Engine Compartment: Compartment Inspection

Check the windshield washer reservoir fluid level

Check the air intake restriction indicator with the engine off

Check if air restriction exceeds the maximum allowable value

If air restriction exceeds the maximum value again, replace the air cleaner

Inspect water evacuation components

Inspect the vacuator valve(s) installed on the hood interior and air cleaner

Inspect the rain tray installed at the base of the windshield

Inspect the drain hoses installed on the rain tray

See the following tables for procedures that should be performed monthly, post-trip. Place a check mark in the complete (Comp.) column to indicate a procedure has been performed.:

Walk around the vehicle and inspect brake system components for visible damage. 1. Inspect all visible brake system components for missing fasteners or signs of looseness, such as rust tracks.

NOTICE: If the external breather tube or breather cap is missing or incorrectly installed, road dirt and debris can adversely affect the operation of the brake chamber. Once inside of the chamber, dirt and debris can cause the internal parts of the chamber to deteriorate faster.

2. Inspect the exterior surfaces of brake chambers for damage. Make sure that breather holes are open and free of debris.

NOTE: Do not route air brake lines on top of anything likely to be stepped on.

3. Inspect air brake lines for dents, swelling, kinks, twisting, abrasion, and damage, especially near moving parts.

4. Inspect flex air lines for deterioration or signs of abrasion.

5. Inspect for cracked, worn, or oil-contaminated brake linings and brake drums (or rotors).

Park the vehicle on a level surface, 25 ft (7.6 m) away from, and perpendicular to, a vertical screen or wall. Shut down the engine and set the parking brake. Chock the tires.

Measure the distance from the ground to the height adjusting dot on each headlight (Fig. 23.2, Item A).

On the screen or wall, mark the locations of each headlight bulb center using the distances found in step 2. See Fig. 23.2, Items 2 and 3.

Marks on the wall correctly placed?

Turn on the low-beam headlights.

Check the vertical adjustment of the low beams. The center of each beam projection should fall on or near the marks made during step 3. See Fig. 23.3.

Low-beam headlights correctly adjusted?

Large amounts of mud or ice removed from the underside of the fenders

Springs checked for sagging or broken leaves

Suspension checked for proper functioning of the leveling mechanism

Cabs with air suspensions have properly adjusted height

Hood and hinge assembly checked for damage

Tires inflated to the recommended air pressure

See the following tables for a list of procedures that should be performed daily, before the first trip. Place a check mark in the complete (Comp.) column to indicate a procedure has been performed.:

Suspension and Slack Adjusters:

Walk around the vehicle and visually inspect suspension and slack adjuster components.

1. Inspect the following suspension components for signs of structural damage, cracks, or wear.
