Frequently Asked Questions
Q: What is the 401340 locking nut?
A: Part 401340 is a locking nut used in forklift assemblies and load wheel systems. It secures axles, fasteners, and linkage components while resisting vibration-induced loosening during operation.
Q: Which forklift brands and models use the 401340?
A: The 401340 is compatible with standard forklifts from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Confirm your equipment model and serial range for exact compatibility before ordering.
Q: What size and thread specification is the 401340?
A: Contact us with your forklift model or reference image for exact thread size, pitch, and locking mechanism type. Incorrect size causes fastener binding or insufficient preload. Thread specifications vary significantly across manufacturers.
Q: How does the 401340 prevent fastener loosening?
A: The 401340 uses a locking feature such as a nylon insert, deformed thread, or serrated surface to resist vibration-induced rotation. This prevents critical fasteners from backing out during material handling operations, improving equipment safety and reliability.
Q: Can the 401340 be reused after removal?
A: Locking nuts with nylon inserts lose effectiveness after several removal and reinstallation cycles as the nylon degrades. Deformed-thread and serrated locking nuts may be reused if threads are undamaged. Replace if any thread stripping is visible or if the nut does not hold preload firmly.
