(14) = Adjust tire pressures as indicated on the Gross
Vehicle Weight (GVW) Rating label for optimum tire life.
See Tires on page 5-74 for further details. Check
tires for excessive or abnormal wear or damage. Also
check for damaged wheels. Replace wheels and/or tires
as needed.
(15) = Check spring-to-axle U-bolts and shackle bolts
for proper torque. See the service manual for torque
sequence and specifications. When parts are replaced,
the torque must be checked and adjusted more often
during the first 6,000 miles (10 000 km). Check torque at
500 miles (800 km) and 2,000 miles (3 000 km) after
first use of parts.
(16) = Check complete exhaust system and cab areas
near the exhaust system for broken, damaged,
missing, or out-of-position parts. Also inspect for open
seams, holes, loose connections, or other conditions
which could let exhaust fumes seep into the driver
compartment. Needed repairs should be made at once.
To help maintain system integrity, replace exhaust
pipes whenever a new muffler is put on.
(17) = Check all gasoline engine drive belts for cracks,
fraying, and wear. Replace as needed.
(18) = Adjust valve lash. Incorrect valve clearance will
result in increased engine noise and reduced engine
output.
(19) = With the engine off and below normal operating
temperature, check to see that the thermostatically
controlled engine cooling fan can be rotated by hand on
viscous-operated drives. Replace as needed.
(20) = Check shields and underhood insulation for
damage or looseness. Adjust or replace as needed.
(21) = Inspect parking brake drum and linings for wear
or cracks and check linkage and adjustment.
(22) = Wheel bearing service:
•
Grease type — Clean, inspect, and lubricate with
the proper wheel bearing grease at designated
intervals or when hubs are removed. See
Part C: Recommended Fluids and Lubricants on
page 6-33.
•
Oil-filled type — Some wheel bearings are
lubricated by axle lubricant. When you have oil-filled
hubs, use lubricant identical to that used in the
axle. Lubricant change intervals are the same for
front and rear axles. However, you must maintain
the proper oil level between change intervals.
See Front Wheel Bearings with Oil-Filled Hubs on
page 5-73 and Part C: Recommended Fluids
and Lubricants on page 6-33.
