FAQs
Q: What machines does 84296804 pressure relief valve fit?
A: It is for CASE N series and SN series backhoe loaders, including CASE 580N, 580N EP, 580SN, 580SN WT and CASE 590SN.
Q: What cross reference part number can substitute 84296804?
A: CNH part 47520559 is interchangeable and serves as the upgraded replacement option.
Q: What are the typical failure signs of this 230Bar relief valve?
A: 1. Weak operation and sluggish movement: bucket, boom or front bucket stalls when digging hard ground, the system cannot build up rated 230Bar pressure and excess pressure drains back to tank prematurely.
2. Abnormally high hydraulic oil temperature: continuous micro overflow creates friction heat, making hydraulic oil hot and thin rapidly.
Q: What causes the pressure relief valve to malfunction?
A: Common failure triggers include fatigue degradation of internal spring, worn sealing surfaces, and spool stuck by tiny metal debris circulating in hydraulic oil.
Q: What is the function of this 84296804 relief valve in backhoe loader?
A: It controls the overall working pressure of the multi-way distribution valve, acts as a safety valve to limit peak pressure and safeguard the whole hydraulic circuit during heavy-duty digging and loading work.
