Mobiltrans HD 50 

Mobiltrans™ HD 50

Mobiltrans HD 50, is an extra high performance, heavy duty transmission and drive-train lubricants engineered to meet or exceed the requirements of the rigorous Caterpillar TO-4 specification. This product line is uniquely designed to optimise the performance of powershift transmissions, gearboxes, and final drives. In hydraulic applications, it provides maximum protection even in high pressure systems

This technology combines selected base oils and an advanced additive system to deliver the precise performance parameters needed to maximise the productivity of construction, quarrying, and mining equipment operating in severe conditions. This product offers a clear performance advantage over the use of mixed fleet engine oils and previously used lubricants meeting Caterpillar TO-2.

Today’s technology has vastly improved the performance capabilities of heavy duty earth moving equipment in terms of load, speed, control, precision, and reliability through innovative power train designs. These designs have increased the requirements of power-train fluids to deliver higher level of performance, productivity and efficiency. Friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and pumpability are features that must be optimally balanced to provide extended clutch life, slippage control, maximum drawbar loading, and high load operation even on an inclined slope at extreme temperatures. Mobiltrans HD 50 delivers exceptional performance in today’s power train transmissions, drive trains, and hydraulic systems. The key benefits include:

Features

Advantages and Potential Benefits

Balanced static and dynamic friction coefficients

Optimised clutch-friction retention and slippage control
Significantly improved clutch life compared to the best API CD/TO-2 engine oils

Compatible with modern clutch materials and elastomers

Longer clutch life and higher performance

Increased levels of anti-wear and load carrying capability

Reduced gear wear and extended life in transmissions, gearboxes, and final drives
Greater productivity from reduced downtime

Excellent foam control protection

Top performance in wet brakes; excellent control of brake chatter

Excellent thermal and oxidation stability

Outstanding hydraulic oil stability and protection against high-pressure pump wear

Lower viscosities offer very good low temperature pumpability

Reduced time from start-up to production

Recommended by ExxonMobil for use in:

  • Heavy duty transmissions, gear boxes, final drives, and hydraulic systems used in off-highway applications
  • Off-highway industries including: mining, construction, quarrying, and agriculture
  • Manual, powershift, and automatic transmissions where Allison C-4 fluids (SAE 10W and 30 grades) are called for including Twin Disc and transmissions calling for Type F fluids
  • Most mobile equipment hydraulic applications
