The Hydra 862-447 Stud is a precision-threaded mounting stud used in the pump drive assembly or motor mount of compatible Hydra sprayers. It provides a fixed anchor point for components such as the pump, motor, or drive housing, ensuring proper alignment and secure attachment.
Over time, studs can become damaged due to overtightening, corrosion, or mechanical stress. A stripped or broken stud can lead to component misalignment, vibration, or even catastrophic failure if the affected part loosens during operation. Replacing a compromised stud with this genuine OEM part restores the original fit and maintains safe, reliable operation.

When replacing a stud, it is common to service the fasteners and components that attach to it. These parts are often inspected or replaced at the same time.
Replace lock nuts or flat washers to ensure proper clamping force and prevent loosening.
Inspect the bracket for cracks or deformation if the stud was damaged by impact.
Verify alignment and check for wear on components that depend on the stud for positioning.
