Frequently Asked Questions
What seal kits are available for the Case CX170E LC excavator cylinders?
Broken Tractor carries separate seal kits for the boom, dipper arm, and bucket cylinders on the Case CX170E LC. These include the bucket cylinder seal kit (SKU LZ010810), the boom cylinder seal kit (SKU LZ010870), and the dipper arm cylinder seal kit (SKU LZ011000). Choose the kit that matches the cylinder function you are rebuilding.
What is included in a Case CX170E cylinder seal kit?
Each kit is a complete seal package with O-rings, wipers, and back-up rings for rebuilding the cylinder it covers. These are new replacement seal kits matched to the boom, arm, or bucket circuit. Order the kit that corresponds to the specific cylinder you are servicing.
Does the Case CX170E boom cylinder seal kit fit other CX models?
Yes, the boom cylinder seal kit (SKU LZ010870) fits the CX160C, CX160D LC, CX170E LC, and CX190E LC. If you are unsure whether your machine matches, confirm the part number against your cylinder or check with the parts team before ordering.
Which arm cylinder seal kit fits the Case CX170E LC?
Both the dipper arm cylinder seal kit (SKU LZ011000) and the CX arm cylinder seal kit (SKU MMV80200) fit the CX170E LC. Fitment can vary by cylinder position and serial number, so match the part number to your cylinder to be sure you get the correct kit.
Should I rebuild my Case CX170E cylinder or replace the whole cylinder?
A seal kit lets you rebuild a hydraulic cylinder that is leaking due to worn seals rather than replacing the entire cylinder. Broken Tractor offers new replacement seal kits with O-rings, wipers, and back-up rings for the boom, arm, and bucket cylinders on the CX170E LC. If the cylinder rod or barrel is damaged, seals alone will not correct the problem.
