Never in the world I would have thought that this would be so easy and fast. Thanks a lot
You're welcome!
is this sarcasmn?
Nice video. Concise and to the point not over explaining stuff to people that can't hold a hammer (and shouldn't be attempting to service their very expensive fork in the first place), and thanks for making the video showing air sleeve service.
Thanks for the feedback! Really appreciate your positive comment!
Thanks so much for this video!! It is the one I watched when yesterday I did my first fork service, very concise and to the point and also now I finally understand what a damper service does :) Took me about 4 hours since I was triple checking everything, but next time will probably be half the time. I will add, for me the hardest part was removing the cap from the damper - it would just turn in the vice no matter how hard I clamped. I solved it by using carbon paste and in addition warming up the area of the thread to loosen the locktite.
Glad to have helped you successfully complete your first fork service! Nice work with the carbon paste/ heating - next time you could also try spraying the damper body and vice with Alcohol and clamping while still wet….
Great work mate! I've ordered some tools and will tackle this myself with the help of this video. 👍
Great to hear!
Great video! Very clear and super useful. Thanks!
Thanks, happy to hear!
Excellent video! Thanks!
Glad you liked it!
Thank you for that good instruction video. Glad I found the pedro tire lever ..its ordered 😎
Glad it helped!
Great video!
Thanks! Let me know if I can make some other videos which would be helpful for you!
Very good video, thank you.
Glad you liked it! 👍 Let me know what my next video should show!
@@mtbsuspensiontech I would greatly appreciate a GRIP2 VVC damper rebuild video. I have the photos and write up, but a detailed video would be fantastic.
Super vidéo ❤
Thank you!
amazing man, tks. LIKE N' SUBSCRIBED
Thanks man!
Hi, before remove compression (and rebound) adjusters, i have to fully close or fully open them? Can't find this info, maybe it doesn't matter? Thank you for the answer!
Very interesting and well done video. I only have one question about the GRIP2 service: the official FOX video (like other tutorials) indicates to push the cartridge rod upwards for 3/4 of its travel in order to release the excess oil. In other videos some don't. By pushing the rod up so much, wouldn't you risk letting too much oil escape from the cartridge? However, I suppose it is used to avoid adding oil to the 40cc PTFE already included in the FOX reference table. Thank you so much! K
I agree that pushing the shaft 3/4 of the way risks removing too much oil from the cartridge.
I‘d rather have a few more ml of oil in the lowers than air in the cartridge. Unlike on the spring side, the damper side stantion is open and therefore provides plenty of space for any excess oil.
Can you use belt wrench instead of that aluminum damper body clamp?
Hi! How much oil need to put inside demper? (in ml) approximately
Love this vid. Gave me the confidence to give it a go. Everything worked great except when I was done the h/l compression dials would turn. I followed a Fox vid and got into the dampeelr top cap. Seems my LS shaft is seized (won’t come out). Have no clue where I went wrong or what would cause that? Went down the rabbit hole on this. Air spring regrease (torch and all) went great. Any thought?
Hi Andy, thanks for the positive feedback!
I have an idea what caused your compression dials to seize - it happened to a few times in the past too.
When opening the screw which holds the compression dials, you may have inadvertently cranked open the screw against the pressure of the compression needle, rather than holding the dial and opening against the pressure of your fingers.
Sounds complicated, but in end effect you just overtightened (in fact over loosened 🧐) the compression needle.
With a bit of luck and care you can simply crank open the needle clockwise. Will need some Force and but not too much and don’t squeeze the head too much because you can easily crush it!
Hope this helps!
@@michaelherleth7848 Michael, go grateful for the response and so quickly. To clarify, I removed the retaining wire to remove the LSC coupler. Do I use the coupler with the dial (small black one) to remove the LSC needle (clockwise)? Or do I need to use a small socket on the LSC needle (clockwise)? Or, should I reinstall the LSE coupler and attempt to open the needle (clockwise)? So sorry to bug ya. Big thanks, Andy
Hi Andy,
I would reinstall the wire retaining clip and carefully turn the LSC coupler clockwise.
Cheers
@@mtbsuspensiontech I fixed it! I put a 4mm socket on the LSC coupler and turned it clockwise (slightest torque needed, more than my fingers could provide). Put it all back together. Smooth like hot butter. Not sure how I over turned the LSC (intially using palm on the topcap assembly during reassembly. Using 28mm socket much easier and safer). Fork is running smooth as warm butter now. Thanks for all the help and support.
Hi, what's your opinion about PTFE infused oil ? As I read here below, you don't specially recommend PTFE oil :-)
Super vidéo ! C'est la même chose pour une fox 36 j'imagine?
Yes, it’s almost exactly the same, only the air piston is a little different.
@@mtbsuspensiontech Ok, thanks !!
Great instructional video. What type of dust seal installation tool are you using? That doesn't look like a Fox model. Also, what FOX Lower Leg Removal Tool are you using? I don't see a version for the 38 Fork.
