problem with tc3 bearings
I am having a problem with the bearings in my ft tc3. After I ran the car a few times the bearings in the block carriers got really grainy and eventually locked up completely so I replaced them. And after I raced the car a few times they did the same thing. I sprayed them out and re-oiled them after every couple runs but they still went bad. I race in the stock class on carpet at my local track and we use foams. Thanks

Nothing much you can do about damaged bearings. Every time you hit a board you will place a tremendous amound of load on those bearings which is why they fail. You can try removing the shields and spray it out. Its also best not to spray out your bearings if you want them to last. The bearings will last longer with the original grease in them.

You are not alone micro speed - had same problem with the original equipment bearings too - only the 3/16 by 3/8 in my car, the large bearings have been ok. Tried to clean them but no success. Replaced with a cheap duratrax set and and lap times went way down and they are still free and smooth after several months of carpet racing.

the bearings in my ftTC3 lasted a couple seasons, i recently replaced them with middle-of-the-road Acer bearings, i have been very pleased with them so far

The statement about hitting boards is correct. This seems to be the foremost reason for premature bearing failure. Everytime you hit something, the balls in the bearing make a small dent in the bearing surfaces. Of course, make sure you have good oil them as this will also cause problems. Additionally, check when you clean them out to see if there are any carpet fibers stuck in the the ball race. Nylon is a notoriously hard and abrasive polymer.
To give you an idea how abrasive it is, we use ultrasonic slitters(basically a very powerful tweeter) with a surface hardness of 63c rockwell hardness to cut through nylon fabric. we have to rotate the horn to a new section every 4 hours or so because the nylon cuts a groove.
If you are picking up a lot of fuzz on your cvd's, chances are it is getting in the bearing. If it is, clean more frequently.

Doug,
The bearings are teflon seals. What I do is take off the inner seal for all the bearings, spray them out good with motor spray and/or put them in the Integy sonic cleaner thing I have for one hour. Then I put some light bearing oil in them (1 to 2 drops of ACER SIN lube, my preference). Make sure you put the exposed side on the inside of the hubs/diff cases.

correct me if im wrong, but did you say put the exposed side on the inside of the hubs? so this means that you do not put both seals on your bearings? im fairly new at cleaning bearings and im trying to discover what's the best metho of cleaning them.
another query, can i use the rinity bearing oil on my bearings? tanx a lot.
