Default Bearing prep

For my onroad cars I don't like to use the bearing grease that most bearings come packed with. I usually run Avid metal shielded bearings in my onroad stuff, and the Avid Revolution bearings in my offroad stuff.

My typical onroad bearing prep has consisted of pulling the shields from both sides of the bearing. Soaking them overnight in motor spray. Spinning them to make sure all the grease is knocked loose from any nooks and then spraying them to make sure everything is out. I then use bearing oil and then put the seals back on.

Does anyone do anything differently? I've been trying to think of something else to soak them in overnight. Motor spray is pretty spendy to sit and spray a bunch into a babyfood jar for one use. What bearing oil do you prefer?

Yup, blast out the grease with motor spray or brake cleaner then oil with a light oil.

Instead of buying $5 bearing oil in a little bottle get a bottle of Mobile 1 5w-20w Synthetic motor oil and one of these bottles:

It will cost about $12 total and you (and your buddies) will be set for life...lol!

Lacquer thiner is good for soaking. It's cheap.
Spray out with whatever afterward. I use CRC QD Electronic Cleaner.
It used to be cheaper than "motor" spray, but not so much anymore.

Just dont put rubber in the lacquer thiner (seals)

I used the motor spray in an ultra sonic cleaner too

I used a racing bicycle chain and bearing lube, smells like bananas and works better than anything i've ever used

I've been wondering if a small ultrasonic cleaner wasn't the way to go. I might have to try and find a small one. Thanks for all the ideas so far guys.

What amazes me is how many people (at least locally) were surprised I went through all the trouble to do this, until I showed them how much of a difference it can make.

Bearings are $1 each (or less) these days.....

1.)Install new bearings
2.)Put a few runs on the bearing and they loosen up
3.)When they get gritty toss them in the trash
4.)Repeat step 1

Yes, they are cheap. It's not about them feeling gritty though. It's about freeing up the drivetrain. In fact when they get dirty and gritty feeling I do toss them. For offroad I agree with what you posted, and thats exactly what I do. But for onroad it can make a big difference. Especially in stock classes such as VTA or even 17.5 blinky TC.

But have you ever compared lap times with and without that bearing prep?

Nope. Less drag is better. And if all it does is make me feel better about my setup then it was worth the little bit of time I spend on it once maybe twice a year. All kinds of things we do to our cars and don't compare lap times before and after.
