Frequently Asked Questions

What boom cylinder fits a Cat 416D backhoe?

Broken Tractor carries two complete boom cylinders listed for the Cat 416D: part 6E0274, which also fits the 416B and 416C, and part 152-9148, which also fits the 420D, 428D, 432D, 438D and 442D. Because more than one cylinder is listed for the 416D, fitment can depend on your machine's serial number and configuration. Match the part number on your old cylinder, or call (800) 909-7060 so the parts team can confirm the right one before you order.

Is there a boom cylinder seal kit for the Cat 416B and 416C backhoe?

Yes, we carry seal kit 703391 for the Cat 416B and 416C. We also offer seal kit 2418924, which fits the 416B, 416C, 416D, 424D, 428B, 428C and 438C. Compare the part number on your cylinder against these kits to choose the correct one.

Are Cat backhoe boom cylinder seal kits the same across the 416, 416B, 416D and 416E?

No, boom cylinder seal kits are generation-specific, so confirm the series and suffix letter on your machine before ordering. For example, kit 645355 fits the original 416, kit 703391 fits the 416B and 416C, kit 2350972 fits the 416D and 424D, and kit 2959891 fits the 416E, 416F, 415F2, 416F2, 422E and 428E. Matching the kit to your exact model and cylinder part number helps you get the right seals the first time.

What boom cylinder parts are available for the Cat 420E and 420F backhoe?

Broken Tractor offers complete boom cylinder 2107076 for the Cat 420E, 420F, 420F2, 432E, 434E and 444F2. For rebuilding an existing cylinder on those machines, seal kit 2959893 fits the 420E, 420F, 420F2, 432E, 434E and 444F2. Check the part number on your current cylinder to confirm the match.

Should I replace the whole boom cylinder or rebuild it on my Cat backhoe?

Both options are available. A complete boom cylinder assembly is a direct replacement, while a seal kit lets you rebuild your existing cylinder. We also carry individual components such as boom cylinder rod assemblies (including 6E1522, 1595848, 4T7011 and 2764005) and cylinder tube 2063629 for the 416D, 420D, 428D, 432D, 438D and 442D, so you can replace only the parts you need.
