This task covers:
Trailer parked on level ground, brakes engaged
and wheels chocked.
Tool kit, mechanics general,
Gooseneck must be securely supported during this procedure and resting
on a firm foundation. Severe injury or death to personnel may occur if
gooseneck is unstable or tips.
High pressure hydraulics [oil under 2450 psi (16,893 kPa)] used to operate
this equipment can pierce body tissue and cause severe injury to personnel.
Never disconnect any hydraulic line or fitting without first dropping
pressure to zero.
Wear safety goggles when performing leakage tests on valves. Failure to
do so may result in serious eye injury due to high pressure oil.
Hydraulic lines can be replaced or repaired, depending on the length
of the damaged section. If damaged line is short, replace it. If damaged
line is long, repair it.
for general gooseneck hydraulic line maintenance instructions.
Hydraulic lines and fittings are not ordinarily removed unless they need to be replaced. Badly
damaged hydraulic lines or fittings must be replaced. Hydraulic lines and fittings must be tightly
attached and connected. See gooseneck hydraulic diagram for additional information.
