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

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

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

  1. 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.

  2. Permit only one operator on the machine.

  3. Block the front tracks and the rear tracks of the machine.

  4. Place a barrier around the machine in order to keep personnel away from rotating machinery.

  5. Remove the bucket and/or any other worktools connected to the lift arms.

  6. 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.

  4. Remove the Cover from the right-hand lift arm by removing the screws and the bolt on top and on the side of the cover, respectively. Set aside for reinstallation. Pull the end of the Harness As. from underneath the right-hand lift arm and continue to route the Harness As. towards the slot on the Cross Plate that joins the lift arms in front of the machine. Refer to Illustrations 6 and 7.

    Note: Note the lower portion of harness (14) is thicker.

  5. Continue to route the Harness As. from the hole behind the Plate that joins the lift arms. Then pull the Harness towards the previously installed sensor assembly. Connect the sensor assembly (21) to the LE-C3 connector on the 421-4206 Sensor Harness As. Secure the connection with one Cable Strap (4) to the slot on bracket (15). Ensure that the connection matches the one shown on Table 5. Refer to Illustrations 7, 8, and Illustration 1 "Area C".

  6. 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.

  7. Use seven straps (8) to secure the harness to the Tilt Lines on the locations shown in Illustration 10.

  8. Start machine, raise the lift arms, and secure the arms with the service brace. Refer to the Disassembly and Assembly manual for your machine. See Section "Reference Material" for more details.

  9. Lift the cab and secure. Refer to the Operation and Maintenance Manual, "Cab Tilting" or Disassembly and Assembly manual for your machine. See Section "Reference Material" for more details.

  10. Release the system pressure before continuing the installation. Refer to Testing and Adjusting, "Hydraulic System Pressure - Release" for the proper procedure.

    1. Position plate (19) onto the inside of the right tower in the location and orientation shown in Illustration 15. Ensure that the weld studs are oriented towards the right side of the machine. Use the shape of plate (19) as a template to achieve the right location. Carefully weld plate (19) with a 2 mm (0.1 inch) fillet on the locations indicated above.

      Reference: Refer to Cat® Spec 1E0099S if needed.

      Note: 435-8993 Sensor and Mounting (20) is not pre-assembled. Refer to the section titled "Assembly Procedure for the 435-8993 Sensor and Mounting", in this manual for the assembly procedure.

  16. Install sensor group (20) onto the inside of the right tower by using the listed hardware in Illustration 2.

    Note: This step is for machines that already have the hole pattern shown in Illustration 14 and do not need plate (19).

    When sensor group (20) is installed, proceed to Step 17.



    Illustration 18g03696445

  17. Inspect the top of the right lift arm on the rear of the machine, on the location shown in Illustration 18. If the lift arm DOES NOT have the hole pattern shown in Illustration 18, complete the installation of 435-8993 Mounting and Sensor Gp (20) as indicated in Step 18.

    If the lift arm DOES have the hole pattern shown in Illustration 18, then proceed with Step 19.

  18. Place the bracket (26) (part of the Mounting and Sensor Gp.) on top of the lift arm in the orientation and on the location shown in Illustration 19. Using the bracket as a template, mark the center location of each hole of the bracket onto the lift arm. Remove bracket (26) and drill three 9.3 +0.1/-0.2 mm (0.366 +0.004/-0.008 inch) holes on the marked locations on the lift arm. Use bolts (10) to attach the bracket. Torque the bolts to 40 +4/-0 N·m (30 +3/-0 lb ft).

  19. Place the bracket (26) (part of the Mounting and Sensor Gp.) on top of the lift arm on the location shown in Illustration 19. Use bolts (10) to attach the bracket. Torque the bolts to 40 +4/-0 N·m (30 +3/-0 lb ft).

    Note: This step is for machines that have existing holes for bracket (26).

  20. If the serial number of the machine where this kit is being installed corresponds to any of the serial numbers listed in Table 8, then install the 422-5585 Sensor Harness As as indicated in Steps 20a through 20c. If the serial number of the machine is not listed in Table 8, then proceed with Step 21.

  25. Enter the Cab and locate the Switch Cover, which is part of the control panel. Remove the Switch Cover from the control panel.

    Note: Movement of the Switch Cover will be hindered by the connections behind the switch cover. Exercise caution when removing the Switch Cover.

    Note: Use a thin blade screwdriver in order to release the locking tab on the sides of the Switch Cover. Then, withdraw the Switch Cover from the panel.

  26. Switch Cover (H) has provisions for four rocker switches. Remove plug (J) from the location on switch cover (H) as shown in Illustration 26.

  27. Carefully pull out the connector L-C10 from the Panel Harness As. by pushing the connector from the back of the Switch Cover. Install 263-5417 Rocker Switch (9) onto the connector and push the Rocker Switch into the new opening from the front of the Switch Cover. Push the Rocker Switch until the locking tabs on the Rocker Switch are engaged. Ensure that the connection corresponds to the one in Table 12.
