WHEEL & FINAL DRIVE GP 4V6531 - 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 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 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 eyes that are installed on the generator package.
Use a lift truck 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 supported by the lift truck fork tines. Also ensure that the generator is balanced on the lift truck fork tines. Slide the fork tines beneath the attached skid to lift the generator.Storage
Short Time Storage
If the generator is not installed immediately, store the generator in a clean area. This area should also have the following conditions: low humidity, stable humidity, and stable temperature. Space heaters must be energized 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 to protect against the following contaminants:
Dust
Dirt
MoistureLong Time Storage
Note: During storage, the generator and gearbox shafts should be rotated a minimum of every 6 months to avoid bearing damage.A storage period more than 6 months should be preceded by the following preparation:
Install desiccant bags inside the exciter 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 tag will ensure that preservative greases and desiccant bags are removed before the unit is placed in operation.
Drain coolant and oil from the gearbox heat exchanger.
Fill the gearbox to the FULL oil level mark on the oil level gauge with appropriate preserving oil with VCI additives.
If possible, rotate both gearbox shafts several times to make sure that all bare metal surfaces are coated with preserving oil.
Rotate both gearbox shafts at least one complete turn to change position of the rolling elements in the bearings.
Ensure that all gearbox openings, ports, and labyrinth seals are closed. Cover the unit to avoid debris and dust ingress into the unit.
Prior to recommissioning, flush the gear box. Follow the steps bellow to flush the gearbox:
Drain the gearbox of all previous lubricants and/or preservatives.
Fill the gearbox with oil to theFULL oil level mark on the oil level gauge. Refer to this Operation and Maintenance Manual , Fluid Recommendations section for the correct oil to use in the gearbox.
Operate the gearbox unloaded for 30 minutes.
