Frequently Asked Questions
Q: What equipment does the YL 518793650 seal kit fit?
A: The YL 518793650 is a seal kit for Yale electric lift truck steering orbitrol hydraulic assemblies. It supersedes Yale part number 518793602 and is equivalent to Aztec replacement kit YA-518793602.
Q: What is the pressure rating for the YL 518793650 seals?
A: The YL 518793650 seals are rated for 2500 PSI operating pressure, making them suitable for standard hydraulic steering systems in lift truck applications.
Q: What seal material and hardness does this kit contain?
A: The YL 518793650 uses nitrile (NBR) elastomer seals with a nominal hardness rating of 70 Shore A. Nitrile provides good resistance to wear and extrusion in hydraulic service.
Q: What hydraulic fluids are compatible with the YL 518793650?
A: The YL 518793650 seals are compatible with petroleum-based hydraulic fluids meeting ASTM D615 specifications. Do not use in synthetic fluid systems without verifying compatibility.
Q: How long do nitrile seals typically remain serviceable?
A: Seal lifespan depends on pressure cycles, fluid condition, and temperature exposure. Nitrile seals degrade over time; replace the YL 518793650 kit if you experience steering system leaks or pressure loss.
