I just replaced both final drives on this machine. It solved my issue on one side (caused by a failed final drive) but I'm still having a problem with the other side.
Basically, when I engage the final drive on that side, the engine bogs down and the hydraulic pump whines like it's under strain. The final drive does turn, but not as fast as the other side. It's a brand new final drive, and the old final drive did the same thing, so I'm wondering what to look at to figure this out. I have a parts manual, owner's manual, and service manual - I'm just not sure where to start.
Any troubleshooting steps or help would be greatly appreciated. It's a 2004 Cat 304cr (NAD00987). Thanks!
