Hi Forum,
I'm can't seem to find any info on rear hub drive side bearing removal for a stock 2018 Kenevo. From what I have found I have a feeling I need a special tool to remove the (threaded?) pawls ring (not sure what the name of it is). I am pretty sure it doesn't hammer out the non-drive side. The axle does not have a lip on it either so I can't use the axle to pound it out. Has anyone removed this bearing? Can you give me some info?

Thanks!

I had my bearings replaced by my LBS. Getting them out was quite a job. They are supposed to tap out but mine were stuck fast. They had to heat the hub then really hammer them out. You don't need to/can't remove the ratchet ring.

TPP, thanks for the info. Do you know which way the drive side bearing punches out?
After examining it and rationalizing I figured there was no way the bearing could go out the non-drive side as it is pressed up against a lip in the hub. So does the bearing punch past the ratchet ring?

For anyone working on their 2018 Kenevo hub...
I can confirm that the drive side bearing punches out past the freehub ratchet ring. Holy moly it was in there tight though. Bearing is Enduro 6903. Drive and non-drive side.

I live in Seoul, Korea. I took my 2018 Specialized Kenevo wheel into Specialized Hannam Seoul Korea. They told me they didn't have the bearings in stock and it would be 1-2 weeks before they could replace the bearings. I said that was too long as I am a passionate and obsessive biker and that I would have to look for another option. I went home and ordered the bearings from a Korean website that arrived at my door less than 48 hours later.

Planning to fix hub myself as I could bear to wait 2 weeks I went to the local hardware store and put together a homemade bearing press. After a valiant effort I gave up trying to get the drive side bearing into the hub. I gave up and took the wheel back to Specialized Hannam Seoul just to have the drive side bearing pressed into the hub. 24 hours later (friday afternoon) I hadn't heard from them and I really wanted to ride that weekend so I went in to see what was going on. The wheel was still sitting there with the brand new bearing sitting in the drive side just as I delivered it. I asked how long it would take (even after I delivered the bearings to them ready to be pressed). The store manage told me 1-2 weeks as it was the busy season. It's prime riding time and I couldn't wait that long for ONE bearing to be pressed into the hub. I know how long it takes (with the right tool). I said that I would take the wheel and see if I could find another shop to press the bearing in for me. The store manager told me he would quickly talk to the mechanic and double check the time frame. I said that I had no problem waiting for that. So...I walked around the store ONCE. Before I was completely around the store the mechanic was at the cash register with my wheel. In less than five minutes it was done. They told me it would take two weeks. I knew damn well it didn't take that long to press a bearing! They charged me 300 USD an hour for the labor; less than five minutes. (I probably would have paid 1000 USD an hour just to have my wheel back for the weekend.)

Moral of the story...If you live in Seoul or plan to visit, I wouldn't recommend going to Specialized Hannam Seoul. As the Google reviews suggest, it is ridiculously over-priced and seems to be geared more toward people who don't really care how much things cost and prefer to be treated like kings and queens while they wait for elementary work, like flats, to be completed. If I were you I would look to buy your bike else where (like overseas) and also to spend the money to buy the tools you need to complete the work yourself. While they did get my bearing pressed within 28 hours I did have to hound them and then charged me 300 USD an hour for a 5 minute task.

Punched out with a socket extension bar.
Repalace with $10 Aud bearings. Bashed in with suitable size socket. Easy peasy

I’ve just changed my bearings in the rear wheel. First issue I had was that the largest bearing puller from the kit Iordered from Bearingprotools did not seem to fit properly and failed to remove the bearing. This was because I did not realise that the kit for my bike was just for the suspension linkages. Jim from bearingprotools has been very helpful and has since sent me the correct puller. In the meantime I managed to bash the bearings out with a drift once I had heated the hub with a hair dryer (good tip from this thread) and the press from bearingprotools worked well to press in the new bearings. However, second issue was that I ordered 6903 bearings but did not realise that 6903 bearings come in different sizes and mine had a 18mm internal diameter so when I put it all together the axle was slopping around in too large a hole! Back to square one, drift these bearings out, down to the LBS to get the correct bearings with 17mm internal diameter and press them in. Job done, eventually and some lessons learned!

No mate.....all 6903 bearings are 17/30/7.
The 18/30/7 bearing is called 18307......... but used to have the name 61903.

So what are these that I ordered? My LBS definitely said 6903 come in 2 different internal widths and the bearings that were sent are definitely 18mm and are marked 6903.

18307 which is as the order says is 18x30x7 rather than 17x30x7. You are better buying from a Bearing specialist who will also have a choice of bearing qualities and seal types. Bearing vary in terms of material used for the ball bearings and cage and the tolerance to which the ball bearings are manufactured ( e.g ABEC 3) as well as the type of seal used on each side . A decent version of this bearing can cost 3 to 4 as much as the cheapest. I change wheel bearings annually so go for a mid price range..........I use Enduro Bearings and for the rear hub I use 6903-2RS.
