WASHER (JLG JL91474049)

JL91474049: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the JLG catalog number JL91474049. The washer distributes the load of a threaded fastener across a wider surface area. A plain mechanical function of this type is to prevent galling between the fastener head and the mating surface. A concrete generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the softer material, reducing preload. During routine disassembly, a technician may find a washer that has deformed or cracked under repeated loading. Verify the serial number or application, then call (562) 693-7748.
