The Rotary N410 column component is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7528-91, 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 column component 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-7528-91 Brand: Rotary Type: Genuine OEM column component Fits: A8i, A8i EH-1, A8i EH-2, SPOA7 200 Series, SPOA9, SPOA9 EH-1 200 Series, SPOA9 EH-2 200 Series, SPOA9 EH-4 200 Series Lift type: 2-post lift Adapters take a beating because they're the parts techs handle every day — stacked, swapped, dropped, and driven over. A bent lip, a mushroomed top, or a cracked weld on a frame-cradle adapter comes from that daily handling as much as from load. Because they're small and get tossed in a pile, they're easy to grab without a second look — which is exactly how a bent one ends up under a car. What lifts this column component fits This column component fits the lift models below. Click a model to open its visual parts breakdown — the exploded drawing with every part numbered, so you can confirm this is the right part for your exact lift before you order. A8I — see the exploded parts breakdown for this lift SPOA7 — see the exploded parts breakdown for this lift SPOA9 — see the exploded parts breakdown for this lift Replacing your column component Replacing column hardware — anchors, arm-pin retainers, slide blocks, fasteners — is about restoring the tight, no-play fit the structure was built with. Use the correct grade and torque, and confirm the column sits flat and solid to the floor afterward. The complete procedure lays out what to check and in what order. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it. Find the right part for your lift The surest way to get the right part is to work from your lift's own breakdown. open our Rotary parts lookup, choose your model, and every part is mapped on the drawing with its number and price. If you cannot find the model plate, our guide to finding your model number explains where each lift type hides it, and our phone line is open if you want a hand. Signs this part is worn out Start with the pads. A good pad is thick, square, and grippy; a worn one is crushed flat, cracked through, torn at the edge, or hardened smooth so it no longer bites. If a pad is missing chunks, oil-soaked, or compressed past half its original height, replace it — a slick or crushed pad lets the vehicle's lift point slide right off the arm. Parts commonly replaced at the same time Smart to replace the group: contact points wear together, so pads, adapters, and their pins are best done in one pass. It keeps the lift level and the vehicle secure. We will build the matched structural kit for your model so you are not chasing one worn pad at a time. Safety notes Structural wear sneaks up: a pad flattens, a hole elongates, a ramp lip curls, and one day the vehicle is not sitting where it should. Treat these as safety parts, not cosmetics. Replace them before they let a load shift, and confirm every mounting point is tight and true before the lift carries weight. Before you order Before ordering, confirm your lift's model and serial and check how many of the part you need — pads and adapters usually go in sets of four, and replacing one worn one still leaves three worn. Match the old part's shape and mounting against what you order, and call if the fit is not obvious. 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.
