The 0278368 pusher spring is a mechanical spring used to provide force, tension, or return action within the pump or drive mechanism of compatible sprayer systems. It is specifically designed for use with SprayTech AirCoat and SprayTech ED655 Plus models. This spring works in conjunction with a pusher body or stem assembly, providing the necessary force to return the pusher to its starting position, maintain contact between components, or absorb shock. The spring is typically a compression spring that is compressed during one part of the operating cycle and then expands to push or return a component. It is manufactured from high-quality spring steel to precise specifications, ensuring the correct spring rate, load capacity, and fatigue life for its intended application. Over time, springs can weaken due to metal fatigue, corrosion, or stress. A weak or broken spring may cause a component to fail to return to its proper position, operate sluggishly, or not function at all. Symptoms of a faulty pusher spring include a pusher mechanism that does not return fully, loss of pressure, erratic operation, or unusual noises from the pump area. Replacing a worn or broken pusher spring with this genuine part restores the proper force and function to the affected mechanism. This ensures that the sprayer operates reliably and that all mechanical systems perform as designed. When replacing a spring, it is important to ensure it is correctly installed and that it is the correct spring for the application, as using an incorrect spring can lead to improper operation or damage.
