Default Bearing Problems.

Speaking of bearings, I have been having a lot of problems with my teflon sealed bearings. I run on carpet and it seems after every race I have to replace at least 4 bearings. Its usually the outside hub bearings. They get real gritty and some of them are hard to spin over. I tried soaking them in motor spray and alcohol overnight but that didn't work. I don't hit any walls so its not like a damged to races or balls inside.

Any help would be greatly appreciated.
Martin.

I take mine out of the car and spay into a Coke Bottle some Motor Cleaner. Put all the bearings in there and shake for about 5 min. usually the Motor Cleaner turns Black. Dump out and with hot water I rinse and then do the smae thing again. Second time around the Motor Cleaner should not get dirty. Then I take all the bearings and put a lot of Oil in them and spin them around until they are smooth. If they feel gritty that means there is Carpet Fuzz in them so I get that out or work it out. I leave them well oiled for a day or two and then I spray them out with Motor spray again and put a drop of Royal Oil on them and put them back in the car.

I probably do not have to do this anymore since we jsut got new carpet at the track that I race at... the old stuff had carpet fuzz everywhere. Now I will just check them to see if they are gritty and clean only the gritty ones.

I'm lazy and never clean my bearings... I guess that's why I am always buying new bearings.

Hey Mike... I think it also has to do with the fact that you stay in the groove and never really get out to the outer part of the track where you pick up the dust Bunnies . The Track looks good... Hope you come on Saturday.

Mike, really appreciate the how-to...

Never heard of Royal Oil...where can this be found?

The oil you use when you leave them well oiled for a day or two, is that also Royal Oil???

I had the same problem with the teflons on carpet. Using the shields on the wheels helped, but the carpet is very tough on the bearings.

I use an RPM Bearing Blaster, let em dry and use a single drop or Royal Oil.

Royal Oil is made by trinity... the Oil I use to soak them is Mobile 10W30 I think... just something to keep them from corroding from the water and it helps a little break stuff up that may be trapped in the bearing. I throughly was out the oil before I put 1 drop of royal oil

That should be alot more durable than the Delrin spool.
Use the IRS pin cushions which will help lessen the wear.

I recieved the delrin spool you sent...haven't had a chance to take the car out for a spin yet..hopefully this weekend. Without the screws..it's as light as a feather...

We made it a little thicker, so wear should be good.
It still came in at 8 grams.

Yeah, made out of delrin they are lite. Just have back up
ready to stick in. A buddy and I both broke one in
Shreveport this past weekend. The track was 2 by 4s,
if it would have made it there, it would make anywhere.

<<<<<this is genius!!! Eliminates the need for the special blades on the drive shafts. Like little plastic U peices, you could press them into the notches...
