Thanks Rocky mountian, for these videos rebuilding my air forks couldn't figure out torque my KTM manual had nothing on air chamber torque or grease to use on failed seal.Updated mine to 2018 better seal .Really a good thing your doing with these videos.
On heating the chamber, I had to heat mine to a point there it melted the seal inside the valve. The seal is not available by itself, so I had to buy a new valve which costs around $100. The new valve comes with red loctite already applied, so I removed it with a wire brush so I won't have to buy another one the next time I service the fork.
Hello,great video,can you help me with harsh suspension on ktm 250 sxf 2016(aer 48 fork),I’ve tried with exact positioning of both forks and same result,after driving,I’m dead,my hands hardly feel 😁,but I’m beginner,I thought I’m out of shape for this kind of sport,but when I looked on my friends bike,my suspension is much harder,so what can be be the issue?
If you heat them with a torch, rebuild the seal head and use Centoplex grease on the main seal and underneath the seal on the walls of the cartridge. I would never use any other grease besides ktm centoplex.
I need to replace my Shrader valve, and I was wondering if it was okay to let all the air out if you are not going to replace anything in the air chamber?
the pre-applied loctite is DESIGNED to be installed dry. it's the same stuff that required you to break out the blowtorch in the first place; it works!
So basically WP XACT forks with AER technology have damping functions on the right side and air on the left, i understand the left side(air side) but is the damping side like coil spring or is it just damper, spring, oil or is it damper and air or smh?
Thanks for bringing this up. www.rockymountainatvmc.com/oem-schematic/3 #26 and #11 on the diagram for our 2018 450 SX-F, should be the same, but double check for your bike. -Charles
Is there a rebuild parts list or better a kit to get everything needed to do this rebuild? Looking at the KTM OEM schematic or parts finder is confusing.
There is a WP Inner-Chamber Seal Kit that should make it a bit easier. You can click the link in the video description to see that and other tools we used in this video. The rest of the parts you may need will have to be from the OEM parts finder though.
Hi, What are the part numbers for the upper and lower seal assemblies? I'm struggling to pick out the correct parts in the oem parts schematic. Looking at the 2017 ktm 450 sxf schematic, I believe they are parts 7 and 24 but unsure if 11 is the lower instead. Thanks!
Yes, for your bike It should be #24 and #11 on the diagram, but the the numbers can change from year to year. For example, our 2018 KTM 450 sxf was #26 and #11. Just look for the two pieces that sandwich the top-out spring. I know this is too late for you, but hopefully it can help someone else. -Charles
What are the part descriptions for the upper & lower seal assemblies? I saw the same question for a different bike. Unfortunately, the parts diagrams are a little confusing. I have a 2017 Husqvarna FC250. Would it be #10 screw sleeve oil cpl & #14 piston set air fork?
Or #11 & #24? Screw sleeve m35… & x-ring? I asked one of your parts specialists via chat, and they felt that the seal kit would include everything with a # on the OEM diagram. Is that true?
I have the same forks, the wp aer 48 forks. I replaced the the fork seals on my right fork and after I was done I noticed its a lot easier to compress the fork together then it is on the left side. Is this how it’s suppose to be?
What are the part numbers for the parts on the left shown in 1:52 of the video? Are there any serviceable rings on those parts, or do you need to buy them complete if your forks are having any issues? Once I let the air out of my fork, it went into full compression under strong suction. The forks were working fine as far as I can tell before servicing. I just want to make sure I have the correct parts replaced. Can anyone chime in?
@@stevetdesigns For my 19 FX450, I ordered and received both. The bottom is a "Screw sleeve M35,5x0,8 cpl." - Part # 48602138S2 (#11 on OEM parts finder), while the top (Blue Band) is a "Piston 34x35,4 mainpiston Freudenb cpl." - Part # 48601628S (#26 on OEM Parts finder). I decided not to change either after getting into the inner chamber. A guy on another forum said that some amount of suction is normal. At least I have the seals and know-how to change it if needed.
