Think Safety
Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly. Improper operation, lubrication, maintenance, or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any lubrication, maintenance, or repair on this product until you have read and understood the operation, lubrication, maintenance, and repair information. Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons.
Introduction European Union Compliant, CE Marked
The hazards are identified by the Safety Alert Symbol and followed by a Signal Word such as “DANGER”,“WARNING”, or “CAUTION”. The Safety Alert “WARNING” label is shown below.
Important Safety Information
A non-exhaustive list of operations that may cause product damage are identified by “NOTICE” labels on the product and in this publication.

Operation Section
Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this publication and on the product are therefore, not all inclusive. If a tool, procedure, work method, or operating technique that is not recommended by Caterpillar is used, the operator must be sure that the procedures are safe. The operator must also be sure that the product will not be damaged or made unsafe by any unspecified procedures.
The Operation Section is a reference for the new operator and a refresher for the experienced operator. Photographs and illustrations guide the operator through correct procedures for using the tool group. Operating techniques outlined in this publication are basic. Skill and techniques develop as the operator gains knowledge of the service tool and tool capabilities.
The information, specifications, and illustrations in this publication are based on information that was available at the time that the publication was written. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete and most current information before you start any job.
Maintenance Section The Maintenance Section is a guide to tool inspection, cleaning, storage, and tool disposal.
Safety Section Safety Icon Nomenclature
When replacement parts are required for this product, Caterpillar recommends using Cat replacement parts or parts with equivalent specifications including, but not limited to physical dimensions, type, strength, and material.
Personal Protection/Important Information
Literature Information This manual contains safety information, operation instructions, and maintenance information and should be stored with the tool group. Some photographs or illustrations in this publication may show details that can be different from your service tool. Guards and covers might have been removed for illustrative purposes. Continuing improvement and advancement of product design might have caused changes to your service tool, which are not included in this publication. Whenever a question arises regarding your service tool or this publication, consult Dealer Service Tools (DST) for the latest available information.

420-2048 Adjustable C-Frame Assembly Lifting Device (A) Expanded (B) Contracted
The 420-2048 Adjustable C-Frame Assembly is a C-Style lifting device. The tool is used to remove and install various pumps and motors, final drives, and other wide variety of components. It is used with a suitable hoist or lifting device and is adjustable in horizontal and vertical directions. The following features provide maximum versatility:
• Vertical tube adjusts to different lengths. Two bolts, with nuts and washers lock the tube at the desired vertical position.
3
Nomenclature
• Vertical adjustments are made manually by
detaching nuts and bolts, sliding inner tube to desired location, and tightening the bolts and nuts.
• Top and bottom horizontal tubes are adjustable in horizontal directions.
• Horizontal adjustments are made using a 7/8" wrench.
• Internal ACME threaded rods in both of the
horizontal tubes adjust extension arms to achieve center of gravity, even under a load.
Note: For additional information on specific applications, refer to the appropriate service manual.

1. Identify the load and weight of the machine component to be lifted. Do not exceed the Working Load Limit (WLL).
3. After achieving desired length, make sure that bolts are fully inserted and tightened with nuts to standard torque.
2. Make sure that the lifting eyebolt is fully inserted. Tighten to standard torque.

4. Identify and measure the desired vertical length of the tooling required for the operation and adjust the inner vertical tube at the desired settings before loading the tool onto a suitable hoist or lifting device. Note: The Working Load Limit (WLL) of the tooling changes as the vertical length of the tooling changes. Note: The bolts and nuts used to keep the vertical tubes at the desired lengths should be tightened to standard torque before proceeding to the next step. Note: This step requires the tool to be laying flat on the surface or ground.

7. Turn the hex nuts (5) with a 22.22 mm (7/8 in) hand wrench until the desired horizontal location is achieved.
Note: The Working Load Limit (WLL) of the hoist or lifting device used for this step should be more than the weight of the machine component being lifted and the tooling used to lift it.
Note: The Working Load Limit (WLL) of the tooling changes as the horizontal length of the tooling changes.
6. Refer to the appropriate Disassembly and Assembly service manual for the machine component to be lifted.
Note: Avoid getting trapped between tooling and the machine component. Stay a safe distance away from the tooling and the machine component during the installation and removal of the machine component. Note: Operate the wrench by hand only, and when the tool is in a stable condition.

position. Store the tool laying flat or hanging from appropriate hooks to prevent falling.
• At the end of the operational life of the tool, destroy the tool and dispose of as scrap.
Illustration 10
g03322272
• Inspect all welds and check for damaged, cracked, or bent components. Inspect tooling prior to each use. If damage is found, destroy the tool and dispose of as scrap. Replace damaged tool with new product.
• Do not use unless the Working Load Limit (WLL) identification markings are legible.
• Do not use if lifting holes in vertical tubes are elongated.
• Do not use if hardware is damaged or missing. • Have the tools inspected annually by an approved dealership inspector.
Maintenance • Periodically lubricate the threaded rod using an appropriate lubricant.
• Periodically inspect the threaded holes in the
horizontal tube extension arms. If threads are damaged, destroy the tool, dispose of as scrap, and replace with new product.
Cleaning • Clean the tooling with a non-solvent based cleaner. Storage • Store the tooling in a clean, dry location to prevent rust or corrosion. Tooling can be damaged by moisture or high humidity.
• Internal threads can also be damaged by moisture or high humidity. Store the tool indoors in a clean, dry location with the extension arms retracted.
