Frequently Asked Questions
Q: What is the 1315766 washer and what does it do?
A: The 1315766 is a flat washer used in electric lift truck electrical and mechanical assemblies. It distributes fastener load across a broader surface area, preventing nuts and bolts from damaging plastic housings, wiring terminals, or soft materials. Washers reduce vibration loosening of fasteners and prevent fasteners from sinking into component surfaces in warehouse equipment subjected to continuous mechanical shock.
Q: What material and size is the 1315766 washer?
A: The 1315766 is a metal flat washer with specifications that vary based on the fastener diameter and equipment application. Verify the bolt size, inner diameter, outer diameter, and material (steel or stainless steel) against your equipment documentation. Steel washers are used in standard electrical connections, while stainless steel washers are specified in corrosion-prone environments. Using the correct washer size and material ensures proper fastener performance.
Q: Which electric lift truck systems use the 1315766 washer?
A: The 1315766 washer is used throughout electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other OEMs. It appears in motor terminal connections, controller mounting, charger socket assemblies, and battery pack hardware. Cross-reference your truck model and electrical schematic to confirm the washer specification and bolt size. The washer size must match the fastener diameter to function properly.
Q: Does the 1315766 washer require maintenance?
A: The 1315766 washer requires no active maintenance beyond periodic visual inspection during routine equipment service. If the washer becomes corroded or damaged during fastener removal, replace it with a new one to restore proper load distribution. Steel washers in wet environments may develop surface corrosion; stainless steel washers resist corrosion better in these conditions. A properly installed washer under appropriate fastener tension has indefinite service life.
Q: What happens if the 1315766 washer is missing or damaged?
A: Missing or damaged washers cause fasteners to loosen over time due to vibration and shock loads inherent in lift truck operation. Without washers, bolts sink into plastic connectors or damage electrical terminals, causing poor electrical connection, corrosion, and intermittent circuit failures. Fasteners without washers also damage soft components like battery terminal lugs and wiring harness clips. Always replace damaged washers immediately to maintain reliable electrical connections and mechanical assembly integrity.
