The Rotary FJ7497 sheave is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7503-37, 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 sheave 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-7503-37
- Brand: Rotary
- Type: Genuine OEM sheave
Cable length and end fittings are what make a tension part fit, and they vary more than people expect. Older asymmetric lifts ran a long cable and a short cable; some columns use a threaded stud end, others a button or wedge. Order by the lift's actual routing, not a guess, because a cable that's an inch off or ends in the wrong fitting won't tension right no matter how you adjust it.
A cable is only as good as the sheave it rides. The two parts wear as a system: a grooved or wobbling sheave chews the cable, and a corded cable grinds a fresh sheave. That's why techs who pull a lift apart for one usually replace both, along with the small lock-release cable that trips the pawls. Swapping a cable onto worn sheaves just starts the failure clock over again.

Replacing your sheave
Replacing a lift cable is straightforward hand-tool work, but the details decide whether the lift lands level afterward — routing each cable correctly over its sheaves, connecting the hard-to-reach end first, and setting the adjusting nuts so every lock clicks together. Before you cut the old cable off, lay the new one alongside it to confirm the length is right. Because a mis-routed or unequal set makes the lift arrive crooked, the full procedure is worth following start to finish. Full step-by-step: how to replace car lift sheaves.
Find the right part for your lift
Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Rotary parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you.
Signs a cable or sheave is worn out
Pay attention to the cable ends and fittings. The threaded stud where the adjusting nut rides is a common failure point — look for stretched, necked-down threads and cracks at the swage where the fitting is crimped to the cable. If the swage shows any gap or the wires are pulling out of the fitting, the cable is finished regardless of how good the middle looks.
Parts commonly replaced at the same time
Rarely is a tension part a solo job. A worn cable often means the sheaves it rides are grooved, and a failed sheave chews cables — so plan on doing them together. We can pull the matched cable set plus sheaves and pins for your exact lift so nothing gets missed and you are not back in there next month.
Safety notes
The whole reason a lift has redundant locks is that cables and sheaves are wear items that will eventually fail — your job is to replace them before they get there. Do not run a lift on a cable with broken strands or a sheave with a chipped flange, and never work under a load resting on tension parts you do not trust. Drop it to the locks first.
Before you order
Get it right the first time: note your lift's model and serial, count the cables in the set, and check the sheaves while you are at it. Ordering matched tension parts together saves a return and a repeat teardown. If you are unsure which length your lift takes, send a photo of the plate.
Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. 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.

About this fj7497 sheave rotary
Sourcing the correct fj7497 sheave rotary is not the spot a shop wants to gamble. This piece sits inside a load path the lift manufacturer engineered to specific tolerances, and a substitute that looks close but is off by even a small margin can transfer load onto a neighboring component that was not designed for it. We stock this exact part to the OEM specification the original manufacturer publishes, which is why techs who have been through a bad aftermarket cycle keep coming back to us for the same replacement whenever their next need comes up.
Technical specification & installation notes
Cycle life on this piece depends heavily on operating conditions. In a typical commercial repair shop running 6-10 lifts per day, the fj7497 sheave rotary should deliver five to eight years of service before showing measurable wear against the OEM inspection specification. In a high-volume tire or alignment shop running 20+ lifts per day per bay, expect service every three to five years. It is designed to be a serviceable component; when it does wear it wears within safe operating margins that trigger visible symptoms — drift, uneven wear, minor leakage — well before failure becomes a safety issue.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the fj7497 sheave rotary in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Return policy on the fj7497 sheave rotary follows our store-wide standard: all parts sales are final; exchanges only if the piece arrives defective. In the case of a defective delivery, ship the failed piece back to us at your cost, we verify the defect on receipt, and ship a replacement at ours. Wrong-item deliveries where we made the shipping error follow a different path — we reimburse the return shipping cost and cover freight on the correct part. Contact [email protected] with the order number to start either process.
Cross-reference & fitment
Fitment on the fj7497 sheave rotary is verified against the lift serial number when the order comes in. Even inside one manufacturer's catalog, a lift model built in one production year can carry subtle revisions from the same model built two or three years later. Sending us the lift serial number when you place the order — either in the order notes or in a follow-up email — lets us verify the piece against that specific serial's parts list. That five-minute step catches revision mismatches before shipping and prevents the delay of an incorrect delivery.
