ELECTRICAL GROUND POINTS - CONTINUED
WARNING
Although master battery switch must be on and battery ground cable connected in order to test electrical cir-
cuit voltage, turn off master battery switch or disconnect battery ground cable before performing resistance
tests or replacing parts. This will prevent shock to personnel, and damage to parts and equipment.
a.
Remove hardware connecting ground cable terminal lug to ground point.
b.
Clean mounting hardware, ground cable terminal lugs, and ground point with detergent (Item 11, WP 0235 00) and
scrub brush.
c.
Remove any rust with wire brush and crocus cloth.
d.
Look for cracks, loose terminal lugs, and stripped threads. Replace any defective parts.
e.
Install hardware connecting ground cable terminal lug to ground point. Ensure that all hardware is tight.
LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing fuel, oil, and coolant lines, perform the fol-
lowing steps:
a.
Clean fittings and surrounding area before disconnecting lines.
b.
Cover, cap, plug or tape lines and ports after disconnecting lines. When these are not available, use hand-carved
wooden plugs, clean rags (Item 28, WP 0235 00), duct tape (Item 33, WP 0235 00) or other similar materials to pre-
vent dirt from entering system.
c.
Ensure that new and used parts are clean before installing.
d.
Wait to remove cover, cap, plug or tape from lines and ports until just before installing lines.

Used tube assemblies in good condition can be installed to their original location without leaking.
3.
Assemble new tubes, compression sleeves, and inverted nuts as follows:
a.
Slide inverted nut onto end of tube.
b.
Slide compression sleeve onto end of tube.
c.
Repeat previous two steps for other end of tube as required.
