This Special Instruction provides information that is necessary to install the 422-3362 Work Tool Wiring (Self Level) Kit on the listed machines.
Do not begin installation of this kit until you have read and understand the instruction that is contained in this instruction.
Safety
At operating temperature, the hydraulic oil is hot and under pressure. Hot oils can cause burns. To prevent possible personal injury, release the pressure in the work tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits, and the hydraulic oil tank at the filler cap before any hydraulic lines or components are disconnected or removed. Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch. |
NOTICE |
---|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products. Dispose of all fluids according to local regulations and mandates. |
NOTICE |
---|
Keep all parts clean from contaminants. Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components. To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly. Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination. |
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 in order to perform these functions properly.

Machine Preparation
- Move the machine to a smooth horizontal location. Move the machine away from other machines and personnel. Lower the bucket to the ground. Stop the engine.
- Permit only one operator on the machine.
- Block the front tracks and the rear tracks of the machine.
- Place a barrier around the machine in order to keep personnel away from rotating machinery.
- Remove the bucket and/or any other worktools connected to the lift arms.
- If equipped with an Electronic Coupler, remove the two bolts that hold the guard onto the coupler assembly. Slide the guard out of place. Set aside for reinstallation.

( 14)421-4206 Sensor Harness As - Secure harness (14) onto the Coupler by removing the existing 7X-0818 Bolt, the 239-9833 Plate, and the 140-1339 Clamp on top of the Coupler. Route harness (14) through the empty slot on the Clamp closest to the right side of the machine. Reinstall the Clamp, Plate, and Bolt. Repeat this process for the second clamp located behind the Cross Plate that joins the lift arms. Refer to Illustration 9.
Note: The thicker portion of harness assembly (14) should fit in between both sets of Clamps as indicated in Illustration 9. The thinner portion should be routed towards the inside of the lift arms. This step ensures that the proper amount of slack is created to accommodate the rotation of the bucket and/or worktool.
