Brake Adjustment 

 

The brakes are the next thing that should be checked and adjusted before letting a child ride the 

ATV; and an adult should check the brakes before each use. Start by pushing the unit and 

depressing the brake peddle and make sure that the brakes will stop the ATV with  little effort, if 

not turn the adjusting nut clockwise (see picture below) to put more stopping power but, roll the 

ATV to make sure the brake is not dragging or lift the rear of the ATV and roll the rear tires. If 

the brake is dragging it could cause premature failure of the brakes, so turn the adjusting nut 

counter clockwise to put less pressure. There should be an inspection plug on the flat side of the 

drum (see picture). Once the plug is removed you can inspect the lining on the brake shoe, and 

check for any foreign material.  

 

  

 

 

 

 

 

 

 

 

 

 

 

Clutch Adjustment 

 

With the centrifugal clutch it will need to be adjusted as it wears. There is an external 

adjustment screw that will either put more or less tension on the clutch disk. By holding the stud 

with a screw driver and 

loosening the jamb nut. 

Slowly turn the stud 

counter clockwise until 

there is resistance is 

felt. Then turn the stud 

1/8 turn clockwise. 

Tighten the locknut to 

11ft.lb. torque. 

NOTE: 

Turning the adjusting 

stud clockwise will 

increase the free play 

(more slipage), and 

counter clockwise will 

decrease the clutch free 

play (less slippage).
