FOREWORD
This Operator's Manual contains the essential operating instructions and routine servicing proce-
dures for the day-to-day care, adj ustrnents , and I ubrication of the wheel loader. This manual will
enable the operator to accomplish the job which the unit has been designed to do and to gain the
maximum in trouble-free operation and long life for the TL-16 TRACTOLOADER.
The Model TL-16 TRACTOLOADER has two distinct features which greatly improve its operation
and output. They are:
A. THE HYDRAULIC TORQUE CONVERTER
1. The torque converter, located between the
engine and transmission, provides a very
flexible hydraulic connection between the
engine and transmission, perrm ttmg a
smooth, shockless flow of power. It prevents
stalling of the engine when the unit is over-
loaded.
2. It means less wheel slippage because the
converter automatically adjusts the speed
of the wheels to the load.
3. The converter allows the machine to crowd
forward into the pile at the same time the
bucket is tipping back and raising, without
lugging the engine down. This eliminates
slipping the clutch to load the bucket. If
the bucket starts to "stall out," slight
pressure on the brake pedal will hydrauli-
cally release the range clutch which in turn,
stops the machine from crowding into the
pile. When the bucket starts to raise,· re-
lease the brake pedal.
NOTE: A control lever is provided for dis-
engaging this automatic clutch release fea-
ture if operating conditions make it undesir-
able. For positions and location, refer to
page 11.
B. THE FULL POWER SHIFT TRANSMISSION
1. The full-power-shift transmission means
selecting the speed range and reversing the
direction of the unit without shifting gears.
One lever controls all speeds - forward and
reverse.
2. The single lever control of the full-power-
shift transmission allows the operator to
change from any forward speed to any re-
verse speed at any time by using only one
lever.
3. The advantages of hydraulic torque multi-
plication are further extended by the con-
stant mesh planetary gearing in the trans-
mission. This combination makes available
an "infinite" number of speed ratios (within
design limits of the converter and trans-
mission) with three forward and three re-
verse speed ranges.
4. It provides direct power from the engine
crankshaft through a series of gears to the
loader hydraulic pump.
The practice of going to your Allis-Chalmers Dealer for all parts and repair work, other than routine
care and adjustments, is encouraged, as the dealers are kept well informed by the factory regarding
parts and advanced methods of servicing Allis-Chalmers products.

MODEL TL-I6 TRACTOLOADER
The Model TL-16 Gasoline Wheel Loader is a
16,050 pound (less bucket), four wheel drive,
wheel-loader unit powered by a 6 cylinder
gasoline engine.
Power from the engine is transmitted directly
to the single stage type torque converter by
means of a Universal Joint. The torque ratio
in the converter is increased 3.5 to 1, then
transmitted to the full-power-shift transmission.
A power train in the transmission serves the
hydraulic system pump whenever the engine is
running. Forward or reverse direction of the
shift lever into any speed range transmits
power from the transmission through the uni-
versal drive shafts to both front and rear dif-
ferentials and axles.
The transmission provides 3 forward speeds
and· 3 reverse speeds ranging from 0-4.0
M.P.H. in low gear to 0-27.0 M.P.H. in high
gear, at the rated engine speed of 2200 RP.M.
(governed full load). Control of the loader is
accomplished hydraulically by the transmission
mounted hydraulic pump, control valve with
two control levers, two lift cylinders, two dump
cylinders, and the necessary hydraulic lines.
There are no exposed hoses or fittings around
the operator's compartment. The hydraulic
tank, located behind the operator's seat, pro-
vides mounting of the control valve and levers,
piping and safety valves. Short, external piping
on each side of the operator's seat directs the
oil to the left side and the right side lift and
dump cylinders.
The loader design provides top visibility,
strength, and servicing accessibility. The
loader side frames are mounted to the axle
housings with heat-treated pins. The rear
stabilizer shroud and heavy steel seat frame
assembl yare bolted together with the side
3

- SPECIFICATIONS OF LUBRICANTS -
A. ENGINE CRANKCASE LUBRICANT
Always use an oil of high quality, manufactured
by a dependable oil company who has estab-
lished a reputation for quality products and
whose success depends upon maintaining such
quality.
ATMOSPHERIC
TE\IPERATURE VISCOSITY
90 0 F. and above Use SAE

