Valvolube 80W90 gear oil for Terex RT670

This gear lubricant, identified by part number 80W9OVALV, is designed for use in heavy machinery transmissions and differential assemblies. It is specifically intended for the Terex RT670 rough-terrain crane, ensuring that internal gear components receive consistent lubrication during operation. The 19-liter volume is suitable for standard maintenance intervals and system refills in this crane model.

The 80W90 viscosity grade maintains fluid properties across a range of operating temperatures, which is necessary for the protection of gear sets under load. This lubricant is formulated for use in systems containing hypoid and helical gears, helping to manage friction between moving parts within the transmission and differential housings. By maintaining the correct oil level and condition, operators support the mechanical integrity of the drivetrain components.

Gear oils serve as the primary medium for heat dissipation and friction reduction in heavy machinery gearboxes. They create a protective film between gear teeth and bearings, which is necessary to manage the pressures encountered during lifting and travel operations. Regular fluid maintenance is standard practice to ensure that transmission systems remain clean and operate within specified parameters.
