PROBLEM | CAUSE | REMEDY |
Low fluid in oil reservoir/Leak. | Loose connection. Input and output seal leak. Pump leaks. |
Check steering system connection – Bleed the system. Replace steering – Bleed the system. Replace pump – Bleed the system. |
Foaming or milky steering fluid. | Loose connection. Fluid. |
Check steering system connection. Internal pump leakage. Replace steering pump – Bleed the system. |
PROBLEM | CAUSE | REMEDY |
Noisy pump. |
Low on fluid. Sucking air-oil foaming. Return flow too low. Growling noise. Rattling noise. |
Add fluid and check steering system connection-Bleed the system. Check steering system connection-Bleed the system. Replace steering pump-Bleed the system. Check restriction in steering hose. Check pump mounting bracket, contact between pressure hose and chassis or other parts. |
No Pressure. | Jam pressure relief valve. Pressure relief valve stuck. Pressure relief valve clogged. |
Remove, clean and ensure pressure relief valve smooth movement. Bleed the system. Realign pressure relief valve shim at end cap. Remove foreign particle(s) – Bleed the system. |
Pressure too low/too high. | V-Belt tension too loose. Pressure relief valve clogged. Wrong pressure setting. |
Adjust belt tension. Replace pump. Bleed the system. Remove foreign particle(s) – Bleed the system. |
Flow rate too high/too low. | V-Belt tension too loose. Worn cam ring. Clogged orifice. |
Adjust belt tension. Replace pump. Bleed the system. Remove foreign particle(s) – Bleed the system. |
