After Repairing or Replacing the Components (continued)
and
Installing the Hydraulic Fittings (SAE Straight Thread
O-Ring Fitting into the Component Port) (page 4–7)
.
5. After you complete the repairs, check the control linkages or cables for
proper adjustment, binding, or broken parts.
6. After you disconnect or replace any hydraulic components, operate the
machine functions slowly until the air is out of the system; refer to
the Hydraulic System (page 4–61)
.
7. Check for hydraulic-fluid leaks. Shut off the engine and repair leaks if
necessary.
Checking the Hydraulic Lines and Hoses
WARNING
Hydraulic fluid escaping under pressure can penetrate skin and
cause injury.
•
Ensure that all hydraulic-fluid hoses and lines are in good
condition and all hydraulic connections and fittings are tight
before applying pressure to the hydraulic system.
•
Keep your body and hands away from pinhole leaks or nozzles
that eject high-pressure hydraulic fluid.
•
Use a piece of cardboard or paper to find hydraulic leaks.
•
Release all pressure in the hydraulic system before performing
any work on the system.
•
Seek immediate medical attention if hydraulic fluid is injected
into your skin.
IMPORTANT
Check the hydraulic lines and hoses daily for leaks, kinked lines,
loose mounting supports, wear, loose fittings, weather deterioration,
and chemical deterioration. Repair the damaged hydraulic equipment
before operating the machine.
Priming the Hydraulic Pumps
When the hydraulic system is flushed, the hydraulic system is charged, or the
hydraulic components are installed, it is important to properly prime the hydraulic
pumps. The hydraulic pump priming ensures that the gear pump and piston
(traction) pump have sufficient fluid during initial start-up and running. The
pumps can be primed by using a remote starter switch (refer to
(page 4–23)
) to crank the engine which allows the pumps to prime.
Use the following procedure to prime the hydraulic pumps:
1. Ensure that the key switch is in the O
FF
position and the key is removed
from the key switch.
2. Check the hydraulic-fluid level in the hydraulic reservoir and add correct
quantity of fluid if necessary; refer to the
Traction Unit Operator’s Manual
.
