Hello all, new member here. Owned this B9200HST DP for a couple years now. Runs strong. It has a bush hog brand 1945 FEL. I use for the loader of course, and several 3-point attachments such as a tiller, box grader, wood chipper, 4 ft rotary cutter.
Last year I decided the hour meter may be unreliable as the associated mechanical tach was always flopping about like a winged bird. Found a NOS unit and installed... works great now. At that point I figured I could keep track of maintenance items better. So all the fluids were changed as a starting point. Most everything looked OK , except for the front right wheel oil. It drained out looking like a thin chocolate milkshake. No symptoms otherwise, and I typically run the machine in 4wd. Now to the point of my post.
This past winter, that front right wheel decided to spring a leak, as it sat on its trailer. After cleaning it up, the new oil (80-90 gear) looked to be seeping out from between the bevel gear housing "joint" . See pic:
I do not want to babysit this leak and just refill oil as needed. It must be fixed.
So after not finding any other exact posts on this tractor, but similar, I went ahead and started disassembly (as you can see)
At this point, I've removed the large outer drive gear from the hub, and dropped out the lower bevel gear out the bottom of the bevel case. Everything looks clean and crisp regarding the gears and bearing I've seen. Now for my questions; what should be my next step to separate the lower half of that bevel case from the upper half? I am betting that the oil seal located a bit further up that bevel shaft is the source of my leak. Also, how can I determine the reusability of the two shims that came out the bottom of the bevel case?
Thanks for any help you can provide!
