When it is necessary to remove a component, remember that the capacity of an eyebolt is less as the angle between the supporting members and the object becomes less than 90 degrees. Eyebolts and brackets should never be bent, and should only be loaded under tension.
Use a hoist to remove heavy components. Use an adjustable lifting beam to lift the engine. All supporting members (chains and cables) should be parallel to each other, and perpendicular as possible to the top of the object being lifted.Some removals require the use of lifting fixtures, to obtain proper balance and provide safe handling.To remove the engine only, use the lifting eyes that are on the engine.The lifting eyes are designed for the engine arrangement as sold. Modifying the lifting eyes and/or engine weight renders the lifting eyes and devices obsolete.If you modify the lifting eyes and/or engine weight, you are responsible for providing adequate lifting devices. Contact your Caterpillar dealer for information regarding fixtures for proper engine package lifting.Engine Lifting With Generator
Do not use the engine lifting eyes to remove the engine and generator together.
Lifting the engine and generator together requires special equipment and procedures. Contact your Caterpillar dealer for information regarding fixtures for proper lifting of your engine package.Engine Lifting With Fuel Tank
Lifting the engine along with a mounted fuel tank requires special equipment and procedures. Do not lift the unit with fuel in the tank. Contact your Caterpillar dealer for information regarding proper engine and fuel tank lifting.Engine Storage
When an engine is not started for several weeks, the lubricating oil drains from the cylinder walls and piston rings. Rust can then form on the cylinder liner surface, increasing engine wear and decreasing engine life. To prevent excessive engine wear:* Be sure all lubrication recommendations mentioned in the Maintenance Schedule intervals chart are completed.* If freezing temperatures are expected, check the cooling system for adequate protection against freezing. A 50/50 solution of Caterpillar (permanent-type) Antifreeze and approved water will give protection to -29°C (-20°F).If an engine is out of operation and if use of the engine is not planned, special precautions should be made. If the engine will be stored for more than one year, a complete protection procedure is recommended.Your Caterpillar dealer will have instructions for preparing your engine for extended storage periods.Refer to SEHS9031, Storage Procedures For Caterpillar Products, for more detailed information on engine storage.Generator Storage
When servicing or repairing electric power generation equipment:Make sure the unit is off-line (disconnected from utility and/or other generators power service), and either locked out or tagged DO NOT OPERATE. Remove all fuses.Make sure the generator engine is stopped.Make sure all batteries are disconnected.Make sure all capacitors are discharged.Failure to do so could result in personal injury or death.Make sure residual voltage in the rotor, stator and the generator is discharged.
When a generator is stored, moisture may condense in the windings. Use a dry storage space and space heaters to minimize condensation.To Remove Moisture
Drying does not always produce desired results. It may be necessary for the generator to be dipped and baked by a qualified rebuild shop.
* Energize the space heaters in the generator (if equipped).* Space heaters, of the same type used in marine applications, can be installed on generators (see the Parts Manual.) These heaters warm the windings to remove moisture. These heaters should be connected at all times in high humidity conditions, whenever the generator is not running.Refer to SEHS9124, Cleaning and Drying of Electric Set Generators, or contact your Caterpillar dealer.After Storage
Test the main stator windings with a megohmmeter:* Before the initial startup of the generator set* Every 3 months* if the generator is operating in a humid environment* If the generator has not been run under load for 3 months* or more*This is a guideline only. If the environment is extremely humid or salty, it may be necessary to perform the Megger Test more frequently. Refer to: * SEBU7050, SR4B Generators and Control Panels Operation and Maintenance Manual.
