The Rotary FA5153-2 replacement part is the direct replacement for the Rotary lift it came off of. Cross-referenced as BA-1590-55, 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

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.

Ordering the right revision

Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct.

If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.

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.
