Frequently Asked Questions

Which seal kits fit the Case W18B loader hydraulic cylinders?

Broken Tractor carries seal kits listed for the Case W18B, including the Hydraulic Cylinder Seal Kit (SKU 1543273C1) and the Seal Kit for W20C cylinders (SKU G109499), both of which show W18B in their fitment. Because seal kits are matched to a specific cylinder bore and rod diameter, verify those dimensions before ordering. If you are unsure which kit matches your cylinder, our parts team can help confirm fitment.

What is included in a Case W18B hydraulic cylinder seal kit?

Kit contents vary but generally include piston seals, rod seals, gland seals, and O-rings depending on the specific kit. These cover lift, tilt, and steering cylinder rebuilds on the W18B. Check the individual kit listing to see exactly which seals are included.

Do I need special tools to rebuild a Case W18B loader cylinder?

Yes, rebuilding hydraulic cylinders usually requires a spanner wrench to remove the gland and a seal installer to seat new gland seals without damage. Broken Tractor offers the Case Hydraulic Spanner Wrench (SKU CAS-1456A), the Gland Seal Installation Tool Kit (SKU CAS-1457), and a complete Rebuild Tool Kit (SKU BT-CASE-CYL-TOOL-KIT). These tools fit Case backhoe and loader cylinders.

How do I make sure I order the right seal kit for my W18B?

Measure the cylinder bore and rod diameter first, since seal kits are sized to those dimensions rather than to the machine alone. Matching the tube or part number stamped on the cylinder is the most reliable way to confirm fitment. If you still need help, call our parts team at (800) 909-7060.

Can I replace just the piston instead of buying a full seal kit?

Broken Tractor carries a Hydraulic Cylinder Replacement Piston (SKU G100438) for select Case cylinders, which can be ordered separately from a seal kit. Confirm that the piston fitment matches your specific cylinder before ordering. For a full rebuild you may still want a seal kit to renew the rod, gland, and O-ring seals.
