SPACER 5S9062 - Caterpillar

Receiving Inspection
Two-bearing generators are completely assembled prior to shipment. 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 and Storage
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 eyebolts that are installed on the generator frame.
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. Storage
Short Time Storage
If the generator is not installed in the operating location immediately, the generator should be stored in a clean area. Also, the generator should be stored in a dry area. This area should also have the following conditions: low humidity, stable humidity and stable temperature. Generator space heaters should be energized in order to keep condensation from the windings. All accessory equipment that is supplied with the unit should be stored with the generator. The combined unit should be covered with a durable cover in order to protect against the following contaminants:
dust
dirt
moisture
other airborne abrasive materialLong Time Storage
A storage period in excess of six months should be preceded by the following preparation:
Install desiccant bags inside the exciter's cover and install desiccant bags inside the screen of the fan.
Seal the unit in a covering of plastic or other material that has been designed for that purpose.
Adequately tag the generator. This will ensure that preservative greases and desiccant bags are removed before the unit is placed in operation.Bearing Inspection
Ball bearing generators use grease. This grease is subject to deterioration. If the generator is stored longer than one year, new ball bearings should be installed. These bearings should be greased to the proper level prior to being put into operation. If inspection indicates that bearings are free of rust or corrosion, and no noise or excessive vibration appear on start-up, replacement is not necessary. 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
