Haha! Just found this video. I purchased this same kit about a month ago and was just stumped trying to find a spacer for outter races. I feel better now, it's not just me....
Great video, demonstrating what you encounter in real time like this is so useful, I’m sure I’ll be referring back to this video many times in due course. Lol.
If the bearings are broken or used they will have movement in the raceway, so as you apply pressure to the inner ring it will push on the inner ring of the hood bearing, but the outer won’t, because it has a small amount of movement or give in it.
I have a similar kit like this that I use for linkage bearings and head tube bearings. I use the opposite side of the bearing spacers to extract smaller bearings and push on the outer race. There are no instructions with my kit, it was expensive, and not intuitive at all, but there have been a few times when I had to use a tool from another kit to match the bearing and place the piece in a vice. But using the reverse side of one of the included parts has worked, otherwise it would have been a huge waste of money.
for instalation if the bearing is retained on it inner diameter, as on a shaft, apply force to the inner race of the bearing. If the bearing is retained on the outer diameter, as inside a bore, force should only be applied to the outer race of the bearing. For removing the bearing you can do it either way if you don't reuse them.
You can order different size drifts from Wheels Manufacturing. It's too bad that there aren't more sizes in this kit. The really sad piece of this for me is that the bike industry doesn't have more standardized sizes, so one could feel safe with buying any kit and know that they have the sizing that they need regardless of what brand something might be. Thanks for sharing!
That’s a really good point. 🙂 unfortunately the WM drifts are a different ID for the threaded rod, so I’m not sure that would work well? Great comment all the same. 🙂👍🏻
The large sleeve seems suited for older (shorter) 9speed freehubs, this looks as if it's for older qr hubs. I'd imagine they have another kit for thru axle hubs (with a larger screw) and a sleeve suitable for the longer 11sp freehub. Seems incredible that they don't have parts to press in new bearings, unless this is a 'removal only' kit.
The handles come loose because the circular centre should have been counter bored so handle has a flat surface to seat on, but, for the price you can't expect $1500 tools design and finish. Didn't watch all of video as I'm not in the marked for any of that stuff, but, I have subscribed after watching a few video's , like you delivery and teaching style.
Thank you for an informative video. I can see a number of ways they might improve the kit but more parts equals more cost, and as you say its functional mode is not ideal. The hub with the rattelly preload tube seems a bit iffy for actual preload.
Thank you kindly! 🙏🏻 Yes and that’s a DT Swiss hub body right out the plastic bag from the factory. Never used. Very odd. But thankfully I only use it for demonstrations. 😁
What about this? 1. could you drill the square part out using a step drill and use a wide flat washer between socket and press. 2. A 3/4 inch socket (I think air guns might use this standard)) has a bigger square, 19mm.
If you only plan to work on your own bikes I'd just get the drifts you need rather than a full set, combine with some threaded rod and the fancy handle of your choice and Bob's your uncle. I know Hope sell a drift set for their hubs, I'm not sure about other brands? For suspension bearing removal/insertion I love RRPs drift kits, you just buy the kit for the bearing sizes you have on your bike. BTW, Hope hubs have an internal sleeve that makes bearing removal more complicated but they recommend, for their hubs at least, removing bearings with a pin punch. They even sell a special tool to hold the hub safely while you punch out the bearings.
@@reginaldscot165 Yes, we press the inner race, but so what if it is the race of a worn or damaged bearing, the new bearing is already pushed by the old one using the outer race and that's what @joystation1 meant i guess.
Hi. You press the first bearing without the axle. And the second one ,on the short side of the axle (left side). Never simultaneously, you risk a bearing going sideways and destroying the hub.
I agree with you and that’s the way I normally do it but on this occasion the manufacturers of the press always show it being used in the way I demonstrate. I wanted to give it a fair test so I followed their instructions. 🙂👍🏻
If you could find a flat washer, or make one, with the correct internal and external size to go over that tube, problem solved. The washer would also spread the load to the outer race.
Ordering a press from Alt Alt after watching your video, not as expensive as something like Wheels Manufacturing and it looks like it works. Their freehub bearing removal tool uses an offset hole instead of a puller, not sure about that, interesting though
@@reginaldscot165 I’ve got my eye on the Alt/Alt hub kit as well. The drifts are made from acetal to keep costs down, so maybe not the most durable for a bike shop, but good enough for the home mechanic. The bearing extraction tool is clever because it’s an offset eccentric cam, and pushes bearings out using a screw motion. Made in Canada.
Coincidentally my friend came over today with a worn hub bearing…. Would you recommend this toolset understanding the compromise or do you suggest any alternative? It looks like it does the job but not in the ideal way.
I believe there are plenty of better products available, including on Aliexpress. I believe ZTTO brand has a kit in a nice hard plastic box that seems much better. But, I’d recommend you find a review on RU-vid before spending any money. For me I can’t really recommend the kit in the video.
I bought the Ztto set recently and I'm very happy with it. There are a few rough spots with the machining, but in general the kit is really well made and drifts are sized correctly.
Acquired one of this kit and, I can say, it is half usable. Really hard to understand operation and the parts are for all the same inteligence: press or pull from inner race. Terrible! Partial solution is use old bearings to press new ones through outer race. And, macchine the useless parts that does not fit any standard hub/bearings to match our needs. Great video!
Yeah this kit has flaws, you really need to have over axle bearing adapter/ drift to push in bearing. I stumbled upon same problems buying this kit !!! In the end I was so frustrated not to find anything appropriate inside that kit that I wanted to buy lathe and make it myself 😠 I was looking for 6902 bearing over axle pusher. Nothing. What I ended up doing was to get old bearings to push in the new one. There is one catch though, you need lots of them over axle on hub side. Pressing on inner race is insane and a way to destroy your new expensive bearings. I'm still searching for solution. If someone finds anything appropriate please let me know.
That's a shame because with a bit more thought they have a beautiful piece of kit for very little money😢................never mind there's always the failsafe way to go.............. HAMMER it....😂 the you know who way 🎊🌟🥳🤩
@@reginaldscot165 well, if you were to ask anywhere else outside of China, or anyone else but the CCP, you'd most likely get the answer that island is independent with their own central government, their own democratic system (as opposed to totalitarian), transparent election, their own military etc.. Most anything that the CCP says contradict with the rest of the world. I'm not Taiwanese or live in Taiwan by the way.
Regarding the issue of avoiding pressing against the inner race would a simple washer overcome the problem (assuming there is one which fits and has a suitable sized centre hold for the rod)
Chinese are good at actually making stuff (producing, manufacturing), but not at designing. And here lies the problem. The kit is underdeveloped. For 80$ you are getting lots of tools, but making clip-on inserts to fix the issue of missing parts will set you back another $80 at machining shop, so this option is moot. At 160$ you'd find better kit for pressing the bearings in and out.
@@ssenssel I've only ever made one comment on a hambini video and that was telling him gatorskins were a terrible choice for british roads... But interesting you remember that comment somehow.
@@ssenssel It was a purely innocuous comment recommending a well known and affordable UK bearing press manufacturer over annodised aliexpress kits that have tolerance problems. I am a fanboy of noone.
