7. Move behind the rear of the front wheel, inspect
for leaks at hub or brakes or any unusual condi-
tions. Inspect suspension hardware to be sure it
is all in place. Inspect live end of steering cylinder
for proper greasing, and for security of all parts.
Inspect for any hydraulic leaks.
8. Inspect sight glass on hydraulic tank. With engine
stopped and body down, hydraulic fluid must be
visible in lower sight glass.
9. Move on around the hydraulic tank and in front of
the rear dual tires, inspect the hoist cylinder for
any damage and leaks, also that lower guard is
in place. Inspect both upper and lower hoist cyl-
inder pins for security, and for proper greasing.
10. Before leaving this position, look under the lower
edge of the chassis to be sure the flexible duct
that carries the air from the main blower to the
final drive housing is in good condition with no
holes or breakage. Also look up at the main
hydraulic pumps to see that there is no leakage
or any other unusual condition with pumps or
pump drive shafts.
11. Move on around the dual tires, check to see that
all nuts/studs are in place and tight. Inspect wheel
for any leakage that would indicate brake leak-
age, or wheel motor leakage.
Check dual tires for cuts, damage or “bubbles”
and that inflation appears to be correct. If truck
has been run on a “flat”, the tire must be cooled
before parking truck inside. Inspect for any
rocks that might be lodged between dual tires,
and that rock ejector is in good condition and
straight so that it can not damage a tire.
12. Inspect left rear suspension for damage and for
correct rod exposure, and that there are no leaks.
See that covers over the chromed piston rod are
in good condition and inspect for proper greasing.
13. Open rear hatch cover. Inspect for leaks around
the parking brakes. Inspect condition of cooling
air exhaust ductwork to be certain that it is intact
and that there are no obstructions.
14. While standing in front of rear hatch, look up to
see that rear lights are in good condition, along
with dual back up horns. Look up at panhard rod
to see that it is getting proper greasing. Also look
at both body hinge pins for greasing and any
abnormal condition. Check hoist limit switch and
clear any mud/debris from contacts.
15. Perform the same inspection on the right rear
suspension as done on the left.
16. Move on around the right dual tires, inspect be-
tween the tires for rocks, and for condition of the
rock ejector, inspect the tires for cuts or damage,
and for correct inflation.
17. Perform the same inspection for wheel nuts/studs
and wheel leaks that was done on the left hand
dual wheels.
18. Move in front of right dual tires, and inspect the
hoist cylinder the same as was done on the left
side.
Check security and condition of body-up limit
switch. Remove any mud/dirt accumulation from
switch.
19. Move on around the fuel tank, inspect the fuel
quantity gauge, (this should agree with what will
show on the gauge in the cab). Inspect the attach-
ing hardware for the fuel tank at the upper sad-
dles, and then at the lower back of the tank for the
security and condition of the mounts. Check hoist
filters for leaks.
20. Move in behind the right front wheel, and inspect
the steering cylinder, suspension attaching hard-
ware and suspension extension, as well as greas-
ing and attaching hardware for the steering
cylinder. Inspect the hub and brakes for leaks and
any unusual condition. Be sure the suspension
protective boot is in good condition.
21. Move out and around the right front wheel, inspect
that all nuts/studs are in place and tight.
22. Move in behind the front of the right front wheel,
check hub and brakes for leaks and any unusual
condition. Inspect steering cylinder for security
and for proper greasing. Inspect the engine com-
partment for any leaks and unusual condition.
Inspect the fan guard, and belts also for any rags
or debris behind radiator. Turn work light off, if
used, and secure the ladder up and latched.
23. Inspect auto lube system. See Lincoln Auto Lube
in Section “M”, for specific details concerning
auto lube system.
24. Move on around to the right front of the truck, drop
the air cleaner pans to remove dirt, latch up and
secure. Inspect battery box cover for damage and
be sure it is in place and secure.
25. As you move in front of the radiator, inspect for
any debris that might be stuck in front of the
radiator and remove it. Check for any coolant
leaks. Inspect all head and fog lights.
