Frequently Asked Questions
Q: What material is the TO 00591-76721-81 pull rod pin made from?
A: The TO 00591-76721-81 is precision-fabricated from SAE 1045 through-hardened carbon steel with a minimum Rockwell C35 hardness rating and phosphate coating for corrosion resistance. The 30-degree chamfer on one end facilitates assembly into steering linkage components.
Q: What is the primary function of this steering pull rod pin?
A: This pin retains the pull rod assembly under repetitive shear loading in electric lift truck steering systems. It maintains a service factor of 1.0 for continuous-duty operation and ensures rigid coupling of directional control linkages.
Q: Which Toyota lift truck models use the TO 00591-76721-81?
A: This steering pin is used across multiple Toyota electric lift truck models. Verify compatibility with your specific equipment model and serial number range before ordering, as steering assembly configurations vary by model year and capacity class.
Q: What is the expected service life of this pin?
A: Under normal continuous-duty operation, the phosphate-coated SAE 1045 steel construction provides extended service life. Replacement is typically driven by wear in the mating steering linkage holes rather than degradation of the pin itself. Inspect for visible wear, scoring, or play during routine maintenance cycles.
