THEORY OF OPERATION (Contd)

SPECIAL PURPOSE BODIES (Contd)

M50A3 Water Tank System Operation: Water can be dispensed either by gravity or under pressure

by operating a delivery pump driven off the transfer case PTO. When operating in temperatures below

32 F (0 C), engine exhaust heat is diverted under water tanks to prevent water from freezing.

A WATER DISCHARGE HOSES Used to deliver water from tank compartments.

B STRAP Used to secure manhole cover during artic operation when heaters are installed in tank

openings.

C WATER LEVEL GAUGE Dipped into tank compartments to measure water levels.

D WATER SUCTION STRAINER Attached to water suction hose to prevent foreign matter from

entering tank.

E YCOUPLING Attached to the line discharge/suction valve to facilitate delivery of two streams of

water at the same time.

F WATER SUCTION HOSES Used to fill tank compartments when gravity fill cannot be used.

G GRAVITY DELIVERY LINE SUCTION VALVE Turning handle to the left allows water flow

through gravity delivery line.

H PUMP DELIVERY LINE SUCTION VALVE Turning handle to the left allows water flow through

pump delivery line.

COMPARTMENT VALVE LEVERS When pulled back, opens discharge valves which control flow

of water from tank compartments.

J WATER DISPENSER NOZZLE Controls flow of water at the point of delivery.
