Frequently Asked Questions

Which final drive fits a Cat E70B excavator?

Broken Tractor carries several final drives listed for the Cat E70B, including part numbers 099-6472, 099-6480 and 102-6947. The 099-6480 is offered as a final drive with sprocket. Because the correct unit can depend on your machine's serial number, match the part number on your old final drive or call (800) 909-7060 so the parts team can confirm fitment.

What final drive part numbers fit a Cat E110B excavator?

We carry three final drives listed for the Cat E110B: 099-5351, 1R5271 and 1R8942. Since more than one version fits the E110B, compare the part number stamped or tagged on your existing final drive before ordering. If you cannot find a number, confirm with our parts team using your machine's serial number.

Is the Cat E120 final drive the same as the E120B final drive?

No, Broken Tractor lists separate final drives for these two models. Part number 096-9403 fits the Cat E120, and part number 1R5128 fits the Cat E120B. Check your machine's model and serial number tag so you order the correct unit.

Does the Cat E300B final drive also fit the EL300B?

Yes, the final drive we carry under part number 1R6921 is listed to fit both the Cat E300B and the EL300B excavator. Match the part number on your current unit to be sure it is the right replacement for your machine.

Do Cat E Series excavator final drives come with a sprocket?

Some do. Broken Tractor offers both final drive gearboxes and complete final drive assemblies with sprocket options for Cat E-series excavators, such as the 099-6480 final drive with sprocket for the E70B. Check each product listing to see whether the sprocket is included before you order.
