13.3.2 FLEXIBLE HOSE REMOVAL
Where equipped, cut the safety wire to allow the fire sleeve to be drawn back along the hose to allow
access to the hose clamp.
Loosen the hose clamp.
Remove the hose from the hose fitting.
Note that oil cooler lines, by design, often become bonded or “stuck” to the hose barb. This makes it
impossible, in most cases, to remove these hoses without cutting them.
13.3.3 INSPECTION
Examine the exterior of hoses for evidence of leakage or wetness.
Feel hoses to assess the hardness of the hose. Excessively hard hoses must be replaced as
they are likely to be subject to cracking.
Replace any doubtful hoses.
13.3.4 FLEXIBLE HOSE INSTALLATION
Hoses should not be twisted on installation.
Provide as large a bend radius as possible.
Hoses should have a minimum of 12mm clearance from other hoses or surrounding objects or be
tie-clamped to them.
Where fire-sleeve is used ensure it is fitted per Figure 133.
NOTE: Rubber hoses will take a permanent set during extended use in service. Straightening a
hose with a bend having a permanent set will result in hose cracking. Care should be taken
during removal so that hose is not bent excessively, and during reinstallation to assure hose is
returned to its original position. Excessively hard hoses must be discarded.
