Removing the Lift Cylinder (continued)
4. For assembly purposes, label all the hydraulic connections. Clean the
hydraulic connections before loosening the hydraulic lines from the lift
cylinder.
CAUTION
Before opening the hydraulic system, operate all the hydraulic
controls to release system pressure and avoid injury from the
pressurized hydraulic fluid; refer to
Hydraulic System (page 6–8)
.
WARNING
Ensure that the cutting units are fully lowered before loosening the
hydraulic lines from the lift cylinders.
If the cutting units are not fully lowered as the hydraulic lines are
loosened, the cutting units may drop unexpectedly.
5. Disconnect the hydraulic hoses from the fittings in the lift cylinder that is to be
removed. Allow the hoses to drain into a suitable container. Remove and
discard the O-rings from the fittings.
6. Install clean caps or plugs on the hydraulic hoses and fittings to prevent
contamination.
7. Remove 1 retaining ring (item 4 in
) and thrust washer from the
cylinder slide pin. Pull the pin from the lift cylinder and lift arm. Locate and
retrieve the second thrust washer.
8. Remove the flange-head screw (item 15 in
) and flat washer that
secure the lift cylinder to the cylinder pin.
9. Remove the lift cylinder from the cylinder pin and frame.
10. If the hydraulic fittings are to be removed from the lift cylinder, mark the fitting
orientation for assembly purposes. Remove the fittings from the lift cylinder
and discard the O-rings from the fittings.
Installing the Lift Cylinder
1. If the hydraulic fittings were removed from the lift cylinder, lubricate new
O-rings with clean hydraulic fluid, position the O-rings to the fittings, and
install the fittings into the lift cylinder ports; refer to
Fittings (SAE Straight Thread O-Ring Fitting into the Component Port) (page
6–13)
. Ensure that the fittings are orientated correctly.
2. Position the lift cylinder to the frame.
Note:
The lift cylinder barrel end should be attached to the machine frame.
3. Slide the barrel end of the lift cylinder onto the cylinder pin (item 1 in
4. Apply medium strength threadlocker to the threads of the flange-head screw
(item 15 in
). Secure the cylinder with the flange-head screw and
flat washer. Torque the flange-head screw to
105 to 126 N∙m (77 to 93 ft-lb)
.
5. Align lift cylinder to the lift arm mounting holes. Slide the cylinder slide pin
(item 6 in
) (with a thrust washer and retaining ring installed on
