Information:
Engine Lifting
When it is necessary to remove a component on an angle, remember that the capacity of an eyebolt is less as the angle between the supporting members and the object becomes less than 90 degrees. Eye Bolts 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 equipped with the engine.The lifting eyes are designed for the engine arrangement as sold. Modifying the lifting eyes and/or engine arrangement weight renders the lifting eyes and devices obsolete.If you modify the lifting eyes and/or engine arrangement 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 proper engine and fuel tank lifting.Engine Storage
The following Engine Storage procedures and recommendations minimize the possibility of damage to engines stored for one year or less.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.Special precautions should be used with engines remaining out of service for extended periods.After one year, a complete protection procedure must be followed if the engine is kept in storage longer. 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 it will be impossible to start the engine periodically, consult your Caterpillar dealer for instructions to prepare your engine for longer storage periods.Refer to Storage Procedures For Caterpillar Products, SEHS9031, for more detailed information on engine storage.Generator Storage Procedure
When a generator is stored, moisture may condense in the windings. Use a dry storage space and space heaters to minimize condensation. Refer to: Service Manual for SR4 Generators, SENR3985, or Special Instruction, SEHS9124, Cleaning and Drying of Caterpillar 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. It may be necessary to megger more frequently if the environment is extremely humid or salty.
