Frequently Asked Questions
Q: What are the dimensions and specifications of the KO 11073-21 roll pin?
A: The KO 11073-21 is a 1/4 inch diameter roll pin with a nominal length of 1-1/4 inches. This larger-diameter pin is designed for high-stress applications in electric lift truck mast, steering, and drive assemblies. The increased diameter provides greater shear strength compared to smaller pins.
Q: Which electric lift truck models use the KO 11073-21 roll pin?
A: The KO 11073-21 is used in electric lift trucks from Toyota, Crown, Raymond, Jungheinrich, Linde, BT, and Clark across multiple model series. This pin is commonly found in mast guide rails, steering knuckles, and transmission linkage assemblies. Confirm your truck model and serial number to verify this is the correct part.
Q: What is the difference between the KO 11073-20 and KO 11073-21 roll pins?
A: The KO 11073-20 has a 3/16 inch diameter and 1 inch length, while the KO 11073-21 has a 1/4 inch diameter and 1-1/4 inch length. The larger KO 11073-21 provides greater shear strength and is used in applications experiencing higher stress loads. Using the wrong size compromises equipment safety and reliability.
Q: How do I identify if the KO 11073-21 is the correct pin for my electric truck?
A: Check your truck assembly manual or parts diagram for the specific pin size and location. Measure the bore diameter in the component where the pin fits; it should be 1/4 inch. Cross-reference your truck model and serial number against the parts list. If unsure, contact us with your truck model details for confirmation.
Q: What material composition and properties does the KO 11073-21 have?
A: The KO 11073-21 is manufactured from alloy steel with spring temper and a light protective oil coating. The coiled design creates internal spring force that holds the pin securely in place during operation. Material hardness and shear strength meet OEM requirements for mast and transmission assemblies in powered equipment.
