The Rotary FC147-9 replacement hardware is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7524-33, 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-7524-33 Brand: Rotary Type: Genuine OEM replacement hardware Fits: AR12, SM12 Lift type: 4-post lift Hardware is the easiest category to order wrong, because so much of it looks generic — a pin is a pin until it is an eighth of an inch short and the e-clip groove lands inside the bore. Lift makers change hardware dimensions between production runs without renaming the lift, so the part that fits a given model can split by serial range. Order from your lift’s data tag — model and serial — rather than from the model name or from a lookalike photo. If the tag is gone, the old hardware itself is the spec: measure it, or photograph it next to a tape measure and send it to us, and we will match it before it ships.

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. Measure the old part before you order and again against the new part when it arrives: overall length, diameter, groove and cross-hole locations, and thread size on anything threaded. On threaded hardware, run the nut on by hand first — if it fights, check for welding slag or damaged threads and clean them up with a file rather than powering the nut on and wrecking both parts. Close is not correct on load-bearing hardware. A pin that is slightly undersized hammers its bore oval; a bolt of the wrong grade shears under a load the right one shrugs off. If what arrived does not match what came out, install nothing and call — guessing is the one move with no good outcome.
