How to Change Buttons (wear pads) on a 4x2 Gator Secondary Clutch
Hello All - Is there a way to change the clutch buttons (wear pads) on a 1990's 4x2 Gator secondary clutch without removing the entire clutch assembly from the shaft and taking it apart? It looks like half the buttons can be replaced easily as there is nothing pressing against them but the other half are pressed against the engaged part …
