Frequently Asked Questions
What seal kits are available for the Case CX350D LC boom, dipper arm, and bucket cylinders?
Broken Tractor carries individual seal kits matched to each cylinder position on the CX350D LC. For the boom cylinder we offer SKU LZ012090, for the dipper arm cylinder SKU LZ011310 and LZ012100, and for the bucket cylinder SKU LZ010940 and LZ012110. Ordering by cylinder position and part number ensures you get the correct kit for your machine.
What is included in a Case CX350D cylinder seal kit?
Each seal kit includes rod seals, piston seals, wipers, and backup rings for the matched cylinder. These are the wear items needed to rebuild the cylinder and stop hydraulic leaks. Kits are matched to individual cylinder positions, so confirm you are ordering for the boom, dipper arm, or bucket cylinder.
Do the CX350D LC seal kits also fit the CX350D LC LR long reach model?
Some kits are matched to the LR configuration. The dipper arm cylinder seal kit SKU LZ011310 is listed to fit the CX350D LC LR, while other kits are listed for the CX350D LC. Because fitment can vary by cylinder and machine configuration, match the part number to your cylinder or confirm with our parts team before ordering.
How do I know which bucket cylinder seal kit is right for my Case CX350D?
Broken Tractor offers more than one bucket cylinder seal kit that fits the CX350D LC, including SKU LZ010940 and SKU LZ012110. The correct kit depends on your cylinder bore, so match the part to your cylinder rather than the machine model alone. If you are unsure which kit matches your cylinder, call our parts team at (800) 909-7060.
Should I rebuild my CX350D cylinder with a seal kit or replace it?
If the cylinder barrel and rod are still in good condition and the problem is leaking or lost hydraulic performance, a seal kit lets you rebuild the cylinder rather than replace it. Our seal kits include the rod seals, piston seals, wipers, and backup rings needed to restore sealing. Match the kit to the boom, dipper arm, or bucket cylinder position and to your cylinder bore for the correct fit.
