SEBU8726-03 61 Operation Section Cold Weather Operation Cold Weather Operation Check all rubber parts (hoses, fan drive belts,) weekly. i06024580 Cold Weather Operation Check all electrical wiring and connections for any fraying or damaged insulation. Keep all batteries fully charged and warm. Perkins Diesel Engines can operate effectively in cold weather. During cold weather, the starting and the operation of the diesel engine is dependent on the following items: Fill the fuel tank at the end of each shift. Check the air cleaners and the air intake daily. Check the air intake more often when you operate in snow. The type of fuel that is used Ensure that the glow plugs are in working order.
Refer to Troubleshooting, “Glow Plug Starting Aid- Test”. The viscosity of the engine oil The operation of the glow plugs Optional Cold starting aid Personal injury or property damage can result from alcohol or starting fluids. Battery condition This section will cover the following information: Alcohol or starting fluids are highly flammable and toxic and if improperly stored could result in injury or property damage. Potential problems that are caused by cold- weather operation Suggest steps which can be taken in order to minimize starting problems and operating problems when the ambient air temperature is between 0° to−40 °C (32° to 40 °F).
Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury. The operation and maintenance of an engine in freezing temperatures is complex . This complexity is because of the following conditions: For jump starting with cables in cold weather, refer to the Operation and Maintenance Manual, “Starting with Jump Start Cables.” for instructions. Weather conditions Engine applications Viscosity of the Engine Lubrication Oil Recommendations from your Perkins dealer or your Perkins distributor are based on past proven practices. The information that is contained in this section provides guidelines for cold-weather operation.
Correct engine oil viscosity is essential. Oil viscosity affects the amount of torque that is needed to crank the engine. Refer to this Operation and Maintenance Manual, “Fluid Recommendations” for the recommended viscosity of oil. Hints for Cold Weather Operation If the engine will start, operate the engine until a minimum operating temperature of 80° C (176° F) is achieved. Achieving operating temperature will help prevent the intake valves and exhaust valves from sticking. Recommendations for the Coolant Provide cooling system protection for the lowest expected outside temperature. Refer to this Operation and Maintenance Manual, “Fluid Recommendations” for the recommended coolant mixture.
The cooling system and the lubrication system for the engine do not lose heat immediately upon shutdown. This means that an engine can be shut down for a period and the engine can still have the ability to start readily. In cold weather, check the coolant often for the correct glycol concentration in order to ensure adequate freeze protection. Install the correct specification of engine lubricant before the beginning of cold weather.
