When the fitting is tightened, you can feel when
the fitting is tight to eliminate leakage caused by
under or over torqued fittings. Use petroleum jelly
to hold the O-ring in position until the fittings are
assembled.

Note:
Port seal and nut, washer and O-ring (O-ring
Boss) fittings use the same tightening
torque valve chart [Figure 58].
If a torque wrench cannot be used, use the
following method.
Tighten the nut until it just makes metal to metal
contact, you can feel the resistance.
Tighten the nut with a wrench no more than one
hex flat maximum.
Do not over tighten the port seal fitting.
Note:
If a torque wrench cannot be used, use
the hex flat tightening method as an
approximate guideline.
Note:
Port seal fittings are not recommended in
all applications. Use O-ring boss fittings in
these applications.
Tubelines And Hoses
Replace any tubelines that are bent or flattened.
They will restrict flow, which will slow hydraulic
action and cause heat.
Replace hoses which show signs of wear, damage
or weather cracked rubber.
Always use two wrenches when loosening and
tightening hose or tubeline fittings.
