Backhoe Fit-Up Kit

1. Park the machine on a level surface.

2. Engage the parking brake.

3. Lower the loader arms.

4. Shut off the engine, remove the key, and allow the machine to cool.

5. Open the rear-access cover and engine hood.

6. Turn the battery-disconnect switch to the OFF position.

7. Remove the cover plate by removing the 3 bolts holding it in place (Figure 1).

   Note: Retain the cover plate and corresponding bolts for later installation.

   

   Figure 1

   1. Cover plate

Parts needed for this procedure:

1. Tilt the traction unit attachment mount plate flat and gently rest the attachment mount plate on top of a block.

2. Place a block in front of the mount plate so that it cannot swing forward when you remove the tilt-cylinder pin.

   Caution

   When you remove the tilt-cylinder pin, the mount plate may swing forward, crushing your feet or hands, or those of bystanders.

   Place a block in front of the mount plate before removing the tilt-cylinder pin.

3. Remove the bolt and nut securing the upper tilt-cylinder pin on the traction unit (Figure 2).

4. Using a hammer and punch, remove the tilt-cylinder pin.

5. Install the new pin into position and secure it with the bolt and nut removed previously, using the middle hole on the pin (Figure 2).

6. Grease the pin using the fitting on the tilt cylinder.

   Note: Leave the new pin installed, even when the backhoe is removed.

Parts needed for this procedure:

1. Install the quick-attach plate onto the backhoe using 2 small bolts, 4 small washers, 8 large bolts, 24 large washers, 8 spacers, and 10 nuts (Figure 3). Torque the bolts to 94 to 102 Nꞏm (70 to 75 ft-lb).

2. Connect the traction unit receiver plate to the backhoe quick-attach plate and engage the quick-attach pins; refer to the traction unit Operator’s Manual.

3. Install a tie-down link as shown in Figure 4. Secure the tie-down link with 2 pin locks.

4. Repeat step 3 on the other side of the machine.

5. Connect the hydraulic hoses; refer to the traction unit Operator’s Manual.

Parts needed for this procedure:

Note: Use the jumper wires on traction units with serial number 3999999999 and below only.

1. Plug the fit-up kit harness connector into the backhoe electrical harness connector (Figure 5).

   Note: When you are not using the backhoe, ensure to install the electrical harness cap on the backhoe end of the fit-up kit harness.

2. Route the fit-up kit electrical harness alongside the hydraulic hoses as shown in Figure 5.

3. Route the harness through the hydraulic hose access hole into the underside of the control panel (Figure 5).

   Note: Use the hydraulic hose tie downs to secure the harness.

4. Open the rear-access cover.

5. For traction units with serial numbers 3999999999 and below:

   1. Plug the 2 jumper wires into the corresponding fit-up kit harness connectors (Figure 6).

      

      Figure 6

   2. Under the control panel, remove the traction unit harness terminal from the ignition switch (Figure 7).
