Tim,
I'm not trying to be lame or anything...but maybe you should read a little on the forums below you. About 5 posts below you I asked almost the exact same question--did you look at that?

No solvents

I don't believe in cleaning with solvents,i add lube, teflon type, blow them out with air, then one or two drops,done.I always suspect that if you wait for solvents to dry, or heat them to speed evaporation,the solvent will cause rapid or flash oxidation on the steel surfaces that are stripped of their rust inhibiting oil.And if you hurry up and put oil in before the bearings are dry the solvent wrecks the lubricating properties of the oil.Boy do i know some big words or what?:)

Cleaning Instruction

Hey, I thought I'd ask experts how I should clean bearings. The only time I did it: 1. Took the bearings out and took off the shields. 2. Put them in Ethyl Alcohol (70%) and shook gently. 3. Took bearings out, wrapped paper towel around it and shook gently. 4. Used Compressed air machine (one ot air up tires) and dried. 5. Wiped again. 6. Put two drops oil inside. 7. Put shields back on.
What should I do differently (should I soak them for XX amount of time?), and did is Ethyl Alcohol ok to use? Oh yeah, when i used the air machine, the bearing racers were broken and some parts flew out. They still roll, but is this a huge problem? Thanks for anyone who responds.

Bearing slop

On 1/1/2002 Herbn

(205.188.nnn.nnn)
Bearing to core tolerances are generally pretty damn good,any coning of the core happens because of the slop to the axle,creating leverage and momentum for stresses to damage the soft core,even an aluminum core is soft compared to the steel that the outer race of the bearing is made of.8mm axles minimize the benefits of spacers,especially on a carving board with relatively wide wheels,where the axles can never hit anything.standard axles should be 7.99mm,.3145 inches.

Cleaning bearings

Along with the moisture in compressed air, you risk driving air or cleaner into your skin. A good solvent is Methyl Ethyl Ketone (MEK). It is an excellent cleaner that flashes off quickly, just be sure to use gloves when you use it. If you use dish washing gloves throw them away when you're done, solvents degrade them quickly leaving them worthless.
I'm curious what everybody likes for lube. Any recommendations?

you did fine except using the compressed air. Never use compressed air on bearings for 2 reasons. You can drive any last piece of dirt (and there always is some left) into the bearing cage forever and also Compressed "AIR" when release contains moisture. Instead just tap the excess cleaner out of the bearing onto a paper towel or newspaper. 2 drops of oil then spin a few time to coat is plenty if you plan on maintaining them regularly.
USe a light grease if you plan on riding in rain or dirt..

I had an old set of generic abec 3's laying around and decided to use them as an experiment. An experiment to see if I knew how to clean bearings. First, I took off the shields on both sides (removed the c clips), and soaked everything in solvent for a few hours. Then, I took it all out, sprayed the bearings with compressed air to get out excess grease/dirt.
Next I rinsed everything in warm water and dryed/aired everything again. Then I applied a few drops of "mach 1 synthetic speed oil" by racetec to each one and re-assembled.
Just want to know: What did I do wrong? What did I do right? What should i have done? Is the speed oil alone enough when i stripped the bearings of all former lube? Let me know.
Thanks,
Luke

As usual, you get what you pay for, but it suprised me how much faster and smoother swiss bones are than china bones. china bones are nice bearings, im not putting em down, but i definitely like swiss bones better when it comes to strength. I would love to try the ceramics.. but i'm not big on spending 30 bucks on bearings even, it tore me apart to spend that much on swisses but im glad i did they're really nice =) hehe.

Bent shields

Most likely the shields are bent by the wrench, but there is one other thing that causes the shields to bend or actually cave in toward the bearings in a symetric depression.
If you use to much oil and it has any viscosity at all it will form a vacuum at high speeds (over 70mph on 76mm wheels) and suck the shields in until they touch the spinning balls in the bearing..
THat was a tough one to find.... one or 2 drops is all you need if you service your bearings regularly.

My friend bought me some Mach One speed oil yesterday...it's by "racetec." It is clear and looks pretty watery. It's also synthetic. Anyone know anything about this stuff? Is it safe/good to use on my china bones? Let me know anything you guys know about it. Thanks a lot.

These have a shallow socket and a very thick wall,allmost as big as the bearing,the socket will rest on the outer race and not dent shields.

The Old Elephant wrench is the only wrench to have! It was made to not go further than the nut when tightening. Of course you need to make sure u dont slam the wrong end of the wrench into your bearings. I have seen many riders beat the heck out of their bearings with all these new kook wrenches that probably help to perpetuate bearing sales.....

Fix that seal

(63.21.nnn.nnn)
Noah, remove the seal (see the Links section, there are several links to bearing co's that show how to remove it), you can straighten it with a little effort. When its loose, find a wrench socket that hits just the center of the seal, where the writing is. Hey, that one you bent them with is just the right size ! Place the seal upside down on a counter top, line the socket up carefully, and smash it flat again. Do this a couple times and the seal will be useable, if not as pretty as before.

This site rocks! I ask a question, go to dinner and come back to an accurate solution that I never considered! Thanks guys.....it actually kinda makes sense...I've used two different wrenches lately, one of which is new(different).
Merry Christmas, all. See ya in the new year!!

dented seals- not clubbing seals
|

On 12/22/2001 jg

(151.203.nnn.nnn)
Noah, the seal denting problem happens when you are tightening the nuts. The socket grabs the nut and when the nut tightens to teh axle it brings hte socket down also. The socket is what has dented your seals. To prevent this either- use a socket that lets teh nut always stick out some, or be super careful. I dent my seals at the worst possible time.... races when I am rushing to switch wheels.
If you use the deep nuts like on the old bennetts you probably won't dent a seal again.

Let's try this again
Noah,
I've seen this damage before. It is caused by the hex socket wrench. If the socket in the wrench is deeper than the thickness of the axle nut, the edge of the socket makes contact with the bearing shield and caves it in.

dunno why I'm directing that at bones swiss....judging by the damage, it would happen to any bearing. Axel washers, I think. ?

I really like Bones Swiss bearings. I have 5 well maintained sets and up intil now, they've been problem free. (BTW, I recently got a few sets of PT 7's sheilded and unsheilded...they're every bit as nice as BS IMHO)
Here's the thing: I just took apart my RIII which was mounted with RII 150's, some 83mm Flywheels, and Swiss bearings. My plan was to switch the trucks over to my Randal DH's. When I got the wheels off, I noticed that on two of the wheels, the outside bearing sheilds on the BS were "caving in"...looked like the forces in turning (maybe) were pushing the axle nut into the one outside sheild and crushing it. Weird thing is that the two damaged bearings are front right and back left...seemingly random.
There were speed rings in there, but do ya think adding another ring or two would prevent this in the future? Larger axle washers? I've been switching stuff around like a mad man for the last 6 months and haven't seen this happen before now. Is my guess as to what's causing the damage accurate? Anyone know if I can replace the bad sheilds on the BS with sheilds from old abec 3's?
Thanks
