Frequently Asked Questions
How do I know which rear axle hub fits my Komatsu backhoe?
Match the part number stamped on your old hub to confirm the correct fit, since lug patterns and stud counts differ across models. If you are unsure, our parts team can help you verify by serial number. Call (800) 909-7060 for assistance.
What does the rear axle planetary drive shaft do?
The planetary drive shaft transfers power through the planetary gear set at the wheel end to drive the rear wheels. A worn or cracked shaft can cause noise, vibration, or loss of drive. Replacing it restores proper power transfer through the rear axle.
Are these rear axle parts new or used?
We carry both new and quality used Komatsu backhoe rear axle parts depending on the component and availability. Each listing notes the condition so you can choose what fits your repair and budget.
Can I replace just the hub or planetary shaft without rebuilding the whole axle?
Yes, in many cases you can replace individual components like the hub or planetary drive shaft without a full axle rebuild. Inspect the surrounding bearings and seals while you have the axle apart to avoid a repeat repair.
