Important Safety Information
| |
| Illustration 1 | g02139237 |
Work safely. 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. Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. AVSpare cannot anticipate every possible circumstance that might involve a potential hazard. Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not recommended by AVSpare is used, ensure that it is safe for you and for other people to use. Ensure that the product will not be damaged or the product will not be made unsafe by the operation, lubrication, maintenance, or the repair procedures that are used.

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.
The hazards are identified by the “Safety Alert Symbol” which is followed by a “Signal Word” such as “DANGER”, “WARNING” or “CAUTION”. Refer to Illustration 2 for an example of a “WARNING” Safety Alert Symbol.
| |
| Illustration 2 | g00008666 |
This safety alert symbol means:
Pay Attention!
Become Alert!
Your safety is Involved.
The message that appears under the safety alert symbol explains the hazard.
Operations that may cause product damage are identified by "NOTICE" labels on the product and in this publication.
AVSpare cannot anticipate every possible circumstance that might involve a potential hazard. The safety information in this document and the safety information on the machine are not all inclusive. Determine that the tools, procedures, work methods, and operating techniques are safe. Determine that the operation, lubrication, maintenance, and repair procedures will not damage the machine. Also, determine that the operation, lubrication, maintenance, and repair procedures will not make the machine unsafe.
The information, the specifications, and the illustrations that exist in this guideline are based on information which was available at the time of publication. 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, most current information before you start any job. AVSpare dealers can supply the most current information.
Summary
The ring and stator carrier assemblies used with rotating clutches in the transmissions may be damaged by debris, excessive pressures, high temperatures, or lack of lubrication. These conditions cause excessive heat build-up and wear of the Vespel seal and seal groove, resulting in leakage. The wear is normally on the pressure side of the groove of the number two clutch seal ring.
This guideline provides the procedures necessary to determine the reusability of the ring and stator carrier assemblies. Life will vary depending on application, load, lubrication, and environment.
This guideline contains the latest standards of engineering, which will help minimize owning and operating costs. A part is expected to reach the next Planned Component Rebuild (PCR) if the part meets the specifications within this guideline and the part is intended for a similar application. Use this guideline to determine whether a part should be reused. Do not install a part that is not reusable. During reconditioning, correct any condition that might have caused the original failure.
The dimensions and tolerances provided are to return a part / component to specification. The dimensional information alone is not solely used to condemn a part from reuse. Follow visual inspections and the "Visual Inspection" section for further guidance.

Preparation Recommendations
|
|
Personal injury can result when using cleaner solvents. To help prevent personal injury, follow the instructions and warnings on the cleaner solvent container before using. |
|
|
Personal injury can result from air pressure. Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing. Maximum air pressure at the nozzle must be less than |
Note: Clean exterior of the ring and stator carrier assemblies prior to disassembly to minimize cross-contamination.
- Before you inspect a part, clean the part thoroughly to ensure that all components are free from rust, oil, burrs, and debris prior to inspection. A surface irregularity can hide the indication of an unacceptable defect.
- Use a proper lifting device to provide safety to the operator. Also, use a proper lifting device to prevent damage to the part when you lift the part.
- Wash each carrier assembly separately. When several parts are washed together, machined surfaces can be damaged.
- During cleaning, do not damage machined surfaces.
- Use pressurized air to dry the carrier assemblies.
- Put hydraulic oil on all machined surfaces to prevent rust or corrosion if inspection is not done immediately after cleaning. Carefully store the parts in a clean container.
- Note: Application of hydraulic oil to machined surfaces is a good option for short-term storage, if long-term storage is necessary then follow long-term storage guidelines. Refer to SEHS9031Special Instruction, "Storage Procedure for AVSpare Products".
- Inspect all flange mating surfaces for fretting. Ensure that flange mating surfaces are true and free from raised material resulting from rust, nicks, and dents.
Standardized Parts Marking Procedure
Reference: , SEBF8187Reuse and Salvage Guidelines, "Standardized Parts Marking Procedures".
The code is a Cat standard and is used to record the history of a component. The code will identify the number of rebuilds and hours at the time of each rebuild. This information is important and should be considered for any decision to reuse a component.
Ensure that the mark is not covered by a mating part or on any critical location. Use a metal marking pen to mark the code onto the component.
| NOTICE |
|---|
|
Do not use numbering stamp punches to mark internal components. The impact from striking the stamp will cause an abnormal stress riser. The added stress riser may cause premature part failure. |
| |
| Illustration 3 | g06124077 |
|
DO NOT use numbering stamp punches to mark internal components. | |
The procedure for marking components is a Cat standard. This code is helpful when the machine is sold into a different territory after the first rebuild. During an overhaul, the previous code of a part should never be removed.
Example 1
| |
| Illustration 4 | g06274624 |
|
Example of | |
Illustration 4 shows code (1-15). The first number (1) indicates that the carrier assembly had been rebuilt once. The second number (15) indicates that there were 15,000 hours on the gear at the time of rebuild.
Example 2
| |
| Illustration 5 | g06274630 |
|
Example of | |
Illustration 5 shows code (1-12) and code (2-10). Code (2-10) represents the information from the second rebuild. The first number (2) indicates that the gear had been rebuilt twice. The second number (10) indicates that 10,000 hours accumulated on the gear between the first and second rebuild.
Note: Add the first and second rebuild hours to obtain the total number of hours for the gear in Illustration 5. In this example, the gear has a total of 22,000 hours.
