Removal (Fig. 91)<br />
1. Park machine on a level surface, lower cutting deck,<br />
stop engine, engage parking brake and remove key<br />
from the ignition switch.<br />
2. Read the General Pre<strong>caution</strong>s for Removing and<br />
Installing Hydraulic System Components at the beginning<br />
of this section.<br />
3. Remove deck covers as needed to allow access to<br />
lift cylinder hoses and fasteners.<br />
4. To prevent contamination of hydraulic system during<br />
lift cylinder removal, thoroughly clean exterior of cylinder<br />
and fittings.<br />
NOTE: To ease installation, label the hydraulic hoses to<br />
show their correct position on the lift cylinder.<br />
5. Disconnect hydraulic hoses from lift cylinder.<br />
6. Remove cap screw and lock nut that secure the lift<br />
cylinder clevis to the wing deck.<br />
7. Remove lock nut and flat washer from the tapered<br />
stud on the barrel end of the lift cylinder.<br />
8. Remove lift cylinder from deck assembly.<br />
9. Remove spherical bearings from lift cylinder clevis<br />
ends, if required.<br />
A. On shaft clevis, remove retaining ring and then<br />
press spherical bearing from clevis.<br />
B. On barrel clevis, remove retaining ring and then<br />
press tapered stud with spherical bearing and flange<br />
nut from clevis. Remove flange nut and then spherical<br />
bearing from stud.<br />
Installation (Fig. 91)<br />
1. If removed, install spherical bearings into lift cylinder<br />
clevis ends.<br />
A. On shaft clevis, press spherical bearing into clevis<br />
and secure with retaining ring.<br />
B. On barrel clevis, install spherical bearing on tapered<br />
stud and secure with flange nut. Torque flange<br />
nut from 30 to 40 in -lb (41 to 54 N -m). Install stud<br />
with spherical bearing into clevis and secure with retaining<br />
ring.<br />
2. Thoroughly clean tapered surfaces of lift cylinder<br />
stud and mounting boss on deck.<br />
3. Position lift cylinder to cutting deck. Insert tapered<br />
stud into deck mounting boss. Secure stud with flat<br />
washer and lock nut. Torque flange nut from 160 to 180<br />
ft -lb (217 to 244 N -m).<br />
4. Insert cap screw from the front of the deck through<br />
the deck brackets and cylinder shaft clevis. Secure cap<br />
screw with lock nut. Torque lock nut from 160 to 180 ft -<br />
lb (217 to 244 N -m).<br />
5. Attach hydraulic hoses to lift cylinder.<br />
6. Install any removed deck covers.<br />
7. Fill reservoir with hydraulic fluid as required.<br />
8. After assembly is completed, operate lift cylinder to<br />
verify that hydraulic hoses and fittings are not contacted<br />
by anything.<br />