Manufacturers of lubricants recognize the im-
portance of the qualities required for use in our
equipment and they are cooperating fully to
assure the use of only those oils which fulfill
these requirements. The oil distributor and oil
manufacturer are to be held responsible for the
results obtained from their products.
The outstanding Iubricating requirements for
efficient operation of the engine are: the main-
taining of piston rings in a clean, free condi-
tion; absence of hard carbon and ·'varnish"
deposits on or within engine parts; the preven-
tion of bearing corrosion, and the promotion of
general cleanliness within the engine.
Proper operation and maintenance of the engine
are necessary to obtain the desired results from
the lubricating oil.
B. AIR CLEANER
Use the same viscosity oil in the air cleaner as
used in the engine crankcase.
CAUTION: Do not use an oil that foams.
C. TRANSMISSION AND CONVERTER LUB-
RICANT
Lubricate these assemblies with a good grade
of Transmission Fluid type "C" oil purchased
from a reputable oil company.
D. HYDRAULIC SYSTEM
A good grade of rust inhibiting hydraulic oil or
automotive crankcase oil having a viscosity of
210-225 S.S. U. at 100 0 F. (SAE lOW) is recom-
mended for use in the hydraulic system.
NOTE: Do not use an oil that foams.
No specific brand of oil is recommended. Use
only products qualified under the above VIS-
cosity specification and recommended by re-
putable oil companies.
E. FRONT AND REAR AXLE LUBRICANT
Both the differentials and planetary hubs use
Multipurpose (E.P. type) gear oil of the fol-
lowing viscosities:
ATMOSPHERIC VISCOSITY
TEMPERATURE
Above 32 0 F. Use SAE
140
32 0 F. and below Use SAE

F. PRESSURE GUN LUBRICANT
Use a ball and roller bearing lubricant with a
minimum melting point of 300 0 F. This lubri-
cant should have 'a viscosity range so as to
assure easy handling in the lubricating gun at
the prevailing atmospheric temperature, and
MUST be waterproof.

- SPECIFICATIONS OF FUEL -
The engine for the TL-16 loader has been
designed to burn ordinary gasoline. For best
economy and performance, use a gasoline with
a rating of 70 octane or higher.
In addition to using quality fuels and lubri-
cants, always use clean containers for storing
and handling.
- PREPARATION OF MACHINE FOR USE -
Make a complete inspection of machine to make
sure no parts have been lost or damaged while
in transit.
Inspect oil level in engine crankcase.
Check oil level in transmission.
Check oil level in loader hydraulic system.
Check oil level in differentials.
Check oil level in planetaries.
Fill cooling system with clean soft water.
Fill fuel tank with gasoline.
Inspect oil level in air cleaner cup.
Check and lubricate all points where fittings
are provided for a pressure grease gun.
Check level of electrolyte solution In the
battery.
Turn fuel line shut-off cock to the open posi-
tion.
Check level of brake fluid in master cylinder.
Check tire pressure (14:00-24 - 40 Ibs.).
Check all bol ts to be sure they are tight. By
tightening the bolts at this time and again at
the end of 10 hours, the possibility of their
becoming loose and enlarging the bol t hol es
will be eliminated.

- STARTING AND STOPPING THE ENGINE -
A. STARTING ENGINE
Place the power shift lever and bucket control
levers in the neutral position. Turn ignition
switch to "on" position. Depress foot throttle
pedal as far down as it will go. Turn ignition
key to "start" position and hold until engine
starts (if weather is cool, pull out choke con-
trol located at lower front side of operator's
compartment - when engine has turned over two
compression strokes, push in choke control)
release the key and reduce accelerator pedal to
half speed until water temperature reaches
160 0 to 180 0 F. and transmission oil is warm
before placing load on engine.
For positions of levers, pedals,
gauges, etc. see Figure 5.
IMPORTANT: Converter oil temperature must
not exceed 250 0 F. Check temperature gauge
at regular intervals. See page 47 for further
ins truetions.
When engine IS started, observe the engine
lubricating oil pressure indicated by the gauge.
With engine running at full speed and with the
engine coolant at normal operating temperature
(160 0 to 180 0 F.) the oil pressure should be
between 30 and 45 p.s.1. If the oil is cold, no
pressure may be indicated by the gauge for 15
seconds after the engine starts, but if the
pressure does not then rise to normal or above,
the engine must be stopped immediately and
the cause determined and corrected.
B. STOPPINGENGINE
Release foot throttle pedal and turn ignition
key to "off" position and remove key. The
engine will now have no possible means of
starting.
NOTE: Always allow engine to idle at least 2
minutes, so that engine may cool gradually and
uniformly.
Be sure that the ignition key is turned to the
"off' position before leaving the operator's
compartment. Because of the constant flow of
electricity to the gauges on the instrument
panel, the battery may be drained if key is
left on.
Cover the exhaust pipe at the end of each days
operation to prevent rain from entering while
engine is idle.

