Hydraulic System: Troubleshooting
Problem
• The transmission bypass valve(s) is open or leaking.
• The wheel motor is worn or damaged.
• The transmission components (e.g., piston pump, relief
valve, and check valve) for the problem wheel motor are
worn or damaged.
Note: If 1 traction circuit component has internal wear or
damage, it is possible that the other traction components
are also damaged.
• The external traction control linkage is incorrectly adjusted,
disconnected, binding, or damaged.
• The steering cylinders are not synchronized preventing
front and rear wheel alignment (synchronize the steering
cylinders by turning in 1 direction and holding until all wheels
stop turning).
• The steering components are out of adjustment or damaged.
• The steering home sensor may be out of adjustment.
• The transmission bypass valve(s) is open.
• The brake is dragging or binding.
• The transmission-check valve is not seating or damaged.
