G29 Transmission shaft movement

[Heaths]

Hi, I'm working on a Yamaha G29 with an electric motor. A friend of mine asked me to replace some bearings and bushings in the electric motor. After removing the motor I decided to spin the transmission shaft just because you never know. When I changed directions it almost felt like I was picking up a set of gears, or pulling the slack out of a heavy chain. I've never been into one of these transmission so I'm not completely sure what to make of it. Any help at all would be greatly appreciated. Thanks. I've also attacted a link to a youtube video I made, please turn up your sound. https://youtu.be/a8wX_CZfZss

Short answer, no chains, not much going on in there but a few gears

Considering that your friend asked you to replace the bearings and bushings in the electric motor, it’s likely that they’ve been experiencing some noise, vibration, or performance issues, common symptoms that can often be traced back to worn or damaged motor components. However, given the unusual feeling you noticed when spinning the transmission shaft, it’s possible that the problem isn’t just isolated to the motor but could extend to the transmission or rear axle components as well.

To help you get a better understanding, I’ve included some diagrams of the rear internals, which should give you a clearer picture of what’s happening inside the transmission. If the motor repair alone doesn’t resolve the problem, I’d recommend taking a closer look at the rear end. Specifically, inspect the input shaft and its bearings for any signs of wear or damage. If these components are worn, they can cause slack or play in the system, which could lead to the symptoms your friend has been experiencing. Replacing these parts might be necessary to fully restore smooth operation.

These components are known to be common points of failure, especially if the cart has been in use for a while. When bearings or the input shaft start to go bad, they can cause unusual noises, vibrations, or a lack of smoothness when the shaft is spun, which might explain the sensation you felt when you changed directions. If you have any questions or need further information feel free to ask!
