New Organic Acid Engine Coolant Technology OAT coolant is required for new CASE Tier 4b engines with ≥ 56 kW emissions. Use OAT coolant to avoid the risk of serious engine damage through overheating. About OAT Coolant ACTIFULL™ OT EXTENDED-LIFE COOLANT is CASE's OAT coolant Supplemental Coolant Additives (SCA) are not necessary with OAT coolant that meets MAT 3624 It's yellow in color When should you use OAT? All new CASE Tier 4b vehicles with Flat Power Train (FPT) engines that are in the ≥ 56 kW emissions category require OAT coolant Look for one of the ACTIFULL™ OT decals shown before you add or change the coolant OAT Coolant Part Numbers Case Akcela ACTIFULL OT® extended life coolant concentrate 1 GAL - 73341735 55 GAL - 73341736 Case Akcela ACTIFULL OT® extended life coolant premix 1 GAL - 73341738 2.5 GAL - 73341739 Best Practices for OAT Coolant Never Mix OAT with Regular Coolant Mixing coolants can cause a loss of stability in the corrosion inhibitor, cavitation erosion, and gelling damage. This type of damage is not covered by your warranty, and repairs can cost thousands of dollars. Adding as little as 10% of regular coolant in an OAT system is enough to cause damage to your machine. Look for the OAT decal before adding or changing coolant to ensure you don't mix coolants and cause gelling inadvertently. Selecting Coolants Do not risk using OAT coolants from other manufacturers, unless they specifically meet CASE's MAT3624 material requirements. Use the ATSM number, not the coolant color, for reference when selecting your coolant. Mixing OAT with Water Mix half OAT and half water ratio, which will protect cooling systems to -35° F (-37° C). Only use de-ionized water with OAT coolant. Tap, hard, softened or sea water will reduce the coolant life and can cause deposits to form, creating hot spots and cavitational corrosion. Avoid Machine Damage Do not use anti corrosive additives in an OAT cooling system. Although these additives are commonly used in ethylene glycol fluids, they can cause premature wear in your machine. Only use machines with chemical resistant hosing. OAT coolant will react with PVC, rubber and Viton seals, creating leaks over time. Note: Use of OAT is not recommended for older machines. If you choose to run OAT in an older application, the cooling system must be flushed. The nitrate level must not be higher than 20 ppm. Oil Requirements Engine oil requirements may have changed, too, due to Tier IV emissions technologies. Low-ash CJ-4 oil is required for machines with DPF Non-DPF machines can run either CI-4 or low-ash CJ-4 oil There is no industry standard for CJ-4 oil additives. Don't risk premature engine wear by using oil that is not formulated for your machine.
When to refill the tank On Case equipment, there is a DEF gauge, just like the fuel gauge. It shows the fluid level and indicates when it’s time to refill. When fluid level becomes low in the DEF tank, a series of warnings will alert the operator after DEF reaches less than 10% of capacity. If the DEF tank contains less than 5% of its capacity, the equipment engine power will de-rate. Enough power will be available, however, to travel a short distance, so you can add DEF to the tank. The DEF tank needs to be filled once every 3 to 4 times that you refuel with diesel fuel in Case machines. The frequency will vary with operating conditions. How to fill the tank The opening of the DEF tank is sized to accept only a DEF fill nozzle. This constraint ensures that only DEF can be pumped into the DEF tank. A standard nozzle for diesel fuel will not fit into the DEF tank opening. DEF tanks will hold between 15 and 50 gallons, depending on the equipment size and horsepower. About DEF Composition Diesel Exhaust Fluid (DEF) is non-toxic and is made up of purified water and urea. It is stable and colorless. DEF is similar to baking soda in its alkalinity (pH). It is not a fuel but is used to reduce the level of nitrogen oxides in the emissions to meet emissions control standards. Purpose In the Selective Catalytic Reduction (SCR) system, DEF is injected into the exhaust. It converts the NOx into nitrogen gas and water vapor, which are harmless components of air. Storing Keep DEF out of direct sunlight. The ideal temperature range for storing DEF is 32° F to 86° F, and its average shelf life is 3 years. DEF begins freezing at 32° F. The DEF tank on the vehicle has a heater that will thaw the DEF quickly. Freezing and thawing does not change its effectiveness. Because of its alkalinity, it can cause oxidization in the same way that oxygen rusts raw steel, so it needs to be stored in plastic or stainless steel containers. Burris Equipment also offers a complete line of DEF transfer pumps and meters, including on-site bulk storage equipment options. All Case DEF meets ISO Standards for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These standards are the highest for quality and safety and ensure optimum SCR system performance.
A few simple maintenance routines can extend the life of your skid steer tires dramatically. Clean your Tires Hose down your tires routinely so they are easy to inspect. Look for bubbles, bumps, cracks, and anything that might be lodged in the rubber. Check the Tread A quick visual inspection will also reveal any uneven wear. On skid steers, one set of tires may wear faster (the front or rear), depending on how they are operated. Rotate the tires as soon as you notice any uneven wear, which will extend the life of all four tires. Operate with All Four Tires Engaged There is less wear on the tires and the machine when the skid steer is operated with all four tires engaged on the ground. When the bucket is too far beneath a load, the front tires may lift slightly off the ground, placing stress on the back tires. Keep the Tires on the Ground Skid steer tires are designed for operation on ground, not on road surfaces. Consequently, the tires will wear out faster when they are driven on roads rather than on the ground. Watch for Debris Skid steers are operating in areas that are often full of debris. Drive carefully and avoid litter. Pneumatic tires can go flat, and foam-filled tires can leak if punctured. Protect the Rims Avoid popping off retaining rims, which can occur by catching the rim on an object. It’s inexpensive to replace a rim, but the downtime associated with unnecessary maintenance can be quite expensive. Look for tires with rim protectors built into the design. Monitor the Pressure With pneumatic tires, if the tire pressure is too low, you will waste fuel, and if it’s too high, you increase the chance of flats. In either case, uneven wear can result. Keep a reliable tire gauge handy and check the pressure every day or once a week, depending on how often you are operating the skid steer. Check your owner’s manual for the acceptable tire pressure range. Store Properly Constant exposure to sunlight can cause tires to expand and crack. Store tires in a cool, dry place. Buy Consistent Brands Avoid installing different brands or models of tires on the same machine. Each brand has its own distinct design and combining brands can cause uneven wear on both your tires and your skid steer.
