Product Information:
TERRAIN CT10, CT30, CT50, CT60
OFF-HIGHWAY TRANSMISSION / HYDRAULIC FLUIDS
|
Description
The Terrain CT range is formulated with high quality mineral oils and additives designed to provide the correct frictional characteristics required by Caterpillar in transmission and hydraulic systems. The additive system also gives this oil improved temperature performance, superior resistance to oxidation, rust, corrosion and improved anti-foam properties. In addition these grades have excellent extreme pressure (EP) and anti-wear characteristics ensuring maximum frictional material life in powershift transmissions.
Terrain CT grades also have outstanding wet brake performance, eliminating “squawk and chatter” and prolonging component life.
Applications
The Terrain CT grades are designed for use in a wide variety of Caterpillar construction and material handling equipment. Applications include: powershift transmissions, direct drive transmissions, winches, final drives for track-type tractors (pipelayers, skidders, loaders, excavators, etc.) and wheeled tractors (loaders, compactors, graders, etc.) and certain hydraulic systems.
These grades may also be used in Allison and ZF powershift transmissions, manual transmissions and torque converters, where an oil of this type and specification is required.
