PUMP GP-GEAR 6E4772 - Caterpillar

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. When the temperature is below 13 °C (55 °F), Caterpillar recommends the use of the following starting aids before you start the engine:
Jacket Water Heater
Crankcase Oil HeaterNote: The fluid that is heated must be continuously circulated. This will help to prevent localized overheating of the fluid.Jacket water heaters are available for cold weather starting. 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 Caterpillar dealer for more information on the starting aids that are available for cold weather starting.Note: Engines that are started at temperatures below 13 °C (55 °F) without starting aids may damage internal components.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 very cold temperatures.Air Starting Motor
Note: The maximum air pressure for starting must not exceed 1030 kPa (150 psi).To start the engine at colder temperatures, the following conditions may be necessary:
Maximum air pressure for the starting motor
An additional volume of airStarting With Ether
Personal injury or property damage can result from alcohol or starting fluids.Alcohol or starting fluids are highly flammable and toxic and if improperly stored could result in injury or property damage.
Excessive starting fluid can cause piston and ring damage.Use starting fluid for cold starting purposes only.Do not use excessive starting fluid during starting or after the engine is running.
The optional ether starting aid is controlled through the electronic control module (ECM). This is the only method that is recommended for the injection of starting fluid.An ether starting aid is available as an option. Under the following conditions, the ECM will automatically inject ether during cranking:
The crankshaft is rotating.
The jacket water coolant temperature is less than 10 °C (50 °F).Additional injections of ether may be necessary in order to achieve normal operation at low idle rpm. The instrument panel will have a "STARTING AID" switch. The switch is normally in the "AUTo" position. After the engine has started, the operator can inject additional ether by holding the switch in the "MANual" position. The ECM will control the amount of ether that is injected. Ether can be injected by this method under the following conditions:
The engine speed is less than 1900 rpm.
The jacket water coolant temperature is less than 10 °C (50 °F).
