The Rotary FA2154 replacement part is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-9766-37, 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 replacement part 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-9766-37 Brand: Rotary Type: Genuine OEM replacement part This is a manufacturer-spec replacement part for the lift it was designed for — same dimensions, same material, same fit as the part that came off. That matters more on a lift than on most equipment, because lift parts do not work in isolation: a part that is close-but-not-quite transfers its error into whatever it bolts to, rides on, or seals against. A knock-off that is a few thousandths off might install fine and then wear its neighbors for the next five years. When you order to the published spec, the part drops in and the rest of the lift never knows anything changed. Related parts for this lift The parts below are commonly ordered alongside this one — cables, sheaves, seals, and hardware wear on similar schedules, and most repairs go faster when the whole set is done in one visit.

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. Before you install the replacement, compare it side by side with the part you removed — length, bore, thread, and mounting pattern should match exactly, not approximately. If the old part is worn out of shape, measure against the mounting points on the lift instead. A mismatch caught on the bench costs you a phone call; a mismatch caught after installation costs you the job twice. Never modify a lift part to make it fit — no drilling out holes, no grinding down shoulders, no washers-as-spacers improvisation. A part that needs persuasion is the wrong part, and a modified part on a machine that holds vehicles over people is a liability with your name on it.
