Sprockets
Thanks for the information guys, I think I will be able to get this done. I wonder why all dozer sprokets don't have the bolt on segments instead of replacing the whole sproket?
As I was told, the biggest reason, the sprockets are in segments, is so you can change them in the field, without breaking the track.
I personally, dont break, or loosen (unless its real tight) the track when replacing the segments. If you slack it off, all the way, you stand a chance of the track falling in your way. I move the machine, where you can get to a segment, remove the bolts and replace them. Its better to have a big impact (3/4 drive) and a good air source. I like to replace the nuts and bolts (most of the time, the nuts get messed up) they dont cost that much. Get them from the dealer, so you get the correct size and hardness. Just keep moving the machine and replace them as they come up. After you finish, check the tension on the track.
This is not a bad job, if you have the right tools. I have had to (in the field) to torch the nuts off and replace the new bolts, and tighten with a cheater bar.
This is my second, same reply to this post, so if another one pops up, it was my internet problem.
Good Luck
