Noisy gears are from poor dimensional tolerancing meaning the parts are not made to print specifications so they are essentially wearing on each other hence the noise.


Wasn't the 833 18spline known to be noisier then the 23spline?
So by your statement: was the 18spline intentionally made "poorly"?


The 18 spline is noisier because of the pitch of the gear teeth is different than the 23 spline.


Seems some think these metal gear boxes should be as quiet as say some nylon gear gismo.
