Wow, im glad I did some research before dropping $$ with enduro or WM. Someone mentioned you on a forum so I figured id take a look. Glad I did because those freehub extractors are genius! Im finally getting ready to buy a solid kit so I dont have to work like a caveman when replacing bearings anymore lol. Im getting ready to do all the suspension bearings on my levo and also my onyx hubs. Now I just have to figure out which bits of kit I need off your website!
That is a good "wish" indeed. I've had it myself. That shoulder, at the end of the bearing seat, which is keeping you from accessing the bearing outer ring is needed to transfer the axial load on the bearing to the frame (or hub). In some situations I can see designing something that would get around it, but the cost of the manufacturing of the bike/part plus the very intricate tool required for the removal would far outweigh the benefit. AND if you want to wish for something, wish that the bike manufacturers would put a flat and perpendicular surface around a bearing so that we can use a bearing press to remove the bearing. And for BSB configurations, make sure the bearing spacer can move off to the side. I for one would sleep better if I didn't have to tell customers that they're going to have to spend $100+ to buy a tool to remove that ONE bearing.
Excellent video, simple, to the point, no stupid comedian jokes, no soul searching personal therapy rants, no self-serving comments. Just the topic at hand and the topic only. Great job !!
Yeah, the number of pieces required to cover all the bases makes buying the whole thing as a home mechanic quite out of reach. I'm now working on individual piece sales so that you can sit down, figure out what you need and then order only those pieces. This will be more cost effective! Also working on a video to help you figure out what you need.
stunning new design(s). I am a local customer who bought the the first ALT/ALT kit during your initial release. Makes me want to get some more goodies for some bearing ASMR, lol just need a product page link in your video notes
I'm not "knowledge people" he mentions, but I've used this guy's bearing press kit enough to learn that it really is a GREAT kit! I absolutely LOVE the alt drift! If you're looking for a bearing press kit, I'd REALLY consider this one if I were you. Worse case, get some ride buddies to pitch in some bucks to buy it. I don't know the guy, I have no affiliation with him. Besides him being Canadian and sending us his cold weather 6 months a year here in MI, he seems like a nice guy 😁 One thing I do know is that I really like his tools. 👍
You truly have made the most comprehensive bearing press/ extraction system on the market. I do not think I can live much longer without adding your complete setup to my service shop. Well done!
@@altaltbike You are very welcome; thank you for making a thoughtful tool set! I have almost pulled the trigger on pre-ordering that Alt Extractor kit so many times... I am sure you will see an order from me soon. It is the best solution to BSB scenarios I have seen in the 21 years I have been wrenching in shops. I can't wait to add them to my box! They look like a joy to use
6805 is 25mm inner diameter, so yes. There is a size for that. PS. check this page for more information about the ALT Extractors. www.altalt.ca/alt-extractor
May I ask what kind of foam the drift kit is mounted on? I'd like to build up something similar to what you have here for the remainder of the kit for some nicer storage.
Hi, Steve. It seems a nice tool! 🙂. Do you think that this is a better solution that your ALT Drift kit? I purchased it some time ago and I've only used it once (successfully, by the way). But after watching this video, it seems to me that this last proposal is quite more convenient. Thank you!
You are correct. The ALT Extractor is a superior tool, but the intent for the ALT Drift was never to make the ultimate tool. The ALT Drift is a simple, effective, controlled and inexpensive way to remove the first bearing in a BSB configuration as long as the bearing spacer can move off to the side more than 1mm. The ALT Extractor doesn't need the bearing spacer to move off to the side and it is meant for frequent use. It is also available in 10 and 12mm bearing ID. The down side is that it is also going to be over twice the price of the ALT Drift. There is no need to replace your ALT Drift until you run into an issue where your bearing spacer doesn't move off to the side or if you need a 10 or 12mm bearing ID size. At that time (soon) you can get a single size ALT Extractor to fill in the gaps ...unless you geek out on tools in which case you will need all the sizes to be ready for anything.
