Rear wheel bearings

Post by Fran » Wed Jul 17, 2019 4:11 pm

This is Fran from the Big Trip. I need some help we have a 16 GU and the rear wheel bearings are bad. A couple of questions could I remove the wheel bearings from the spare wheel and use them? What size are the bearings maybe I can get some here. I can have some shipped from Ural Miami but it would be a lot easier to get them here. Has any one changed these out and what is the procedure, do I need any special tools? Any and all advice is welcome and appreciated.

Pretty easily sourced bearing.

What makes you think your bearings are bad?

Thanks Albuquerque. Just realized the spare is for the rear thought it was for other 2. I will start hunting for the bearings tomorrow after I install the spare. To answer the bearing question, experience, I have owned a lot of worn out machinery, wheel wobble and cracking sound are typical clues. I really appreciate your help. Are they hard to change?

Wheel bearings are all the same in all the wheels.

Sorry never changed the sealed bearings in a Ural wheel.

They're not hard to change, unless they're really corroded into the hub, you should be able to change them out on the side of the road, with the tools provided in your tool kit, just make sure you put everything back together in the same order/orientation.
There's probably a video floating around somewhere if you start googling, or try myural, they're only slightly different than changing the old tapered greasable type.

Where is "Here"?

Are you sure the wobbling and cracking isn’t loose spokes? Pusher spokes can loosen quickly...just an alternative thought.

Look at the spoke nibbles for cracks

I agree.
I've had pusher spokes loosen many times, but I've only had bearings disintegrate once, they were the older greasable type, and I'm sure it was caused from my benign neglect :lol:

If it is the bearings and they are the sealed type, there is not much too it.

Here is the situation as of now. I swapped out the rear wheel for the spare. (In my last post on the big trip I called the spare a waste and just extra weight. How wrong was I.) That went fine the disc came off fairly easily and it all went back on the bike without problems. Are they serious about temporary use only or is it like the gas cans not being for gas? 80k max not an issue as that is our max normally.
I got one bearing out of the original wheel reasonably easily but could not budge the bolts on the splined flange. Luckily there is a KTM dealer nearby where they got the allen bolts off. Much beating with an impact driver finally paid off. The other bearing is now out and I decided to have KTM press the new bearings in. If they were not so convenient I would do it myself using the old bearing and the dreaded hammer but why risk more problems. I also got the bearings from them and a couple of spares. The owner has raced in the Dakar 4 times and when I let him drive Pferdi, muy dificil was his comment.
The cause is I think grease and dirt getting in and clogging the bearings I will have to add cleaning this in the future every 20,000k is my guess.
I have some parts coming from the US including the dust seal and as soon as I get that I will put the original wheel back on.
Thanks to every one for the advice and help you guys really have our back.
