suntour T890 fork, you did get the sleeve bearings out and cleaned. The sleeve bearings are a very similar design to what I found in my ~2013 XCR 29er.
Man ! I swear your video is precious as hell. I'm from France, bought a rather old bike sold by a huge sports brand that has this exact same fork. Unfortunately, they don't provide any tips to clean and service this fork, so I had to scatter all around the web to find how to service mine correctly, and I found yours !
Again, keep going with your videos, you're awesome, and you're helping people all around the globe !
En principe t'es presque pas censé faire de maintenance sur une fourche à ressort :)
yeap，u just speak what i want to say
@@KRaikkonenSF oui c'est vrai mais j'ai la même fourche et elle est devenue dure, le locket tourne dans le vide et la vidéo va m'aider à la démonter et entretenir pour régler tout ça :)
@@KRaikkonenSF Moi cette video va m'aider a changer la cartouche sur mon vieux Rockrider, le lockout ne fonctionnement plus, cartouche morte ;D
@@laurentfly5362salut, as-tu réparé ton verrouillage provoquant le vide ? J'ai le même problème. merci
Dude thats the best ON BUDGET fork. I have been using it for like 3 weeks now. Im always on the road traveling from house to farm. The mechanic tinkered my xcr from 120mm stantions to 150. Man its a boost. I only spent $40 for everything including materials needed for the extension of the stantions and mechanics' fee. The best fork for $40. 👍
Thank you for this tutorial. I just completed this maintenance with your guidance on my 10 year old Rockhopper. It gets new brakes in the morning.
Always good to see these videos in your library, very handy to have a reference should you come across them...
Great video, didn’t realise my fork was so simple and straightforward, think one I can tackle myself. Thanks!
Good video, very straight forward and informative. But there are two things to point out
You should not use a metal hammer to tap on the screws at the bottom of the lower or you risk damaging the dropouts, and make sure to remove any preload from the coil before dissasembly/assembley. Thank you for another video.
Thank you! Just successfully repaired my XCR today. I had to wait for the wrench & grease which I bought online but once I had them, it was a breeze. BTW, mine didn't have the lockout. Both just had the same pre-load dial.
Great job, RJ!
I've just come by these forks, 2006 I think, so will be following your plan! 👍🏻
Really chuffed I found this as my forks are seized and now I know how to recon the unit. Really useful video. Many thanks for sharing 👍
Thanks so much for this detailed explanation and tutorial! Exactly what I needed to know for the maintenance on a bike that I bought for 20$ on eBay. Take care and stay healthy 🖖💪👍🌞
Thank you RJ! I was scared to disassemble my fork suspension cause I'm afraid I might mess up something this tutorial of yours helps me a lot for future maintenance
I’m not a mountain biker but I enjoy your videos anyway. They are always informative
You should try it.
Thanks for the video. I have looosened the caps with pliers instead of special tool. I was gentle and have not damaged the caps.
Good video and explanation!, I service motorcycle forks normally but just had a look before stripping my son's XCR forks for a clean and grease.
Excellent Video. With all the extras (helpful hints) thrown in.
Great video. Thanks RJ. I just finished overhauling my XCR forks. AAA+
Very helpful! Thanks. Just did my first fork cleanup!
Thanks for the great video I just used this as a guide to help service my forks. Thanks again
Tego właśnie szukałem 🙏
Thank you very much for your knowledge. I going to apply in my xcr suntour fork.
Thanks for this. I just cleaned and relubed the fork... wow what a difference. Now it almoust feel too squishy
As always. Thank You for a usefull lesson !!!
Nice demonstration 👍🔧
As usual. Very good. Informative
Thanks for sharing your knowledge.
Good video, it's probably about time for me to service my forks...
I feel confident about servicing my bikes fork thanks to this video.
This is very informative video on this kind of forks! I acquired one recently and wanted to do it myself as the brand has moved out of India. Good luck for more videos!
What kinda grease did you use?
Great video!! So simply yet brilliantly explained and guided, given me the confidence to do mine, Thanks again!! (Subscribed!)
Excellent clear instructions, thank you.
Great work man 👍
I'm going to go ahead and recommend Wira Hex Plus Allen keys/wrenches - I rounded a socketed bolt and hex plus got in there and undid the bolt. Wira (German) do SAE and Metric. The Wira's won't go deep though because coloured sleeves.
I mention this as your little key looks very well used. Tools = n+1
Had them for years, but they are still in great shape. Craftsman.
You have posted about 600 videos. Thank you for all of them (meh, even the car ones). So many people have benefited.
