Rotary FJ7664 Replacement Hydraulic Cylinder for 2-Post and Inground Rotary Lifts
This is a single replacement hydraulic cylinder for many Rotary 2-post and inground lift models. It meets or exceeds factory specifications. Before ordering, confirm the cylinder stamped number on your existing cylinder: ALL Rotary cylinders are stamped with their part number on the outer tube / housing, typically approximately 6 in. from the bleeder screw at the top. Your cylinder must read “FJ7664” or “N310” to use this replacement. Some lift models above have newer versions that use a different cylinder – check the stamping, not just the model number.

Fitment & Ordering Notes
This cylinder fits Rotary lifts with a model suffix of -200 or earlier ONLY. If your lift model suffix is -300 or higher, this is NOT the correct cylinder – order N380 / N342 instead. Verify by reading the stamped number on the cylinder outer tube (approximately 6 in. from the top bleeder screw): it must read “FJ7664” or “N310”. When replacing a cylinder, flush and clean the hydraulic reservoir and system before installing the new cylinder to prevent premature failure.
