Removal (Fig. 81)
1. Park machine on a level surface. Lower cutting units,
stop engine and engage parking brake. Remove key
from the ignition switch.
NOTE: The rear tire must be removed to allow sufficient
clearance to remove the steering cylinder from the ma-
chine.
WARNING
Before jacking up the machine, review and follow
Jacking Instructions in Chapter 1 − Safety.
2. Jack or lift rear wheel off the ground.
3. Remove rear wheel from the machine.
4. Thoroughly clean hydraulic hose ends and fittings on
steering cylinder to prevent hydraulic system contami-
nation.
WARNING
Before disconnecting or performing any work on
the hydraulic system, all pressure in the system
must be relieved. See Relieving Hydraulic Sys-
tem Pressure in the General Information section
of this chapter.
5. Label the hydraulic hoses to show their correct posi-
tion on the steering cylinder. Remove hydraulic hoses
from steering cylinder.
6. Remove the two (2) jam nuts or the flextop lock nut
from both steering cylinder ball joints.
7. Use a suitable tool (pickle fork) to separate the ball
joints from the machine.
8. If hydraulic fittings are to be removed from steering
cylinder, mark fitting orientation to allow correct assem-
bly. Discard O−rings from removed fittings.
9. If needed, remove ball joints from steering cylinder.
NOTE: Replace the greasable style ball joints with the
non−greasable style. A replacement hydraulic cylinder
will come with non−greasable ball joints installed. Use
one flextop lock nut to secure non−greasable style ball
joints.

Installation (Fig. 81)
1. If removed, install ball joints into steering cylinder.
2. Lubricate and place new O−rings onto removed
steering cylinder fittings. Install fittings into cylinder
openings using marks made during the removal process
to properly orientate fittings. Tighten fittings (see Hy-
draulic Fitting Installation in this chapter).
3. Install steering cylinder to machine. When securing
cylinder ball joints to machine:
Greasable style ball joints − tighten the first jam nut
from 65 to 85 ft−lb (88 to 115 N−m), then tighten the
second jam nut to the same specification.
Non−greasable style ball joints − tighten the flextop
lock nut from 85 to 115 ft−lb (115 to 156 N−m).
4. Remove caps and plugs from steering cylinder fit-
tings and hoses. Using labels placed during cylinder re-
moval, properly connect hydraulic lines to steering
cylinder (see Hydraulic Hose and Tube Installation in
this chapter).
5. Secure rear wheel to the machine with four (4) lug
nuts. Lower machine to the ground. Torque wheel lug
nuts in a crossing pattern from 45 to 65 ft−lb (61 to 88
N−m).
6. Make sure hydraulic tank is full. Add correct oil if ne-
cessary.
7. After assembly is completed, operate steering cylin-
der to verify that hydraulic hoses and fittings are not con-
tacted by anything.
