Frequently Asked Questions
What seal kits are available for the Case CX380E LC excavator?
Broken Tractor carries function-specific seal kits for the boom cylinder (SKU LZ012090), dipper arm cylinder (SKU LZ012100), and bucket cylinder (SKU LZ012110) on the CX380E LC. Each kit is matched to a single cylinder function so you can reseal only the cylinder that is leaking. All three also fit the CX350D LC.
What is included in a CX380E LC cylinder seal kit?
Each kit contains the rod seals, wipers, O-rings, and backup rings needed to reseal that specific cylinder. Contents are matched per cylinder function, so the boom, dipper arm, and bucket kits differ. These are new replacement seal kits intended to stop hydraulic leaks.
How do I know which seal kit I need for my CX380E LC?
Match the kit to the cylinder that is leaking, boom, dipper arm, or bucket, then confirm by part number. The boom kit is LZ012090, the dipper arm kit is LZ012100, and the bucket kit is LZ012110. If you are unsure which cylinder is affected, confirm the part number with our parts team before ordering.
Will a CX350D LC seal kit fit a CX380E LC?
Yes, the boom, dipper arm, and bucket cylinder seal kits we carry are listed to fit both the CX350D LC and the CX380E LC. Fitment can depend on your machine's serial number, so match the part number to your cylinder. You can verify compatibility with our parts team at (800) 909-7060.
Can I reseal just one cylinder instead of replacing the whole cylinder?
Yes, these are cylinder-specific reseal kits that let you replace the seals in a leaking boom, dipper arm, or bucket cylinder rather than the entire cylinder. Each kit includes the rod seals, wipers, O-rings, and backup rings for that function. Order the kit that matches the cylinder giving you trouble.
