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°. Eyebolts and brackets should never be bent and should only be loaded in tension.
Use a hoist to remove heavy components. Lift the engine by using an adjustable lifting beam. All supporting members (chains and cables) should be parallel to each other, and as near perpendicular as possible to the top of the object being lifted.Some removals require the use of lifting fixtures to obtain proper balance and to provide safe handling. To remove the engine, use the two lifting eyes on the engine.Lifting eyes are designed for the arrangement as sold. Alterations to lifting eyes and/or arrangement weight make the lifting devices obsolete.If you make alterations, you are responsible for providing adequate lifting devices.Engine Storage
If the engine will not be or has not been started for several weeks, the lubricating oil will drain from the cylinder walls and piston rings.If an engine remains out of service and its use is not immediately planned, special precautions should be taken. Rust can form on the cylinder liner surface, which will increase engine wear and may result in shorter engine life.To prevent this problem from becoming excessive, be sure all lubrication recommendations mentioned in the Maintenance Schedule 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 -20°F (-29°C).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, form SEHS9031 for more detailed information on engine storage.
