(10) = Check clutch pedal for free travel. Press pedal
by hand until resistance is felt. Free travel should be
maintained at 1.5 to 2 inches (38 to 51 mm) measured
at the clutch pedal pad. Make checks at 3,000 miles
(5 000 km) and 6,000 miles (10 000 km) and then
every 6,000 miles (10 000 km) thereafter.
(11) = Inspect rear axle air shift motor for fluid leaks.
Remove plug to check fluid level. Inspect air lines and
-
hoses for proper hook up, binding, leaks, etc. Inspect at
3,000 miles (5 000 km) and 24,000 miles (40 000 km)
and then every 24,000 miles (40 000 km) thereafter.
(12) = Chassis Lubrication Service: Lubricate all grease
fittings in front suspension, front axle, steering linkage
and steering gear at output shaft sleeve bearing.
DO NOT lubricate kingpin bushings or steering gear
output shaft sleeve bearing with air pressure equipment;
instead, use a hand grease gun to ensure complete
purge and eliminate sealer cap distortion. Lubricate
transmission and shift linkage, hood latches and
hood hinges, parking brake lever pivot, clevis pins
and linkage, disc brake caliper rails, clutch linkage and
release bearing (if equipped), propeller shaft slip joint,
universal joint, brake camshaft bracket, slack adjusters,
pedal shaft, clutch cross shaft and clutch pedal springs.
Lubricate suspension, axle and steering linkage more
often when operating under dusty or muddy conditions
-
and in excessive off road use.

(13) = Check steering system:
D
Look for damaged, loose or missing parts.
Also look for parts showing signs of wear or lack
of lubrication. Replace parts as needed. Also check
steering gear mounting bolts, pitman arm nut, gear
housing upper cover and side cover attaching bolts,
steering column mounting bolts and cardan joint
clamp bolts; tighten if necessary. (See service manual.)
D
Inspect power steering hoses, tubes and fittings for
leaks. Hoses and lines must not be twisted, kinked or
tightly bent. Make sure clips, clamps, supporting
tubes and hoses are in place and properly secured.
D
Check steering gear for leakage around pitman
shaft and housing. If leakage is evident (lubricant
oozing out, not just oily film), leak should be
corrected immediately.
(14) = Check front and rear suspension. Look for
damaged, loose or missing parts or parts showing signs
of wear or lack of lubrication. Replace parts as needed.
(15) = Adjust tire pressures as indicated on the
Certification/Tire label for optimum tire life. See "Tires"
in the Index for further details. Check tires for excessive
or abnormal wear or damage. Also check for damaged
wheels. Replace wheels and/or tires as needed.
