Frequently Asked Questions
Q: What is the function of the YL 504863200 spring in an electric lift truck?
A: The YL 504863200 is a suspension spring that maintains ride height and provides dampening on electric lift trucks. It absorbs shocks from uneven floors and reduces stress on the frame and components. Worn springs result in a sagging ride height and increased wear on other suspension parts.
Q: Which lift truck models use the YL 504863200 spring?
A: The YL 504863200 is compatible with Toyota, Crown, Raymond, and Yale electric lift trucks in the mid-load capacity range. Spring force rating must match your equipment specification. Verify the spring constant or load rating against your current spring before ordering.
Q: How do you know if the YL 504863200 spring needs to be replaced?
A: Replace the spring if ride height drops noticeably, if the truck bounces excessively after hitting an obstacle, if the spring is visibly cracked or permanently deformed, or if the truck sits noticeably lower on one side compared to the other. Loss of spring tension cannot be recovered through adjustment.
Q: What causes springs like the YL 504863200 to fail?
A: Springs fatigue and fail from repeated loading cycles over time, typically after 3 to 5 years of heavy use. Corrosion accelerates failure in humid or outdoor environments. Overloading the truck or operating on extremely rough surfaces shortens spring life. Metal fatigue cannot be stopped, only managed through regular replacement.
Q: Should springs be replaced individually or as a set on a lift truck?
A: Springs should be replaced as a pair or set to maintain even ride height and stability. Replacing only one spring causes uneven ride height and unbalanced load distribution, which stresses other suspension components. Always order springs in matched sets for your vehicle.
Q: Can the YL 504863200 spring be bent back or repaired?
A: Springs cannot be effectively repaired or straightened. Heat treatment of a bent spring changes its material properties and causes permanent weakness. Replacement is the only safe and reliable solution. Attempting to repair a spring creates a safety risk and unpredictable ride characteristics.
