Thanks for doing this video. I really need to do some maintenance on my SR Suntour XCM 30 27.5's but I've been putting it off because I wasn't sure what to do. Thanks to you I do now :)
my sr suntour xcm fork is only 3 months old and orange coloured liquid started oozing out of the stanchions whenever it compressed, the next day, it had siezed up completely and didn't compress. I think this video will be very helpful. :^) thanks!
Thank you, if it was brand new then you bought it, it's weird, but that's probably rusty water, which needs to be removed as soon as possible from the lower.
The chrome on your fork when you took the shieth off you can get rid of with crushed up ball of tin foil and water it will bring it all off like new depends how bad it is on how long it takes shouldn't take that long though
Try with an L shape tool, like the allen key. There are gook and pick sets, which are meant for this type of work, but anything small and L shape should work. Or you can hit the other part of the lower with a rubber head hammer.
Without that you can't really remove it, try to ask for a tool from a bike shop, or order from amazon or Aliexpress, this way it takes a few weeks till you receive it, but than you will have the tool forever :)
Thanks, very helpful and helped me with my XCM fork. Question and a comment. Did you ever try to get the rust of off the stanchion leg, apart from using propyl alcohol? I've similar amount of rust on my stanchion legs and would like to remove it. Comment: I prefer to do the cleaning in a well ventilated site, otherwise the solvent fumes can be bad for your health. Advice: after cleaning the preload knob with propyl alcohol, mine almost seized up. I found lubing it with grease promptly after cleaning prevented it seizing. Thanks again.
Hi, I am happy to hear that you found it useful. I tried to get rid of the rust with vinegar as well, also tried a sandpaper with 800 hardness, but cant really remove it if it's in the steel, you can try to make it smaller, but it will grow bigger if you can not get rid of it completely with a sandpaper, but if you do so, the dirt would penetrate easier. Best thing you can do, to prevent it, by doing the maintenance regularly.
@@EatBuildRideRepair thanks, I used red wine vinegar at 6% solution, by soaking kitchen towel wrapped around the stanchion tubes and leaving overnight. It got rid of the rust ok. There's some slight discolouration in the tubes where the rust and wear had occurred. Its a secondhand bike, so still discovering what needs replacing. Yes, regular servicing should stop the rust before it starts:-)
@@driedmango123 try a small amount on paper towel and see what happens. My guess is no, it is the acid content of the vinegar which causes the etching action on the rust. I think white spirit is a solvent, not an acid, but open to correction
I need some advice got a suntour XC1 that looks almost identical to yours except it only got one spring, when i finish with cleaning process do i need to fill it with Hydraulic oil? thanks for your help and the video!
On the top of the legs you need to have a preload and or a rebound adjust knob. If you turn it CCW so the negative way it should be less bouncy, turn it inverse CW to make it more jerky. Do not recommend the second one, should be less bouncy to be usable on offroad.
Exactly today bought a new degreser, the one in the video. Even with continuous service of my two bikes, that bottle can be used for at least 1.5 years.
To be honest I know you know nothing about SUNTOUR XCM forks. It is a low end fork and it comes with USE AS LONG AS IT WORKS or AS LONG AS YOU MAINTAIN guarantee.
What a joke!!! Forks that rust in the rain??? I am not liking fork suspensions on bicycles. I just got my 1st bike with them, and I wish I had got a bike without fork suspension. I dislike the spongyness of forks on bicycles, and prefer a hard direct feeling and contact with the road, and it seems the materials are just crappy on bicycles. They are more trouble than they are worth. Regular forks = no maintenance and faster speed! 👍
You are right, a fix fork is a better option than a way more heavy and still not that soft working fork. However this one is a relative decent suspension, but it was left outside for a long time, so the coating of the stanchions dissappeared, and nowt it rusts even now, when is not even used just hanging on the wall. The water from the air damages anyways. Maybe I make another video about this.
same with brake disks i have owned motorbikes yes and push bikes don't need them they just add more weight and extra maintenance. more money for bike shops and manufacturers that make parts and we have to fix all the stuff that dosent need it and also buying more stupid tools.

