Removal (Fig. 61)
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine. Remove key from the ignition switch.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components.
2. Label all hydraulic connections and electrical con-
nections for assembly purposes.
3. Disconnect wire harness connectors from manifold
solenoid coils and backlap switch.
IMPORTANT: Before disconnecting any hydraulic
hoses from the hydraulic fittings, make sure each
hose is labeled to ensure it is connected to the cor-
rect manifold fitting/port.
4. DisconnecthoseassembliesandtheirrespectiveO--
rings from hydraulic fittings. Allow hoses to drain into a
suitable container.
5. Removetwo(2)capscrews(item12)thatsecurethe
hydraulic manifold to the frame. Remove manifold as-
sembly from the machine.
IMPORTANT: Before disconnecting any hydraulic
fittings from the hydraulic manifold block, make
sure the position of each fitting is observed and
matchmarked to ensure it is oriented p roperly on
the manifold.
6. If hydraulic fittings are to be removed from manifold,
mark fitting orientation to allow correct assembly. Re-
move hydraulic fittings and O--rings from manifold. Dis-
card removed O--rings.
Installation (Fig. 61)
1. If fittings were removed from manifold, lubricate and
placenew O--ringsontofittings.Installfittingsintomani-
fold openings making sure that fitting orientation is as
notedduringremoval.Tightenfittings(seeHydraulicFit-
tingIns tallationintheGeneralInformationsectionofthis
chapter).
2. Position manifold assembly to the support frame.
Secure assembly to the frame with two (2) cap screws
(item 12).
3. Using labels placed during manifold removal, lubri-
catenew O--rings and connect hydraulic hoses tomani-
fold.Tightenhoseconnections(seeHydraulicHoseand
Tube Installation in the General Information section of
this chapter).
4. Connect wire harness connectors to manifold sole-
noid coils and backlap switch.
5. Make sure that hydraulic tank is at correct level.
6. Startmachine.Runmachineatidlefor3to5minutes
