Adjusting Gear Mesh

Incorrect gear mesh is the most 

common cause of stripped spur 

gears. Gear mesh should be 

checked and adjusted anytime 

a gear is replaced. To set the 

gear mesh, cut a narrow strip 

of notebook paper and run it 

into the gear mesh. Loosen 

the motor screws and slide the 

motor and pinion gear into the 

spur gear. Retighten the motor 

screws and then remove the 

strip of paper. You should be 

able to run a fresh strip of paper 

through the gears without binding them.
