locknut.
Install the handwheel on the valve stem and fasten the screw to
hold it in place. Connect both fuel hoses to the elbows at the back of the
valve. Open the fuel supply line at the base of the fuel tank and check for
leaks. If the installation is leaktight, it is satisfactory.
Starting procedure plate and nameplates. Remove the drivescrews that fasten
the plate to the control panel. Remove the plate. Attach the new plate on
the control panel with drivescrews.
Valve handles and handwheels. Remove the handwheels of valves No. 1, 2 and
3 by removing the pin that connects the handwheel to the valve stem. Pull
the handwheel off the valve stem.
Remove the handles of the pump-drain
valve and the prime-detergent tank valve by removing the nut washer, and
handle from the extension rods. Installation is the reverse of removal.
Battery. A battery that will no longer hold a charge will be replaced. Use
the following removal and installation procedures to change an unserviceable
battery.
Removal.
Remove the lower left front panel by turning the turnlock
fasteners one-quarter turn.
Remove the panel.
Disconnect the positive
cable from the battery POS terminal. Disconnect the ground strap (negative)
from the battery NEG terminal. Remove the self-locking nut and washer from
the two battery-retaining hook bolts and remove the battery bracket from the
top of the battery. Use the plastic rope on the battery to remove it from
the pump unit.
Remove the battery pad from the pump unit.
Clean the
battery, bracket hook bolts, and the pad, if necessary, by using baking soda
in water and a brush. Rinse with clear water. Remove the battery cables
and clean them. Replace the battery cables, if necessary.
Installation.
Position the battery pad through the two battery-retaining
hook bolts. Position the POS terminal end of the battery nearest the pump.
Position the battery bracket and retaining hook bolts on top of the battery.
Install the washers and self-locking nuts on the two retaining hook bolts.
Connect the battery negative cable to the battery (NEG) terminal. Connect
the positive cable to the battery (POS) terminal. Coat terminals with GAA
to prevent corrosion and block moisture; then tighten the terminal
connections. Position the lower left front panel on the pump unit. Fasten
the panel by turning the turnlock fasteners one-quarter turn.
Fuel Tank. Organizational maintenance repairs to the fuel tank are limited
to repainting, replacing the fuel cap, fuel hose, sediment bowl, and the
sponge-rubber pad that is cemented to the top of the fuel tank. The label
on the bonding adhesive contains instructions for bonding the sponge-rubber
pad to the fuel tank. The pad prevents the cover of the pump-unit assembly
from striking the fuel tank.
