The Rotary FJ294-3 hydraulic cylinder is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7515-54, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary hydraulic cylinder from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.
Specifications
- Part number: ALS-7515-54
- Brand: Rotary
- Type: Genuine OEM hydraulic cylinder
Seals and hoses age on two clocks at once: cycles and years. A cylinder seal wears from the miles the rod travels; a hose gets brittle just sitting in shop heat and cold. Run dirty fluid and you speed both up, because grit scores the barrel and the rod and shreds seals from the inside. Most lifts that pump every day start weeping a seal somewhere in the eight-to-fifteen year range.
The hydraulic side of a lift is a closed loop: the power unit's motor drives a pump that pushes fluid from the reservoir, through a hose and fittings, into a cylinder that does the lifting, while a lowering valve meters it back to tank on the way down. Every part in that loop either moves fluid, holds pressure, or seals it in. When one link weeps or won't hold, the whole lift feels it.

Replacing your hydraulic cylinder
Replacing a power unit means confirming the voltage matches, killing power at the breaker, bleeding the hydraulic pressure, then transferring the lines and wiring to the new unit and refilling with the correct fluid. Getting the voltage and the fluid right is what separates a working swap from a paperweight. The complete procedure covers each step in order. Full step-by-step: how to replace a 2-post lift cylinder.
Find the right part for your lift
Want to be sure before you buy? Pull the model and serial off your lift's plate and open our Rotary parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it for you.
Signs of a hydraulic problem
Check for drift-down as the clearest internal-leak test: raise the lift, shut it off, and time how long it holds. A properly sealed system holds height for days. Noticeable sag in a few hours points to the lowering valve not seating, a failed check valve, or a piston seal passing fluid — cracking the cylinder and watching whether it sags with the valve closed isolates which.
Parts commonly replaced at the same time
The parts near a hydraulic failure are usually next in line — seals that are hardening, a hose that is cracking, fittings that seep. Do them together while the system is open and bled. We will match the seal kit, hose, and oil to your lift so you are not chasing the same leak in a month.
Hydraulic fluid
Most 2-post and 4-post lifts run hydraulic oil equivalent to ISO-32; some older units were filled with Dexron ATF. Check what your lift currently uses and do not mix the two — and defer to your lift's installation manual for the exact fill capacity, since it varies by model.
Safety notes
A hydraulic lift that drops or drifts almost always traces to air or a failed seal, both of which are preventable. Relieve pressure before opening anything, bleed until the stream runs solid, and never sign off a repair with the lift drifting even slightly at full height. Locks stay engaged while you work.
Before you order
Before ordering, confirm your lift's model and serial and, for a cylinder or hose, the exact length or fitting configuration — these change across production runs. If you only need to stop a leak, a seal kit may be the smarter buy than a whole cylinder; call and we will help you decide before you spend.
Confirm this is the right part before you order
Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits.
If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
Why buy your Rotary hydraulic cylinder from Auto Lift Services
We install, inspect, and repair Rotary lifts every week — the ALS-7515-54 is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302 — and every part ships genuine, no aftermarket substitution unless you ask for it.
About this pal5e cylinder rotary
The pal5e cylinder rotary is a direct-fit replacement engineered to restore original manufacturer performance on the lift model it services. Every piece we ship carries the exact dimensional and material specifications the OEM published for that application. Fitment on this component is critical: it interfaces with adjacent hardware in ways that any deviation from spec can drive premature wear on nearby parts or trigger the lift's mechanical safety systems into an unexpected condition. Shops that source this from us instead of a generic aftermarket substitute consistently report zero fitment issues on first-time installation.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the pal5e cylinder rotary correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Placing an order online is the fastest path — add to cart, check out, done. If the shop needs a purchase order, net-30 terms, or a formal quote for a fleet-service contract, our accounts team handles those via email at [email protected] or by phone at 800-674-9302. Volume pricing on the pal5e cylinder rotary kicks in at 10+ pieces on the same order for common wear items. Ask about the volume rate specifically before you check out — many fleet buyers stock 6-12 pieces at a time and the discount is meaningful over that shelf life.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the pal5e cylinder rotary is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Fitment on the pal5e cylinder rotary is verified against the lift serial number when the order comes in. Even inside one manufacturer's catalog, a lift model built in one production year can carry subtle revisions from the same model built two or three years later. Sending us the lift serial number when you place the order — either in the order notes or in a follow-up email — lets us verify the piece against that specific serial's parts list. That five-minute step catches revision mismatches before shipping and prevents the delay of an incorrect delivery.
