Just in the right time! Im just about to change the seals of my KTM which has WP forks. Thanks so much!
Sweet vid !! Excellent presentation, and VERY clear instructions !! Wonderful to hear from an expert. Thank you !!!
Dustin - excellent job on this. I just did the forks on my 530EXC and followed you step by step. Thanks much.
Nice work! We're glad the video helped you tackle the job.
This is the reason always buy my parts from rocky mountain
Great video thanks. My preload adjusters didn't unwind the cap just came off in one but it hasn't effected anything. I also got away without any special tools (insulation tape to drive the fork seals and protect the seals over the bushing recess and drilled an old spanner with 4mm holes and used the drill bits to unwind the top cap) I used 600ml of oil in each fork leg (2010 ktm exc) and forks feels brilliant now 👌
Great job - lots of detail clearly presented and no time wasting!
To what you're calling "dampening", I believe the technical term is damping.
Totally agree, I get told off when I say dampening.
@@dannyrose5576
😂 You can *damp* an oscillation, and *dampen* a towel.
Great vid! Need to service my forks over the winter and would like to DIY it. This vid explains it perfectly. Links to the tools like the fork driver, bullet etc would be great.
superb vid rebuilt my forks in half the time it would of taken after watching this.
Thank you for this!! Just ordered all the parts I need to do it!
Awesome, glad the video helped out! Thank you!
Couple of comments. Lower end thread cap screw. It works better if you start the cap off with the forks still assembled. Only a couple threads. If it hangs up later on... put the fork spring in, push down on it so it bottoms in the tube, and the threaded portion will come off.
Snap ring holding the fork oil seal in.
One end is notched and will come off. Other end isn't notched and won't come off !
Hi,
I'm a Portuguese fan of your channel. Lots of practical technical information, and very well explained.
I have a KTM exc 450 from 2005, and I did this oil and seal change operation, without disassembling the fork base, just removed the spring, emptied the oil, cleaned it and filled it with new oil and seals. At the end of one of the forks, the clicker always rotates without stopping. I am going to address this problem but in the meantime I would like some opinion of yours about what I have done wrong, and possible damage that I have to pay attention to.
BTW, is there any video of changing the glass oil level check thing on these bikes? I have a smal leak there...
Thank you in advance, for your attention.
Come to Portugal for an adventure ride, i will show you guys the best trails.
Thanks so much for the vid! Just wondering if it's necessary to remove the reboundand compression assembly or if it's possible to change seals without taking it out. Thanks!
HI! What is mandatory to replace ? only the oil seal and the dust seal?thank you for the vídeo great introctions.
Question please - if just changing seals is it ok to leave damping assembly and compression adjuster in place?
Thank you great video helped me out alot
Could you explain to me how to remove the cap from the bottom of the fork and put it back on?
I have the fork just like this and I can not remove the bottom cap of vuleltas inside and it does not loosen.
do you have yo remove the fork damping rod to change the seal?
do you have to remove the damping rod to replace fork seals?
Hi me from Indonesia I really like your vidio😊
Hi! I own a 990 SM, is that the same kind of forks ?
Very precise 👍
Thanks 😊
nice tutorials bro!👍
Brilliant thank you
Great Job...
I know this is old, but I have just rebuilt a set of 2004 forks and they have 3 bushings and a large spacer. I have heard to remove stiction, you have to remove a bushing and the spacer. But which bushing ? The middle one ?
Adventure 1190 electronic fork rebuild would be a nice video :-)
Hi, thanks for the video!...which are the benefits of the fork seal grease? does not pollute the internal fork oil?? can we use normal grease or lithium grease?
When cycling my damping rod to remove air...on the right rebound side I get nice full stroke damping, while on left compression fork I only get damping fir the first few inches. I gather from other sites that this is normal...can you comment? 2018 250 EXC-F with no preload adjustment.
That’s what comes on n the 2016 350 sxf right cam I take the top cap off and put oil into n top do I have to take fork off and fill in bottom ? Thanks
Do I need the thin 22mm wrench to do this?
The forks on my dirt bike are inverted. Can't I replace the seals with them on the bike?
