Mobil Xtra YMP WT
Mobil Xtra YMP WT is a top treat solution specifically developed for wind turbine gearboxes using Mobilgear SHC XMP 320. The product is designed to help extend the service life of the existing gear oil charge when maintenance schedules go beyond the standard warranty period. It is formulated to protect yellow metal components from corrosion while maintaining reliable gearbox performance until the planned oil change.
One of the key advantages of Mobil Xtra YMP WT is its ability to extend oil life. By adding a small amount of the product to the existing gear oil, operators can maintain lubrication performance and delay full oil changes. This helps avoid challenging oil change operations while protecting gearbox components. The additive supports continued protection of equipment and reduces maintenance disruption.
Mobil Xtra YMP WT also provides protection for yellow metal components. The formulation is specifically designed to help minimise corrosion, which can occur during extended service intervals. This contributes to improved equipment reliability and reduced wear within wind turbine gearboxes. The product helps maintain performance when used oil analysis indicates increased copper levels.
Another important benefit is its ease of application. Mobil Xtra YMP WT is typically added at approximately 1% of the total gear oil volume. The additive is poured slowly into the gearbox while ensuring adequate oil circulation. This simple application method helps minimise downtime and simplifies maintenance planning.
Mobil Xtra YMP WT is recommended for use in wind turbine gearboxes containing Mobilgear SHC XMP 320 where oil life extension is required. The product supports improved reliability, reduced unplanned shutdowns and extended maintenance intervals. It is particularly useful where full oil change procedures are difficult or impractical.
