OY1104 0.5Ton pneumatic Transmission Jack

The OY1104 is a 0.5‑ton pneumatic transmission jack, designed for automotive workshops and transmission service centers seeking to combine moderate lifting capacity with the speed and ease of air‑powered operation. With a maximum rating of 0.5 tons, this jack is ideal for passenger car transmissions, transaxles, and transfer cases. The OY1104 connects to a standard shop air supply and utilizes a pneumatic‑over‑hydraulic cylinder to raise the load with the simple push of a button or turn of a valve.The pneumatic system also delivers a consistent lifting speed regardless of load, reducing the risk of sudden jerks or uneven movement.
The pneumatic control system is simple and intuitive. Raising is instantaneous – press the button and the saddle rises smoothly. Lowering is controlled by a separate precision release valve that allows gradual descent, essential for seating the transmission onto its mounts without binding. A built‑in pressure regulator prevents over‑pressurization, and an overload relief valve ensures the 0.5‑ton rating is never exceeded. The durable powder‑coated finish resists oil, grease, and workshop wear. Standard accessories include adjustable support arms, a safety chain, a pneumatic hose with quick‑connect fittings, and an operation manual.
