What he doesn't mention in this video. There are 2 bearings in each side. So in the rear lower triangle there would be a total of 4 bearings. 2 press-in beside each other. If you look at the owners manual for your specific model you will see the bearings kit and the included number of each as well as a schematic of their location and number. I also found out that these bearings alot of the time are standard bearings that can be purchased at your local bearing shop. Knowing the bearing kit specifics will get you want you need. Good video over all but I immediately knew this information. Do your research. Keep shredding my guy
Thanks for pointing that out. It wasn’t supposed to be for this specific bike it was more just the act of pulling the shield off and re greasing it.
When I finally had courage to tear down my Spech Camber Comp MTB frame I was surprised to find the bearings were not completely shot. Even the one taking most load/wear at main pivot was still able to be cleaned, greased and re-assembled to torque specs without any headaches. I bought a long nozzle grease gun which is imperative. I was cycnial about not replacing until I saw prices for extractor tools. Even two tools (if available) runs over $100 for 12mm/15mm ID tools. The cheap one I bought failed so this was welcome news. I will have to do the whole thing eventually but bike runs great, no squeeks or weird knocks. Bearings were dirty, short of grease and definetely suffering. Behold cheap marine grease.
*Just an awesome **Latest.Bike** ....well constructed, sturdy, great looking…got me back out on the trails!! Could not be happier!!*
usually i dont watch smaller account videos and follow gmbn but the one time i do it's a good video. thanks for the help :)
Happy to help. Thanks for watching
Solid vid, surprising how many riders don't know to service their pivot bearings!
+Lucas Durham MTB this is the first time I've done it in 3 years and the bearings were still good. Extra grease never hurt anyone though
Interesting to note that you made a point of the arc through which the suspension loads the bearing but you did not take the bearing out and re zone it to present an unworn outer race to that arc position. If anyone decides to do this I would recommend using a permanent marker to mark the load zone on the outer race because when you take it out it will drop on the floor and you'll have no idea which area was the old load zone!
Interestingly enough since that video I have learned that, although I don’t think it’s very important, I agree
A big help I am planning to do the same on my bike thanks
Welcome
cool video.
My 17 year old Norco (with Specialized rear setup) is getting new bearings in today at the shop as they were worn out past maintenance. And yes, on one of the pivot, there are 2 BB side by side. Good news is that they are nothing fancy and my shop can get 10$/pc (from China) vs 35$ if from the USA.
Love love love maintenance videos. Just bought my '19 stumpy 29er. 🤘
Thanks. I love my evo too!
Anyone know each individual bearing for a 2019 specialized enduro 29 rear triangle? Companies dont ship to my country and each kit i see dont show what bearing goes where and what sizes each one is
Pull the old one and measure with a pair of calipers or get the bearing number off the shield and get a replacement bearing. I do it all the time
Doing this on my 03 enduro and the bottom seat stay bearings are tiny 688 side by side 😭, impossible to get out easily.
Completely prep the bearing first be fore removing seals. Tooth brush and cleaning fluid. Then remove the seals on both sides. I use brake cleaner to blow then out 100% of any debris. Let dry, clean the seals then repack and reseal. This way they last much longer.
This was q rookie job
Great vid.....you do need to do the other side however as these are two separate bearings separated by a spacer internally. Great instructions though.
Thank you. I did end up doing that other bearing as well off camera
Awesome man, thanks. Which torque wrench do you have? Do you recommend it? Looking to do this service on my stumpjumper as well. New sub btw!
I have a bikehand torque wrench. It's not the greatest but it works. Not for very high torque bolts like 30 nM but works for everything else
Cool video
Nice video,have you got any advice on 2007 stumpy fsr brain rear shock leaking hose ?please, I've only just found out what it's like to a decent trail bike instead of nice looking bike!
