Frequently Asked Questions
Q: What sealing materials are included in the CR 087488 hydraulic seal kit?
A: The CR 087488 contains polyurethane and nitrile rubber sealing elements designed for hydraulic brake manifold assemblies. Polyurethane provides superior wear resistance and durability under high pressure, while nitrile rubber offers excellent fluid compatibility. This combination is engineered specifically for Crown electric lift truck brake systems.
Q: What pressure rating does the CR 087488 support?
A: The CR 087488 is rated for hydraulic system pressures up to 3000 PSI. This high-pressure rating makes it suitable for demanding brake manifold applications in electric lift trucks where reliable braking performance is critical. Do not use this kit in systems exceeding 3000 PSI.
Q: Which hydraulic fluids are compatible with the CR 087488 seal kit?
A: The CR 087488 is compatible with ISO 32 and ISO 46 hydraulic oils commonly used in electric lift truck brake systems. These are standard industrial hydraulic fluids for material handling equipment. Do not substitute with non-approved fluids, as incompatible hydraulic oil can cause seal degradation and system failure.
Q: Is the CR 087488 an OEM replacement or aftermarket alternative?
A: The CR 087488 is engineered as a direct OEM replacement for Crown electric lift truck brake manifold assemblies. It is the genuine Crown part number and meets all OEM specifications for pressure rating, material compatibility, and dimensional requirements. Use this part for service restoration and warranty compliance.
Q: How do I know if the CR 087488 seal kit needs replacement?
A: Replace the CR 087488 kit if you observe hydraulic fluid leaks from the brake manifold, spongy brake pedal feel, reduced braking response, or visible seal deterioration. A slow leak may indicate seal failure. Do not delay replacement, as brake system leaks compromise equipment safety and can cause brake failure.
Q: Does the CR 087488 include all seals needed for complete brake manifold service?
A: The CR 087488 is a seal kit engineered specifically for brake manifold assemblies. Confirm that this kit includes all necessary sealing elements for your manifold model before ordering. If you need additional components such as springs, plugs, or check valves, contact us to verify the complete part list for your specific brake manifold assembly.
