Hi Group thanks for all the great tips.
The Bowser motor by itself now runs pretty quiet.
With the motor attached to the chassis and the basic drive train assembled, I get noise going forward but almost silence in reverse.
I've tried shim washers under the motor to change the gear mesh but no big changes in noise.? Should I try washers under both the front and rear motor mounting points at the same time?
Maybe noise is coming from the axles turning in the bearings?? I see some play when the wheels are turning.
I wish I had a nice power supply setup with a current meter, maybe down the road.? For now I'd be happy to tune the motor by ear so that the noise forward equals the noise in reverse,
Any tips?
