What is a necessary action regarding oil spray nozzles during any gear operation?

Keeping oil spray nozzles open during gear operation is essential for ensuring proper lubrication. Oil spray nozzles are designed to deliver lubricant to critical moving parts, reducing friction and wear as gears operate under load. If these nozzles are restricted or closed, it could lead to inadequate lubrication, resulting in overheating or damage to the gear assembly.

Open oil spray nozzles ensure that a continuous flow of lubricant is maintained, promoting efficient operation and extending the lifespan of mechanical components. It's necessary to ensure that these nozzles are not obstructed or improperly adjusted to achieve optimal lubrication.

While regularly inspecting the nozzles is important for maintenance, and capping or removing them could have detrimental effects, the primary function during operation is to keep them open for effective lubrication.
