When 309-5711 reaches the buying desk, photos matter more than a long story. Check the removed CAT unit before treating this page as a final match.
Useful photos show the front screen layout, rear connector, label sticker, and mounting tabs. On excavators, loaders, generator sets, marine engines, and road machines, those small details often prevent a wrong shipment.
A cab display can look close while the rear plug or screen version is different. Send the part number, machine model, quantity, and destination with the enquiry. Short evidence helps the sales team compare the unit without turning the request into a repair discussion.
