Description Of Change: The new torque converter group has smaller rollers and additional spring that prevents the roller from seizing, and increases the service life of one-way clutch.

Adaptable To: The following changes are adaptable to the products within the listed serial numbers, and are effective with all products after the listed serial numbers.

------ WARNING! ------

Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.


------ WARNING! ------

Access to this service point may require climbing on the equipment. Slipping or falling while climbing on the equipment could result in personal injury or death. Refer to the Operation and Maintenance Manual, Mounting and Dismounting topic for safety information.


------ WARNING! ------

Failure to use an approved access system during installation and removal of components could result in slipping and falling which could result in personal injury or death. To prevent injury or death, use an approved access system to reach the appropriate mounting locations of the components. Do not climb on the machine. Maintain three-points of contact and/or use a safety harness.


------ WARNING! ------

When removing a major component or attachment, ensure that it is properly blocked or secured before removing mounting hardware. An assembly that is disconnected without proper blocking may shift or fall, resulting in serious injury or death of personnel or machine damage.


------ WARNING! ------

Do not operate the machine if any guards or covers are missing or inadequately secured. Personnel could be seriously injured or machine damage may occur.


------ WARNING! ------

Check valves in the hydraulic system may allow pressure to exist in the hydraulic lines after the engine has been stopped. Pressure must be relieved prior to servicing the components of the hydraulic system. Failure to relieve pressure prior to servicing may result in personal injury.
