Frequently Asked Questions

What Case excavator models does the dipper cylinder seal kit (SKU 156002A1) fit?

The dipper cylinder seal kit fits the Case 9040 LR, 9040B LR, and 9050 excavators. It includes complete seals for rebuilding the dipper cylinder. If you are unsure whether it matches your machine, confirm the part number with our parts team before ordering.

Do you sell a replacement bucket cylinder for the Case 9050B?

Yes, Broken Tractor offers a new bucket cylinder assembly that fits the Case 9050 and 9050B excavators (SKU 173012A1). It is a new replacement component rather than a seal kit, so you install the full cylinder rather than rebuilding your existing one.

Should I rebuild my Case 9050 dipper cylinder or replace the whole cylinder?

For a dipper cylinder that is leaking but otherwise sound, the dipper cylinder seal kit (SKU 156002A1) lets you rebuild it with a complete set of seals. If the cylinder barrel or rod is worn or damaged, a new replacement assembly is the better option. Our support team can help you match the right part for your repair.

How do I make sure I order the right cylinder or seal kit for my Case 9050 excavator?

Match the part number to your machine and confirm fitment against your model, since some parts fit specific 9040 and 9050 series variants. The dipper seal kit covers the 9040 LR, 9040B LR, and 9050, while the bucket cylinder fits the 9050 and 9050B. For help matching hydraulic parts, call our parts team at (800) 909-7060.
