nozzle and the ultimate distribution of Uquids (from their own container) carried in the trailer. When not used for this purpose, a
cover plate (Illustration 3, E) is attached to the rear of the tailgate
as are slots far holding the cover plate.
When the trailer is to be used for dumpjng, the permanent body
lock (Illustration 2, H) should be released. This is an added safety
lock. It can be released by unscrewing the Permanent Body Lock
Thumb Nut until the Permanent Body Lock Bolt clears the Permanent Hold Down Strike. (Illustration 2, C).

C o ~ p l i n gthe Trailer
Due care should be exercised when coupling or uncoupling the
trailer so that it will not get out of control.
A rope (not furnished) should be run through the hole at the
(Illustration 2). This rope shouId be long enough to
top of "A" & 'WB"
reach the motivating vehicle. It is for convenience in dumping the
trailer and in operating the tailgate.
To couple-up the trailer t o a jeep, lift up the pintle hook lock,
and raise the latch of the jeep. Raise the tongue of the trailer and
place the Lunette Eye IIllustration 1, C) in the hook. Close the pintle
hook and be sure that the lock is down in place.
Ofisrating the Stanchion
After the trailer has been coupIed to the jeep or truck, pull out
the Stanchion "T Pin" (Illustration 4, E, Page 7) and raise the
Stanchion (Illustration I, 30) to a parallel position with the tongue
of the trailer. The Stanchion "T Pin" will automatically be drawn
back to position when the proper position is reached. Before uncoupIing trailer, pull Stanchion "T Pin" and lower the Stanchion to a
90 degree angIe to the tongue of the trailer. As soon as this position
is reached, release Stanchion "T Pin" and it wilI lock ir. place.
Using the Trailer
When using the trailer for cargo work, the permanent body lock
(Illustration 2, C: and H) should be fastened. This acts as a safety
catch to make certain that the body will remain in a parallel position
Dumfii~tgthe Trnilar
The trailer is dumped by activating the dump release assembly.
This is accernpIished by pulling the dump reIease assembly lever forward. You may do this either by puIling the lever fomvard manually
or by manually pulling a rope attached at "E" (Illustration 2). This
releases the body dumping catch shown a t "G" (Illustration 2). To
bring the body back to its original position, pull down on the front
of the body bin untiI it is in a horizontal position and the plunger

Preparing the Trtiilsr for Storage
Jack up trailer and remove tires from wheels. Keep tires in a
cool dark room. Since painting is a. preservative, the only parts that
need additional treatment are the unpainted materiais on the trailer.
These should be treated with a few drops of oil or a thin film of
grease. Particularly is this important in the following: Bearings and
plunger in the body dump release mechanism, the spring plunger in
the lunette eye assembly, and the bearing blocks in the tailgate release
assembly.
Rigging Poi~ttsWhen Transporting the Trailer
(When not crated)
Draw a rope through the Lunette Eye (Tllustration 1, C) and
fasten securely t o the flow. Then draw a rope through the holes in
each skid plate (Illustration 3, R) ; and fasten swnrely t o the floor.

1. The Frame Assembly
THE FRAME--is an all steel construction and consists principally of two 3 inch channels, parallely placed, with a front lateral tie
of 3 inch channel and a rear lateral tie of 2 inch channel, reinforced
with 11 gauge vertical gusset braces. Due to its rugged design and
materials, the frame normally should require very little attention.
Vehicles which have been in an accident of any serious nature which
may result in sprung pads should be carefully checked for proper
alignment t o avoid tire wear, Excessive tire wear or the swaying
of the trailer may indicate a sprung or misaligned frame. The most
convenient way to cchck alignment is t o turn the trailer bottom side
up and checking should be done from the front of each frame siderail and also from the ,rear end. The tongue should also be checked
a t the same time.
If the Permanent Body Lock
be knocked off, a
1)
new one can be
welded into place.
PERMANENT HOLD DOWN LOCK
It is also a simple matter to renlace the Permanent Body Lock Bolt or Permanent Body Lock Thumb
hut, in the event they are lost or broken.
A Zerk Fitting is on the front end of the frame (Illustration 6).
It should be lubricated with a Zerk Gun every 1000 miles or monthly.
Use CG1, General Purpose Grease, No. 1 or 0 f o r lubrication.

Removing Tires from the Wheel
First, let the air escape fmm the tire by
removing the valve stem core. Then insert;
the tire tool in the slot of the rim and pry

Re#lacement of Worn w Broken Studs
First, remove the wheel from the hub. Next, remove jam nut
from the atud which is to be replaced. (Jam nuts are located on the
back side of the hub), Then using a l/z inch punch, drive out the stud
or studs, driving from the back side. Finally place new stud in position with the shoulder placed so that it will fit into the groove in the
hub as it is driven into position,
Caution: Studa marked "L" should be used only on the left wheel
which is on the left side of the traiIer when the observer stands facing
the direction of travel, Studs marked "R" should be used only on
the right wheel. If studs are used on wrong wheel, the nuts will work
loose and wear out or break the studs, and the wheel will come off.
Wheel Bearings
The wheels are m i e d on two opposed tapered rolier bearings.
Bearings are adjustable for wear and their satisfactory operation and
long life depends upon periodic attention and carrect lubrication. To
a
dI'
with a jack ao that tires clear the floor. (2) With hands, test the sidewise shake of the wheel. If bearings are adjusted too loose, the shake
of the wheel will be perceptible. If bearing adjustment is too tight,
the bearings will bind and the roIIers may break or become overheated.
T o adjust: I. With wheels still on jack, remove hub cap,
2. Tighten adjusting nut until wheel binds, at the
same time rotating the wheel to make sure all
bearing surfaces are in proper contact.
3. Then back off nut about I J 6 turn or more if necessary, making sure wheeI rotates freely.
4. Replace locknut.
5. When hub is completely assembled, test wheel
shake before removing jack.
When replacing hubs, the hubs with the right hand threaded
studs are placed on the right hand side. Those with the left hand
thread, on the Ieft side.
I t is recommended that every 5,000 miles, or every six months,
the wheels be removed and cleaned, the bearings repacked with new
grease (WB2, wheel bearing grease). If the grease seals are damaged
or the bearings or bearing cups are pitted, they should be replaced.
B. AXLE ASSEMBLY
If the trailer "whips" or the tires become excessiveIy worn or
scuffed on the inside or outside of the trailer, the difficulty may be
due to a loose wheel, shifting of load, or a bent axle. First, check to
see that the load is properly distributed. Then cheek the stud nuts
on both wheels to see that they are tight and that both tires are inflated to the correct pressure of 35 pounds. If the whipping persists
after checking the above features, then the trouble may be due t o a
sprung axle. Inasmuch as the axIe cannot be straightened except in
a well equipped shop with a power press, if this occurs in the field,
it is best to replace the axle.
