Frequently Asked Questions

What Cat backhoe hydraulic cylinders does Broken Tractor carry?

Broken Tractor carries boom, stick, bucket, stabilizer, loader lift and crowd cylinders for Caterpillar backhoe loaders, in both new OEM-equivalent and remanufactured versions. Coverage spans the 416, 420, 430, 432, 434, 442, 444 and 450 series, including models like the 416F, 420F2, 430F2 and 450F. We also offer fast shipping.

How do I rebuild a Cat backhoe hydraulic cylinder, and what parts do I need?

A rebuild usually comes down to replacing worn seals and, if it is damaged, the cylinder tube, and Broken Tractor carries both. Our Caterpillar hydraulic cylinder seal kit (SKU 646409) fits the 416, 416B, 416C, 426 and 426B backhoes. For tube replacement we carry Cat cylinder tubes 2627051, 2120929 and 9T4009, each fitting specific backhoe models.

How do I find the right hydraulic cylinder for my Cat backhoe?

Match the Cat part number or your machine serial number, because fitment can change within the same model. Before ordering, confirm the bore size and stroke length against your serial number, and check whether your machine has a standard or extendable stick. If you are unsure, call (800) 909-7060 and our parts team can confirm fitment by serial number.

Which Cat backhoe models does the 9T4009 hydraulic cylinder tube fit?

The Cat 9T4009 cylinder tube fits backhoe models including the 422E, 424D, 426, 426C, 428, 428B, 428C, 428D, 428E, 430D, 432D, 432E, 434E, 436C, 438C, 438D, 442D, 442E and 444E. Because cylinder fitment can vary by serial number, compare the part number on your existing tube before ordering.

What hydraulic cylinder tube fits a Cat 420E or 420F backhoe?

Broken Tractor carries two Cat cylinder tubes for these machines. Part 2120929 fits the 420E, 420F, 420F2 and 444F2, and part 2627051 fits the 416E, 420E, 430E, 416F2 and 420F2. Since both fit the 420E, match the part number on your old tube or check your serial number to get the correct one.
