Frequently Asked Questions
Q: What Crown electric lift truck models require the CR 64020-7 plug pipe?
A: The CR 64020-7 is a plug pipe component for Crown electric pallet jacks and lift trucks. Exact model compatibility is determined by equipment serial number and hydraulic system generation. Consult your Crown parts manual or provide your serial number for verification.
Q: Can I use CR 64020-7, CR 64020-5, or CR 64020-007 interchangeably?
A: No. These three part numbers are not interchangeable. Each is designed for a specific model generation and hydraulic configuration. Using the wrong part number causes improper sealing, hydraulic leaks, and system failure. Always use the exact part number specified in your equipment documentation.
Q: What diameter thread does the CR 64020-7 use?
A: Thread specifications for the CR 64020-7 vary by model application. The part number indicates a specific thread size, pitch, and standard (NPT or BSPP). Verify exact specifications against Crown schematics or the original plug pipe to ensure correct fitment.
Q: How do I know if my CR 64020-7 plug pipe needs replacement?
A: Replace the CR 64020-7 if you observe hydraulic fluid leaking from the connection point, visible corrosion or pitting on the metal surface, or if the connection cannot be tightened without over-torquing. A failed plug pipe causes loss of hydraulic pressure and prevents equipment operation.
Q: Are there equivalent part numbers from other manufacturers for CR 64020-7?
A: The CR 64020-7 is a Crown OEM part. Equivalent aftermarket parts exist but may have dimensional or material differences. For Crown equipment, always use the Crown part number to ensure proper fit and system reliability. Aftermarket substitutes void equipment warranties.
Q: What causes corrosion inside a CR 64020-7 plug pipe?
A: Moisture-contaminated hydraulic fluid, exposure to humid storage conditions, and stagnant fluid left in the system promote internal corrosion and rust buildup. Regular fluid changes and keeping the system sealed prevent this. Contaminated fluid reduces component lifespan significantly.
