Frequently Asked Questions

What final drive fits a Cat 307 mini excavator?

Broken Tractor carries several final drives for the Cat 307 family, and the right one depends on your model letter. For the 307 there are part numbers 102-6410, 102-6420, 102-6460 and 102-6470, while the 307B uses 148-4567 (also fits the 308B) or 148-4736. For the 307D we offer final drives with sprocket under 288-5125, 352-9022 and 366-9777, so match the part number on your current drive before ordering.

Does a Cat 308 final drive come with a sprocket?

Some of the Cat 308 final drives we carry are sold with a sprocket. Part numbers 288-5125 and 352-9022 are final drives with sprocket for the 307D and 308D, and 366-9777 fits the 307D, 308D, 308E, 308E CR and 308E SR. For the 308E2 CR we offer the 417-1103 final drive kit, so check each product title to see exactly what is included.

How do I find the right final drive for my Cat 304.5?

The best way is to match the part number stamped on or listed for your existing final drive, because more than one part number fits the Cat 304.5. We carry 163-6947, 171-0503 and 199-5148 for the 304.5, and correct fitment can depend on your machine's serial number. If you are unsure which one you need, call (800) 909-7060 and the parts team can help confirm it.

What final drive fits a Cat 305C CR excavator?

We offer the 282-1533 final drive gearbox for the Cat 305C CR, plus the 363-9337 final drive gearbox, which also fits the 305.5D, 305.5D CR and 305.5E. For other 305 models, we carry 205-0470 for the 305 SR, 417-1114 for the 305E2 CR and 417-1115 for the 305.5E2. Confirm your exact model and part number before ordering, since these drives are not interchangeable across every 305 variant.

What final drive fits a Cat 301.5, 301.6 or 301.8 mini excavator?

Broken Tractor carries final drives 144-5196 and 209-6663, which both fit the Cat 301.5, 301.6 and 301.8. The C series uses different parts: 242-1153 fits the 301.6C and 301.8C, and 381-3144 fits the 301.4C. We also offer the 399-2903 final drive gearbox for the 301.7D.
