Have Truck Repair Questions? Ask an Expert
I am sorry no one could help you earlier.
Do you mean the machine will not turn with the travel levers?
The spools have no seals, they are fit to the bore of the valve.
You are more likely needing the seals in the rotary joint replaced. (Hydraulic swivel joint in the center of the machine.)
This is where the travel fluid is passed to the undercarriage to go to the drive motors.
Please let me know if I can help you with this or if you have already found an answer.