BEFORE STARTING THE ENGINE, MAKE
SURE THERE IS SUFFICIENT OIL IN THE
LOADER HYDRAULIC SYSTEM AND TRANS-
MISSION HYDRAULIC SYSTEM.
It is important that the operator familiarize
himself with the various controls and instru-
ments provided for operation of this unit (see
Fig. 5). Although many of these controls are
similar to other loaders, there are important
differences, and it is not wise, regardless of
previous experiences, to operate the loader
before fully understanding the purpose of each
control and instrument.
DRIVING TIP - The transmission is full-power
shifting. It is possible to upshift or downshift
the transmission at wide-open throttle regard-
less of load. However, do not downshift from
intermediate or high range to low range at
speeds in excess of 4 M.P.H. Do not shift
down from high to intermediate range at speeds
in excess of 10 M.P.H.
The Full-Power-Shift Transmission is con-
trolled by a single lever which allows the oper-
ator to change from any forward speed to any
reverse speed at any time. The accelerator
pedal is located under the right foot, while the
11

GENERAL OPERATING INSTRUCTIONS - CONTINUED
pedals for the four-wheel power brakes are
located one on each side of the steering col-
umn, either pedal operates the master cylinder.
The mechanical parking brake is located to
the left of the operator and may be operated
manuall y by pulling back on the lever to lock
the brake, which is located at the lower front
side of the transmission at the drive shaft.
This mechanical parking brake operates inde-
pendently of the service brakes and may be
adjusted according to the wearing of the brake
lining by turning the mechanical parking brake
lever knob.
NOTE: It is a good habit to set the parking
brake before leaving the machine, but remember
to release the brake before putting the machine
back to work.
The rear axle disengagement lever is located
to the right of the operator (see Fig. 5). To
disengage the power from the rear axle, push
forward on the lever and to put power back
into the axle, pull back on lever.
NOTE: Four wheel drive should always be us ed
when working the machine. The rear axle dis-
connect may be used for road travel and some
light materials work.
The one lever, Full-Power-Shift Transmission
is automatically declutched by applying brake
pedal pressure, and returns to the same speed
range when the brake is released. However,
when precise control of the machine is re-
quired on grades, this automatic cl utch release
may be undesirable. Accordingly, a control
lever is provided so the operator can easily
disengage the automatic release feature as
required. When changing control lever position,
the brake pedal should be fully released. For
location of control lever, refer to Fig. 5. Also
see "CI utch Cut-Off Valve," page 43.
To operate the loader, place the one lever
transmission control in neutral position and
start the engine. Move the lever to select the
desired direction and speed range. See Fig. 5,
page 11 for shifting procedure.
A FEW SUGGESTIONS FOR LOADING THE
BUCKET AND MANEUVERING THE MACHINE,
1. A black spot on the cylinder head and an
adjustable pointer, located at the rod end
of the right dump cylinder, are supplied as
an indicator to determine correct dig posi-
tion for all boom mounted attachments; be
sure they are lined up before penetrating
the stock pile.
2. Lower the bucket to ground level. Loader
is now ready to be driven into the stock
pile. If bucket starts to stall out while
digging in hard material with the accel-
erator pedal depressed to full throttle, the
penetration will be assisted if the operator
touches the power brake pedal lightly for
short periods with his left foot and pulls
back on the bucket control lever at the same
time. After the bucket is fully retracted,
pull back on the boom control lever to raise
the bucket. Normally, the accelerator pedal
should be fully depressed during the entire
loading portion of the cycle.
3. The operator will find that, In most mater-
ial, the first gear forward will be the most
satisfactory gear for loading, while any
gear in reverse (according to conditions).
may be selected with the one lever trans-
mission control to maneuver the machine.
4. Although the power brakes can be operated
with either left or right foot, the operator
can safely control the machine when ap-
proaching a truck by keeping his right foot
on the accelerator and his left foot ready
for the brake at all times.
5. The purpose of the two brake pedals is to
provide the operator with a choice of using
either foot to operate the brakes.
12

