Application
The SAND TRAK Model ST1-075A la was
developed to use as an accessory attachment to
expand the versatility of the Military Small
Emplacement Excavator (SEE Tractor)
The attachment is used instead of the SEE
Tractors normal 3/4 yard loader bucket. The
sandbagger attachment, following initial installation
of the quick disconnects kits onto the excavator
attachment, is easily installed and/or removed
within fifteen minutes.
The sandbagger attachment may be maintained on
the host vehicle for movement of granular
materials or for filling sandbags.
The sandbagger is designed for use with “A”grade
(3/4 inch minus) sand and gravel or smaller. The
sandbagger was not designed for material with a
high clay content or large pieces of frozen
material.
The sandbagger screen will not permit gravel or
rocks through the screen in excess of 1-3/4 inch in
size. Material having excessive amounts of 1-3/4
inch material clay or debris will cause the screen to
clog rapidly, requiring that the sandbagger screens
be cleaned. (See section on cleaning under
Starting and Operating).
Filling sandbags requires one person to hold bags
for filling and a second person to poerate the host
vehicle’s excavator boom or bucket function
control. A mirror is utilized by the operator to see
the person filling bags for start and stop signals.

ST1-075A Ia 12/98
Figure 3 OM0260
Hydraulic Installation
The sandbagger utilizes the SEE TRactor
excavator boom or bucket tilt circuit for hydraulic
power and control.
Hudraulic pressure to the excavator boom function
originates at the boom function control valve
located at the excavator attachment control
station. The quick disconnect kit is installed as
shown in Figure 3. Two hoses (connection hoses)
are utilized from the quick disconnects located on
each side of the excavator boom, routed to quick
disconnects (2) located on the upper right back
side of the sandbagger attachment (Figure 3).
The sandbagger is supplied with quick disconnects
on the attachment and on both ends of the
connection hoses.
The quick disconnects are arranged so that auger
rotation, clockwise when looking at the end of the
auger, (Figure 4) is correct when control lever is
pushed away from operator.
A quick disconnect kit for easy installation and
removal of the sandbagger attachment is supplied
for installation on the host vehicle. This kit
contrains 2 sets of quick disconnects with adapter
fittings (Figure 5). See parts manual for kit part
number. Figure 4

Starting And Operating
Review all safety practices as defined in this
manual. Read the host vehicle operation manual
for proper procedures and safety practices. Follow
proper procedures in this manual for proper
installation of the sandbagger.
Walk Around Inspection
1. Check condition of all safety decals. Clean
dirt or debris from all decals that are illegible.
Replace any decals that are missing or
illegible (Figure 12). See parts manual to oder
decals.
2. Inspect that all four belt screen shields are in
place and securely attached (Figure 2). Make
necessary repairs before operating.
3. Check condition of all hydraulic hoses and
electrical leads on host vehicle and
sandbagger. Check for cuts, excessive wear,
fraying, leaking oil or short circuit. Make
necessary repairs before operating.
Controls
The host vehicle boom ro bucket function control
lever, controls the operation of the sandbagger.
Moving the lever away from operator is required to
fill sandbags. Moveing the lever reaward reverses
the auger and should only be used momentarily in
the event of auger jam.
Read the host vehicle’s Owner’s Operator’s
manual for safety practices and proper operation
procedure and location of controls.
1. Bucket Fill Angle
Marks should be made on arm structure with
bucket loading edge (cutting edge) horizontal
at start of process to fill bucket (Figure 10).
2. Bag Fill Bucket Angle
To obtain the best flow from the sandbagger a
second mark should be made on the structure
indicating basic vertical position of the
sandbagger when filling sandbags (Figure 11).

