Poke around for details

The problem is simple: it wasn’t installed properly, that is, it wasn’t restored to its original state; that’s probably the issue. Don’t ask anyone about this; it doesn’t matter what they say. As long as problems are not properly addressed, there will be hidden dangers. For gears, there are many factors to consider when installing them. For example, some require original marking installation requirements. They may seem the same, but the required values are like 0, 0 for 0 points. The adjustment of the bearing clearances at each point is all done on a very slight scale. The cover does not close properly; all of these factors are possible. Excessive gear mesh clearance leads to mechanical collisions and delayed rotation. The meshing is too poor, resulting in high rotational resistance and severe jamming. There is another non-technical aspect worth noting. That is—to not take on every task; do only those ones you are capable of handling, and for those you’re not qualified for, admit it and let someone who is competent take them on. If a risk is left unaddressed, it’s better not to do it at all, as the consequences will be worse. For reference.

The gear phase angle is adjusted by Dalian Rubber & Plastics. The installation was done by someone else. I just think that if it doesn’t seal properly again. What should we do at that time?
