Should I replace wheel bearings in wheels?

I recently purchased a front and rear wheel for the niner from ebay. I was planning on replacing the wheel bearing grease seals but not planning on replacing the wheel bearing due to seller saying wheels were low mileage. I was planning on getting the wheels powder coated and wasn't sure if I was asking for trouble not changing them. If it necessary to replace them, what is the best way? It looks like a pain in the ass! Any info would help.

Personally I would replace them. Get ahold of one of these tools. They make the task quite simple. Heat the wheel up a little with a hair dryer or heat gun, stick the main piece in the bearing, use the rod to expand and lock the main piece, then drive it out.



When you're ready to install the new bearing heat the wheel up the same way. It doesn't have to be smoking hot, just slightly warm. Put the new bearing in and use a socket the same diameter as the outer race to drive it home with a hammer.

I've done this quite a few times and always had good luck with it. If you use this method just take your time driving the new bearing in. Make sure you keep it straight. If it starts to cock at an angle then drive the high side to straighten it out.

That's my brief explanation. You can probably find longer writeups on the net.

I usually use the old bearing to drive the new in.

I've done that too. The only problem I had is when the old bearing gets stuck in the housing, hence a slightly smaller socket. It's all according to how deep the wheel bearing housing is.

HondaJim,

Is that a store bought tool? If so, is it called a bearing extractor? I work in the automotive field and they love to name certain parts and tools crazy things so when you go looking for them the people helping you think your smoking crack. If I can find the tool I will certainly change them out. Possibly a store like Cycle Gear might have them? Thanks!

they normally call them slide hammers, they have a weight that slides along the shaft and hammers the bearings out. I picked up a cheap one at HF and it works well... but it doesn't have the expanding ends like that one.

Yep, that'll do. Mine is a MotionPro and is about $20 more than that one now.

The set I have doesn't have a slide hammer. You hammer the end of the rod.

They are easy to check whenever you have the wheel off for tire replacement. You can rotate the inner race with your finger and feel for any roughness. The main thing is to make sure if you do feel something it's actually the bearing. The inner spacer will sometimes make you think you have a rough feeling bearing when it's actually the spacer.

Seems to me I got about 50 000Kms from the OEM rear bearings. Replaced with a non-OEM bearing and got 80 000kms before I replaced them and they weren't even too bad. Just peace of mind.

If you're getting the wheels powdercoated, you'll need to at least remove the wheel bearings. Whether or not you replace them is up to you.

Are there any specific brands of bearings anybody recommends? There has been a couple sets on ebay, but always would rather have a recommendation.

As a bearing engineer in a previous life I can say do your very best to not buy cheap bearings imported from China. There is real crap out there as aftermarket hardware. Life is too short to cheapen up on this.

Product from Japan, Germany, US or Europe from companies like SKF, Koyo, FAG, INA etc. are good manufacturers.

If it were me, if i could not pick up a part and look for the manufacturer, I would buy Honda OEM. Those would be from Japan.

my 2 cents,
Mark

All balls makes a good bearing. I have them in axle hub on my trx533r. Let me tell you if you want to torture a bearing put it in the hub of a good sport quad.

So far they have held up at least as good as the OEM's And I'm not the least bit a light guy and I sure am not afraid of heights.

Common sense. So rare it's a god damn super power.

Thanks for the heads up. Getting the bearing remover tomorrow and gonna send the wheels out. Can't wait to see how the wheels will look on the bike when they're done.

Just for our own curiosity...
When you knock out the old bearings look and see who the manufacturer was and where they were made. It should be embossed on the face of the outer race - very small letters.
Then look also at the new bearings to see where they are imported from. Bearing manufacturers are required to show this info on their parts.
Thanks!
Mark
