Frequently Asked Questions
Q: What is a roll pin and where is it used on fork lift equipment?
A: A roll pin (also called a spring pin) is a hollow cylindrical fastener that secures components together by spring tension. On fork lift equipment, roll pins hold steering linkages, carriage brackets, and hydraulic cylinder connections in place. They are designed to shear under extreme overload to protect more expensive components.
Q: What are the dimensions and material of the 501900 roll pin?
A: The 501900 is a spring-steel roll pin sized for standard fork lift fastening applications. It features a hollow design with split construction that expands to grip hole walls. Verify bore hole diameter and length requirements on your equipment before ordering.
Q: What fork lift brands and models use this roll pin?
A: This roll pin is used across multiple OEM brands including Crown, Yale, Hyster, Toyota, and Clark equipment. Common applications include steering assemblies, mast connections, and load wheel brackets on electric and manual-drive systems. Confirm your specific model and component location to ensure correct fitment.
Q: How do I know if a roll pin needs replacement?
A: Replace a roll pin if it shows visible deformation, corrosion, or if components it secures have developed play or movement. Loose steering, rattling mast connections, or misaligned load wheels indicate possible roll pin failure. Pins that have been sheared during overload must be replaced immediately.
Q: Are there equivalent part numbers for the 501900?
A: The 501900 is a standard-specification roll pin. OEM cross-references exist across Crown, Toyota, and Hyster part systems. Since roll pins are commodity fasteners with defined dimensions, dimensions and material grade are more relevant than brand equivalents. Verify bore diameter and pin length for your application.