Filling Sandbags
1. Two people are required to fill sandbags. One
person is located on the host vehicle operator
controls seat. The second person is required
to correctly place and hold the sandbags in the
fill location on the sandbag safety stand.
2. The mirror (Figure 7) must be so positioned
that the operator can see the person holding
and filling sandbags.
3. The person filling bags is to prearrange with
the operator that nodding of the head indicates
“START TO FILL”bag and the next nod
indicates “STOP”.
4. The host vehicle operator should set the
engine at approximately 2100 rpm so that
correct oil flow is supplied to the sandbagger.
5. Start bag fill procedure and continue to repeat.
One full bucket will fill 35 to 50 bags.
6. When bucket is empty, raise bucket enough to
free safety stand. Remove stnad. Stow stand
to side. Refill bucket and repeat above
procedure.
NEVER walk or stnad under the raised bucket
when installing safety stand.
ALWAYS check safety stnad before installing
for bending and/or any deformation.
Always replace bent or deformed safety
stands.
!Warning
Figure 11
OM0340
mark for bag fill bucket angle
DO NOT operate in REVERSE direction in
excess of momentary movement as this may
cause damage to the motor housing seal and
rubber bellows.
Variations In Sand
There are many variations in sand, from course to
very fine. With these variations sand changes
consistency when dry or wet. Sand also changes
dramatically in weight from dry to wet.
The sandbagger design permits operation with
most types of sand; however, due to sand moisture
content, and with travel, which causes packing
within the bucket, sand or other materials will resist
flow by standing vertically or tunnelling around the
auger.
The above variance in conditions will resist
emptying of the front and/or back areas in the
bucket. As an aid to assist in emptying the bucket,
the operator should raise the attachment and tilt it
back and forth to dislodge the sand pockets. The
safety stand must be removed prior to tilting.
A stick or similar object must NEVER be used
to dislodge sand while operating the
sandbagger. Use of a stick may cause
personal injury and/or damage to the
sandbagger mechanism.
Stalled condition
Should the sandbagger stall, due to a rock or
debris becoming jammed in the auger or screen, or
due to very wet sand having been compacted as a
result of travel, the control function may be
momentarily reversed. Should the stalled
condition not clear by momentary reversal, it will
be necessary to dump the sand out of bucket to
determine the cause.
!Caution
!Warning

12 ST1-075A Ia 12/98
Due to clay, fines and stones within sand it will be
necessary to clean the sandbagger to obtain good
flow.
Stones: If sand has stones larger than 1-3/
4 inches, the screens will stop
entry of these stones into the
auger area. As a result the dump
body should be checked for large
stones and or debris between
loads.
Clay or Fines: When sand is wet and contains
clay and/or fines, the material will
build on screens and auger flight
which reduces sand flow.
Sandbagger should be periodically
checked for this condition. Should
this condition exist it will be
necessary to wash or clean the
sandbagger screens to remove
build up.
Sand is corrosive and therefore it is important that
the sandbagger be kept clean. It is recommended
that the sandbagger be cleaned (washed) at the
end of each shift and before storing. It may also
be necessary to wash the sandbagger during a
shift to clean the screen or auger.
To clean:
•empty all sand from bucket
•shake bucket forward - run sandbagger
•tilt bucket rearward - shake and run
sandbagger
•repeat steps above, and wash thoroughly
•Remove safety stand and store
•lower the bucket until resting on the ground
•ensure that the sandbagger control (boom
function) is in neutral
•set host vehicle brakes
•stop engine
•unbuckle the seat belt, and
•exit the host vehicle using the hand holds

General Maintenance
Safety Decal Locations
Check condition of all safety decals. Replace any
decals that are missing or damaged. Clean dirt or
debris from all decals that are illegible (Figure 12).
Routine Inspection
Perform all maintenance inspections or service
requirements with the sandbagger attachment
on the ground and the host vehicle engine OFF.
Contact with moving parts can cause serious
injury or death.
Every ten hours of operation:
1. Inspect the four belt screen shields (Figure 2).
DO NOT operate without proper shields in
place. DO NOT replace belt shields with
standard belting. Replace with factory
supplied belting only. Contact with moving
parts can cause injury. Rocks jammed or
wedged between screen due to missing belt
shields can cause damage to screens and
drive mechanism.
2. Inspect elastomer springs for looseness.
Replace if there is no preload noticeable on
springs (Figure 9). Preload is correct when
elastomer spring expands against spacer ring.
Should it be necessary to replace elastomer
springs refer to Disassembly Procedures.
It is not necessary to remove screens or
screen supports to check elastomer springs for
preload. Contact with moving parts can cause
injury, be sure equipment is OFF before
performing inspection. Preload is checked by
using a small bar between the screen and
auger flight (Figure 15).
3. Inspect the screen support isolators. Replace
if isolators have broken or deteriorated (Figure
14).
Every 40 hours of operation:
1. Remove motor housing inspection cover
and check motor drive mechanism for;
Leaks - tighten or repair.
Sand entry into housing - inspect for broken or
worn push rod boots or for damaged or worn
auger drive shaft seal (Figure 15).
Slack in push rod joints*
Loose shaker bearing mechanism.*
* NOTE: Contact with moving parts can cause
injury, be sure equipment is OFF before performing
inspection. Slack or looseness is checked by using
a small bar between the screen and auger flight
(Figure 15).

