Frequently Asked Questions

Which hydraulic cylinder fits my Komatsu PC200 excavator?

It depends on the generation and the cylinder position. We carry arm cylinder 205-63-03121 for the PC200-6 and arm cylinder 707-01-XZ840 for the PC200-7 and PC200-8. For PC200-6 bucket cylinders, we list both 205-63-X2131 and 205-63-03131, so match the OEM part number on your old cylinder before ordering.

Which arm cylinder fits a Komatsu PC220-6?

Broken Tractor lists two arm cylinders for the PC220-6: 206-63-03120 and 707-01-XX920, which is for early serial machines. Some PC220-6 applications are serial-range specific, so check your machine serial number and the part number on your current cylinder. If you are unsure which one fits, call (800) 909-7060.

Do Komatsu LC excavators use the same hydraulic cylinders as standard models?

In most cases, yes. Long-undercarriage (LC) variants usually share cylinder fitment with the standard models. For example, arm cylinder 707-01-XZ982 fits the PC300-7, PC300LC-7, PC300-8, PC300LC-8, PC350-7, PC350LC-7, PC350-8 and PC350LC-8. Always confirm by matching the OEM part number.

Are Komatsu excavator hydraulic cylinders sold new or rebuilt?

Broken Tractor offers both new and rebuilt OEM cylinder assemblies, depending on the application. For example, dipper arm cylinder 707-E1-00961 for the PC220-8, PC240-10 and PC240-11 is a rebuilt OEM unit. OEM Komatsu part numbers are cross-referenced so you can match the right cylinder for your machine.

Do you carry hydraulic cylinders for large Komatsu excavators like the PC2000-8?

Yes. We carry bucket cylinder 707-01-0K790 for the Komatsu PC2000-8 and arm cylinder 707-01-0K280 for the PC800-8. We also offer bucket cylinder 21M-63-02131 for the PC600-7. Fitment on large machines is model specific, so match the OEM part number before ordering.
