The Rotary FA2126 replacement part is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-9766-21, 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 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-9766-21 Brand: Rotary Type: Genuine OEM replacement part We are not a catalog that happens to list lift parts — our field techs install, inspect, and repair automotive lifts every week, and the parts on this site are the ones that come off our own service trucks. That changes what you get with the order. When you are not sure this is the right part, you can send a photo of your lift’s data tag and the failed part and get an answer from someone who has had that exact assembly apart. And when you hit something mid-job that the manual does not cover, the phone gets answered by people who have been under the same lift with the same wrench. 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.

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. The habit our techs are trained into applies here: when you finish a repair, run the lift through full cycles — all the way up, onto the locks, all the way down — and watch and listen the whole way. Leaks, rubbing, scraping, and locks that engage late all show themselves in the first three cycles if you are paying attention, which is a much better time to find them than under the next customer vehicle. If you get into the job and find more wrong than you expected, stop and reassess rather than improvising a way through — call us if you want a second opinion. Half-finished lift repairs are more dangerous than the original failure, because now the lift looks fixed. Why buy your Rotary replacement part from Auto Lift Services We install, inspect, and repair Rotary lifts every week — the ALS-9766-21 is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302. We confirm the right part for your lift's serial and production year before you order. Every part ships as genuine Rotary — no aftermarket substitution unless you specifically ask for an aftermarket equivalent. If you also need companion wear items — cables, sheaves, seals, hardware — for the same repair, use our parts lookup and we will build the whole kit for your lift so you order once and finish the job.
