Hello All,
Its been a bit since I posted last, but I read through this section quite often and I'm hoping someone here has some experience that could help me. Since i acquired my 580b its had an intermittent rotational tick in the rear end. It is most noticeable when moving at faster speeds and rarely is heard when moving slowly. When changing out the shuttle fluid and draining what looked like yellowish puke from the rear diff I went looking for a way to clean out the gunk from the rear end. After pulling off the rear access/pto cover i noticed something stuck in the sludge in the bottom of the case. I was hoping it was a wayward leaf or similar, but when a handheld magnet dragged out a single broken off gear tooth I knew I was in trouble.
At first I couldn't figure out where it came from, but after narrowing down by shape and size, then getting an inspection mirror at just the right angle while a friend slowly rotated the wheels, I saw that it had relatively cleanly sheared off of what seems to be referred to as one of the spur gears. Its one of the smaller straight cut gears that directly drive the 2 big final drive gears on either side of the case.
Question is, has anyone else had this happen or maybe can speculate as to what would cause this? after looking up the part it seems like that side is tied into the diff lock function possibly. Also, is this repairable without splitting the tractor? it seems like there is a removable side cover that hold this gears shaft in place....
Any info and relevant experience would be very helpful as a family friend suggested that the best option might be to simply fill it back up with gear oil and try not to strain it too much...
