Replacing Brake
Shoes G9901 &
G9902
Replace the brake shoes when they no lon-
ger stop the spindle. Due to the time and labor
involved, you may want to replace the belts at this
time as well.
Call Grizzly Customer Service at (800) 523-4777
to order the brake shoes (Part Number
P9901318).

Separate the spindle speed range lever
assembly from the transmission cover plate
