Have a EC160BLC and one of the travel motors locked up and sent brass and metal thru the hyd system. The other motor and swing motor were checked, resealed, and ok. The salvaged motor needed a new swash plate. Drained system, changed filters, and put back together. The high speed travel wasn’t working prior to the motor failure. Now the rebuilt travel motor is stuck in high speed travel. Unhooked the two speed line and it’s still stuck in high speed only. The new motor (aftermarket) works fine in low speed. It will work in high speed until switch to low and then it doesn’t go back to high. Main concern is the rebuilt motor stuck in high speed. Looking for suggestions if the problem is in the valve, motor, or where?
