D-A TorGuard FD™ are performance engineered lubricants designed specifically for final drive axle oil (FDAO) type applications that require the Caterpillar FD-1 specification.
D-A TorGuard FD™ when used under normal operating conditions, can have drain intervals up to 3,000 operating hours. Special additives are added to control foaming tendencies while deterring pitting and scuffing within gears and bearings. In addition, the robust additive package controls rust and exhibits very good oxidation stability to combat contact fatigue within the drive system.
D-A TorGuard FD™ is not recommended for final drive components that contain frictional materials such as wet disk systems.
