GENERAL DESCRIPTION
The Westco Models 4500 Hydraulic Tubing Tongs are fast, safe, and accurate tongs for making up and
breaking out 1.315” to 4.75” (Model 4500) O.D. tubing. Hydraulic power is directed to a manually controlled
throttle valve and hydraulic motor unit. Fluid power input is converted to the rotary mechanical output,
which drives the tong’s gear train. The simple, but rugged gear train consists of a planetary type gearbox
mounted directly beneath the motor, and a gear reduction system, which provides the extra torque capacity.
The tong is suspended in the derrick or mast by a wire line and swung onto the tubing. Tong jaws grip
automatically and the safety guard door closes. Operate the throttle in the forward position, and the tubing is
automatically made up to the required specifications as indicated on the torque indicator gauge.

FIRST TIME START-UP PROCEDURE
The operator should read and follow these instructions before attempting to operate the tongs for
the first time. When preparing to operate a new or re-conditioned hydraulic tubing tong, or an
assembly that has been in storage, perform all of the operations listed below. Before operating (at
the beginning of each shift), perform daily operations in “Lubrication and Preventive
Maintenance” procedure.
TONG:
Clean tong and remove any packing material. Grease, oil, and lubricate brake band. Function
test linkage and shift mechanism for free operation. Suspend in derrick.
HYDRAULIC HOSES:
1. Adjust hydraulic system pressure to 500 PSI or less.
2. Shift tong to neutral position.
3. Engage hydraulic system clutch.
4. Push throttle lever toward tong
5. Allow hydraulic fluid to circulate with tong gearshift lever in neutral position and the
throttle advanced for approximately five minutes.
6. Set system pressure.
7. Check system for leaks.
8. If operating in cold weather, engage tong in high gear and rotate 2-3 minutes for warm-
up. Check tong linkage adjustments.

39
OPERATING INSTRUCTIONS
Tongs are assembled with parts carefully machined from selected materials. Each tong is thoroughly
tested and inspected and is shipped from the factory with confidence that it will efficiently perform
any job for which it is rated. The ensuing pages have been prepared for your guidance. These
procedures are necessary and should be followed for proper operation and maximum life of your
tong.
FLUID REQUIREMENTS:
To obtain the proper torque in making up and breaking out, the Tubing Tong requires a fluid volume
of approximately 35 to 40 gallons per minute (132.5 LPM to 151.4 LPM) at 2000 PSI (70.3 Kg/sq
cm) and a minimum of 10 GPM (37.8 LPM) at 1000 to 2000 PSI (70.3 to 140.6 Kg/sq cm). Every
effort should be made to keep the hydraulic system clean. The coupling on the tong is self-sealing
and should be used whenever the hoses are disconnected. Use of this type of coupling insures the
pressure and return hoses, four-way valve, and hydraulic motor being full of oil, minimizing spillage.
HOSE CONNECTIONS:
When connecting the hoses, ensure there is no pressure in the system. Detach the fluid pump from
the engine or shut the whole system down. ALWAYS CONNECT THE 1” (2.54 cm) FLUID
RETURN HOSE TO THE TONG FIRST, and then connect the fluid supply hose. ALWAYS
DISCONNECT THE FLUID SUPPLY HOSE FIRST. This prevents any pressure from building up
in the hydraulic motor and seal. When attaching the hoses to the tong, DUST CAPS SHOULD
ALWAYS BE USED WHENEVER HOSES ARE DISCONNECTED. Should the open end of the
coupling be allowed to come in contact with any dirt, it should be very carefully cleaned before re-
connecting and installing dust caps. A very small amount of dirt, sand, or foreign material can cause
serious damage to the pump, hydraulic motor and valves.

39
INSTALLATION AND MAINTENANCE OF TONG
1. Always wear eye protection prior to replacing dies.
2. Clean dies with wire brush daily to prevent damage to outside of tubing.
3. Inspect and change worn dies periodically to prevent slippage and damage to tubing.
4. Remove jaw and bushing from tong before changing dies.
5. Install dies correctly to ensure gripping on tubing. Dies must be installed with the teeth
facing the direction of rotation.
6. Roll pins in jaw and bushing must be installed correctly to prevent dies from falling down
well when operating tong.
SUSPENSION OF TONGS IN DERRICK
1. Suspend the tong in the derrick with as long a line as possible, at a height to grip the tubing at
least 6” ABOVE THE UPSET. The angle of hanging line from vertical when tongs are on
tubing MUST NOT be great enough to pull the tong off the pipe.
2. Attach Back-up line.
a. A Back-up line, automatic or retraction, is attached to the Back-up Ring. The Back-up
line must be of sufficient strength and be properly secured. BACK-UP LINE MUST BE
HORIZONTAL TO TONG: THAT IS, IT MUST NOT PULL UP OR DOWN ON THE
TONG WHILE IN OPERATION. For correct torque readings, the Back-up line MUST
BE ON A 90ANGLE WITH THE TONG.
b. Westco International recommends the use of a safety sling to prevent injury of personnel
caused by failure of the main Back-up line or stiff-arm assembly. The safety sling
attached to the safety eye on the back of the tong and fastened to the rig or to a secure tie
down.
NOTE: A Back-up line must always be used, with or without the coupling Back-up
assembly.
9. Connect hydraulic hoses and start power unit.
10. Swing tong on tubing joint. Advance the throttle enough to take the slack out of the Back-
up line. This will put the tong in a level position.

