I was organizing the T18 parts yesterday and i noticed a chip in one tooth. It is only on one tooth, every one else is in great shape, seems like maybe it was dropped or something. Do you think it is Fine to run with?? Should i maybe file down the sharp edges, or will it just wear down while driving. It looks like it maybe it is the 1st gear. But please advise if it is good enough to run or should i repalce. like i said it is only on one tooth, everyone else is in great shape. Thanks!!!
