Mobilfluid 422

Mobilfluid 422 is an extra high performance, multipurpose tractor lubricant engineered to meet or exceed transmission and hydraulic fluid requirements. This product is formulated for the service top-up and refill of transmissions, final drives, and hydraulic systems of farm and industrial tractors and other mobile equipment and especially those with oil-immersed brake systems. This product is designed with special frictional characteristics to prevent squawk and chatter in wet brake systems and to deliver consistent braking performance. Mobilfluid 422 combines high performance base oils and an advanced additive package to deliver the varied lubricant performance properties required by these heavy-duty gear transmissions and heavily loaded final drives.

Features and Benefits

Heavy-duty agricultural and other mobile equipment load, speed, and temperatures have increased the requirements of power transmission fluids to deliver higher performance, increased productivity, and reduced operating costs. Friction control, wear protection, viscosity stability, rust and corrosion protection, and pumpability are features that must be properly balanced to provide extended clutch life, maximum braking efficiency, and reliable operation, even on uneven terrain and over a wide range of ambient temperatures. Mobilfluid 422 delivers outstanding performance in mobile equipment power transmissions, drive axles, clutches, Power Take-Offs (PTO) and hydraulic systems. The key benefits include:

Features	Advantages and Potential Benefits
Enhanced frictional properties especially for immersed disc brakes	Maximum braking efficiency with reduced squawk and brake chatter. Optimised clutch and PTO performance
Compatible with clutch materials and elastomers	Longer clutch life, reduced leakage, and reliable response
High viscosity index with improved shear stability	All-season performance with consistent hydraulic operation
Excellent protection against rust, corrosion, and yellow metal etching	Protects equipment in wet or humid environments and prevents premature wear
Excellent low temperature properties	Insures prompt fluid circulation and responsive control under all conditions even in cold weather applications
Strong anti-wear and extreme pressure properties	Reduces wear, extends equipment life, and reduces maintenance costs
High thermal and oxidation stability	Reduces deposits and sludge to prevent clogged oil ways and impaired hydraulic actuation
Good filterability	Keeps systems clean and operating smoothly

Applications

• Heavy-duty transmissions, differentials, final drives, hydraulic systems, power steering systems, wet brakes, PTOs and hydrostatic drives used in agricultural, contractor, and industrial applications
• Recommended for top-up and refill of systems Particularly suited for sintered bronze oil-immersed disc brakes
• Do not use in passenger car automatic transmissions
• May be used in applications requiring API GL-4 or SAE 80 Grade lubricants in all gear applications except hypoid gear designs
