Friend has a TB125, with 3500 hours, and machine will only swing. Swapped travel speed and lever lock solenoid, no change. Attached is hydraulic schematic. Original failure was occasional jerky operation, followed by complete hydraulic loss. Found no 12v to lever lock solenoid. Repaired wiring, and, now, swing only. Any ideas?
Good day If the blade works Ok indicates that P3 is good, strange how the pilot system is good for the slew and not for the rest of the system. According to my info the tracks are manual control are these working? Kind regards Uffex
Nope. House swing only. No blade, no travel, no boom swing, no bucket, no boom, no stick.
Good day Heymccall have you checked the machine for yourself, can you be sure the information is correct? Is here any history ? Kind regards Uffex
No history. Been too busy to drive put and check myself.
Ide pull the hydraulic filter and inspect first thing
Forgot to add. Filter was spotless. Had 250hr on it, from purchase.
So, just so I'm understanding this correctly, a complete hydraulic loss.....repaired some wiring, then swing only?
Yup.
It makes no sense. Im wondering if more is going on since you haven't seen it yourself
Yes. I'm befuddled. Won't visit it til next week or beyond.
