Pretrip Inspection and Daily Maintenance Replace light bulbs or sealed beam units that are not working. 35.1 Check the clearance between the hoses, exhaust manifold, and turbocharger, or other hot spots. Excessive heat will cause the ma- terial in the hoses to deteriorate rapidly or become brittle. Provide at least six inches (150 mm) of clearance. More clearance is recommended, especially if the hose is lo- cated above the heat source. Be sure all reflectors and lenses on the vehicle are in good condition and are clean. Replace any bro- ken reflectors or lenses. Turn the lights off. 34. Check the outer surfaces of the cab for visible sur- face breaks and damage. 35.
Inspect the air brake components including the brake chamber pushrods, air reservoirs, and air lines. 35.2 Check for kinks, dents, or swelling of the hoses. If a hose is damaged, replace it with the same size and type. Look for worn pins on brake chamber pushrods and missing or damaged cotter pins on the brake cham- ber pushrod pins. Replace worn pins and install new cotter pins if necessary. 35.3 Do not route the hose on top of anything likely to be stepped on or walked on. 35.4 Check for damage to hoses located near moving parts, such as drivelines, trailer bod- ies, kingpins, suspensions, and axles. If the moving parts are catching or pinching the lines, correct as needed.
Check for rusted connections, missing snap rings, and damaged camshaft grease seals. Repair or replace damaged or missing parts. Check the air reservoir band fasteners. Make sure the outside surfaces of the reservoirs are painted to prevent corrosion damage. Inspect the reservoir surfaces for damage, such as cracks and dents. Replace corroded or damaged reservoirs with new ones. Do not repair damaged reservoirs. Old or used reser- voirs are not acceptable as replacements. If a res- ervoir requires replacement, see Group 42 of the Cargo Workshop Manual for instructions. 35.5 Check for hose damage caused by abrasion. If a hose is abraded, replace it.
Check for the cause of abrasion, such as loose or damaged hose clamps. Repair or replace the clamps as needed. Inspect the air lines, as follows: 9.16
