Lubrication Oil Engine Oil Refer table A for oil specifications. Other oils can be used if they meet minimum requirement of : API service classification CF4 + Mb228.1 CCMC D-4 / G-4 / PD-2 MIL - L - 2104E. Multi-Viscosity Diesel Engine oils are preferred. Selecting the Viscosity of Engine Oil (EO) During cold weather the selection of oil should be based on the coldest anticipated operating temperature to make starting easier. During hot weather, selection should be based on the highest anticipated operating temperature. When the prevailing temperature changes substantially, even though the regular intervals of lubricant change have not been reached, the lubricant must be changed. Refer Oil Specifications Chart for oil specifications at different range of ambient temperatures. Following oils of SAE grade 15W40 are recommended for temperature range of -150C to 500C. 1. Citgo - Citgard 500 15W40. 2. Exxon - XD3 Extra 15W40. 3. Chevron - Delo 400 15W40. 4. Mobil - Devlac 1300 15W40. 5. Shell - Rotella T 15W40. 6. Texaco - Ursa Super Plus 15W40. Ambient temperature conditions in other range warrants other SAE grade of oil as per illustration. Transmission, Hydraulics and Steering Oil (GL) Use mild EP type gear lubricant. They should meet API GL4 performance category with suitable additives meant for paper based brake liner. Use viscosity based on the expected air temperature range during the period between oil changes. Please refer Oil Specifications Chart for oil specifications at different range of ambient temperatures. Following oils are recommended, 1. GULF Universal Tractor Transmission Fluid. 2. Exxon Torque fluid 56. 3. Shell Donax TD. 4. Mobil fluid 424. 5. Tractelf BF 12 6. Tractelf C4 - 1000 7. Hydro Clear Power Train Fluid. Other brands may be used if they meet all the specifications and performance levels of the above. 74
Note : If diesel fuel with sulphur content greater than 0.05% is used, reduce the service interval by 50%.
Note : It is not necessary to change the lubricant when the temperature enters into a different range during a working day, unless difficulty in starting is experienced. Change oil if the tractor is not used for 6 months. PRECAUTIONS : After changing the oil, operate the engine at low speed without load, for at least 5 minutes. This will allow the oil to work into the bearings and onto the cylinder walls. * Factory filled oil is 15W40 and may change in future.
Note : Universal Tractor Transmission Oil. Oil shall meet API GL4 performance category. Factory filled oil is Tractelf MM H3 and is subject to change in future. 25 Series 2WD, Model - 3825 / 4025 / 4525
