MORRIS Lubricants has updated the formula for its proven Terrain LS 80W-90 off-highway gear oil, to satisfy the demands of limited slip differentials (LSDs) as well as wet (oil-immersed) brake systems in one universal product.
Part of the proven Morris Lubricants’ Terrain range of oils and lubricants, designed specifically for the rigours of off-highway vehicle and equipment operation, the new Terrain LS 80W-90 is a truly innovative 2-in-1 universal gear oil – enabling customers to reduce oil stock levels considerably, save money and keep machinery running at peak performance.
Traditional oil formulations are designed to either protect components against high shock loads or to ensure positive engagement in wet brake systems. The new Terrain LS 80W-90 does both and its formula combines high levels of extreme pressure protection and optimised frictional performance in a single gear oil – making it a true 2-in-1 universal gear oil for the off-highway sector.
Purpose-built for high differential loadings
Morris Lubricants’ new Terrain LS 80W-90 is designed to work in various operating conditions. In particular, where LSDs need to provide balanced power distribution to the wheels in environments where traction may be an issue, such as in deep mud or on loose aggregate.
As the drive system detects traction issues, the axles are locked, equalising the power and allowing the vehicle to manoeuvre. This action creates a high shock load and, gear oils for LSDs are formulated to offer high levels of component protection under these conditions.
This is where the benefits of the Terrain LS 80W-90 are seen clearly. The product is formulated to very high standards and exceeds API GL-5 gear oil specifications for arduous environments, offering superior extreme pressure protection, under these high shock loads.
Protection for wet brake systems
The second important performance attribute of the new Terrain LS 80W-90 is its ability to cope with the exacting frictional demands of wet brake systems. Due to the hard off-highway operating environments, this type of brake system is essential to prevent abrasive contamination that would have a severe impact on the longevity and effectiveness of components.
Terrain LS 80W-90 is formulated using friction modifier chemistry to ensure positive engagement of clutch pack materials. This enables the system to stop the vehicle smoothly and safely. ‘Squawk and chatter’, which is associate with the stick/slip of clutch materials resulting in noise and vibration can also be eliminated using Terrain LS 80W-90.
Cost effective inventory rationalisation
As a 2-in-1 product, Terrain LS 80W-90 can also offer inventory rationalisation, avoid stocking more products than are needed and therefore reduce costs. It can be used in standard axles and differentials where a basic API GL5 80W-90 gear oil is required.
Adrian Hill, Technology Manager at Morris Lubricants, explains, “In the off-highway sector, the gear oil must fulfil a number of demanding jobs, and traditionally, chemistry in the oils used for LSDs and friction modification for wet brakes don’t complement each other.
“Our new Terrain LS 80LW-90 is capable of these two very different jobs, reducing downtime and providing operators with peace of mind. With superior shock loading protection and modified friction performance, the Terrain LS 80W-90 can be used throughout the drive axle without compromise.
“In selecting this 2-in-1 universal gear oil, operators can not only reduce stock levels and costs, but also improve component longevity, helping to minimise downtime on site.”
The new Morris Lubricants’ Terrain LS 80LW-90 off highway gear oil is available now in 25 litre, 205 litre and bulk ICB containers.
