New undercarriage parts and rubber tracks are sold individually but we suggest replacing all of your worn parts at the same time.
This is the aftermarket drive sprocket for your Caterpillar 303.5 mini excavator.
Sprocket specifications:
Rubbertrax suggests changing sprockets and rubber tracks together as they are designed to wear together over time. The sprockets do not come with replacement bolts. You need nine bolts (12mm) to mount the sprocket.