Fantastic video! Straight to the point and easy to understand.
Thank you. I hope it helped you.
Thank you this was very useful. I am servicing a Suntour fork for a friend and it is in a bit of a mess
Nice video. @2:00, the black plastic cone on the end can be pulled off, to remove the assembly from the stanchion
Very beautiful and very easy to understand 👌

Yeah, thx for the fast explain.
I'm glad it was useful!
Thank you!
nice video thnx !

Was the fork slides of 28mm? Asking because of the wrench cap, there are 2 models bigger and smaller
Do you know the coil ratio of the fork?
My preload adjuster is not moving I can't preload my fork plz help me sir and also my lockout is not working
Thank you for the video! Where can I find the tool to unscrew the caps? No link in the description and can't find it online. Thank you very much!
Just search for the term "sr suntour key" on google and you'll find a lots of options, choose the store which is the closest to you.
You can make it on your own using CPVC or UPVC pipes. It will take about 15 min to make it.
My shock springs broke. Any leads where i can purchase this springs. I will appreciate
I think the safest way to take a photo of the serial number of the fork, and ask the local bike shop to order a spring for you.
Nice
how did you pull the springs out? can't get a grip with my fingers!
Try with an L shape tool, like the allen key. There are gook and pick sets, which are meant for this type of work, but anything small and L shape should work. Or you can hit the other part of the lower with a rubber head hammer.
@@EatBuildRideRepair that did it! Thank you for the quick response!
Idols
What can I do if I dont have that special plastic tool to remobe the adjuster?
Without that you can't really remove it, try to ask for a tool from a bike shop, or order from amazon or Aliexpress, this way it takes a few weeks till you receive it, but than you will have the tool forever :)
I made one myself from a piece of PVC-tubing 32x2,9mm, creating the crenelation with a drill, a hacksaw and a file

coke with aluminum foil works??
would white spirit work?
@@driedmango123 try a small amount on paper towel and see what happens. My guess is no, it is the acid content of the vinegar which causes the etching action on the rust. I think white spirit is a solvent, not an acid, but open to correction
Did it stop the squeak?
Yes, definitely. The rusty springs made the squeaking sound, if it clean and lubricated, it would be silent.
I have the same fork, but i don't know why its stuck, it doesnt move
try this service, it should move even if it's in bad condition. If it's completely rigid, there should be some major issue with the spring.
@@EatBuildRideRepair Thx a lot, i finally repaired my fork. The Problem was rust.
I need some advice got a suntour XC1 that looks almost identical to yours except it only got one spring, when i finish with cleaning process do i need to fill it with Hydraulic oil? thanks for your help and the video!
No but with grease
How to adjust the bounce of this kind of fork my friend?
On the top of the legs you need to have a preload and or a rebound adjust knob. If you turn it CCW so the negative way it should be less bouncy, turn it inverse CW to make it more jerky. Do not recommend the second one, should be less bouncy to be usable on offroad.
@@EatBuildRideRepair so where do i adjust my friend? Left preload or.right preload?
@@snow02brook83 the one on the left is the preload and the one on the right is the rebound
"I tried many brands and did not discover any difference between them apart from the price" Now that is sound advice.
Exactly today bought a new degreser, the one in the video. Even with continuous service of my two bikes, that bottle can be used for at least 1.5 years.
Tin foil help polish
Don’t use normal grease in forks, they will damage the rubber and plastic parts.
😮😮😮😮😮
To be honest, this fork should have been replaced allready...Rust and dirt on all parts :/
To be honest I know you know nothing about SUNTOUR XCM forks. It is a low end fork and it comes with USE AS LONG AS IT WORKS or AS LONG AS YOU MAINTAIN guarantee.
Does it make sense to spend any time on that rusty fork? Ok if it is for science's sake, then electroplate it to remove rust!
