  • Industry-leading friction performance: For precise, smooth and confident control.

Superior wear protection and load carrying capability

Load Carrying Capacity

High-performance machines are expected to do big things. This inevitably and unavoidably equates to higher maintenance costs. Maintenance is typically one-third of the total cost of ownership of off-highway machinery (alongside fuel and depreciation costs), so anything that reduces this burden is welcome.

Incredibly high forces are channelled through the final drives, where wear to the spur gears can be a big problem. This is the main reason why field engineers seek higher performance off-highway lubricants. The higher performance of HiTEC® 8888z additive minimizes wear, prolongs gear life and provides extra protection against heavy loading.

This leads to smaller maintenance bills, extended machine life, reduced downtime and improved performance in fleet operations. And all at a competitive treat rate.

Outstanding yellow metal protection

The advanced yellow metal protection provided by HiTEC® 8888z additive greatly improves corrosion performance, providing protection for copper even in the most severe operating environments.

Yellow metals can be found in hydraulic systems, thrust washers, sintered bronze friction plates and oil cooling systems. Higher performance protects these crucial components to maintain optimum machine operating performance for longer, while also extending component life.

Industry-leading friction performance

The wear to friction components, such as clutches and brakes, is a major cause of unexpected onsite downtime and lost productivity. HiTEC® 8888z is a higher performance off-highway lubricant additive, specially formulated to provide optimum friction control and reduce unplanned maintenance. And the result is a vast reduction of wear on the clutch plates.

Since clutch plate wear is the biggest cause of transmission failure, HiTEC® 8888z additive adds significant value by considerably reducing machinery downtime. This optimized friction performance ensures that these big and powerful machines are altogether smoother, more precise and more assured for the operators. Operator confidence can enhance productivity and output. In this way, the higher performance of HiTEC® 8888z adds yet further value.

Wider Fleet coverage

In a harsh off-highway environment, only the toughest machinery survives. And as machinery manufactures compete hard, each offering different strengths based on different operational needs, operators are increasingly more careful with their choice of machinery.

The result, more often than not, are fleets of different construction machines from different manufacturers. Until now, this has created a logistical headache for the maintenance team.

HiTEC® 8888z offers wider fleet coverage including:

  • Unique set of OEM approvals: Latest coverage for modern machinery

  • Broadest fleet coverage: Ideal for a larger number of fleets and work sites

  • Simplified logistics and handling: More time to do the real work

Afton estimates that, worldwide, over 80% of fleets are now mixed.

Broad fleet coverage has become a common feature amongst most working sites today, as everyone seeks the best options to become more and more effective.

Whether at mines, construction sites, amongst plant hire companies or contractors, most fleets use a patchwork of different manufacturers’ machinery, each providing a unique benefit within the fleet operation.

By offering a more universal off-highway lubricant, with the widest fleet coverage, HiTEC® 8888z transmission and drivetrain additive is something you simply cannot ignore.

    The means of transferring power to the terrain. Reduction gear sets reduce the speed and increase torque. Power transfers to the wheels (incorporating wheel brakes) then to the ground.

    hitec® 8888z offers superior load carrying for reducing wear, along with excellent bearing protection.

  2. Axle and Differential
    Fill volume 500L
    The rear axle incorporates the differential, which as well as providing a gear reduction, allows the wheels to rotate at different speeds (when cornering or on rough ground).

    hitec® 8888z transmission and drivetrain additive offers strong extreme pressure performance and reduced wear.

  3. Powershift Transmission with Lock-Up Torque Converter
    Fill volume 620L
    A lock-up torque converter is a fluid coupling linking the engine to the transmission that can be locked for maximum efficiency. The powershift transmission matches engine and ground speed via a choice of different gear ratios.

Why higher and wider?

'Higher and Wider' describes the unique attributes of HiTEC® 8888z that allow it to offer Higher Performance and Wider Fleet Coverage.

What are wet brakes?

Oil-immersed brakes are also known as wet brakes, and are widely used in off-highway heavy machinery, such those used for construction and mining. The vehicle’s braking system is enclosed to prevent mud and dirt from getting in. To keep the brakes cool and extend life, they are immersed in lubricant. This lubricant therefore needs to transfer the braking forces, so its friction properties become critical to smooth but efficient braking. The friction properties of HiTEC® 8888z have been carefully optimized to provide Higher Performance in appropriate braking systems.

Why is friction important?

Friction is a crucial property in many parts of off-highway machinery. Transmission clutches, wet brakes, lock-up torque converter clutches and limited slip differentials all rely on the right friction profiles. The lubricant is a crucial part of the friction system in all of these components. The friction design of HiTEC® 8888z lubricant additive provides Higher Performance. Higher friction performance can help improve operator comfort, increase productivity, deliver longer parts life, decrease total cost of ownership and reduce downtime.

How can a lubricant provide higher machine performance?

An off-highway universal lubricant, such as that formulated with HiTEC® 8888z additive, will see a massive range of parts throughout the machine. The lubricant has a crucial role in transferring power and protecting parts. The right lubricant can make a big difference to the cost and productivity of a machine, work site or fleet operation.

How can a higher performance help my cutomers?

Higher Performance can mean more precise, smooth and confident control, which aids fleet productivity. Maintaining parts as they are meant to be for longer helps reduce direct costs and crucially helps reduce machinery downtime due to unplanned maintenance. Together this reduces total cost of ownership.

How do I know the higher performance will last?

Afton Chemical has undertaken extensive testing with HiTEC® 8888z additive showing that not only is the performance higher when first tested, but also as it ages. When compared to commercially available off-highway lubricants, those using HiTEC® 8888z transmission and drivetrain additive showed Higher Performance in extended durability testing, retaining torque capacity while protecting the plates from wear. In other testing, candidates were artificially aged then tested – HiTEC®
