Red lead inspection of gear meshing in the speed increase gearbox gears of the catalytic booster

On-site photos of checking gear meshing using red lead for the gears in the speed increase gearbox of the catalytic booster, as well as checking the bearing bushings
What you mentioned is the use of red lead to check the gear meshing in the speed increase gearbox of a catalytic supercharger. Usually, this is a method to check the gear contact accuracy. Apply red lead to the gears and then rotate them; the red lead will leave marks at the points where the meshing is poor. By observing these traces, technicians can determine the running condition of the gears and make adjustments. At the same time, the support bushings will also be inspected to ensure their degree of wear and operating condition. However, I cannot provide on-site images at the moment. If you need to know the specific procedures and technical requirements, it is recommended to consult the relevant maintenance manuals or technical documents. .
The bearing shells are corroded and scratched; the lubricating oil is a bit dirty, and the filter isn’t working properly
Check the bearing shells; the oil is dirty, or the shells were not properly cleaned before being repositioned.
