PIPE 1C7584 - Caterpillar

Start By:a. connect steering frame lock link1. Disconnect the attachment tool from the coupler assembly. 2. Raise the lift arms, and put them in position on tooling (A). 3. Remove the cover plate from the front frame.
Release all the pressure in the hydraulic system prior to disconnecting any hydraulic lines or removing any loader linkage pins. If the hydraulic oil pressure is not released completely, oil can spray out of the oil lines under high pressure. Also, there will be binding of the loader linkage pins in their bores. After removal of any pins, the loader linkage can separate suddenly. Failure to release system pressure completely can cause personal injury.
4. Make sure the hydraulic system pressure is released.5. Disconnect two tube assemblies (1) and (3). Disconnect two hose assemblies (4).6. Disconnect wire connector (2). 7. Disconnect tube (5) and two tube assemblies (6). Remove two bolts (7), and remove diverter valve (8) from the machine.8. Install the diverter valve in the reverse order if removed.End By:a. separate steering frame lock linkDisassemble & Assemble Diverter Valve (Front Implement)
Start By:a. remove diverter valve (front implement) 1. Remove housing (6) and valve stem (7) from valve body (2). Remove seal (8) from housing (6).2. Compress spring (9), and remove two retainers (10) from stem (7).3. Remove nut (5), washer (4), coil assembly (3) and cartridge assembly (1).4. Remove lockring (11) from cartridge assembly (1).5. Remove body (16), spool assembly (15) and spring (14) from the cartridge. Remove seal (12), two seals (13) and two rings (17). The following steps are for assembly of the diverter valve (front implement).6. Inspect all seals, rings and valve parts for wear or damage. Make replacements if necessary. Be sure to check the two O-ring seals inside the bore of valve body (2) for stem (7).7. Make sure all parts are clean and free of dirt and foreign material. Put clean hydraulic oil on all parts during assembly.8. Assemble the diverter valve in the reverse order.9. Make sure rings (17) are on the right side of seals (13) as shown.10. Tighten cartridge assembly (1) to a torque of 22 to 27 N m (16 to 20 lb ft).11. Tighten nut (5) to a torque of 2.8 to 2.9 N m (25 to 26 lb in).End By:a. install diverter valve (front implement)
