Default clutch bearings without grease in them

I use avid clutch bearings. They are packed with grease pretty good. Even if i blow the crap out of them with an air compressor, they still make my clutch slip when they are new. I have about 20 of these bearings and would like to know if anyone has a secret for dealing with the grease. Once they get some time on them they are fine but then i have to worry about bearing failure. Would it be a good idea to blast them with brake cleaner and put a drop of oil in them? Or would brake cleaner shorten the life of the bearing and cause a dnf?

ALso does anyone know who makes them without grease?

I blast mine out with motor cleaner. Then leave them in Royal Purple over night (or a few nights). After soaking in the oil I mount them to a dremel and use a rang to catch anything that spits out. Once that's done I put them on my ride.

Go to walmart and get a few cans of non chlorinated brake cleaner. Its $2.50 a can. It won't hurt rubber or plastic. I go through 10 cans a month. I use it to clean out my shocks, my diffs, and spray out my bell and my flywheel

Marvel Mystery oil. They key is to not use too much of whatever you use so it doesn't contaminate the bell/shoes.

I've posted this somewhere else on rctech but have no idea where.. here's my routine:

2x fresh bearings: remove rubber seal and spray the inside bearing out with motor spray or nitro cleaner completely and run dry, replace seal. Outside bearing: untouched, doesnt matter if it slings some grease, it wont get inside your bell.

I'll run those through practice and quals then rotate the outter bearing inside the bell and put a new outside on before the main. Next race run as they are through practice and quals and rotate again before the main.

Doing this I havent had a clutch bearing failure in years and my clutch is the same everytime I hit the track.

I take a new set of bearings and simply put them in my clutchbell, and then install the clutchbell on my engine, install the engine, and then I start my buggy, and drive it for about 5-10 minutes in practice, and wow, it works perfectly for three race days or longer, never had any issues.

The oil flings out faster than the grease, so then you have a dry bearing hovering around 250 degrees with nothing in them. that's why most who remove the grease change them out every day or even before the main too. Not necessary, and wastefull...

RPM makes a handy little tool for this very purpose.

Use some nitro spray or electric motor spray and give them a couple blasts each. Then follow that with a couple drops of a good bearing oil. I use some Racers Edge oil. Nothing fancy, just bearing oil but it works well.

As for TKO's I'll stick with my dollar bearings.

BTW I use metal shielded bearings. They last longer than any rubber sealed bearing I've tried in the clutch.
