Bobcat 742 Lost all hydraulics

[jsantos]

This problem all started when i started to notice my right side wheels did not seem as responsive as my left. a couple weeks later, I was moving the machine when I heard some awful noise coming from the right side almost like chains or something like that. Within a few seconds, I lost all hydraulics and my machine started rolling down the hill. I took cover off chaincase and have attached pics.
I'm hoping someone can lead me in the right direction for why the bearing popped out and the loss of all hydraulics.
Thank you to all in advance!

Yeah, those cones shouldn't be seeing daylight like that, something has either come loose or snapped and spread apart.
In the manual thread there are both service and parts books for the 740 series, with the diagrams in them you should be able to figure out what happened, and what it will take to fix it.

Thank you for the response! Any idea what might’ve caused the sudden loss of hydraulics?

The bearning should not be seen like that, but it shouldn't have made the hydraulics stop working.
The only way it could stop the machine running is if all the oil was pumped into the chain case due to the shaft moving or breaking and letting motor oil pump in there.
