A tight gear mesh will cause pre-mature clutch bearing wear...I run a OS speed, and i replase my clutch bearings every half gallon of racing.. that seems about normal life span for a losi clutch bearing without failure.

We used to have Losi's, I found out right away the Losi bearings suck. I used the cheap ones from A-main, on a weekend race I always put new ones in before the main. Then the next race I would practice and run the heats with the ones that were in it from the last race. (checking there condition once and a while) Then put new ones in for the main.
Lately on our Kyosho's I've been using the Tko radial thrust bearings and they are awesome! The cost over $3. but last 4 times longer or more.

Like mentioned a tight mesh will burn up bearings pretty fast . Also if you don`t have the engine squared up with the center diff that will also cause the bearings to go out prematurely . Not shimmed properly , to loose or to tight will also do that .

As usual chock it up to up to user error. I switched to a new larger CB and did not reset mesh. Thought the old mesh setting wold still work out fine. After 3 sets of bearings I decided to move the mount over and you guessed it ran all day no probs. Funny how such a small error can cause so many problems. Engine was getting hotter than usual too.
