The Rotary ML10-166 replacement hardware is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7540-38, 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-7540-38 Brand: Rotary Type: Genuine OEM replacement hardware Nobody budgets for a washer. That is exactly how a bay ends up dead for three days — the big components get stocked and scheduled, and then the lift goes down over a pin, a clip, or a spring that nobody thought to have on the shelf. Hardware is the highest-leverage inventory in lift maintenance: the unit cost is trivial, the failure mode is a stopped bay, and the lead time is the same freight wait as any other part. When you order the hardware that failed, order its twin on the other side of the lift too — both sides carry the same hours, so the second failure is already scheduled whether you planned for it or not. 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.

Here's how to check Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork. Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram. Check the mirror position of whatever failed. Lifts are symmetric machines: the same pin, spring, or bushing exists on the other column or the other end of the crossbeam, with identical hours on it. If one side measured worn, the other side is close behind, and the labor is already paid while the lift is apart. Also inspect the hardware you had to remove for access — disturbed fasteners deserve a look before reuse. Waiting on a hardware part is not a reason to run the lift without it. A lift missing a retaining clip or running a known-broken spring is out of service until the part arrives — the couple of days of patience is cheaper than what an unretained pin lets go of.
