B. HYDRAULIC SYSTEM OVERHEATING

1. POSSIBLE PROBLEM: Excess discharge pressure (relief valve set too high).

SOLUTION: Reset relief valve in accordance with maximum pressure required. Check

manufacturer’s recommendations.

2. POSSIBLE PROBLEM: Fluid viscosity too high or too low due to extreme ambient

temperatures.

SOLUTION: Replace fluid. (Check pump and motor manufacturer’s recommendations.)

3. POSSIBLE PROBLEM: Excessive internal leakage.

SOLUTION: Repair or replace any worn parts (loose packing, etc.)

4. POSSIBLE PROBLEM: Excessive friction.

SOLUTION: Check pump for part interference. Pump may be assembled too tightly.

5. POSSIBLE PROBLEM: Leaks in pump check valve or relief valve.

SOLUTION: Repair or replace.

6. POSSIBLE PROBLEM: Fluid level in reservoir too low for proper cooling.

SOLUTION: Maintain proper oil level.

7. POSSIBLE PROBLEM: Pump discharge being restricted.

SOLUTION: Check operation of throttle valve. Check relief valve. Do not allow larger pump

volumes to remain at high pressure for long periods of time. Check all self-sealing hose

connections for proper engagement.

8. POSSIBLE PROBLEM: Hydraulic system valves restricted.

SOLUTION: Clean valves and piping.

9. POSSIBLE PROBLEM: Heat exchanger not cooling hydraulic fluid.

SOLUTION: • Hydraulic circuit through heat exchanger is obstructed.

• Cooling coils in heat exchanger may be coated with a layer of dust.

• Airflow through heat exchanger may be obstructed.

• Cooling fan may be malfunctioning