Flow Control Valve Removal
(item 7, Fugure 19)
Remove cover plate (item 27) by removing the
eight lockwashers and bolts (item 28 & 19).
Disconnect the 3/4 inch hoses and fittings on valve
at the flow control assembly. Cap ends of open
hoses and fittings to prevent dirt from entering.
Loosen the two line nuts at item 6 and 8. Remove
the two bolts (item 5) which hold the valve in
place. Valve may be removed from housing.
Drive Module Assembly Removal
(item 23, Figure 15)
NOTE: The drive module assembly cannot be
removed with the push-pull rods installed. If push-
pull rods are removed, ensure that jproper length
measurements are taken prior to removal to
be able to duplicate rod length at reassembly.
Follow procedure for Flow Control Valve and
Elastomer Spring Removal.
Remove two rubber bellows from the push-pull
rods (item 15, Figure 12). Disconnect three grease
hoses from joints and bearing carrier (item 18,
Figure 19). Remove two 3/8 inch bolts and nuts
securing the drive module housing to the frame
(items 22 & 26 Figure 19).
NOTE: Mark shim stacks (item 21) as to location
so that they may be returned to same location at
reassemly in order to prevent distortion of the drive
frame resulting in premature bearing life.
Remove six socket head capscrew (item 20)
Remove drive module assembly from the housing.

Drive Module Disassembly (Figure 19)
1. Place drive module assembly in vice.
2. Check shaker bearing assembly for end play
(Figure 19) before disassembling the drive
module assembly. Shaker bearing end play
can best be checked using the following
procedures.
•Place dial indicator near center of shaker
drive plate (Figure 18).
•While using back and forth hand force
against ends of shaker drive plate read dial
indicator.
NOTE: If dial indicator reading is more than .010
inch, bearing assembly should be disassembled
and bearings replaced with bearing kit. Refer to
drive module reassembly if old shaker bearings are
reused.
3. Remove bolt (item 1) & grease fitting (item 11).
4. Remove four bolts (item 10).
5. Pull motor from assembly.
6. With blunt one inch brass drift remove the
coupling block (item 3). The bearing (item 4)
and seal (item 2) will remain in the housing.
7. Remove shaker bearing assembly from the
housing.
8. Remove bearing and seal from housing (items
2 & 4).
9. Remove push-pull joints by removing locking
bolts (item 13) & then drive out pins (item 12).
10. Remove shaker bearings (item 17) by
removing the lock nut (item 15), lock washer
(item 14) and nylos ring (item 16). A four inch
spanner wrench is required to remove lock nut
(item 15).
11. Inspect all components before
reassembly.
12. Motor seal kits are available with
disassembly/assembly instructions.
Drive Module Reassembly (Figure 19)
Reassemble in reverse order as noted in the
disassembly instructions. Care must be taken
regarding the following items.
1. When old shaker bearings are reused surface
grind the spacer ring (item 9) equal to the end
play plus .002 inch determined at disassembly
(see step 2 in disassembly) e.g. for .005 inch
end play plus .002 for preload remove .007
inch from spacer with surface grinder. New
bearing sets are supplied with a new spacer
ring as a kit.
2. Torque the lock nut (item 15) to 100-150 lb/ft.
Sockets are available for use with a torque
wrench. An adjustable spanner wrench with an
extension applying the force required relative
to wrench and extension length may also be
used, eg force (125 lbs) x length (1 ft) = 125 lb/
ft.
3. Torque bolt (item 1) to 100 lb/ft.
4. Torque six socket head capscrews (item 20) to
100 lb/ft.
5. After torquing six socket head capscrews,
install shim stacks which were removed (item
21).
NOTE: Shim stack must fill complete space
between modular housing and frame to within .010
inch before tightening through bolts and nuts (item
22 & 26) to 40 lb-ft.
6. The flow control valve is normally set at
adjustment point 6 for proper operating sped
(Figure 14, item 7).
7. Auger speed of 240 to 260 rpm must be
checked with sandbagger on host vehicle.
Higher number on flow control increases speed
and lower number reduces speed.
