BEARING-SLEEVE 4E6378 - Caterpillar

Receiving Inspection
If the generator is received during cold weather, allow the unit to reach room temperature before you remove the protective packing material. Warming the generator to room temperature will prevent the following problems:
Water condensation on cold surfaces
Early failures due to wet windings
Early failures due to wet insulating materialsUnpacking
Moving the Generator
Improper lift rigging can allow unit to tumble causing injury and damage.
Do not use the engine lifting eyes to remove the engine and generator together.
Unpack the equipment with care in order to avoid scratching painted surfaces. Move the unit to the mounting location. The unit can be moved by either of the following methods:
Attach an overhead crane to the lifting eye that is installed on the generator package.
Use a lift truck in order to lift the generator. The hoist and the hoist cables should have a rating that is greater than the weight of the generator. When the unit is moved, ensure that the generator is completely supported by the lift truck's fork tines. Also ensure that the generator is balanced on the lift truck's fork tines. Slide the fork tines beneath the attached skid in order to lift the generator. Location
The location of the generator must comply with all local regulations. The location of the generator must also comply with all special industrial regulations. Locate the generator in an area that meets the following requirements:
Clean
Dry
Well ventilated
Easily accessible for inspection and maintenanceDo not obstruct air inlet openings. Do not obstruct discharge openings. Coolant flow must reach these openings. If the generator is exposed to harsh environmental conditions, the generator can be modified in the field in order to add filters and space heaters. In addition, a more rigid periodic maintenance schedule should be established.Remote Fuel Tanks and Auxiliary Fuel Tanks
Connect the generator to a remote fuel tank or an auxiliary fuel tank, if necessary. The tank should have good clean fuel and there should be provisions for draining water and sediment from the fuel tank. Refer to this Operation and Maintenance Manual, "Fuel Tank Water and Sediment - Drain".Connect the tank to the fuel supply fitting and the fuel return fitting on the generator set.Electrical Measurements
Measure the insulation resistance of each winding if the generator was exposed to the following conditions:
Rapid changes in temperature
Freezing
Wet climate during shipment
Wet climate during storageRefer to this Operation and Maintenance Manual, "Insulation - Test".Note: These tests should be conducted prior to any power connections or control connections that are being made.
