For a metal tube to hose installation, install
the tube and tighten all bolts finger tight.
Tighten the bolts at the rigid end.
Install the hose and tighten all bolts finger
tight.
Put the hose in a position so that it does not
make contact with the machine or another
hose.
Tighten the bolts on both connections.
Start the engine.
Move the implement control levers to all
positions.
Look at the hose during movement of the
implement. Make sure hose is not in contact
with the machine or other hoses.
Shut off the engine.
If necessary, put the hose in a new position
where it will not make contact when the
implement is moved.
ASSEMBLY OF FITTINGS WITH
STRAIGHT THREADS AND O-RING SEALS
This type of fitting is used in many applications.
The tube end of the fitting will be different in
design so that it can be used in many different
applications. However, the installation procedure
of the fitting is the same. If the tube end of the
fitting body is the same as in the illustration (either
an elbow or a straight body) it will be necessary to
assemble the sleeve on the tube before connecting
the tube to the end.
ELBOW BODY ASSEMBLY
1. End of fitting body (connects to tube). 2. Fitting body.
3. Locknut.
4. Backup washer. 5. O-ring seal. 6. End of
fitting that goes into other part.
1.
2.
Put locknut (3), backup washer (4) and O-ring
seal (5) as far back on fitting body (2) as
possible. Hold these components in this posi-
tion. Turn the fitting into the part it is used
on, until backup washer (4) just makes contact
with the face of the part it is used on.
To put the fitting assembly in its correct
position turn the fitting body (2) out (coun-
terclockwise) a maximum of 359°. Tighten
locknut (3) finger tight.
NOTE: If the fitting is a connector (straight
fitting) the hex on the body takes the place of the
locknut. To install this type fitting tighten the hex
against the face of the part it goes into.
TORQUES FOR FLARED
AND O-RING FITTINGS
The torques shown in the chart that follows are
to be used on the nut part of 37° Flared, 45°
Flared and Inverted Flared fittings (when used
with steel tubing), O-ring plugs, O-ring fittings and
swivel nuts when used in applications to 3000 psi
(20700 kPa).
