The 434-655 lock pin is a mechanical fastener used to secure components in a fixed position within compatible sprayer systems. It is specifically compatible with 0528925N_2000_4000; Hydr M nad Hydra Pro Super; and Hydra M and Hydra Pro 2000_4000 models. Lock pins are typically used in applications such as securing linkages, locking pivot points, holding adjustable components in place, or as a safety device to prevent accidental disassembly. The pin is inserted through aligned holes in two or more parts and is often held in place by a friction fit, a detent, a clip, or a cotter pin. It is manufactured from durable materials like steel to withstand shear forces and wear. Over time, lock pins can become worn, bent, corroded, or lost. A damaged or missing pin can allow components to move unintentionally, leading to misalignment, noise, or equipment malfunction. Symptoms of a faulty lock pin include loose or wobbly components, unusual movement of parts, or visible damage to the pin itself. Replacing a worn or missing lock pin with this genuine part restores secure locking and proper component alignment. This ensures that the sprayer operates reliably and that all parts remain in their intended positions. When installing, ensure the pin fits properly and that any retaining features are correctly engaged.
