The Rotary FC576 replacement hardware is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7531-21, 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 hardware 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-7531-21 Brand: Rotary Type: Genuine OEM replacement hardware Fits: RJ9000-1, SP88, SP98 Lift type: 2-post lift Hardware is where lift failures are born. A pin that has worn oval lets its sheave run crooked; the crooked sheave saws at the cable; and a five-dollar pin has now written a quote for cables and sheaves. Springs lose tension and a lock pawl stops returning. A bushing thins out and the clunk everyone ignores becomes the slop that rounds off the bore it sits in. None of these parts fail dramatically — they just get a little loose, a little rounder, a little weaker, and pass the damage up to whatever they located or supported. Replacing hardware at the first sign of wear is how the expensive parts on a lift get to live out their full lives. 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. Wheel Bearing - Rotary FC5905-3 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. When hardware comes out, read it. An ovaled pin means its bore is probably ovaled too — check the hole, not just the pin. A stretched spring means something was binding for it to fight. Bright metal dust around a bushing or bearing means it has been grinding, so inspect what it rides in. New hardware in a worn bore is a short-term repair with a long-term invoice. Never reuse a bent pin, a stretched spring, or a mushroomed piece of hardware because it still technically fits — and never substitute generic hardware-store fasteners for load-bearing lift hardware. Grade and dimensions exist for a reason on a machine that holds vehicles in the air.
