BRACKET 3J4315 - Caterpillar

Starting fluid is required for temperatures below 0 °C (32 °F). The use of other optional cold starting aids is recommended for temperatures below −18 °C (0 °F).Electric Starting Motor
Maintain the proper level of electrolyte in the batteries. Keep the batteries fully charged.To maximize the battery power, heat the battery compartment or store the batteries in a warm location. Typically, batteries only have 50 percent of the capability at −10 °C (14 °F) versus 27 °C (80 °F).Extra battery capacity may be necessary for cold temperatures.Heaters
Note: Oil pan immersion heaters are not recommended for heating the lube oil. To ensure the compatibility of the components, only use equipment that is recommended by Caterpillar.Startability will be improved at temperatures below 12 °C (55 °F) with a starting aid. A jacket water heater may be needed and/or the crankcase oil may require warming.Note: The fluid that is heated must be circulated continuously. This procedure will help to prevent localized overheating of the fluid.A jacket water heater is available as an option for starting in temperatures as low as 0 °C (32 °F). The jacket water heater can maintain the water temperature at approximately 32 °C (90 °F). The heated water will help to keep the oil in the engine block warm enough to flow when the engine is started.When No. 2 diesel fuel is used, a fuel heater will maintain the temperature of the fuel above the cloud point. Fuel line insulation will help to maintain the fuel temperature.Consult your Cat dealer for more information on the starting aids that are available for cold weather starting.Air Starting Motor
Note: Air starters will require air pressure regulation if the air supply exceeds the air pressure requirements that are listed in table 1

Air Starter Maximum Air Pressure Requirements Air Consumption at Maximum Operating Pressure
Air Starter Configuration Maximum Operating Air Pressure
Right-Hand Air Starter with Oil Mist Detection 621 kPa (90 psi) 1606 SCFM (45.7 m3/min
Right-Hand Air Starter without Oil Mist Detection 690 kPa (100 psi) 925 SCFM (26.2m3/min
Left-Hand Air Starter 690 kPa (100 psi) 925 SCFM (26.2m3/min To start the engine at colder temperatures, the following conditions may be necessary:
Maximum air pressure for the starting motor
An extra volume of air
