The factory recommends hand tightening your replacement sprocket to the appropriate torque requirement set by Bobcat® to avoid damage to the drive sprocket or travel motor. Sprockets and rubber tracks should always be changed together at the same time to maximize the lifespan of your undercarriage parts
