Frequently Asked Questions
Q: What is the CR 087490 cover end boot and where is it used?
A: The CR 087490 is a cover end boot designed for Crown electric lift truck assemblies. End boots are protective covers that shield internal components, rod seals, and bearing surfaces from contamination, moisture, and debris. This part protects critical mechanical interfaces on lift truck hydraulic cylinders or mast assemblies.
Q: What material is the CR 087490 cover end boot made from?
A: The CR 087490 is typically made from elastomer rubber or polyurethane compound that resists weathering, ozone, and hydraulic fluid contact. The material provides flexibility to accommodate rod movement while maintaining a protective seal against moisture and particulate contamination. The specific material composition depends on its application location on the lift truck.
Q: Which Crown lift truck models use the CR 087490 cover end boot?
A: The CR 087490 is designed for specific Crown electric lift truck models. End boot applications vary by mast type, cylinder size, and assembly design. Verify your equipment model and confirm the existing part number before ordering. End boots are not universal and must match the rod diameter and cylinder design.
Q: What happens if the CR 087490 cover end boot is damaged or missing?
A: A damaged or missing end boot allows dirt, water, and salt contamination to reach internal rod seals and bearing surfaces. This accelerates wear, causes rod corrosion, and shortens the life of hydraulic cylinders or mast assemblies. Replace damaged boots promptly to prevent costly seal and bearing failures downstream.
Q: How often should the CR 087490 cover end boot be inspected?
A: Inspect the CR 087490 boot during routine equipment maintenance or when servicing hydraulic systems. Check for cracks, tears, separation from the rod, or hardening of the elastomer material. In wet or outdoor environments, inspect more frequently. Replace boots that show visible wear or deterioration to maintain seal integrity.
Q: Is the CR 087490 available in different sizes for various Crown models?
A: End boots are application-specific and designed for particular rod diameters and cylinder types. The CR 087490 is engineered for a specific Crown lift truck configuration. Other Crown models may require different boot SKUs based on rod size, cylinder bore, and mast design. Verify your equipment specifications before ordering.
