What to Look For When Inspecting A Gearbox

Gearbox inspection typically involves several steps to ensure that the gearbox is functioning properly and identify any potential issues that may require repairs or maintenance. Here are some of the steps involved in our typical gearbox inspection:

  1. Visual Inspection: The gearbox is visually inspected for any signs of wear, damage, or other abnormalities. This includes checking for leaks, cracks, corrosion, and other issues that may affect the performance of the gearbox.
  2. Cleaning & Disassembly: The gearbox is cleaned and disassembled to allow for a more detailed inspection of each component. This involves removing the gearbox cover, gear train, bearings, and seals, and separating the individual gears and components.
  3. Measurement & Testing: Each component is measured to ensure that it meets the manufacturer’s specifications. This includes checking the gear teeth for wear, pitting, or other damage, as well as testing the bearings, shafts, and other components for proper alignment and function.
  4. Replacement & Repair: Any components that are found to be damaged or worn beyond the acceptable limits are replaced or repaired. This may involve using reverse engineering techniques to manufacture new components or making modifications to existing ones.
  5. Reassembly & Testing: Once all components have been inspected, repaired, and replaced as necessary, the gearbox is reassembled and tested to ensure that it is functioning properly. This includes testing the gear train, bearings, and seals for proper alignment, function, and lubrication.


By following these steps, gearbox inspections can identify potential issues before they become major problems and help ensure that the gearbox is functioning at its best.
