CASTROL MOLUB-ALLOY GM 969-320

Castrol Molub-Alloy™ GM 969/320 (previously called Molub-Alloy 969/320) Leak Resistant Gear Compound is specially formulated to help control leaks in gear cases when repairs cannot be immediately performed to eliminate the cause(s) of leakage. The synthetic thickener forms a mat- like matrix at the points of leakage to minimize the flow of oil. This product has a moderate thickening effect on the product, especially during storage or while the equipment is stationary. During the churning motion of gears and bearings, however, Castrol Molub-Alloy GM 969/320 exhibits the rapid flow and film-forming characteristics similar to a regular gear oil. Leakage from gear cases has traditionally been controlled by the substitution of a grease for the lubricating oil. This is unsatisfactory because greases can form "channels" and are poor at carrying heat away from the meshing gears and dissipating it from the gear case. In contrast, the synthetic thickener in Castrol Molub-Alloy GM 969/320 forms a gel and seals small openings in the gear case but otherwise acts like a standard gear oil in service. Application Castrol Molub-Alloy GM 969 Leak Resistant Gear Compound is formulated using a standard ISO base oil viscosity. Castrol Molub-Alloy GM 969 Leak Resistant Gear Compound was originally developed for service in heavy duty earthmoving equipment such as shovels and draglines. Surging stress and vibration on these machines inevitably produces some degree of leakage from gear cases. Excessive leakage at shaft seals is not uncommon on hoist, drag, propel and especially swing gear cases of large draglines and swing cases of shovels. Often the tramp oil will contaminate the heavy gear compounds necessary to lubricate the exposed open gear drives. The use of Castrol Molub-Alloy GM 969 Leak Resistant Gear Compound can be extended to control leaks in gearsets in industrial and marine applications. Advantages Performs as a heavy duty gear oil under normal operations. Will reduce or completely stop leakages until maintenance can be carried out.
