Wheel bearing help needed!

Hi all, I bought some used red oem wheels from a guy on here long ago and just got around to fitting some tires on them. When I went to balance them I realized the bearings are shot. The fronts are pretty tough to move but I can’t even budge the rears. I know the previous owner said they were his rain wheels so maybe thats why or they were overtorqued?
Anyway, I’m trying to locate replacement bearings for this 899/959 wheel and to avoid paying the overpriced ducati oem prices, I’m trying to locate them somewhere else like allballs/amazon/nts. I just can find rear wheel bearings, only front. Has anyone else replaced theirs?
Also any recommendations on tools such as bearing drivers, ect? Tips?

They have bearings that haven’t even been invented yet. Absolute # 1 place for whatever rolls.

Thanks but I have no idea what I’m doing on this site, seems like you need to be a bearing expert to understand the specific measurements and such. Anyone have a clue as to what the bearing/seal specs are for front and rear 899 wheels?

There should be information on the bearing itself on the seal that you can cross reference on their site. Additionally you can mic the OD, ID and thickness and cross reference from that.

Motion Pro make a bearing press kit that is good for bike sizes
Boca bearings is another bearing company
They also sell hybrid ceramic bearings

I used a motion pro kit to install my front wheel bearings

Thanks, was it relatively easy/have all the sizes you needed included with the kit? Did you have to heat the wheel like I'm seeing some people recommend?

Here are some pics for you. I dug these tools out and took some photos with the iPhone. And threw in another pic "Panigale by the full moon" LOL.

1. Yes I found it pretty easy but I always take my time to make sure what I am about to do is going to work.
2. The Motion Pro kit had the size I needed for the front wheel.
3. No I did not heat the wheel. I would not risk that as it may harm the paint on my wheels. I paid lots of money for magnesium and gold is a custom order. You can do the reverse and chuck the bearings in the freezer but I found pressing them is with some lubricant worked fine.

If you take your time you do not need the puller that is in the 3 rd photo. In that photo you will see a 5mm drift pin which I used to gently tap out the first bearing. The new wheels came with brand new bearings already fitted and I replaced them with the hybrid ceramic pair. Rolling friction is night and day.
I purchased the puller as it was not very expensive and was replacing bearings on another bike. I used the puller on the second bearing. If you are not doing this all the time you do not need to spend mega money on a known brand. IMHO. I have a very good set of HAZET tools which was special gift to self but I would not buy a HAZET bearing puller it would be 10 times what I paid for the KC Tools one. KC Tools is Taiwanese and good enough for the odd job here and there.

In the two photos of the MP stuff you can see how the driver and the two inserts fit together. All you have to do is line it up and gently tap in. If you had a wood lathe you could get some hardwood and make your own tool or machine one up out of alloy on a metal lathe. I do not have the skills or the lathes for that so just buy the right tool. Hope all goes well with the bearing fit.

cheers

on the rear wheel the sprocket carrier has a cir clip in there that must be removed prior to pressing

Thank you so much for the writeup! Very helpful. I was thinking to buy a cheap bearing driver and the pit posse bearing remover tool which isn’t too expensive and sounds like it gets the job done. I notice you said the promotion driver set fit the front but are you saying it didn’t for rear? Going to try and make sure whatever cheap kit i get has all the sizes.

Thanks for the heads up!

Hey guys, I don’t know why I’m having such a hard time with this, but doesn’t look like the bearing remover sets or driver sets have any sizes for the rear wheel which is about a 55mm diameter. Seems like front is pretty standard with 47mm. Thinking to just go with a socket that lines up and hammer in with an extension, think that would work?
Also, having difficulty locating exact matches for the bearings, front I can find but again the rear is an issue. If I order all the bearings and seals including the sprocket hub bearings from ducati omaha, I’m looking at over $200! For 6 bearings and seals!
Trying not to get ripped off and order direct but just having no luck with the rear. Here’s some pictures of the rear if it helps, the sprocket hub bearing have no indicators...

You couldn’t find that bearing at 123 bearing?
Also on the bearing tools I ended up using some 7075 bar stock and made drivers on the lathe. Unfortunately a lot of the bearing tool kits never seen to have what is needed

As for driving the bearings in sockets can work in a pinch, just be careful and use a deadblow hammer...don't want to fire a small fragment of socket through your body should it fail. Sometimes you can also use the old bearing to drive the new bearing in. You should notice a different tone once you have seated the bearing. Can also toss them in the freezer to ease the process.

Well I did find this, just a little unsure as this states 6005-DDU whereas the bearing in my wheel says 6005DU. Per NSK, DU means single contact seal and DDU is double. Thoughts?
Also, completely unsure on the seal since the only marking on this is AEQ0014A NOK, which doesn't lead to anything with the searches. Again, it's just the back bearing and seal that are giving me trouble finding..

The seal may be a bitch to source outside of Ducati or the wheel Mfg. Maybe shoot 123 a msg and ask them about the bearing. They have helped me find some pretty obscure stuff.

What size bearing puller is required fro the front wheel? Is it a 17 mm?

I think so, will check for you in a bit. Just a heads up, couldn’t find any sets that included the rear wheel size so I’m going to attempt to remove with a drift and hammer. Will let you know how it all goes. Also, I saw numerous people on the web and here mention you can use the old bearing to drive in the new one. But also heard the inner race shouldn’t be pressed on. Doesn’t that mean using the old bearing is risky since it touches the inner race? Sorry for all my stupid questions.

Thanks, Jack. I can use a drift/punch on the wheel bearings to remove them, but I’d rather not.
Regarding installation, I have a Motion Pro bearing driver that I use, not an expensive tool and it works well - so far I’ve only used it on the headset.

Actually looks like the front’s inner race is 25mm
