( 1 ) The machine is delivered from the factory with the designated fluids.
( 2 ) Do not use API GL-5 or API GL-4 Gear Oils for the Vibratory support, the Final Drive Planetary (Drum), or the Eccentric Weight Housing. 4C-6767 (185-4759) Synthetic Oil is a premium PAO (Polyalpaolefin) synthetic gear and bearing lubricant with no viscosity improvers. This lubricant has an ISO viscosity grade of 220, and a minimum viscosity index of 152. Commercial oil selected for this application should have a full synthetic base stock with no viscosity improvers, an ISO viscosity grade of 220, and a minimum viscosity index of 150.Commercial Oils
If Caterpillar oils cannot be used, the following commercial classifications can be used in hydraulic systems and in hydrostatic transmission systems.
Engine oils that meet the Caterpillar ECF-1 specification and have a minimum zinc additive of 0.09 percent (900 ppm)
API CG-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
API CF engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
TO-4 Oils, or Oils that meet Caterpillar's TO-4 Oil specification, that have a minimum zinc additive of 0.09 percent (900 ppm)Note: Industrial hydraulic oils are not recommended for use in Caterpillar machine hydraulic systems.
