John Deere GL-5 Gear Lubricant
GL-5 is the preferred oil in John Deere compartments when gear oils are recommended. API GL-5 is for service similar to GL-4, but for more severe conditions. It applies to conditions encountered in hypoid gears. Other equipment operated under high-speed, shock-load; high-speed, low-torque; and low-speed, high-torque conditions may specify API GL-5.
John Deere GL-5 Gear Lubricant Applications
Today’s high-speed, high-torque power trains use relatively small gears. The result is high sliding speeds and contact loads between mating parts. This makes lubrication more critical.
In some applications and gear designs, the gear oil must have special anti-wear agents.
John Deere GL-5 Gear Lubricant Features and Benefits
One of the most important gear lubricant performance characteristics is load carrying capacity.
Some gears are operated under such loads and speeds where the very low load-carrying capacity of untreated oil is adequate.
However, most gears require lubricants of greater load-carrying capacity, which is provided through the use of additives.
Gear lubricants compounded to achieve increased load-carrying capacity are referred to as “extreme-pressure” (EP) lubricants.
However, when this term is applied to a gear lubricant, it means only that the load-carrying capacity of the lubricant is greater than that of untreated oil, with no distinction as to how much greater it may be. Therefore, to differentiate among EP lubricants of various load-carrying capacities, it is necessary to classify them further.
The Component Manufacturers and ASTM have developed tests and the American Petroleum Institute (API) has assigned designations to aid in determining lubricant application.
John Deere GL-5 Gear Lubricant Specifications
Designed for gears, particularly hypoid which operate under conditions of high-speed, low-torque and low-speed, high-torque
Can be used in any application requiring API, GL-5; SAE 80, 90, 80W-90, or 85W-140 gear lubricants.
John Deere GL-5 Gear Lubricant Mixing Lubricants
As a general practice, the mixing of lubricants should be avoided.
Mixing gear lubricants with even small amounts of other types of lubricants can result in antagonistic reactions between the additive chemicals in the mixture. Such reactions may result in a significant loss of gear protection.
Always follow your equipment manufacturers’ recommendations for gear lubricants
