Mobil Delvac Modern Final Drive 50
Extra High Performance Drivetrain Lubricants
Mobil Delvac Modern Final Drive Series has replaced the Mobilube XFD Series. There are no formulation changes thereby ensuring no impact on product compatibility or handling. Furthermore, there are no comingle restrictions on mixing products with old and new names. Technical claims and product performance remains unchanged.
Mobil Delvac Modern Final Drive 50 and 60 are extra high performance drivetrain lubricants engineered specifically to provide optimum component life when used as recommended in Caterpillar final drives and axles. They are formulated from advanced base oils and the latest additive technology to protect bearings and gears from premature failure due to fatigue. These lubricants deliver excellent performance in heavy-duty commercial axles and final drives where extreme pressures and shock loading are expected. They provide exceptional chemical and thermal stability at elevated bulk oil temperatures generated under heavy loads and/or high ambient temperatures.
Mobil Delvac Modern Final Drive Series have been extensively field tested in Caterpillar off-highway heavy trucks and bulldozers over a wide range of ambient temperatures and operating in severe conditions with a recommended drain interval up to 4,000 hours for off-highway haulers.
Features and Benefits
Demands for higher productivity, more severe operating conditions, andl arger capacity equipment put severe stress on axles and final drive components. In severe applications, TO-4 lubricants may be limited in terms of wear protection in heavily loaded final drives due to their need to also serve the frictional requirements of clutches in heavy-duty transmissions. For optimum durability and performance, Mobil Delvac Modern Final Drive gear lubricants can be relied on to maintain productivity and minimize maintenance costs between scheduled service intervals in extreme applications. The key benefits include:
