Case Wheel Loader 1021F 1121F Tier 2 Service Manual
INTRODUCTION:
- Coolant solution: Put only ethylene-glycol coolant solution in the cooling system. Use good quality ethylene-glycol that has a high boiling point with no additives to prevent leakage. Do not use non-approved anti-rust additives. Anti-rust additives and ethylene-glycol can mix and work against each other, reducing anti-corrosion protection, forming deposits in the cooling system, and causing damage to the cooling system and radiator. Contact your dealer who can supply you with the suitable coolant solution.
- Anti-freeze/Anti-corrosion: Use anti-freeze in all seasons to protect the cooling system from corrosion and risk of freezing. For areas where the ambient temperature is over -36 °C (-32.8 °F) use a blend of 50% ethylene-glycol based anti-freeze. For areas where the temperature is below -36 °C (-32.8 °F)- it is advisable to use a blend of 40% water and 60% anti-freeze.
- Fuel:Use diesel fuel suitable for the ambient temperature conditions (ASTM-D-975). Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard. Use grade No. 2 fuel. The use of other types of fuel can result in a loss of power of the engine and may cause high fuel consumption. In very low ambient temperatures, use a mixture of fuels No. 1 and No. 2 as necessary. Consult your fuel supplier for appropriate fuel supply. If the temperature falls below the fuel cloud point (point at which wax begins to form) the wax crystals will cause power loss or will prevent the engine from starting. In cold weather, fill the fuel tank at the end of the day’s work in order to prevent the formation of condensation.
- Fuel storage: Prolonged storage of fuel can lead to the accumulation of impurities and condensation in the fuel. Engine trouble can often be traced to the presence of water in the fuel. The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible. Drain off water and impurities regularly.
- Hydraulic fluid: Case Akcela Hy-Tran Ultra hydraulic fluid is specifically designed for high pressure applications and for Case hydraulic systems. Your Case Dealer can provide hydraulic fluid to fulfill different climate/temperature conditions. Refer to the charts at the beginning of this section.
- Transmission component oil: Extreme pressure oil should be used for enclosed transmission components. Choose an oil that is manufactured for your climate/temperature conditions such as Case Nexplore or CNH F200A. See charts at the beginning of this section.
- Grease:The type of grease to use depends on ambient temperature such as: Case Akcela Molydisulfide Grease
- Environment:Before you service this machine and dispose of oil, fluids, and lubricants, obey environmental regulations. Do not drain oil or fluids on to the ground or into containers that leak. Check with your local environmental, recycling center or your dealer for correct disposal information.
- Engine oil:Case Akcela engine oil is recommended for your engine. This oil insures correct lubrication of your engine in all working conditions. See charts at the beginning of this section to choose the correct oil for climate/temperatures. If Case Akcela engine oil cannot be obtained, use only oil of the API SERVICE CI-4 category.
