HIGH PRESSURE JOINER
CLEAN HOSES AND FITTINGS
HOSE ASSEMBLY INSTRUCTIONS
CAUTION: It is vitally important that no foreign material
AEROQUIP 2755-16 AND FC 136-16
be introduced into the hydraulic system. Do not remove
HOSE AND FITTINGS
any plugs from lines, fittings or hydraulic pump or motor
until ready to make connections. The following steps "a"
and "b" must be complied with before making
connections. Also, it is recommended that when making
hose connections, the male threads be coated with a
heavy oil.
a. Fittings - All fittings, regardless if the ends are
plugged or not, should be inspected for loose
internal particles, thread burrs, etc. Burrs may be
readily seen or felt and removed, however, dust and
dirt may be present inside the fittings. Slush the
fittings back and forth in a deep container of
hydraulic oil. Blow dry with clean air.
b. Hoses - Check hoses and hose end fittings for burrs
and dirt within the hose. Insert a wire of suitable
length thru hose. Attach a piece of lint-free cloth of
suitable thickness to the wire. Dip cloth in hydraulic
oil and draw cloth thru the hose. Fill hose about 2/3
full of clean hydraulic fluid. Rock hose back and
forth several times, empty fluid and blow dry with
clean air.
CABLE CLIPS (Figure 25)
Cable clips are installed on the vibrator control cable
and throttle control cable. The purpose of the clips is to
provide a drag on the cables to hold the settings
required.
The clips are tightened against the cable to a minimum
amount to hold their stroke.
When a cable replacement is made and/or an
adjustment becomes necessary, do not tighten clip down
excessively. Use two clips if necessary.
Below is a sketch of a hose that has been incorrectly
assembled. The inner diameter layer of rubber has
been ruptured, and in many cases the rubber is torn
loose into shreds. This condition will cause hydraulic
line leaking and eventual hydraulic system failure if not
detected and corrected.
Inspect inside of hose fitting assembly for distortion of
the inner diameter. Make sure no foreign material is left
in the hose. Flush with oil and air blow dry before final
line connection.
