BEARING 1443130 - Caterpillar

2. Put identification marks on hose assemblies (1) for installation purposes. The number of control valves and hoses will vary with the amount of implements on the machine.3. Remove hose assemblies (1) from the implement control valves. Plug the fittings on the hoses in order to prevent the loss of hydraulic oil, and to keep dirt out of the hydraulic system. 4. Remove bolts (2) from cover (3). Raise cover (3) up and out of the way. Pull floor mat (4) back and out of the way. 5. Remove four bolts (7) from control valve linkages (8). Move four control valve linkages (8) up and out of the way.6. Remove bolts (5) and the washers from cover (6). Remove cover (6) from the floor of the cab. 7. Remove bolts (9), bolt (10), the washers, the nuts and the rubber mountings that hold the implement control valves. Remove the implement control valves from the mounting plates.8. Repeat Steps 2 through 7 for the implement control valves located on the other side of the machine.Install Implement Control Valves
1. Make sure all of the components of the implement control valves are clean prior to installation. During the installation, check the condition of all the O-ring seals used on the hydraulic hoses that were disconnected. If any of these seals are damaged, use new parts for replacement. 2. Position the implement control valves to their original locations and install bolts (9), bolt (10), the washers, the nuts and the rubber mountings in order to secure the valves to the mounting plates. 3. Install cover (6), bolts (5) and the washers that hold cover (6) to the floor of the cab.4. Install control valve linkages (8) and bolts (7) that hold the linkages to the implement control valves. 5. Position floor mat (4) to its original location on the floor of the cab. Install cover (3) and bolts (2). 6. Install hose assemblies (1) to their original locations on the implement control valves.7. Repeat Steps 2 through 6 for the other side.8. Fill the hydraulic tank with oil to its correct level. Refer to the "Operation & Maintenance Manual" for the proper procedure.Disassemble Implement Control Valve
Start By:a. remove implement control valve 1. Put identification marks on cover (2), valves (5), and manifold (4), showing the location of the components, for assembly purposes. Remove bolts (1) and cover (2) from the control valve. 2. Remove bolts (3) and manifold (4) from the control valve. The number of valves may vary in order to match the number of implements.3. Separate individual valves (5) and seal plates (6) from the unit. 4. Remove bolts (7) and washers from valve (5).5. Remove cover (9), O-ring seal (10) and spring (11) from valve (5). 6. Remove bolts (8), the washers and control assembly (12) from valve (5). 7. Remove bolts (13), the washers and cover (14) from control assembly (12). 8. Remove O-ring seal (15) and lever (16) from control assembly (12).9. Remove lever assembly (17)
