Remove cover (1) , wave washer (2) , screen (3) and magnetic tube assembly (4) .
Inspect the screen and magnets for large particles of debris. An excessive amount of debris may be an indication of possible failure. Also, oil contamination may require you to change the transmission oil. If large particles are found, consult your Caterpillar dealer for further analysis and additional guidance.
Do not drop or rap the magnets against any hard objects. Replace any damaged magnets.
Remove the magnets from the tube assembly.
Wash the magnets, the screen, and the magnetic tube assembly in clean, nonflammable solvent. Clean the magnets with a cloth, a stiff bristle brush or air pressure.
Install the clean magnets on the tube assembly. Refer to Illustration 2 for the arrangement of the magnets.
Inspect seal (5) . If the seal is damaged, replace the seal.
Assemble the screen and the magnetic tube assembly.Note: Screen must be assembled with "Assemble This End In" facing inward.
Inspect the screen and the magnetic tube assembly to ensure both are installed properly into housing.Note: Improper installation will cause the screen to seat too high in the housing and crush the screen when the cover is installed.
Install the wave washer and the cover.Note: Before tightening the nuts, apply pressure to center of cover. If the cover will not seat evenly over each stud, the screen and the magnetic tube assembly are not properly installed. If necessary, remove the cover and adjust the screen and the magnetic tube assembly and reinstall the wave washer and the cover.
Start the engine and operate the engine at low idle. Check for any leaks and make the necessary repairs.
Check the oil level in the transmission tank. If necessary, add oil. For the proper procedure, refer to Operation and Maintenance Manual, "Transmission Tank Oil Level - Check".
