Do you know what to listen for when inspecting your gearbox/reducers? Listen for abnormal noise. Noise inspection should focus on change in sound. Use an industrial stethoscope if necessary. If you don't have a stethoscope, you may also use a wooden stick to listen for noise.

Excessive noise may be due to:

• Misalignment
• Poor lubrication
• Worn/Failed Bearings
• Worn/damaged Gear teeth

Although gear-reducer is making noise, make sure that condition is not caused from other system problems, such as:

• Fluctuation in drive speed
• Coupling wear
