Frequently Asked Questions
What cylinder seal kits fit a Case CX75C excavator?
Broken Tractor carries boom, dipper (arm), and bucket cylinder seal kits for the Case CX75C and CX75C SR Tier 4 excavators. Select components also fit the Case CX80C. Fitment can vary by model and serial number, so match the part number on your cylinder or confirm with our parts team before ordering.
Why does the boom drift down on a Case CX75C excavator?
Boom drift is commonly caused by internal bypass, where worn cylinder seals let hydraulic oil slip past inside the cylinder. Installing a new seal kit restores proper sealing and stops the drift. The same problem can show up in the dipper or bucket cylinders, and we carry seal kits for all three.
Does the boom cylinder seal kit LZ012020 fit the Case CX75C SR?
Yes, boom cylinder seal kit SKU LZ012020 is listed to fit the Case CX75C SR Tier 4 and the Case CX80C excavators. If you run a standard CX75C or are unsure which version you have, check your model and serial number first. Call (800) 909-7060 and our parts team can help confirm the right kit.
Who makes the Case CX75C excavator seal kits sold by Broken Tractor?
Our Case CX75C seal kits are made in the USA by Hercules or Bulldog Hydraulics. They are manufactured to OEM specifications, so they are built to match the original sealing performance of your boom, dipper, and bucket cylinders.