GENERAL OPERATING INSTRUCTIONS - CONTINUED
6. The one-lever control, full power shift
transmission permits the TRACTOLOADER
to maneuver safely in close quarters be-
cause the machine will stop with the range
clutches still engaged by removing your foot
from the accelerator. Because the clutches
are hydraulically controlled there is auto-
matic compensation for normal wear - no
adjustments are necessary.
7. Return the raise control lever to neutral
position immediately after the lift cylinders
reach the end of the stroke. Otherwise, the
hydraulic pump is unnecessarily subjected
to excessive load.
The torque converter, in conjunction with the
full power shift transmission, makes it possible
to almost completely eliminate wheel spinning.
However, short tire life will result if driving
wheels are allowed to spin excessively.
The bucket is lifted by pulling back on the
outer control lever. It is lowered by pressure
when the control lever is moved forward from
neutral position. When the end of the cylinder
stroke is reached, either up or down, the con trol
lever should immediately be returned to its
neutral position. The bucket can be "floated"
down by moving t he lift control lever to its
extreme forward position.
NOTE: With the bucket empty and in float
position, the bucket will automatically be
stopped about three feet above the ground when
lowering in the full tip-back position. This
added feature is a reminder for the operator to
start lining up the indicator (located at the rod
end of the right dump cylinder) to as sure the
correct dig position by the time the bucket
reaches the ground.
The bucket is dumped by pushing forward on
the inner control lever. The speed of dumping
can be controlled by this lever. If material has
a tendency to stick in the bottom of the bucket,
it can be jarred by bumping the stops. This is
done by moving the control lever back and forth
rapidl y. This should be done only under ex-
treme sticking conditions.
The bucket, in addition to the automatic tip-
back, during the boom raising cycle, can be
tipped back at ground level to increase the pay
load when handling loose material. This means
that the dump cylinder piston rods must be ex-
tended to level the cutting edge when penetra-
ting the pile, and can be retracted with break-
away effect during the loading cycle to obtain
a full load in the bucket.
By placing the Boom Control Lever in the
"Float" position rather than in down pressure,
it is possible to return the bucket to the proper
digging position with the Bucket Control Lever
at the same time the booms are being lowered.
This practice is particularly advantageous on
short hauls and stock pile work. A check valve
is located in the top front side of the control
val ve and is connected into the Boom lowering
lines so that oil may be transferred from the
bottom side to the top side of the lift cylinders
as required to keep the cylinders full of oil at
all times.
It is possible to create extremely high pres-
sures in the dump cylinders by such practices
as back-dragging or bulldozing with the bucket
and raising the booms with the bucket dumped.
Although two safety valves have been provided
in the hydraulic system, in addition to the main
relief valve, to safe-guard the loader linkage
against those high pressures; such practices
should be avoided whenever possible.
One safety valve (set at 1350 P.S.I.) is located
inside the hydraulic tank on the right side of
the manifold plate (as seated in operator's
seat) and is connected into the bucket dump
line; while the other valve (set at 2000 r.s.r.:
is located on the left side of the manifold plate

and is connected into the Bucket Return Line.
Both of these valves have been correctly ad-
justed at the factory and require no further
adjustment in the field.
A third valve (check valve) IS located inside
the hydraulic tank and connects the pressure
side of the main control valve to the tail end
of the dump cylinders.
A valve for limiting pressure in the power steer-
ing system is provided and is located in the
side of the power steering pump housing. This
valve is properly adjusted at the factory for
an opening pressure of 750 P. S.1. and requires
no further adjustment in the field.
When loads are carried for any appreciable
distance, the bucket should be carried as close
to the ground as practical since the best over-
all balance is obtained in this position, and
with the tip-back feature, the load can be car-
ried low with less spillage.
THE BUCKET SHOULD ALWAYS REST ON
THE GROUND WHEN THE UNIT IS NOT IN
OP ERATION. DO NOT ATTEMP T TO SER-
VICE OR ADJUST ANY PART OF THE LOAD-
ER WHEN THE BUCKET IS IN A RAISED
POSITION - UNLESS IT IS SUITABLY SUP-
PORTED BY MEANS OTHER THAN THE
HYDRAULIC LIFT CYLINDERS.
