Title: bearings
Post by: honda60071 on January 19, 2008, 09:13:43 PM
Hey, working on the bearings in my bike what is the easiest and less likely way of taking these out w/o damaging them or the dust cover. i.e. rear wheel front wheel? Thanks

"Did you try some 30 weight ball bearings. It's all ball bearings these days. "

I couldn't help it, I just watched 'Fletch.'

Wheel bearings will be damaged by removing them. There is no way to grab or push on the outer race to remove them. Removal is done by pushing or pulling on the inner race, this WILL damage the bearing. You could try heating the wheel until the bearing falls out - I have tried, never got the bearing to fall out, probably need to heat the entire wheel in an oven.

It is also bad for the wheel to remove them too often, wear and tear on the wheel. If the bearings feel fine, leave them alone. If the bearings do not feel very good, replace them (when in doubt, change them out).

Wheel bearing removal - http://www.motionpro.com/motorcycle/tools/bearing_remover_sets/
I have never used this tool, but others have said it works very well. I will probably buy it the next time I need to change bearings.

Well they are on a 04, seen alot street and track elements. I've seen rust on the inside of the hub spacer between the bearings . So I figured they need to be removed inspected and rust removed from all parts that have some sort of corrosion on them? Hinze friction causes drag and ceramics are going to be a nice touch to in the front and the rear. Thanks for the info.

The spacer is probably steel. If you remove the bearings, they will need to be replaced. How do they feel? I put my fingers in the bearings and spin the wheel and feel how smoothly they rotate.

I have over 90,000 miles on the wheel bearings on my street bike and they still feel fine.

 hi i took out my bearings (front and rear for powder coating)mysef and it was easy. after i removed the axle i took a long rod and knocked the bearing out using a crisscross  pattern from the far or rear side. the dust covers came out with the bearings. then took them to a industrial supply house and they cross-referenced the numbers and all 4 bearings came to 44 dollars. 28 each at the duc dealer

there are a few different bearing and seal drivers / removers or a press can be used
if they have some miles on them and are cheap enough to replace you might as well replace them.
but if they seem to be rolling well dont have any damage that you can see you can probably use them again
why were you taking them out?

The main reason was to clean off some rust that I noticed on the spacer in the hub. Not sure how bad but seeing some sort of rust on the inside of your hub can't be good. And everyone  is saying you have to replace them if you take them out, I decided to just replace them with ceramic after I'm done clean the wheels.

I have used the ones from World Wide Bearings. They were a better deal, he has most sizes in stock.

when you got them from world wide could he get the part by the bike type or did you have to give the sn off the bearing? Sorry Gary for not having more info. I did see where one thread on here was doing a group buy. Isn't there a bearing behind the front sprocket?

I had the bearing numbers, but he has them by bike. Give them a call.

 when installing bearings you first make sure there are no burrs in the wheel hub or in the frame for steering bearings. You can spend some $$ on  presses or hit home depot and get some treaded rod  and nuts and a assortment of fender washers and then pull the bearings(or races)  in from the far end.  this way they go in straight. if you got $ go to centralpaint.com and they will sell the press  for 159 and puller for 29 dollars   myself, i would go the home depot route and use the $ for more tires
