The Rotary N332 seal kit is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7519-22, 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 seal kit 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-7519-22 Brand: Rotary Type: Genuine OEM seal kit Fits: A10i, A10i EH-1, A10i EH-2, A8i, A8i EH-1, A8i EH-2, S10i, S10i EH-1, S10i EH-2, S10i EH-4 Lift type: 2-post lift The power unit bundles the motor, pump, reservoir, and valves into one hangable box, usually bolted to a column or a pump stand. Press up and the motor spins the pump, which draws fluid from the reservoir and sends it to the cylinder; release, and the dump valve routes it back. The single spec that matters most is voltage — 110 versus 220 — because the wrong one turns the whole unit into a paperweight. Hydraulic parts fit by the numbers, and the numbers are unforgiving. A cylinder has to match working length and port type; a hose is spec'd by inner diameter, pressure rating, and end fittings; a power unit lives or dies on voltage. Even seal kits differ by who built the cylinder — the same lift model can carry two cylinder brands with different seal profiles. Order to the actual part, not the lift name.

Isolate whether the leak is internal or external, then service or replace the valve and confirm the lift holds height afterward. The step-by-step guide lays out how to trace it.

Signs of a hydraulic problem The fast hydraulic triage: puddle on the floor is an external leak (find it uphill); a lift that won't hold overnight is an internal leak (cylinder or valve); a spongy feel is air or a piston seal; milky fluid is water (service it); a slow or noisy raise is pump, fluid, or air. Match the symptom to the part before you throw a cylinder at a problem that's really a five-dollar washer. Parts commonly replaced at the same time One trip up, one refill, one bleed: order the companion hydraulic parts with this one. A seal kit alongside a cylinder, a fresh hose, and the correct oil turn a partial fix into a finished job. Tell us what lift you have and we will build the kit so nothing is left to fail next. Hydraulic fluid The usual fill is ISO-32 hydraulic oil, with some legacy lifts running Dexron ATF; confirm which your lift uses before topping off and keep the two separate. Bleed after filling and check the level again once the air is out — and see your manual for the exact capacity, which is model-specific. Safety notes Pressure and cleanliness are the two rules. Bleed the system completely so there is no air to compress, keep contamination out of every open port, and prove the lift holds at full height with no drift before it sees a vehicle. If you are not certain the bleed is complete, do it again — this is not the place to guess. Before you order Ordering tip: hydraulic parts are matched to the lift's pressure and geometry, so read the model and serial off the plate and, for hoses and cylinders, have the old part's dimensions. Plan to replace the oil and bleed the system as part of the job, and add a seal kit if you are opening the cylinder anyway. Check your lift's serial before ordering The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift. Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
