Update Implement Hydraulics

Extend Valve Hoses

The weight transfer valve group is relocated to improve visibility from the tractor cab. Extend hoses prior to valve relocation. Extend hoses one at a time to eliminate the

need to mark hoses or trace routes. See “Hydraulic

Connectors and Torque” on page 70.

804-022C WASHER LOCK SPRING 5/8 PLT

and one:

202

806-105C U-BOLT 5/8-11 X 4 1/32 X 6

326. Relocate the valve group:

230

848-505C DECAL FRAME BACK PRESSURE PIC

328. Clean and dry the top surface of the wing tool bar on either side of the relocated valve group.

329. Select one each new:

979

848-504C DECAL WING DOWN PRESSURE PIC

980 848-505C DECAL FRAME BACK PRESSURE PIC

Apply

848-505C to the left of the valve group. Apply

848-504C to the right. Apply to the top or front of the tool bar left of the group. Apply to the top or front of the tool bar at right, or to the inside face of the gauge wheel mount (clear of lock channel storage).

High Pressure Fluid Hazard:

Wear gloves and eye protection. Open (“crack”) hydraulic connections slowly. Even with the systems set to Float prior to unhitching, there may still be residual pressure in some lines. if an injury occurs, seek immediate attention from a physician familiar with this type of injury.

Refer to Figure 90

330. Select one new:

975

816-480C HOSE WRAP 3.0-4.5 X 24LG VELCR

and three new:

938

800-035C CABLE TIE .31X28 8DIA 120LB

Close the wrap

on itself around the three hoses clamped to the wing. Adjust the wrap position so that the ends are across the front-to-rear wing tube near the wing extensions, and across the next frontto-rear rib toward the outside.

Fold the wrap around itself. Secure it with the ties.
