Replace light bulbs or sealed beam units that are
not working.
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.
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.
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.
Inspect the air lines, as follows:
Pretrip Inspection and Daily Maintenance
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.
35.2 Check for kinks, dents, or swelling of the
hoses. If a hose is damaged, replace it with
the same size and type.
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.
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.
