Frequently Asked Questions
Which final drive gearbox fits a Cat 320C excavator?
Broken Tractor offers several final drive gearboxes for the Cat 320C, including part numbers 1484695 (320C, 320C U), 114-1488 (320C, 322B, 322B L) and 191-2682 (320C, 325C, 325C MH, 325C FSM). The 320C L uses a different gearbox, part number 2276035, and the 320C U is also listed under 148-4695. Because the correct unit can vary by configuration and serial number, match the part number on your old final drive or call (800) 909-7060 to confirm fitment.
What final drive fits a Cat 320D or 323D L excavator?
For the Cat 320D, we carry final drive gearboxes 227-6035 and 353-0615, which also cover the 320D L. The 323D L can use 227-6035, 353-0611 or 353-0615, depending on the machine. Match the part number from your existing final drive or check with the parts team before ordering.
Which final drive fits a Cat 330B, 330C or 330D excavator?
For the Cat 330B and 330B L, Broken Tractor offers final drive gearboxes 114-1478 and 191-3241, plus 204-3649 for the 330B L. The 330C and 330D use part number 199-4579. Since more than one gearbox is listed for the 330B series, compare part numbers with your original unit to get the right match.
