The Challenger 36053 sheave is the direct replacement for the Challenger lift it came off of. Cross-referenced as ALS-7229-32, it is the genuine Challenger part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Challenger 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-7229-32 Brand: Challenger Type: Genuine OEM sheave Lift cables don't have a fixed lifespan; they have an hours-and-conditions lifespan. A busy shop that cycles a two-post twenty times a day wears cable and sheaves far faster than a home garage that lifts once a week. Grit, road salt dragged in on frames, and a rough sheave groove all speed it up. Most sets that see daily commercial use start showing broken strands somewhere in the five-to-ten year window. The cables, sheaves, and lock-release parts on a lift make up the tension path — the mechanical chain that ties both carriages together and keeps them rising at the same rate off a single cylinder. Steel cable runs over grooved sheaves, and small release cables trip the safety pawls so the lift can come down. Every one of these parts lives under constant load whenever a vehicle is in the air, which is exactly why they wear.

Anti-seize the pin on reassembly and install the new sheave with the bushing facing out. It's a short job that goes wrong fast if the retention hardware goes back in the wrong sequence, so the step-by-step is worth reading before you start.

Pull the model and serial off your lift's plate and open our Challenger parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it for you. Signs a cable or sheave is worn out For the lock-release cable, pull the handle and watch every pawl. They should all pop out of their ladders together. A pawl that lags, or a release cable that feels frayed or has lost tension, means the cable or its spring is failing. Check it for the same broken strands and corrosion as any other cable — it's thinner, so it goes faster. Parts commonly replaced at the same time Think in sets when you order tension parts: cables in pairs, sheaves with their pins, and the lock-release cable if it is due. It is far cheaper to do the whole wear group while the lift is open than to reopen it for the piece you skipped. Tell us your model and we will assemble the kit. Safety notes Safety here is simple and non-negotiable: a frayed cable or cracked sheave is an out-of-service condition, not a watch-and-see. Replace at the manufacturer's interval or at the first sign of broken wires, corrosion, or groove wear, and always equalize and cycle the lift empty before it carries a vehicle again. Before you order A quick prep before ordering saves a wrong box: confirm your model and serial, and measure the old cable if you can. The same lift can take different cable lengths across its run, so matching the actual part beats matching the brochure. We will verify fit for your serial before anything leaves. Confirm this is the right part before you order Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits. If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
