SECTION II INSTALLATION OF HDC PRIMARY MANIFOLD ASSEMBLY,
MANUAL SHUT–OFF VALVE V23, AND LEFT MAIN MANIFOLD PRESSURE
TRANSDUCER T7 -- CONTINUED
3--7
INITIAL INTERCONNECTION AND ALIGNMENT OF HDC PRIMARY MANIFOLD
ASSEMBLY AND DIRECTIONAL CONTROL VALVE (DCV) BANK -- CONTINUED
e.
Install previously removed rigid tube line, 13211E9564, (Figure 3--24 (2)) between upper end of port tube
tee on port 17R (Figure 3--25) of right suspension raise/lower control valve on DCV bank and port 17R
(Figure 3--25) on suspension valve. If necessary, carefully adjust physical alignment of DCV bank and
HDC primary manifold assembly.
f.
While ensuring that tee connectors attached to DCV bank valves remain perpendicular to DCV bank,
tighten attaching hardware that secures DCV bank and HDC primary manifold assembly to mounting
weldment and supporting members in the bowl.
g.
Install coils on solenoid valves V11 (1) and V15 (2) on HDC primary manifold assembly, 12496943, (3).
Refer to Figure 3--10 it necessary.
h.
Install previously removed hydraulic hose on port C1 (winch pay out) on DCV bank winch control valve.
NOTE
The other end of the hose installed in step i below connects to a circuit 20 tee connector
as shown in Figure 3--26. It may be necessary to re--orient the circuit 20 tee connector
45
_
to the bottom of the bowl as shown in Figure 3--26.
i.
Install previously removed hydraulic hose on port 20 (lower apron) on DCV bank apron control valve.
j.
Install previously removed hydraulic hose, 13214E2457--9, (originally connected directly to DCV bank
port 22 (Figure 3--25) (ejector retract) to 90
_
adapter (Figure 3--24 (11)) attached to bottom of ball valve
V23 on DCV bank port 22.
k.
Install diagonal hydraulic tube, 12496939, (Figure 3--24 (6)) between primary manifold assembly port 3R
(Figure 3--25) and DCV bank right front wheel raise (suspension) line 3R.
l.
Install small hydraulic tube, 12496940, (Figure 3--24 (9)) between primary manifold assembly port 19
(Figure 3--25) and DCV bank apron valve line 19.
m. Install small hydraulic tube, 12496940, (Figure 3--24 (5)) between primary manifold assembly port C2
(Figure 3--25) and DCV bank winch pay--in line C2.
n.
Install small diagonal hydraulic tube, 12496963, (Figure 3--24 (7)), between primary manifold assembly
port 3L (Figure 3--25) and DCV bank left front wheel raise (suspension) line 3L.
o.
Install large hydraulic tube, 12496941, (Figure 3--24 (10)) between primary manifold assembly port 21
(Figure 3--25) and DCV bank valve ejector extend control valve line 21.
p.
Ensure that previously removed hydraulic hose, 13214E9566, (Figure 3--24 (3)) is reconnected as shown
between pipe tee on right side of suspension (sprung/unsprung) valve and top of right suspension
raise/lower control valve on DCV bank.
