Always inspect lifting eyebolts and all other lifting equipment for damage before performing any lifting.Never bend the eyebolts or the brackets. Never perform product lifting if components are damaged. Only load the eyebolts and the brackets under tension. Remember that the capacity of an eyebolt is less as the angle between the supporting members and the object becomes less than 90 degrees.When removing a component at an angle is necessary, only use a link bracket that is properly rated for the weight.
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. The chains and cables should be perpendicular to the top of the object that is being lifted.Some removals require lifting the fixtures to obtain proper balance and safety.To remove the engine ONLY, use the lifting eyes that are on the engine.Lifting eyes are designed and installed for the specific engine arrangement. Alterations to the lifting eyes and/or the engine make the lifting eyes and the lifting fixtures obsolete. If alterations are made, ensure that proper lifting devices are provided. Consult your Caterpillar dealer for information regarding fixtures for proper engine lifting.Engine and Factory Mounted CEM

View of front lifting location
Engines with a factory-mounted CEM with or without a factory-mounted radiator, can be lifted by the CEM front and rear bracket's load ring (provided) and using a certified spreader bar.Refer to the Special Publication, NENG2500, "Cat Dealer Service Tool Catalog" for the latest in lifting devise part numbers. Follow the safety instructions for the selected tool to ensure a safe lift. For most packages, the recommended spreader bar is 6V-6146 set at 142 cm (56 inch) with the lift hook locations set at about 3/4 of the way toward the front stop (closest to the front engine lift eye).Remove any ATAAC lines, air cleaners, or other attachments that would otherwise interfere with the lift chains or other lifting devises.The engine package center of gravity will change depending on the engine attachments. Adjust the spreader bar and chains as necessary to maintain a lift within 5 degrees of horizontal in all directions.Remove the front load ring before returning the engine to service, to prevent the last load ring from rubbing on the fan belt.Engine and Installed Radiator Only
The engine lifting eyes are rated to lift an engine with attached radiator, assuming a less than 5 degree tilt angle can be maintained. Be sure to use an appropriate spreader set so that lifting chains are perpendicular to the engine.Radiator Only
Detach the radiator, and mounting bracket at the engine front support. Add eyebolts or lifting brackets to the threaded holes marked for lifting.Clean Emission Module Lifting

Illustration 5 g03354117
typical example
Side B
Detach the Clean Emission Module (CEM) and use the lifting eyes attached to the CEM support for lifting. Care must be taken to identify the center of gravity of the CEM.
Do not attempt to use the radiator or CEM lift points to aid in the engine package lift.
