The guy across the way from me at work rebuilds helicopter transmissions. In the process he must clean, inspect and re-pack bearings ranging from $200 to $3000 wholesale. (yes, they are overpriced just becasue they are aircraft)
His process is as follows:
1. Clean in a general degreaser tank.
2. Zip tie inner and outer race ( to assure they accidently don't spin while using compressed air)
3. Use compressed air to blow out.
4. Re degrease.
5. Blow out again.
6. Inspection (obviously a little more critical on an aircraft than an Airstream)
7. 2 dips and 2 air blows in MEK (Methyl Ethyl Keytone)
8. Remove zip tie.
9. Regrease IMMEDIATELY with appropriate grease or synthetic.
Using compressed air to blow off a bearing is EXTREMELY DANGEROUS.

The bearing can explode, potentially killing you such as a hand grenade. It has happened.

DO NOT SPIN A BEARING WITH AIR.

I'm sure it has. That is why you use a zip tie.

Question What's the physics?

Interesting, what is the physical process which produces the explosion? Atomization of flammable liquid followed by ignition from? Spark? Heat of friction?

Anything that spins, can explode. The question becomes what speed will that bearing take, considering it's been in service?

Not a good risk to take.

What a pro might do is far removed from what most do it your selfers might do.

Safety is the issue.

If your not trained "how to be safe" with most anything we may chose to do, then the safest thing to do, is "don't".

Let the pro's handle it.

scary!

wow, "anything that spins can explode." Makes me think how near death that guy from the Harlem Globetrotters was when he'd spin that basketball on one finger. Or those pie-plate spinners, on sticks, on old variety shows. I once saw a kid blow up from his yo-yo exploding!! Good, solid advice: ALWAYS have the "pros" do everything for you, you never know when your drill bit or saw blade could explode, like a grenade.

Wheel Bearings

Hi, I too was young and dumb. We used to blow brake dust in to the air and obviously breath it too. Not related, but after we found out how dangerous it was to blow brake dust, and stopped doing it, my neighbor died from asbestos lung cancer.
Now as to bearings, I used to do that too. Cool, spin that bearing held in your fingers to fifty thousand RPM. And yes, I grew up and realized, there must be an RPM limit before grenadeing. I stopped doing that too. We were told that the bearing could suddenly seize removeing all the skin from your finger. This is true and not a joke.
However, you can properly blow dry the bearings by blowing them from the side, therefore not spinning them.

From my personal experience; That's my story and I'm sticking to it!

Bob

You guys are killing me....!!!

You guys are killin... m...e.......!

OK, guess that the adrenaline junkies have moved on to bigger and better than air spinning bearings.... but still... funny stuff. That's funny! I don't care who you are.... That's funny! Credit, to Larry the Cable Guy!

No seriously! Then again, anything CAN kill/ maim you.

Guess if you don't know what you are doing, then get a pro. Gosh knows I have, and you should too... unless you know what you are doing or are reasonably proficiant and not brain damaged from kerosene/ carb cleaner/ brake cleaner/ gas fumes....

I learned at my uncles work bench (Caddy/Lincoln certified when that MEANT something!) and I would never deviate from what I learned. Bearings cleaning and reapacking was only one of MANY lessons!

Heck, we built a Manx Dune buggy one summer.... Worked on 2 Superbird's - one was purple!!!! ONE WOULD HAVE BEEN COOL! He had a '55 chevy parts runner with the 3 on the tree... an Opel cadet... several hotrod VW's .... Sorry, memory lane went by there!

Anyway, everyone be careful out there!

Axel

Stop, stop, I can't take it anymore. Ah, to even think about a summer spent with your own handbuilt Manx, that would be sooooooo cooooool. I think I was built a generation too late!

For those that don't have a parts cleaner, a couple of cans of brake cleaner is what most shop manuals suggest for cleaning several parts. I've used it in differentials as well. It dries very fast and I would simply make sure to dry the parts cleaned off just to ensure there isn't any brake cleaner left as it will break down grease when in a liquid form if brake cleaner were to come into contact with grease.

I digress again, sorry...

Eric et al -

Sorry, I repent. Even though I enjoyed the trip down memory lane SO very much...

Wrenches in hand are great therapy!

I'll endeavor to do better.... unless I am tempted....

Peace

for the record

for the record, i use compressed air to blow out grease and cleaner after cleaning after removed from spindle after wearing safety glasses!

how does a pro do this?
