Description
Rotary FC537-12T Hydraulic Cylinder Seal Kit for SM90, AR90, SM91 – Texas Cylinder
Use this seal kit when your Rotary 4-post lift cylinder is leaking hydraulic fluid. Before ordering, verify your cylinder is a Texas Hydraulics unit – not a Pacoma (Massey Ferguson) cylinder. Texas Hydraulics cylinders typically have a clevis end on the anchor side (opposite the shaft) and will be stamped with a “T” or “TXT” followed by numbers on the cylinder housing. Cylinders stamped “Pacoma” or “Made in Germany” require a different seal kit (FC537-12MF).

Fitment & Ordering Notes
Verify your cylinder before ordering. Texas Hydraulics cylinders on these 4-post lifts typically have a clevis end on the anchor side of the cylinder (where it attaches to the lift). Look for a “T” or “TXT” stamp on the cylinder housing. If your cylinder reads “Pacoma” or “Made in Germany”, this seal kit will NOT fit – a Massey Ferguson / Pacoma kit (FC537-12MF) is required. Cross-reference is FC537-12TH. If unsure, call 866-902-6060 before ordering.
Additional Product Information
Our seal kits come in a sealed clear bag. Warning: Do not open bag until you verify you have the right seal kit once your cylinder is torn down. Simply remove your old seals from your cylinder and match them up by holding them next to new seals in bag. If they appear similar inside and outside diameter then you have the correct seals. If you are not sure please call us before opening the bag. We will not accept returns on open or used seals because you did not verify fitment first. Call our customer service hotline at 866-902-6060 if you need help identifying which seal kit is best for you.