Gravel bikes/bike packing are making people look for "rack" and "no-rack" solutions. I did not find any on your channel. Maybe a video?
I am not sure what you mean? Rack/no rack?
@@RJTheBikeGuy Most racks are hub-and-frame-mounted. Surley bicycles (for one) has been installing many mount-points on new frames. Some riders carry their gear without racks or mount points (I do not know the names of their gear-carrying products). I thought you might have good insight for loading a bicycle for camping. Maybe this isn't a fix-it subject.
Brilliant video mate
thanks for this video. nicely done!
Thanks, very helpful and detailed. I'm gonna go service my fork tomorrow
Very informative, excellent video. Many thanks Tom Norton
Thank you soo much RJ for your kind explanation.. Its very helpful
Thanks
I'm from Myanmar.
You are my teacher.
What a great video! You have an excellent presentation skill! Muchas gracias!
it was very useful, thank you
Definitely useful and very helpful Mate.👍❤
Really helpful thanks bro appreciate it ❤️😂
Thanks for this and many more videos on servicing suspension folks. Just in the process of doing a restoration on my 20yr old personal GT MTB bike. All the best Andy
I saw that! What suspension does it have? The picture only had the frame.
You might like this. One of my old videos redoing the rear suspension on a GT LT-5.

My videos have gotten much better. LOL
Thanks for sharing, I've recently bought a used cannondale trial 7 2015 model, black with green and white stickers. It's a 29er. It's got the suntour xcr forks, no locker. They are very soft. I did think of swapping them out for a better fork but I have no idea what will fit. Thanks to your video I'm gona get a rebuild kit and see if I can stiffen them up and even add a lock out to them. I know it's a low spec bike but i feel it's a good place to begin
Great vid really helped me out 👍
Very informative . . Thank you brother.
So helpful mate thanks😁
You are a master, thanks for showing us how to fix bikes. I have my bike with a XR SunTour fork wich I have not used a lot maybe a 10 miles and the fork suddenly stopped working. I have never disassembled the fork nor tried to fix. I am guessing now that the fork has absorbed some water and is all rusty inside. I am going to try fixing now. I will let you know how it goes. Cheers from Ecuador.
A BIG THANKS, thanks your vid was a great help, cuz I bet I wud of broke something if it wasn't for your instructions. I was very surprised aswell, I've had my bike since 2016 and never serviced forks, they were full of water and even muck had cumulated on the left one, obviously broken seal. Thanks again mega help.
Thats right man. Me ayudaste mucho.
Thanks for this mate helped me big time great video :)
Nice video! I've been waiting for this one, although i was more curious on how the lockout on XCR really works. Also if you ride with it locked, is there a risk to break it if you run through pot holes and stuff?
I think it is hydraulic. Not sure how susceptible it is to breaking when locked out. You probably aren't going to break the hydraulic part.
Blow-off fuction will release the lock when front wheel hit on some hole realy hard.
Thanks Rj the bike guy for the sharing of knowledge.......I am Peter Angcon fom Philippines ,
Great vid' ! Thank you so much for sharing !
very detailed instructions
thanxs yor the best RJ
Hey RJ! Do you know what weight of oil the XCR air forks take? My manual doesn't specify what weight of oil to use, it just says (under the maintenance section) to use an oily cloth on the stanchions and dust seals.
Nice viedo ,,, sangat bermanfa at
Thanks, this looks lile my XCM
Thanks man im going to use this tutorial😊.
Very helpful many thanks
Thank you so much
Hey RJ, I was wondering could you ride without the lockout catrige? Basically just take it out and ride like that? Thanks a lot!
Probably not a good idea. It seems to offer some damping as well as has one of two bolts holding the flowers on.
thanks !really helpful
I take jumps with mine. It's nice to see what's going on in there. Really only one side has a spring and some mediocre dampening. The other adjustment just locks the other side.. Yikes! Then again, I haven't had and Sketchy moments so far. So just send it! 🤣
Hi RJ, your videos are great, and amazingly helpful. I’m wondering if you’ve ever worked on shocks from a circa 2009 diamondback response? The fork is spinner edge - 26”, 100mm travel. I have it apart, but it’s stiff, and some black plastic components dropped out before I could see how they lined up..😱 Cheers, -Howard
Same fork here, but I can't disassemble it. It's stuck as hell.. can you please describe step to step how you done it?
Thanks for sharing
Thanks it's useful
Have you shown how to do maintenance on a Trek 1000?
Thank you for your videos, they are great.
