Frequently Asked Questions
Q: What is the compression rating on CR 79801?
A: CR 79801 is a compression spring designed for Crown lift truck assemblies. The exact compression rate (pounds-per-inch) must match your original equipment specification. Verify the rate in your equipment documentation before ordering.
Q: Which Crown electric lift truck models use this compression spring?
A: CR 79801 fits multiple Crown electric lift truck models. Confirm your specific model number, serial range, and year of manufacture match this part number in Crown service documentation.
Q: What are the material and dimension specifications for CR 79801?
A: This compression spring is manufactured to OEM standards for Crown equipment. Specifications include material grade, wire diameter, coil diameter, solid height, and free length. All dimensions must be verified against your original part.
Q: What symptoms indicate a compression spring needs replacement?
A: Replace CR 79801 if components it supports have excessive movement or droop, if hydraulic or mechanical pressure drops unexpectedly, or if the spring appears bent, damaged, or permanently compressed.
Q: How long does a compression spring last in service?
A: Compression springs typically last 3-7 years under normal Crown lift truck duty. Heavy cycling, corrosive environments, or overload conditions reduce lifespan. Inspect annually for corrosion or fatigue cracking.
Q: Can I use a different compression rate spring as a substitute?
A: No. Using a spring with an incorrect compression rate will cause improper operation, reduced lifting capacity, control circuit malfunction, or mechanical failure. Always use CR 79801 with the exact OEM specification.
