Product Description

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
