1. Before removing any parts from the hydraulic sys-
tem, park machine on a level surface, set brake, lower
cutting units and stop engine.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components.
2. Label all hose connections for assembly purposes
3. RemovehoseassembliesandO--ringsfromhydrau-
lic fittings at the steering cylinder. Allow hoses to drain
intoasuitablecontainer.
4. Remove lock nut and flatwasher from barrel mount-
ing stud. Remove steering cylinder from barrel stud.
5. Remove two (2) jam nuts andflat washer from cylin-
der rod end at rear wheel castor fork.
6. Remove steering cylinder from traction unit.
7. Note fitting orientation on cylinder for assembly pur-
poses.RemovefittingsandO--ringsfrom cylinderports.
Discard O--rings.
8. Ifrodend(item9)istoberemovedfromcylinderrod,
fullyretractcylinderrodandmeasuredistancefromcen-
ter of rod end to end of cylinder for assembly purposes
(Fig. 74). Record measured distance. Loosen jam nut
andthenremove rodendand jamnut fromcylinderrod.
Installation (Fig. 73)
1. Ifrodend(item9)wasremovedfromcylinderrod,ful-
lyretractcylinder shaftandthread rodend onto shaftso
that distance is as measured during removal process
(Fig. 74). Tighten jam nut to retain rod end.
2. Install hydraulic fittings and O--rings to the steering
cylinder. Make sure that fittings are orientated as noted
during removal.
3. Thoroughly cleantapered surfacesof steering cylin-
der ball joint and cylinder attachment bore on castor
fork.
4. Securecylinderrodendtothecastorforkwithtwo(2)
jam nuts and flat washer. Install first jam nut and torque
from65to85ft--lb(89to115 N--m).Then,whileholding
first jam nut with wrench, tighten second jam nut and
torque from 65 to 85 ft--lb (89 to 115 N--m).
5. Install steering cylinder over barrel mounting stud
and secure with flat washer and lock nut.
6. Connect hydraulichosesand O--rings tothe hydrau-
