Takeuchi tb135 turn motor extreme safety issue

Hey guys, i just purchased a 2002 tb135 with 3000 hrs. i got it home and when i started using it the following happened after 4 hours of use: the turn motor or swing which ever you prefer to call it will not swing to the right at all and when you swing left after you center the joystick it still swings very fast and makes a complete revolution before the brakes are applied. Even if you lift the safety bar it still swings. ( I almost took the side of a dump truck out). Has anybody had this issue?

Here is what I have done to troubleshoot so far. swapped the lines at the valve and rights swings left with no brake and left does nothing (rules out the joystick i imagine) returned lines to fac setting

swapped the two metal lines ont he motor right on the joystick swings left of the boom left on the joystick does nothing

I am stumped and in line for a certified takeuchi mechanic.

I would like to find a factory service manual for this machine that I can download . Anyone have any ideas?

All input is appreciated. Thanks
