Transmission oils HD10W, 30, 50, and 60 are high-performance heavy-duty transmission and transmission system lubricants specially formulated to meet the strict standards of Caterpillar TO-4. This series of products is specially formulated to enable excellent performance of power shift transmissions, gearboxes, and rear axles. In hydraulic applications, even in high-pressure systems, they can still play a protective role.

The technology used in this series of products combines selected base oils and advanced additive formulations to achieve precise performance indicators. These indicators are key factors in improving the productivity of construction, quarrying, mining and other equipment under harsh operating conditions. The performance of these products is significantly superior to the engine oils used in hybrid fleets, as well as the lubricants previously used that meet Caterpillar TO-2 specifications.

Features and Advantages

Through innovative transmission system design, modern technology has improved the performance of heavy-duty bulldozers in terms of load, speed, accuracy, and reliability. These design changes increase the requirements for transmission system lubricants to achieve higher performance, improve productivity, and efficiency. The characteristics of friction control, wear protection, thermal stability, mechanical shear stability, rust and corrosion prevention, and pumping performance must be well balanced in order to extend clutch life, control slip, achieve high traction rod loads, and operate under high loads even under harsh temperature conditions. The main advantages are as follows:
