I have a Daewoo dh 130-2 excavator . I’m looking for a final drive possibly used cause I don’t use machine much . Any body have any leads ?the one that’s on the machine now is toasts it needs to much work to it . My machine Serial number is 0883 and the final drive number is gm18vl-j-37/54-2. I don’t need the drive motor just final drive . Thanks
