PIPE THREAD FITTING TORQUE
Before installing and tightening pipe fittings, clean the
threads with a clean solvent or Loctite cleaner and ap-
ply sealant for all fittings including stainless steel or for
most metal fittings. For high filtration/zero contamination
systems use .
INSTALLATION OF ORFS (O-RING FLAT
FACED) FITTINGS
When installing ORFS fittings thoroughly clean both flat
surfaces of the fittings (1) and lubricate the O-ring (2) with
light oil. Make sure both surfaces are aligned properly.
Torque the fitting to specified torque listed throughout the
repair manual.
NOTICE: If the fitting surfaces are not properly cleaned,
the O-ring will not seal properly. If the fitting surfaces are
not properly aligned, the fittings may be damaged and will
not seal properly.
NOTICE: Always use genuine factory replacement oils
and filters to ensure proper lubrication and filtration of en-
gine and hydraulic system oils.
The use of proper oils, grease, and keeping the hydraulic
system clean will extend machine and component life.
