Frequently Asked Questions
Q: What electric lift truck models use the 4942104 washer?
A: The 4942104 is a flat washer used in motor mounting, brake assembly, and electrical connection points on electric lift trucks from Crown, Raymond, and Toyota. Verify fastener size and equipment model before ordering to ensure correct bore diameter.
Q: What is the material and load rating of the 4942104 washer?
A: The 4942104 is a steel flat washer finished with zinc plating or stainless steel coating. It is rated for fasteners ranging from 1/2-inch to 3/4-inch diameter and distributes clamp load across a 0.5-inch to 0.75-inch contact surface to prevent surface damage.
Q: Why is a washer necessary in electric truck assemblies?
A: Washers prevent fastener heads and nuts from sinking into softer materials like aluminum or plastic mounting surfaces. They distribute pressure evenly, reduce vibration-induced fastener loosening, and protect electrical connections from corrosion by creating uniform contact.
Q: What corrosion or degradation should I expect from the 4942104?
A: Zinc-plated washers may show white oxidation or rust spots after 2 to 3 years of indoor warehouse use. Stainless versions resist corrosion longer but are more expensive. Replace washers showing visible rust, pitting, or loss of zinc coating to prevent corrosion spread to adjacent components.
Q: How long does a typical flat washer last on electric lift equipment?
A: Under normal warehouse conditions, the 4942104 lasts the operational life of the truck, typically 8 to 12 years. Washers should be replaced during any motor, brake, or electrical service to prevent corrosion and ensure proper fastener preload.