@@altaltbike Thanks for your clarification, Steve. Beyond the 1 mm gap condition and the 10/12 mm ID options, it is undeniable that the ALT Extractor tool offers a much cleaner and more elegant solution.🙂
Elegant indeed, but I still stand by the ALT Drift design. It works like a punch and hammer that is infinitely repositioned around the bearing as it is removed. The punch and hammer has been a widely acceptable method of removal ...although not great for people who don't do it often.
Hey, Steve. Thanks for cool video. One thing I don't you didn't mention. What if inner surface of my bearings will be bigger than your tool's outer edge significantly? Will there be different sizes of this tool? Does it come in one kit? Or you think one size is enough for all bearing sizes? Thanks for your continuous improvement approach! Hope the price for new tool will be as fair as for everything else in your kit.❤
I'm not exactly sure what your question is, but check out the webpage in this link. If you have questions after that please email me through my website. I'll sort you out. www.altalt.ca/alt-ext
Yes. Right now it's in production. This extractor is to be used with the leveraging pieces in my bearing press system. I will also have a stand alone kit that includes the extractor as well as the leveraging pieces from my system.
Hi Steve! There may be some misconception about AC bearings. I can't prove that it is always the case but i remember seeing symmetrical bearings in hubs which just have custom seals. like a non-contact type on the inside and a double lip contact on the outside. also there is no point in AC bearings in BSB arrangement... not in a bicycle anyway. As for real AC bearings, there is one funny nuance. because they have much less contact area in the opposite direction, they are easy to damage when punching out. Good luck getting that seized outer race out! I see how your Alt drifts may help with it greatly. I have not seen a better all in one press yet. I think there is room to make a higher-tier model with trapezoidal thread, stainless steel parts and maybe an adjustable bearing catcher with 3 or 4 points of contact where each of them can be moved individually to match the diameter and slope of suspension linkage part. If you catch my DRIFT (which i will be using to extract bearing for a forseeable future).
Whoa! Good stuff. I can understand a symmetrical bearings can have different seals in the case where you need a strong seal on one side, because that is where the water and debris comes from, while the other side is protected from these elements. Like in a BSB configuration. This reduces the drag of having two tight seals on the bearing when only one is necessary. As for AC (angular contact) bearings in BSB configurations (like in hubs) you'll notice that the bearing inner ring is sandwiched on both sides by "stuff" which hold it in place, while the outer ring is only supported on one side (the inside usually), which means that "primarily" the force travels through the bearing in one direction. An AC bearing is stronger than a symmetrical bearing in this direction. This is the explanation that helps me sleep at night and is just my understanding of the use for an angular contact bearing. Adjustable bearing catcher!?!? That's witchcraft. You're crazy. It's not possible. No way. No how. ...hmmmm???
@@altaltbike Yes, that is the case about different seals. Some hubs are advertised to have this for lower friction. I have an allergy to marketing bullcrap like that. From my understanding AC is good for adjustable systems. Like hubs with preload collars or Intense, Cannondale, Santa cruz pivots with adjustable collets. Btw i recall seeing Cannondale Habit 2019 main pivot with symmetrical bearings and NO spacer (with a preload collet type axle). Makes me think that AC is not that important even in a headset (cannondale lefty/fatty seem to use usual bearings). But im a fan of AC headsets because of self centering. Like, you can’t perfectly preload two AC bearings in BSB configuration to achieve maximum stiffness and durability like in a AC headset. Two symmetrical bearings in BSB are good enough to me because they don’t need preload adjustment and spacer help to distribute axial loads between two bearings because inner rings move together thanks to a spacer. I want to machine a spacer for my Habit main pivot to achive this mode of load distribution. As for that catcher idea…. It’s not that crazy really. Three or four threaded studs with non-slip feet movable radially to adjust to different diameters. I already want to try and make one lol. But my drift kit will not ever forgive me for this.
It's amazing how fanatical we get about 0.001" of play when some designs just ignore it all together, and do all right. ...and your idea is intriguing. It would definitely have a use in the bike industry.
