How To: KTM DIY Shock Rebuild With Basic Tools - 2023 2024 KTM 300 XC TBI

- This shock rebuild was on a 2023/2024 KTM 300 XC TBI with an XACT shock. The procedure will be very similar for all modern KTM bikes.

Thanks for sharing man. I just got the bleeder cup and SDI bladder kit. I have the vac pump and all that but think I'm just going to use the bleeder cup.
Nice! Good luck, nice having the tools👍
Lovely video! Now let's have home revalving video haha
I might have to nerd out researching for a lot longer for that to happen!🤣
FYI for the PDS shock owners. The plastic spring preload collar will not; repeat WILL NOT fit over the clevis once its back together. I ended up having to cut mine and stretch it over. Once clamped in place its fine but its easy to miss that detail.
Great video tho. I've added it to my other suspension rebuild vids! 🤘
Fantastic video! You've made it clear at each step. Makes me want to invest in the extra tools to be able to service the shock myself.
Bladder does smooth out the sharp stuff for sure! Great video.
Nice straightforward real world video and no music! Yay!
The bleeder cup is slick, I need to get one of those. True 3rd world oriented cheapskates can simply use their high pressure air fork pump to refill the shock reservoir with air, which is 78% nitrogen. I may or may not have done this 😂
Using ambient air from a small high pressure pump is not an ideal thing to do, but truly not the end of the world either, especially if one lives in a dry climate. The biggest reason to use pure nitrogen is it is perfectly dry.
Since I have both I’m going to try just air and see if I notice the difference I’ll bet I won’t!
@ 9:35, you say "torque to 29NM or 40Ft-Lbs". I think it's supposed to be 29Ft-Lbs or 40NM. Great video. Thank you!
Appreciate this video very much.
Very Good Video.
Great video. Definitely a lot going on in there
Few weeks ago i almost did this same. I took apart everything but i couldnt get the needle fast enough so i just put it back together and send it to a shop. Maybe i will do it next time and order all parts before my shock blows up and i must service it. Great video!
Interesting, like you couldn’t get the needle out quickly?
@@TechEnduro No, i needed that nitrogen needle and it would have taken weeks to get it here in finland.
Hey, great video you definitely made it look easy,.. Cheers!
Great video! Where did you get the wp bladder from?
I got it from BFDMOTO.COM they are based in Canada but most suspension tuners that deal with WP can order it. Also Ktech and and others make them, I like the wp one because it has a Schrader valve.
@@TechEnduro thanks!
Hello! What is the part number for bleeder kit WP?
Link is in the description
WP634-8086
nice! So in the longer run was the difference bladder/piston worth it? I’m reluctant re the bladder because it means more maintenance. Especially if the difference is not that noticeable.
it’s a small difference, I like it cause of the small performance change but also for the ease of maintenance with the schrader valve there. I’d still do it again, but only when you’re ready to do a regular service.
@@TechEnduro thanks. I like regular service, but I’ve never touched a shock because I don’t have the tools. I want to do the 6500 cartridge for the forks, but think I’ll leave the shock stock…
Great video! Take your nice coat off before though :)
🤣 unfortunately last year I ruined this nice jacket during a mini spray foam explosion!
Whats part number of the blader kit?
WP Pro Bladder Kit Link 2023+ Part # ZF10011
You should be able to order it from your dealer too
Plenty do not bother with nitrogen with bladder kits as there is more air volume.
I’m going to test it with just air and see if I notice a difference, my guess is I won’t.
@@TechEnduro that was great! did not know WP shocks are kinda self serviceable.
I am mainly not a moto guy fwiw, but in MTB applications we usually do not bother with pure Nitrogen anymore for about 10 years now and just use atmospheric air with no downsides. also pressurizing usually happens through regular tire core valves (on mtb shocks usual IFP/bladder pressure is ~160-200 psi) which clearly eases the damper service.
when not using a vacuum pump to bleed, to help with countering the chance of cavitation, I think it is a good thing to try to dissolve as much gas as possible from the oil before filling the damper by decrompessing the oil in a syringe. heating up the oil in a pot might also work for that matter.
Ok job . I know you left out a few things /safety wise.we all have to start somewhere.
Yup. First time👍
@@TechEnduro I started 1986
Bigger question is why?… oil looks fine, nothing appears to be leaking…aside from the addition of the bladder kit…seems wasteful considering 90%+ of KTMs sold will never be raced let alone by a accomplished racer that using will use A Kit parts…
Mainly because I enjoy learning about maintenance. I also just do it at a normal interval to avoid a surprise that might ruin my ride. Necessary probably not, but I’d personally rather find clean fluid and no issues when I pull it apart vs a mess👍
same here I race 2 series and I have learned that if the suspension is serviced regularly my bike stays consistent@@TechEnduro
50 hours you should change the oil as you will start to wear the cylinder out. Very important for longevity of shock consistency. Although you don't need to change seals needlessly.
My suggestion would of been if you’re going thru all the trouble to service the shock, to also remove the lower shock swing arm linkage and clean and grease those bearings/bushings.
@@GNX157indeed. I did that, good call.
