Hydraulic System - Lines - New Holland B95CTC Operator's Manual

Hydraulic system - lines

Check the hydraulic system lines for possible leaks.
Repair all hydraulic oil leaks promptly to avoid loss of oil
and possible damage and dirt entry into the system. When
checking for hydraulic leaks, start and operate the engine
at 1200-1500 RPM.
Remove and install new hoses immediately, if they are se-
verely damaged by a cut or scrape, swollen at the fittings,
or leaking.
ATTENTION: If leaks are detected, stop the engine, re-
lease the hydraulic system pressure and clear the problem.
Do not unscrew hoses or fittings without releasing the hy-
draulic system pressure first.
If a hydraulic hose or tube is replaced, the following proce-
dure should be observed.
Loosen the fittings (1) and remove the hose or tube, then
remove and discard the O-ring seal (2).
Immerse the new O-ring into clean hydraulic oil before as-
sembly.
Install the new O-ring (2) into the fitting (1) and if necessary,
retain in position using petroleum jelly. Assemble the new
hose or tube and tighten the fitting finger-tight, while hold-
ing the tube or hose to prevent it from turning. The tube's
or hose's turning could damage the O-ring.
Using two suitable wrenches, tighten the fittings to specifi-
cation.
NOTICE: when replacing or assembling a pipe or hose,
make sure that all elements are perfectly clean and free
from any trace of dirt. Failure to ensure absolute cleanli-
ness will result in the hose / pipe leaking after installation
or possible damage to other hydraulic system components.
To ensure a leak free joint is obtained, it is important that
the fittings are not overtorqued or undertorqued.
When replacing a hose, it is necessary to bleed air from the
system. For this purpose, let the engine run at 1200–1500
RPM, contemporarily actuating the loader and backhoe at-
tachment controls for 15 min or until air is bled from the
system.
