Although this is lil old just did my right fork on my 2015 crf250r which has the sff fork and the right one is just oil and it was a lot easier than I though thanks to you guys.
Great video. Question for you. How much oil goes into the inner chamber? I should have 340cc but I’m a little confused, should 340cc be the total for the whole shock, inner/outer combined or just the outer part. If 340cc is the outer part only how much goes into the inner chamber? I cannot find anything online for the specs and do not have a manual. Thanks
when i install the inner cap i hear air is coming out. is that normal ? Got the Showa 47mm from a Drz 400sm. the manual says there is coming in 182ml oil in it .
will it work if I loosen the bottom bolt on the fork and take the whole cartridge out to change seals? I dont have spring compressor to take fork cap off...plus don't u have to set the preload or rebound settings before u start
Salut , je viens vers vous pour savoir la quantité à mettre dans le bas de fourche ? Et dans la cartouche avec la seringue combien de centimètres s’il vous plaît ?
I dont even know if you guys respond to videos this old but is it normal for the left side to not return to full height once all back together? I just did both forks (ive never owned sff forks before) and the damper rod was smooth and returned to its normal position fine. but once all together, when i set the fork on its own weight on the ground it sinks a bit compared to the spring side. Is this normal because the spring is on the other side or is something wrong?
Don't worry about that. Some manuals will give a measurement for the length of the inner fork tube with everything assembled and the fork fullly extended. You can check that to make sure the fork is assembled correctly. The only thing holding that fork up with it sitting on it's own weight is air pressure that should be set at atmospheric pressure when fully extended, and only ramps up as the fork is compressed. -Charles
Someone help me! Just did my fork seals on my left fork and it's REALLY soft compared to the right fork. Is that a normal thing since theres no spring in it? I even went to replace oil in the inner cartriage and outer chamber...i cant figure out for the life of me whats going on? Any tips?
Is anyone else having trouble moving the forks up in the triple clamps, my right fork won’t move up, I think it might have something to do with the fact that that one doesn’t have rebound
does any one know how many clicker setting on the rebound for the 2013 kx250f and it says in the manual 20 +- 4 now im little worried becuase my rod is stuck in the valve portion of the fork but yet my clickers still go 16 out and 16 in. should i be worried
You can do it that way. It just get's pretty messy with all the oil that comes out of the bleed holes. But if you don't have the gauge, then that's you're best bet. Just make sure you put your hand around the holes when you slide the inner cartridge back in. This is the method used in our showa 49mm fork rebuild video.
can some one please tell me what the inner is and outer on the forks on a 2014 rmz450 I have looked everywhere please rocky Mountain I've even called rg3 and they just told me the outer was 300cc I need help please what is the fork oil height for the inner and outer
So the guy made a big mistake as far as explaining the cylinder unit oil height and valve assembly, for a showa sff fork the rod has to be fully out out to check height (obviously after u purge out the air) anyway after that the valve assembly goes in. rod has to be pushed in and let out about .79 inchs or 20mm then u should be good to install valve assembly, goofball dosent mention Any of this in the video which is a big step in my opinion as the oil height various depending on where the rod sits and having in the correct spot makes it easier to install valve and if u go and call their number they have no idea what ur talking about luckily I found manuel online explaining the cylinder unit as mine does not only outer tube hope this helps anyone not bashing this guy but u left out a important part leaving me confused and guessing
hi, i'm tryng to replace seals on my suzuki rm 125 2008... i have showa forks. i did everything u said, now i have to separate fork tubes. but they wont come out. i heated with a heat gun (an electric one) but nothing, they remain togheter. i alredy removed dust seal and the metal ring. what can i do for separate fork tubes?
federico moroni Those fork tubes should come apart if you have already removed the retaining ring. In some cases I have seen the seal almost weld itself to the outer tube in a sense, and what that does it causes the outer bushing to force itself up onto the inner bushing when you slide the forks apart causing the forks to basically jam themselves together. This makes it very difficult to separate the forks tubes so you are on the right track in applying heat. I would try giving it a little more heat and also some sort of lube up in there to see if the seal will pop loose. You basically just have to keep trying as there really isn't any other way to separate them without damaging expensive components. Try what you can and if you still have troubles you are welcome to call in and talk to me and I can try and help talk you through it. Ask to speak to a Tech or me (Wes) @ 1-800-336-5437
Rocky Mountain ATV MC ok tank you very much for your support. tomorrow i will try to give more heat and put some lube in the tubes... i hope it will work. just a last question. for retainig ring do u mean the metal ring up on the dust seal?
federico moroni Nice work! Those can be a bear sometimes so it's good to hear that you got it apart nicely. If you run into any other questions feel free to let us know!
hi guys, i have another trouble with the inner cartridge oil change. i take off the cap, i drain old oil, i let the fork upsidedown for some time. then i put the new oil (180ml as the manual say), i make the air come out pushing and pulling several times the inner tube and last i close the cap back with the inner tube completley extended. the problem is now; when i push the inner tube it wont come out completely extended. it come out for 4 or 5 cm than it stops. and if i try to pull it out it returns inside as if there is vacuum inside. what i should do? tanks.
federico moroni Sorry to hear of your troubles. Your bike is equipped with the dual chamber forks so I would refer to our Dual Chamber Fork Rebuild videos to begin. Here is a link to the first video Fork seals, change on motorcycle part 1 (of 2), twin chamber . It sounds like one of your inner cartridge seals might be leaking. You have a seal below on the damper rod and one up top with your free piston. Is this happening on both forks or is it just one of them? If you've already tried bleeding the inner cartridge multiple times with no luck, replacing these seals would be my next recommendation.
We recommend you go off of what your service manual specifies for you year, make and model. From what i've researched, your measurements that you list match up. 350cc's and 150cc's inner.
Rocky Mountain ATV MC So I used this video and the tools you suggested. The video is very accurate. No issues. I replaced the bushing and seals. The noise I was hearing was the base valve spring. Thank you for this great video.
if you go to race tech's website and do a search for your spring rate and everything it will tell you how much oil to put in each. or try looking up your owners manual.
+Brittany Nelson You've separated the outer tube from the inner tube already correct? Or are you at that point? Following the steps in this video should help you complete the job.. let me know what step you are on and we'll go from there!
+Rocky Mountain ATV MC Thanks for getting back to me. I ended up using a heat gun to the outer tube and a door trim tool to pry the oil seal out. All good now and back together. Great video!
Bueno, depende con cada modelo de bika.. recomendamos que chequee tu manual. Va a necesitar buscar la medida por tu propia motocicleta. O si quieres, me dices la marca, model y ano y te lo busco?
Rocky Mountain ATV MC tengo una honda CB 600F del 2007 y voy a cambiar retenes de horquilla y aceite hidráulico, me podrías decir que cantidad de aceite hidráulico lleva cada barra?, me sería de gran ayuda, muchas gracias, mi correo es, gregovero@gmail.com
Gregorio Bizcocho En el manual lo dice asi que con cada barra pide una medida de 4" pulgadas desde la parte superior del tubo. Significando que el nivel del aceite alcanza la medida de 4"
