DEEP WATER FORDING KIT
The deep water fording kit as installed on the M88A2 HRV permits fording to a maximum depth of 7 feet, 6 inches
(2.286 m). The design of the deep water fording equipment permits the vehicle to be completely operable on land
or in water, providing maximum depth is not exceeded.
Main Engine Exhaust The main engine exhaust system (1) for deep water fording consists of a series of pipes to
provide the proper venting of the exhaust for the right and left banks of the engine. A flexible bellowed--type pipe is
clamped to the main engine exhaust outlet. Utilizing a slip--joint, each pipe is attached to the main engine exhaust
pipe which ducts the exhaust gases through the rear engine deck. To each main exhaust pipe, a 4 1/2--inch
(114.3 mm) diameter pipe which extends above the specified depth, is clamped and sealed. Two clamps, bolted to
the engine deck, are used to hold the system in proper position.
Main Engine Air Inlet The main engine air inlet system (2) provides for the use of outside air for the main engine
while the vehicle is in the water. The system (2) consists of two pipes and two seals, which cover and seal each of
the air intake vents on the top of the vehicle cab.
