The Challenger TCS3-5-04-03-00 sheave is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — 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: TCS3-5-04-03-00
• Brand: Challenger
• Type: Genuine OEM sheave
• Fits: Q4P07

There is no cheaper insurance on a lift than fresh cable and sound sheaves. A cable set costs a fraction of a day's labor; a dropped vehicle costs the car, the downtime, and possibly somebody standing next to it. These parts hold real weight in the air. The moment a cable shows broken strands or a sheave won't turn true, the lift comes out of service until it's fixed — no exceptions worth making.

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.

Replacing your sheave

Swapping a sheave means getting the cable off it, driving out the pin without mushrooming it, and putting every spacer and clip back in the exact order it came apart. 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.

Find the right part for your lift

Landed here but not 100% sure it is your part? Grab the model and serial from the data plate and open our Challenger parts lookup for the visual breakdown — the manufacturer-style drawing with every item numbered so you can match yours exactly. Plate missing? our guide to finding your model number helps, and we identify lifts from photos every week if you would rather ask.

Signs a cable or sheave is worn out

On sheaves specifically, spin each one and feel for roughness or wobble on the pin. Sight down the groove for a step or a widened, polished channel where the cable has cut in. Check for cracks radiating from the bore and for a bushing that's walking out. A sheave that has grooved oversize will cord a brand-new cable within a season, so replace it while you're in there.

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.

Not sure this fits? 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.
