2003 Yanmar Vio27-2 Left driver slow

[x19m3]

Hello everyone,
I have a 2003 Yanmar vio27-2 that the left driver is slow and with no power only when goes back. When goes forward is fine. I did replace the hydraulic fluid and filter already but no luke.
Hope somebody can help.

How many hours. Sounds like a drive motor issue, gears or motor failure

Hours 4400. But if is the drive motor it should do the problem on both directions ( forward and back)? It works fine in forward direction.

I don't claim to be a mechanic , but just because it works fine doesn't mean it is ok. Could be having a problem in final drive that only binds in one direction.
I have run heavy equipment most of my life. Been on several excavators that tram fine in one direction but not in the other, always associated with drive motor or final drive. Good luck hopefully something as simple as dirt in drive motor workings.
