Frequently Asked Questions
Q: What is the YL 506636500 pin weldment used for on Yale electric lift trucks?
A: The YL 506636500 is an OEM pin weldment assembly for Yale electric lift trucks. It serves as a structural fastener in the lift mechanism, steering linkage, or mast assembly, depending on the truck model.
Q: What are the dimensions and material specification of the YL 506636500?
A: The YL 506636500 is a carbon steel pin measuring 1 inch in diameter by 4.75 inches in length. It is fabricated from ASTM A108 carbon steel (SAE 1018 grade) with a welded construction per AWS D1.1 weld standard. Minimum Rockwell B hardness is B80.
Q: What bore diameter is required for installation of the YL 506636500?
A: The YL 506636500 requires a minimum bore clearance of 1.10 inches for installation. This allows for proper fitment without binding. Verify all mounting holes are clean and burr-free before installation.
Q: What causes failure of the YL 506636500 pin weldment?
A: The most common failure modes are fatigue cracking in the welded joint under repetitive loading, corrosion at the weld seam if the part is unfinished steel exposed to moisture, or bending if the truck is overloaded or misaligned. Inspect welds for cracks and the part for corrosion regularly.
Q: Is the YL 506636500 unfinished and does it require corrosion protection?
A: Yes, the YL 506636500 is unfinished carbon steel and is not coated. It is designed to operate in a protected location within the lift truck assembly. If the part is exposed to moisture or corrosive environments, surface rust may develop over time. Inspect periodically for corrosion and replace if pitting occurs.