Honestly no advice for that issue. I have only had 16 and 19 stumpys. I would say its probably an issue with a fitting
would like to see more vids like this but you could definitely refine it a little. maybe go into more detail about taking off the swingarm / putting it back on and cut down on some of the wasted time. would make these kinds of vids a little more comprehensive, as opposed to tuning in with the job half done already. Good vid tho!
+Jordan Keeler thanks I appreciate the suggestion. And I totally agree with you.
+Jordan Keeler are there any jobs you'd like to see done specifically ? I'll be doing a lower leg service on my pike fork soon
suspension and dropper post service would be my suggestions, im personally pretty comfortable with everything else so maybe like basic derallieur tuning for any newer viewers
Do you have a video where you show how to disassemble the rear triangle of the bike (1 step before this video of yours). I have a Specialized Epic and I want to remove the annoying sound that comes from the pivots/linkage. Thank you
I don't. And I sold the bike yesterday. It's pretty easy. Just simple bolts
Not an expert, but just greasing and tightening the pivot points will usually get rid of the sounds that don't belong
Sweet thanks
My frame pivot bolts get loose from time to time should I buy a torque wrench tool?
Absolutely get a torque wrench
@@livefreeandshred9818 most mtb torque wrenches only have a max of 24nm, and my main pivot bolts need like 30nm, what should i do? Buy one that has lower nm, and another for high nm ?
Good video, I'm doing a rear service on a fsr tomorrow for a mate, do you know the recommended torque settings for bolts? You said 10nm, do you know what specialized recommend? It's not my bike, trying to be real careful
I'm not sure what the exact setting is. But if you call your local specialized dealer they could probably tell you. I use 8-10 nM on small pivots and about 15-18 for larger ones
LiveFreeandShred thanks for getting back to me, good channel dude, thanks for the info
Not a problem. Sorry I couldn't give you a definitive answer. Good luck on the service.
ThanksHow often should you service bearingsGreat videoCheers
+Daniel Pegan I haven't done it in 3 years bit taking apart and checking once or twice a season is a good idea
Nice
Your bike have there two bearings. You service only one.... Why?
+www only one there
LiveFreeandShred.. No it is two next to each other, 1:11 min
www hhhmmmm.....ill have to take it apart and check it again. I can't imagine I would miss that
Pretty sure the bearing your servicing is actually 2 bearings side by side. So pulling off the seal would actually be worth your time.
Yeah I noticed that after the fact. Thank you
LiveFreeandShred no worries man, it’s a weird design.
What do you think of that shock? Were you having performance issues with the stock fox shock?
The monarch plus is pretty good. If money wasnt an option I would go with the ohlins coil. If you do go with the monarch I would suggest ditching the autosag and get the debonair can. The stock CTD was horrible. And I'm having the same issues with the DPS on my 19 stumpjumper and ordering an ohlins tomorrow
@@livefreeandshred9818 is your primary issue having enough bottom out resistance?
Yes. That is the issue. I would have to use massive volume spacers and low sag % numbers to get bottom out resistance and then it would have no compliance on the small things
Super helpful video! Just subbed! I just started up a channel as well. Would love your feedback!
1) why did you service only one bearing out of two in the same location?
2) why didnt you take them out to clean properly?
1) honestly didnt realize there was two. Took it back apart to grease the other.
2) it wasnt dirty enough to need to be completely disassembled because I keep my bikes VERY clean
@@livefreeandshred9818 I just wonder what happens to dirt when you degrease it if it cannot 'escape' through the other side... it effectively still sits in the bearing. Man, those 'double' bearings are pain to service, difficult to take out as well
Blind hole bearing puller would do the trick nicely
How to remove the bearings is what I need to see
Blind bearing puller
Your voice sounds like codyko
....I dont know who that is haha
Please don't do this. You need to fully clean the bearings, then you lubricate them. And you should not be touching the lube to the bearing itself, that's a great way to contaminate your grease and contaminate every single thing thereafter. You can ruin bearings that were perfectly fine.
You do you brother. Im going to continue to do this.
Every one asking for a video of how to take it apart to this point if you can't figure that out you have no business doing this