Maintenance is not bike specific. It comes down to the type of bike and components. So maintenance on a trek 1000 would be same thousands of if other roadbikes.
nice video bud !
Hi thanks for the perfectly explained videos on how to rebuild forks.
I have a set of these on my 8 year old daughters bike, is there any way of making them softer.
She did have a set of Marzocchi Z1 fligh lights, and I just reduced the air pressure for her weight, but the lowers have split?? I have no idea how she's managed that?
Back off the preload is about all you can do.
It was very helpful video thankyou very much sir
Very helpful, thank you. The rebound adjustment had me stumped until I watched this.
Thank for the lesson. Can I use lithium grease?
Really help full. Think brother Jajakkallha!
Quick question in your other video you showed you took out the seals and sleeve inserts! Did you do the same for this fork as well or you left them in
I’m going to do this to my xcr fork. Mine has been leaking though. Do you think this will fix it? I have heard people mention fork seals but I didn’t notice any in the video. Do you know what they might be referring to?
Thank you you help me a lot
So my XCR AIR LO 24 fork seems to have an issue. Even without any air in the air-side, it was still hard to compress. When I took it apart, I noticed the lockout mechanism seems to be air charged and is very hard to compress. The fork is barely used. Any idea? Do, I just have to replace the air mechanism?
Hello!
as you know many suntour and RST forks come with a lockout cartridge that you can replace if damaged, but there are some countries where getting a replacement whould be extremely expensive, i have both an SR Sountour XCR 28 with a lockout and an RST Blaze, they both need a new cartridge, can you make a video explaining how you can open them, clean the inside and replace the oil?
Cheers!
hi there im new to your channel and you have awesome videos and very informational for a newbie like me i bought a used mtb and honestly i have no idea what kind of fork i have but i managed to disassemble the fork and i think its a xcr fork like the one in the video but no idea what xcr model it is but my question is does a xcr fork have slider sleeves?
Great video, what do you think about teflon based bike grease, it s the only thing i managed to get my hands on in my area. Thanks alot, keep up the good work!
Shrug. I use grease meant for suspension forks. You are on your own with anything else.
Hi there, I have an old XCR fork that still works well and just needs service however it's got an issue, which is the brake mount is broken so I can't use it unless I decide to run with no front brakes. Is it possible to replace the entire lowers and if so are there shops that sells them?
I serviced mine following your video. Now I’ve put the forks back together, the lock out won’t tighten. The outer 5 mm goes round and round. I’ve tried stripping forks down again, no luck. What is stopping the lock out side from fastening? Help
Hey rj are you going to service any older dual crown crown forks?
I haven't had any bikes with them.
thank you
Very good 😊
Can I adjust the travel of my XCR coil? Please answer me thanksss
i have an XCM 30 which is not supposed to leak oil (because supposedly there is no oil inside it) but it does, and it's getting squeaky, do you have any advice? defo oil residue on one of the stanchions, but there shouldn't be any oil in that, should it?
Hi, great video.
My uppers and lowers are completely seized together and won’t budge at all! I’ve tried easing some lube down there but nothing seems to work?
Any suggestions?
Many thanks
No standard solution. You just have to work it. th-cam.com/video/d534ilYCaMk/w-d-xo.html
Hi! I like your videos. I have fork suntour NEX. It is a simple spring fork. Do you have video how to serve it?
Good luck!
Not familiar with that fork.
Thanks for the video, i just bought Epicon Front air fork and the suspension is too hard, any idea how to release the air to make it softer? big thanks!
Sorry, I don't know that fork.
There should be a cap on one side that says "air" and it twists off. There should be a schrader valve. Set the pressure so that your sag is 15-30% of the total travel.
hi.i have these forks which im going to do as you have done in the video.my fork caps have no adjustment.can i add adjustable caps for this fork,cheers
Thank youuuu!
Hey RJ! Love your videos! This one really helped me.
But I was wondering if the slider sleeve can be removed on this as well? I saw your XCM video and it had a sleeve inside the lowers that can easily be taken out, but looking at XCR it seems it has a different kind of sleeve. Mine looks similar to your XCR in this video.
I want to remove the sleeve because I want the lowers powder coated - and I suspect that plastic sleeve will just melt in the oven.
I think so. I can't remember for sure. Yes, remove any plastic!
@@RJTheBikeGuy any idea how? There's no notch like the XCM sleeve.
I have a xcr that has v-brake mounts but can't tell if they are m10 is 1.25 or 1.5 threads....
Dampening fluid likely in what you call the lockout cartridge right? How do you change the fluid? Dampening is way too slow on these forks.