The tool I use is from Push Industries and I can highly recommend it! www.pushindustries.com/collections/suspension-oils-and-lubes/products/32mm-fork-seal-driver
@@mtbsuspensiontech Greatly appreciate the quick reply. Just found it. Any input on the lower leg damper tools? When I look at various sites none of them say they work on the 38mm fork. Kinda strange.
Sorry I missed the second part of your question - Both of the Lower Leg Removal Tools are from Fox: Spring side Part number 398-00-681 and Damper side Part number 398-00-682. Hope this helps!
A video for the fox 36 would be great to see unless it's exactly the same as the 38?
The lowers are the same, the grip cartridge is the same (if it’s a Grip and not a FIT/FIT4 fork), just the air spring is slightly different.
@@mtbsuspensiontech do you skip the cartridge work If it's a FIT/FIT4?
@@TheLeesto The FIT/FIT4 cartridge is completely different - I'll try and make a video on this in the near future.
Great work mate! Is this same to fox 32?
Is there a place to buy a bunch of lower leg crush washers?
These should be readily available online or ask your local shop to order you some.
Way are you putting fox float fluid in the top of the air spring and how much did you put in it?
A little oil, whether Float Fluid or 20WT Gold, helps keep the air piston moving smoothly. 3ml is plenty - remember that it will gradually wander past the seal and end up in the negative air chamber, so more is not better.
I have Fox 5wt oil that I've used on older Fox forks. It is not PTFE infused though. Can I still use it or do I need new PTFE infused oil instead? Thanks.
You can use any 5WT suspension oil!
@@mtbsuspensiontech Thanks for the quick reply.
Sir can i use dust wiper seals without flange as a replacement? Thanks
All newer Fox forks have wipers without flange 👍
@@mtbsuspensiontech thanks
You can make the 170mm travel to be 180mm travel on a fox 38 factory kasima ?
You sure can! Just need to replace your 170mm air shaft with 180mm
Correct!
what kind/brand of torque wrench do you use?
I have two from Parktool (3/4“ and 1/2“) and one from Hazet (1/4“)
how many time have i to cycle the dumper shaft ?
5-10 times is enough
@@michaelherleth7848 there's a way to see when it's time to stop, like no more bubles air like when i blead the brakes ?
Not really, but you can hear it/ feel it when the piston is free of air
My compression dials both high and low speed can’t move. Please help
Sorry I missed your comment - checkout some of my replies to other posts and I think you’ll find some useful tips!
hi for the damper do you need too fill it up to te top the 5wt oil?
thanks
You should fill it up to the small hole in the damper cartridge, you will see when you take it out of the fork
Thanks🙏🏻🙏🏻🙏🏻
No need for O-ring and seal replacement?
Not really, unless you have air loss problems or have several thousand miles behind you.
5 wt fox oil refil in damper how much cc
Fill up until it starts overflowing from the hole.
@@mtbsuspensiontech thanks so much .hope see more
What is the service interval on a fox 38?
Fox recommends every 100hrs / yearly
Posso inserirle prima le spugnette e poi i parapolvere......?
Sorry I don’t understand your language
The problem with inserting the foam rings first is that they will leave the casting oily and this means the seals won’t so firmly seated.
I may do the lower oil change every 2 years. Full service $200 at Fox factory, NO. 4 times service I can buy a new fork. XD
Your choice ... If you follow the instructions actually its not sooo hard to make a full service and you can ride your expensive fork for many many years!
The speed of this video makes it extremely difficult to follow along. Video should be .3x of what it is.
I recommend pausing as you go along if it’s too fast.
I purposely kept it short and concise so as not to bore those viewers with more experience/ knowledge of the process.
That is far from what it should do to service that fork. Close enough but still pretty far. Hopefully u just did not fillmed the important things.
The airshaft should be disaasembled and cleaned. Than greased.
The damper should dissaseble fully and cleaned. Changing the seals. Checking the shims for deflection damage.
The bleeding is so inncorect. It ahould be machine bleeded after the procedure u have performed.
No bad feelings. 🙏
I made a separate video for the airshaft - check it out.
As for completely disassembling the Grip cartridge: I would only do this if you have symptoms consistent with a poor performing damper. In the same way your car mechanic won't do a full engine teardown when you go for your service. Oil change - yes. More work than necessary - no.
There is nothing incorrect about this method of bleeding. Bleeding a Grip cartridge with a vacuum pump is in fact impossible - it is not a sealed unit capable of holding any signifanct pressure or vacuum (note the big hole on the side).
Thanks for your comments nonetheless, I like to be tested ;-)
present too fast
Thanks for the feedback 👍
@@mtbsuspensiontech I disagree- pacing was perfect. I've watched tutorials from other creators that would've taken 35 min to get the same info across. Appreciate a nice concise video with no filler!
Thanks Alex! Appreciate it - that’s exactly what I hope to achieve with these videos - concise instructions without the fluff!
Nope, just right. Thanks.
I want this guy to service my Orbea fox sus front and rear 🎉 can I book it in please, do you have a shop or is this directly from Fox ?
