GEAR MESH
1. Proper gear mesh is critical to achieve long life of your spur gear.
2. Install the pinion so it lines up fl ush with the spur.
3. Loosen the motor screws and lightly push the two gears together.
Proper mesh will give you full tooth engagement but not be so tight
that the gears bind. As a guideline, a good mesh is when you are
holding one gear and when you move the other, you can see zero or
just a very slight amount of gear lash*.
* Gear Lash is defi ned as the amount of clearance or slack between two gears.