@@altaltbike once again, the work you’ve done is very impressive. Most other presses seem to be low key copying each other but your product was thought out independently and here is the result! Are you an engineer by chance? I’d love to hear more about stuff you’ve done back in the day.
HELLO BROTHER EXCELLENT VIDEO I AM A BEGINNER IN MTB COULD YOU SHARE THE ADDRESS WHERE YOU BOUGHT THE TOOLS -HOLA HERMANO ECELENTE VIDEO SOY UN PRINCIPIANTE EN LA MTB PODRIAS CONPARTIR LA DIRECION DONDE COMPRASTE LAS HERAMIENTAS
You shown us a solution to removing a bearing from a non flat surface using a slide hammer. What is the solution for replacing a bearing in the same situation?
Sorry I missed your question. Removal, blind bearing puller (now but I'm developing something). Install should be normal bearing press unless complicated by extended inner bearing ring. There are more details that I can help you with if you email me the bike model and pivot.
Są bębenki jak w trenażerze Neo Tack, jedno i drugie na zewnątrz dodatkowo za wewnętrznym jest rozparty pierścień segera, najlepiej jak ktoś zabije łożysko i zostanie wewnątrz bieżnia zewnętrzna 😂.
YES! I cannot believe this has not existed until now! For me this may come too late as I gathered many different tools and adapters and so on already, but for someone who has not yet invested many hours to find the right individual tools, this is simply GENIUS and will save many hours of internet search and frustration!!! Thank you!
can you crack a carbon fiber frame pressing a bearing out crooked? i was pushing my lower shock bearing out of carbon slash and heard a loud crack when tightening down the press but idk if it was the bearing breaking loose or frame cracking. it was seized in bad and could not be pulled out with slide hammer so i pressed it out.
Awesome vid Steve. i kept waiting for you to mention me by name but alas I remain anonymous. I'm waiting to hear from Cannondale about the HG freehub. I guess whilst I'm waiting I should order the extraction tool. Any that you would recommend? Thanks
What do you know about the HG brand FH-513 freehub? It looks like both bearings have to be removed through the outboard side. The inner sleeve does not offset at all much less 1mm for the drift tool to be used.
I just ffed up the freehub. Bizarre construction. This was the newer version, that has a seegerring on the inner bearing. After destroying the bearings, I see the inner one is larger than the bore. No idea how to get it out
@@altaltbikeIt's the new version. I'm still puzzled how they got the inner side bearing in. It is larger than the bore. So I thought maybe there's a sleeve on the outside? It's bizarre and totally unnecessary. I'll update when I figured it out.
@@altaltbikeMaybe you already know the construction. I got the bearing out. Measured the fit and it is 0,05mm under nominal. That will have been the reason the bearings were toast within a year. I will email Race Face, can copy you in if wanted.
Im sososososo happy that you have taken the initiative to create your products AND create videos on how to use them!!! I working in a bike shop years ago before university and always stuggled and was intimidated with bearing, i hated the hammering my bike to pieces to replace a 10$ bearing. Ive got your kit in the mail and am super excited to controllably replace all my bikes bearings! (Suspension and hubs). Huge kudos man.
Hi Steve! Thank you for addressing the (should be) very delicate subject of bearing swap. Your tool is the most comprehensive I have found yet, so kudos for that. However, I wanted to ask you... I'm an avid user if Bitex hubs, and my front QR hubs have a 5mm ID axle which wouldn't make the press work, since the stud wouldn't enter into the axle. What would you recommend for that scenario? Is it possible to get or use your kit with that size of stud?
My tools are designed for modern mountain bikes, but contact me through my website and I'll be happy to look into this for you. AND THANKS for bringing new customer needs to my attention! Much appreciated.
This is somehow satisfying video. Something like Dream build but for mechanics!😂 insted of fancy bike parts it's fancy tool. Please dt swiss 370 and 350 and i9
As a mechanic that only works on bike these days as part time I only do bearings a couple times a year, this is a great kit, when I had a metal lathe I wanted to build a similar kit however didn’t have the time or access to enough variety of bikes/hubs to design a complete kit. Can’t wait until you offer delivery to Australia
