Divinol Getriebe- Hydrauliköl TO-4 10W is a gear and power-transmission oil for construction machines, developed for powershift transmissions, final drives, hydrostatic drives, torque converters, wet clutches and wet brakes as well as hydraulic systems in which special TO-4-type oils are required. The SAE 10W grade is typically specified for hydraulic circuits and transmissions operating in cooler conditions. The oil provides optimal friction characteristics, also at low temperatures, together with high anti-wear protection even under heavy conditions. It gives professional protection to transmission gears under impact load and perfect corrosion protection, making it a very good power-transmission oil for demanding off-highway duty. Divinol Getriebe- Hydrauliköl TO-4 10W meets API GL-4 and the manufacturer states performance in line with Caterpillar TO-4, TO-4M and TO-2, Allison C-4, Dana, Eaton/Sperry M2905S & I-280S, Komatsu Micro Clutch, Komatsu KES 07.868.1, JCB Standard 4000/2500 and ZF TE-ML 03C/07D, all of which are also listed by Divinol Romania.