Hey Dustin dude! Whats the cheapest fix for wp aer forks? 22 ktm 350sxf
Is the process the same on the wp43 omthat came on the 2002 model ktm?
good vid can u do one on how to replace fork seals on a fork similar to a 2008 yz 250f if u haven't already. ps most helpful videos out thanks for the services you provide.
Sure do! Check out our suspension playlist: th-cam.com/video/G0dLM_IoIOQ/w-d-xo.html
We appreciate you watching. Thanks
thank you for your help I appreciate it
Is it different with the showa forks or is it kinda same?
Why remove the compression fitting on the bottom?
Hello I have an '08 sxf 250 European could you please tell me the capacity of the forks on mls (metric)!!!! Thanks
Hi... can you make a rebuild video of WP suspension 4860 ROTA SPLIT with EDS?
How much fork oil it takes in ml the fork pls
How to get the spring out and even more important, get it back in if it is rockhard?
Eat a few eggs every morning and workout a little
is it safe to rotate the upper tubes on the forks 90 degrees when the forks are installed on the bike, for example to reorientate the facing of the protective stickers?
Yes, you can do that no problem.
What steps are necessary if I'm only changing the fork oil? Can I just remove the top spanner cap, dump and refill or do I need to back out all adjusters as per video? Thanks
Yep, just remove the top cap and dump it out. Not need to back out your clickers for that.
That's what I figured but thought I'd ask. Thanks for the fast response!
nice vid
These forks remind me of the old 2004 yz250 forks.
Anyone know of a video that shows how to disassemble the forks off a 2014 ktm 300xc? Thought this was it but I don’t have an adjustment on the bottom of my forks just a big Allen bolt
I believe your bike has the 4CS forks on it. Check out this video and see if this looks more familiar: th-cam.com/video/xzn6K8qywQM/w-d-xo.html
Hopefully this helps!
Can we use a fork oil level syringe on this style of fork? Would that be more accurate than measuring the oil volume? What would be a recommended oil level?
Yeah I'm confused why he didn't do that. Or bleed the air out
kris nowak I'm guessing that he looked in the manual and it had the volume of oil that you should put in each fork.
Hi guys! What tipe of suspension grease do you use? I canot find anywhere the KTM recomended grease and i am lookibg for a replace. Can you tell me the type that you are using? Or maybe the properties that the grease should have?
IN this video used the pro circuit grease. Race Tech also makes a for grease. Both will work fine for any fork.
@@rmatvmc thank you very much. I hope i can find in Roumania Pro Circuit grease, but i'm guessing that any type of good quality Seal and Oring grease should be fine. I apreciate a lot your videos , i think they are great! Thank you very much both for the quick answear and for the good videos that you make. Have a good day!
@@AdhD311 You bet! Thanks for watching from clear over there. And yes, there are many greases that will work. I use the bel ray waterproof grease we sell and it works great. Have fun out there!-Chase
@@AdhD311 I was going to comment on the "fork seal grease" while I appreciate the video very much anyone doing this should know that grease for rubber/orings will work as it wont have any strong properties to harm the rubber parts. Trying to sell grease is more money for RM and I understand but I would think everyone is going to buy the seals, oil, etc anyway and probably a few of the tools and a few are not absolutely needed.
That being said they want to make money but buying "fork seal grease" is a bit much of a push when many people will take it at that exact word, and you could of easily changed your wording. Again make the money but "Come on Man" easy with it.
Why do you want to coat the inside of dust seal with grease, wouldn't it smear grease over the inner tube and then catch dust afterward, and also please tell specifically which fork greade do you use
Why he coated it in grease was so it was easier to install
Question please - when you screw the top cap back on, is it until the first slight resistance or screw it until it stops home? cheers!
Could you give us a time stamp in the video please so we're on the same page?
@@rmatvmc 12.43
I screw it down and feel a little resistance. I can screw more until it stops hard.
@@joncavalier8875 You'll want to snug it down until it's all the way home.
@@rmatvmc thanks didn't want to overdo it.
I didn't, and the rebound clicker just spins. Thanks for the reply!
@@joncavalier8875 you bet! have fun out there.
