of the two air cleaners. If the sleeve (2) (figure 17, view B) inside the

gage is green, the air cleaner is working properly and does not need

servicing. If the sleeve (2) inside the gage is red, the air filter element

is clogged and needs to be cleaned or replaced.

For the purpose of this

task, it is assumed that maintenance personnel find that the red sleeve is

showing in both air cleaner restriction gages.

Upon further inspection,

maintenance personnel find that the right side horizontal air intake hose is

bent, preventing the proper flow of air to the cylinders on that side of the

engine.

The following maintenance, adjustment, and repair procedures

describe the maintenance of the air cleaner and the replacement of the right

side air intake hose.

Since the procedure for servicing both air cleaners is

the

same,

the

following step describes the procedure for one air cleaner.

Step 1. Clean away any dirt or mud that is restricting the free flow of air

through the air intake screen (figure 25 on the following page).

WARNING

NBC (nuclear, biological, and chemical) contaminated

filters must be handled using adequate precautions, as

stated in FM 21-40, and must be disposed of by CBR

Step 2. Loosen and pull away four wing nut clamps (1) (refer to figure 17,

view A) from the dust cover (2) and remove the dust cover.

Step 3. Remove the dust cover baffle (3) by removing the wing nut (4) and

pulling the ring (5). Clean the dust cover with a water-damp cloth.
