If I am not the only one who experiences the loud popping sound, like a tooth slipping when in a strain while backing up, i'll just live with it and get used to it. It really does not make sense that it could jump a tooth because it would have to jump several at one time, not just one. It would be nice to have someone on the ground watch it when it actually happens. Dickjr's explination sounds about right, the thing about loading up and bunching at the sprocket. I'll just adjust the track chains, ride it, and just smile when the old gal complains about the novice operator by popping loudly! Then I'll promise, one more time, not to put her in that kind of strain again. Thanks guys!
Nitelight,
I experience the same thing from time to time with my 941B. Its usually when I'm in a bind in a stump hole and put it in a hard turn. Not real sure what causes it. I just try to not put it in a situation where I think it'll do it. Does it less now than when I first started using it.
My current leak is oil around the filter housing but haven't been using the machine enough lately to address it yet.