Very nice and helpful video! :-)
But I have one question: Do you have to remove the compression dampening fitting and pull the cartridge out, or can you leave it in as well? Does it matter when I am only replacing the fork seals?
No you don't have to take the cartridge out to replace the fork seals
Hello my cartridge is always spinning so i cant use a Torquewrench. With the impact wrench it is possible. Any tips?
Put the spring back in and top cap then try using torque wrench
Great video. Lots of great info. It’s damping rod. Not dampening rod. Damping means resistance to movement. Increase compression damping and your increasing resistance to compress. To dampen is to make something wet. Just sayin
*Chris King* - Thanks.
Chris King ......I think the video was about fork maintenance, not an English grammar lesson. I guess being ever so perfect makes you feel superior to the rest of us mortals. This was an incredibly useful, instructional video and deserves praise not juvenile criticism or totally unnecessary comments. Go lie down for a long time and give us all a break.
Richard Clare now you know why he’s King
Would my 2009 ktm xcw 200 have the same forks? And if so how much oil do I put in them? I can't find this information anywhere and I can't find a shop manuel anywhere that I can buy. Thanks!
Yes, my exc200 has these forks. You need to measure the oil in mm.
@@thomas5395 Thanks!
Can you tell me the for seal size
Can i buy the as usd
A bicycle repair stand works great instead of a vise. Holds the fork tubes carefully.
Thanks Phil i was wondering what i could use
Thanks Phil i was wondering what i could use
Hello my Spring Preload is locked what should be done to fix it?
It might be backed out all the way, try winding it in.
I got my bottom bolt off but now putting it back on it just keeps spinning!!! what is supposed to hold it and stop the cartridge tube from spinning?
Try pressing the piston rod slightly to the side. -Charles
@@rmatvmc hey that works to a certain point but cannont get any where near the recommended torque before it starts spinning ..
Is it possible to do a poor man's oil change on these?
Open the cap, unscrew and remove the spring, dump the oil, refill the same amount and install the spring back?
just a heads up for everyone with these specific forks dont use an impact on the bottom compression assembly or atleast be very careful i used just a regular makita battery impact driver to zip mine on and i must have went overboard the first one went on fine, so i thought..... then the second one completely sheared off the aluminum collar on the assembly causing it to push right through into the fork totally ruined have to buy 2 new ones now, the first one didnt shear off but cracked around the entire edge and is barely hanging in there terrible design to make it out of aluminum they are not cheap either so when my new ones come i dont think im going to use an imact at all dont want to risk it
Jeez, what a pain. Thanks for letting us know about that, I hope you have better luck with your new ones!
@@rmatvmc thanks for the reply yea hopefully I can save some people some trouble luckily found 2 used compression assemblys on Ebay for 39 a piece this time I will probably just use a drill to get it started then finish with my torque wrench
@@@psyfertech did you have any issues with torquing down the bottom compression fitting? mine just spin, I can't put the correct torque on them...
@@adamk7630 yes it was pretty tricky to get that thing to bite what i found helped is get it in most of the way and take your hand and kind of smack your wrench to give it kind of an impact or jolt that was able to get mine to bite and then i was able to get the torque on it but like i said above dont try an impact you run a high risk of ruining that compression assembly the aluminum collar is a massive weak point where the crush washer sits on
Sir can i buy the all tools???
Yes, the first link in the description will take you to a page with all the parts and tools used in this video.
@@rmatvmc you have number whatsApp sir???
Air impact on the compression adjuster? Don't do this. If the cartridge is turning put the spring in and cap on temporarily and compress the fork a bit while tightening the adjuster.
tried that but it still keeps spinning 😢😢
check for thread damage, you should be able to easily thread the parts together
why does the buttom just spin
You may need to use an impact to loosen the compression damping fitting on the bottom of the fork. Starting at 4:50 we show that process.
@@rmatvmc yeah i saw that thanks, i tried with a Normal drill but it didnt come loose, i dont understand how the threads dont catch, anyway i replaced the forkseals without removing that bottom part.
This is why don’t have Kym it’s a joke how to do them
1,13 once? Are u sure?
21.13 fluid ounces. This amount will vary depending on you and your specific motorcycle.
