AirMax Plus
— Prepare the AirMax breather for
installation by removing the two smaller red plastic
plugs from the bottom air vents located 180°F apart .
Also, remove the large red plastic plug from the
breather mounting threads . Thread the breather into
the pipe tee of the Reliability Package as shown in
Figure 1 . Hand-tighten only to seal o-ring against pipe
tee . For detailed breather installation and maintenance
instructions, refer to the literature included with the
AirMax Plus breather (GR3-002) .
5 .
Lifting
— The drive can be lifted by using either
the torque arm anchor brackets or a sling wrapped
around the seal housing and input shaft . Lift and
mount the drive by following the drive installation and
lifting instructions provide in Section 1 (page 6) of this
Owner’s Manual . If the torque arm bracket is used to
lift the unit, confirm that there isn’t any oil in the drive
before lifting
CAUTION
: To prevent damage to the hydraulic tubing,
it should NOT be installed until after the drive has been
lifted and mounted into position. Prevent debris from
entering the drive by covering the Lenz fittings of the
subassemblies, until the hydraulic tubing can be installed.
6 .
Hydraulic Tubing
— Install the hydraulic tubing by
following the steps outlined below:
1 . Remove the nut and tapered split ring from the two
Lenz fittings .
2 . Slide the nut and the tapered split ring onto the ends
of the hydraulic tubing . The large end of the tapered
ring should face the fitting .
3 . Apply oil to the O-ring .
4 . Insert the ends of the hydraulic tubing simultaneously
into the appropriate Lenz fittings .Continue to push the
tubing into the Lenz fittings until the tube ends are
past each o-ring for proper sealing .
NOTE
: The hydraulic tubing may have to be bent
slightly to install it properly into the Lenz fittings thus
ensuring the tubing extends past the o-rings in the
fittings .
5 . Once the hydraulic tube is positioned properly, slide
the tapered spit rings up to the Lenz fittings .
6 . Tighten the nut hand tight . Then with a wrench tighten
one turn or until the rear of the tapered ring is flush
with the nut .
7 .
Oil Fill
— Remove the oil fill pipe plug from location
#3 as shown in Figure 2 . Using a funnel with a flexible
spout, fill the gearbox with an approved lubricant (refer
to Page 22 for Lubrication Recommendations; DO
NOT USE GMAX 6000 or other types of polyalkylene
glycol (PAG) lubricants which are not compatible with
the polycarbonate sight glass) . Once the oil level
reaches the bottom of the fill hole, wait a minimum of 5
minutes for the oil to reach the oil level sight glass . Add
additional oil to the gearbox and repeat the process
until the oil level in the gearbox and sight glass are
constant and the excess runs out . It is recommended to
mark the sight glass with this final oil level .
The oil level sight glass is intended to be used when
the gearbox is not running; in the static condition .
Therefore, the sight glass contains a label that indicates
a static oil level .
(oil levels tend to fluctuate based on oil
churning and are dependent on speed and direction
of rotation; for continuous direction, and continuous
speed applications it is recommended that the oil level
sight glass be marked once steady state operating
conditions have been reached)
.
Prepare the oil fill pipe plug for installation by applying
Loctite joint compound #1534294 to the threads .
Reinstall the elbow subassembly into the Quadrive
housing at location #3 as shown in Figure 2 .
MAINTENANCE INSTRUCTIONS
AirMax Breather
— Falk AirMax Plus breathers have visual
indication when they need to be changed . As the breather
functions, the silica gel material changes color from blue
to pink as it absorbs moisture . When all the material has
turned pink in color, it is time to replace the breather .
Breather life is dependent on operating conditions
and ambient conditions (humidity) . Breather should be
changed every twelve (12) months regardless of color
Oil Sampling
— The oil sampling port that is
included allows users to easily draw oil samples for
lubrication analysis . Refer to the Oil Analysis Report
section in Appendix A of this document for detailed
recommendations on oil content . The oil sample port has
a screw on cover that needs to be unscrewed in order to
access the valve to the sampling port . The valve can then
be actuated by screwing on the threaded oil sample port
adapter included in our Oil Sample Kit (sold separately;
see Table 2) . The sampling bottle is composed of PET
(polyethylene terephthalate) which is compatible with
most industrial lubricants; however, user should confirm
compatibility prior to use . It should be noted that the
cleanliness of the bottle can greatly affect the results of an
oil sample analysis; therefore user is cautioned to use care
to avoid contamination of the sample .
The oil sample should be taken shortly after the unit has
been shut down to ensure the oil is properly mixed . It is
important to initially purge some oil from the oil sampling
port and discard this purge, prior to collecting the sample .
Be sure to check the oil level in the drive after the sample
has been collected (additional oil may need to be added to
ensure proper level) .

Elbow Subassembly
— Prepare the elbow
subassembly for installation by applying Loctite joint
compound #1534294 to the male threads as shown
in figure 4 . Install the elbow subassembly into the
Quadrive housing at location #2 as shown in Figure 2 .
The galvanized elbow should be used to thread the
subassembly hand tight . Using a pipe wrench, turn the
galvanized elbow an additional 2-3 turns so that it is oil
tight . The elbow should be parallel to the output shaft
when finished as shown in Figure 1 .
