What happens here

To assess the condition of the pins and the swing motor, operate the excavator's boom to perform a quick, tight spin of the upper structure. Abruptly stop the swing movement. Listen carefully for any rattling, clunking, or excessive movement in the boom or swing assembly. Significant noise or slop indicates wear in the pins and potentially the swing motor components.

Goal: Check for excessive play in boom pins and responsiveness of the swing motor.

recommend you when an excavator gets old the pins get sloppy and that means there's a lot of give kind of like driving a boat when you're done turning one way the boat keeps going even though you're done steering that way an excavator is a lot of life except it'll rattle shake and roll and I'm going to show you a few different tests to use just to hear if a machine is loose or tight foreign so in a moment I'm going to put her in a tight fast Spin and then stop it so you can just hear how tight those pins are [Music] what you're listening for is any rattling any looseness but also at the same time that I'm doing this tight spin you can hear how well the swing you can kind of tell how good a condition the swing motor is in
