Setting pinion gear adjustment

[Moab Bob]

I took of the stock 20 tooth pinion gear and install the 14 tooth gear. I just adjusted to motor till they meshed snuggly. Is there a certain clearence I should know about? The gear noise is audible, but I havne't been around anybody else's truck to know what is normal. I have the Honcho RTR with stock motor.

I like to set mine to where the mesh should be just loose enough to wiggle the spur back and forth without moving the pinion, or the thickness of a piece of paper in between the gears. Should be fairly quiet, unless mesh is too tight. Hope that helps.

insert a printing paper between the gears, the paper should not be torn by them.

I've always set my mesh by ear. I let the motor turn the drivetrain, and lock it in just at the point you can hear that all the strain is off the mesh. This puts the least strain on the motor, is quietest, and is least likely to result in stripped spurs because the teeth are engaged the maximum possible amount.

Thanks for the help. I loosened the motor and set the mesh by eye and "wiggle". I then tightened up and ran some paper through the gears. The gear noise really quieted down at low speeds, and at full throttle, it sounds like a well oiled sewing machine!
