and wheel seals for leaks and
loose mounting hardware or
broken items. Check lube level,
if equipped with sight glass.
4. Wheel and Lug Nuts: Check for
damaged or bent wheels.
Check to see that all the lug
nuts are present and not loose.
Look for rust trails around nuts.
Ensure that no cracks or
damage are present at the
wheel mount holes.
5. Fuel Tank(s): Check to see that
the fuel tank and cap are
secured, and make sure there
is no damage or leaks at the
tank or fuel lines.
6. Brake Caliper and Hoses:
Check for cracked, worn,
or frayed hoses, and for secure
couplings. Check for broken,
loose, or missing parts.
7. Tires: Check the tread depth
and tire inflation. Note if the
tread is evenly worn. Minimum
tread depth is 3 mm (4/32 in)
on all tires. Look for cuts or
other damage to the tread
sidewalls. See if the valve caps
and stems are missing, broken,
or damaged. Check dual
spacing to ensure that dual
wheels are evenly separated,
and that the tires are not
touching one another.
8. Torque Rods and Shock
Absorbers: Check to see that
the torque rods are not
cracked, broken, or missing.
Check shock absorbers for
cracks or leaks. There should
be no missing or broken
mounting bolts or worn
bushings.
9. Brake Pads and Rotor: With
brakes released, check to see
that the brake linings (where
visible) are not worn
excessively thin, less than
6 mm (0.25 in),
or contaminated by lubricant.
Where visible, check the disc
brake caliper wear indicator to
see that the brake pads/rotor
are not worn excessively.
Check electrical wiring for proper
security, damage, and chafing.
