Suntour XCR Fork Service - Disassemble/Clean/Lube/Re-assemble
Вставка
- Опубліковано 20 жов 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
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.
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 👍
Great video, didn’t realise my fork was so simple and straightforward, think one I can tackle myself. Thanks!
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 $40. 👍
Always good to see these videos in your library, very handy to have a reference should you come across them...
I’m not a mountain biker but I enjoy your videos anyway. They are always informative
You should try it.
Thank you RJ! I was scared to disassemble my fork suspension cause I'm afraid I might mess up something this tutorial of yours helps me a lot for future maintenance
Thank you! Just successfully repaired my XCR today. I had to wait for the wrench & grease which I bought online but once I had them, it was a breeze. BTW, mine didn't have the lockout. Both just had the same pre-load dial.
Good video, very straight forward and informative. But there are two things to point out
You should not use a metal hammer to tap on the screws at the bottom of the lower or you risk damaging the dropouts, and make sure to remove any preload from the coil before dissasembly/assembley. Thank you for another video.
Thanks so much for this detailed explanation and tutorial! Exactly what I needed to know for the maintenance on a bike that I bought for 20$ on eBay. Take care and stay healthy 🖖💪👍🌞
Great job, RJ!
I've just come by these forks, 2006 I think, so will be following your plan! 👍🏻
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.
Thanks for the video. I have looosened the caps with pliers instead of special tool. I was gentle and have not damaged the caps.
Thanks for the great video I just used this as a guide to help service my forks. Thanks again
Great video. Thanks RJ. I just finished overhauling my XCR forks. AAA+
Excellent Video. With all the extras (helpful hints) thrown in.
Good video, it's probably about time for me to service my forks...
Great video!! So simply yet brilliantly explained and guided, given me the confidence to do mine, Thanks again!! (Subscribed!)
I feel confident about servicing my bikes fork thanks to this video.
Very helpful! Thanks. Just did my first fork cleanup!
Thanks, very helpful and detailed. I'm gonna go service my fork tomorrow
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?
Thank you very much for your knowledge. I going to apply in my xcr suntour fork.
Thank you soo much RJ for your kind explanation.. Its very helpful
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.
Very informative, excellent video. Many thanks Tom Norton
What a great video! You have an excellent presentation skill! Muchas gracias!
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.
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
Thanks
I'm from Myanmar.
You are my teacher.
Thanks for this. I just cleaned and relubed the fork... wow what a difference. Now it almoust feel too squishy
Nice demonstration 👍🔧
As always. Thank You for a usefull lesson !!!
As usual. Very good. Informative
Excellent clear instructions, thank you.
Brilliant video mate
Definitely useful and very helpful Mate.👍❤
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.
Thanks for this mate helped me big time great video :)
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.
Great vid' ! Thank you so much for sharing !
Great work man 👍
Thanks Rj the bike guy for the sharing of knowledge.......I am Peter Angcon fom Philippines ,
Great vid really helped me out 👍
thanks for this video. nicely done!
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.

Very helpful many thanks
it was very useful, thank you
So helpful mate thanks😁
Thank you you help me a lot
nice video bud !
Thats right man. Me ayudaste mucho.
thanxs yor the best RJ
Very helpful, thank you. The rebound adjustment had me stumped until I watched this.
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.
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.
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! 🤣
Thanks for sharing
Very good 😊
Awesome I took it to a bike mechanic before watching this video the mechanic told me I had to replace the complete forks he couldn't fix it the shocks we're not locking up after i try to lubed then up I came across your video and problem fixed thanks so much here american in Indonesia
overproud lu
Thank for the lesson. Can I use lithium grease?
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?
thanks !really helpful
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!
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.
Pls make video how to adjust the travel of xcr suntour coil fork thanks in advance.
hi I need to see the fork maintenance SR Suntour XCT 30, helical spring, preload, hydraulic block, 51mm offset for 29 "wheel, 100mm QR, 100mm excursion. I don't understand much English but your videos are very useful for me to see them. I appreciate very much what you do
I don't have a video for that. Haven't worked on one.
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.
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?
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.
Hi! I support you when you restore that's bike from the past..i liked very much! My XCR fork sr santoue 26 inch lockout is very stuck how can you help me with that???
It's a great video, don't get me wrong, I love it and it was a great help and i rebuilt my Fork and works great.
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. ua-cam.com/video/d534ilYCaMk/v-deo.html
Thanks for the video, I managed to service my XCR fork. Unfortunately, my seal on my LO cartridge is broken, a lot of oil come out from the cartridge. Is there any way to fix the cartridge and change the seal? I will be waiting for your fix if it is fixable. Thanks RJ. GBU.
I do not know. You might need to replace.
Great video.... but I hate my XCR! Gets so stiff when cold outside... guess I will have to upgrade sooner than I wanted.
Snaab92 dude I have the same problem after a year . Thinking of buying some fork lube
@@joelrivera8758 I am going to try some silicone spray on the stanchions... I hear that may help though I find it performs fair in warm weather.
Thank you so much
Thanks it's useful
thank you
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.
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.
very nice 😍🤩❤
Hi there. Many thanks for tutorial. All sorted but my mcr is slightly different as in it only has 2 plastic dials on the top, no blue lever. Put all back together but is now permanently bouncy. No lockout or anything. ???????
There are a bunch of different versions of these Suntour forks.
Hey rj are you going to service any older dual crown crown forks?
I haven't had any bikes with them.
Just subscribed! Awesome channel dude this video will help me shortly. Just one thing, i have a lock-out switch on my forks to switch them from the handlebars, will it be the same process as this? With a cable through it will i still be able to just "pop it off?"?? If you see this and can get back to me/help me, it'd be much appreciated! Maximum respect dude
Can I adjust the travel of my XCR coil? Please answer me thanksss
Thanks for your video, it is very handy. My fork is not going smooth because of the seals or sleeves, do you know if these sleeves are also removable as you showed for the XCM fork :)?
They probably are.
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