39
TONG FAILS TO GO ON TUBING:
If the tong fails to go onto the tubing, it is probably because the jaw is partially closed. In this case,
run the motor in the direction that will fully open the jaw, and then proceed to install the tong on the
tubing. If this fails to work, check both the jaw and bushing for proper size and installation. Refer to
chart below.
JAW AND BUSHING SIZES:
Jaw and bushing sizes are stamped according to the actual O.D. of the tubing that they will fit –not
the normal size of the tubing.

CHANGING OR REVERSING JAW AND BUSHING
The jaw and bushing are reversible, depending upon the desired direction of rotation. If the jaw is
installed on the left side (standing in front of the tong, as you look into the opening of the tong), the
tong will rotate the tuning to the left. When the jaw is installed on the right side, it will rotate the
tubing to the right (the direction of tubing rotation when going into the hole).
REMOVAL OF JAW AND BUSHING:
Position the tong as if it were to go onto the tubing. Reverse the bushing. Reverse the motor and
move the outer ring slightly. This will remove any force against the pivot pin of the jaw so it will
come out easily. Remove the pivot pin and jaw.
NOTE: It is difficult to remove or install the jaw while the bushing is still in place.
REVERSAL OF JAW AND BUSHING:
Remove the jaw and bushing as outlined above. Move the outer ring slightly so there will be room to
get the lip of the jaw in back of the front roller of the outer ring. Make certain that the jaw and
bushing are the correct size. Install the jaw. Install the bushing.

39
CHANGING THE TUBING TONG BRAKE BAND
Align the opening of the inner and outer rings with the opening in the tong frame. Remove the two
cap screws from the brake band cover plate. Apply grease liberally to the lining of the new brake
band and to the inside of the eye on each end of the band. Put the new brake band on the inner ring
and remove the wooden spacer. If the new brake band does not have a spacer, a piece of wood 5 ½”
long can be inserted. The brake band cover can then be closed and the two cap screws installed.
NOTE: When the cover plate is down, ensure that the two brake pins in the cover plate enter the eye
openings at each end of the brake band.

39
RUNNING THE TONG
*Before operating the tong for the first time, refer to “First Time Start-Up Procedure”
MAKING UP THE TUBING
With the tong suspended, position gearshift lever (located towards the front of the tong) in high gear.
With the safety guard on the front of the tong open, position tong onto the tubing. (The safety guard
will automatically close as tubing enters). It is necessary for the tong to be in this position for the
jaws to grip. DO NOT SWING THE TONG ONTO THE TUBING TOO HARD, AS IT MAY
CAUSE THE TONG TO BOUNCE OFF. Engaging the throttle causes the jaws to grip and rotate the
tubing. The pressure at which the pump unit is set determines the make-up torque.
TORQUE CURVE
OIL PRESSURE
On high-pressure well, stall pressures should be higher. High torque and critical joints should be
made up using the manufacturer’s recommended torque values and taking direct readings from the
torque indicator gauge. Accurate readings are also dependent upon proper tong suspension.
To release the tongs from the tubing, reverse tong by pushing the throttle back until the gap in the
rotor becomes in alignment with that of the case. The jaws will automatically release.

39

39
TONG LINKAGE ADJUSTMENT
SHIFT ROD ADJUSTMENT
Shift rod adjustment is accomplished with jam nuts located on each end of the rod. Adjust gearshift
handle in neutral position.
THROTTLE ADJUSTMENT
The throttle rod adjustment is set with the safety arm and with the door in open position. Adjust
safety bar to match the slot in the safety arm and secure by tightening jam nut.
NOTE: Proper adjustment allows full throttle in both directions with the door closed and prevents
throttling when door is open.
GEAR SHIFT TENSION ADJUSTMENT
Adjusting gearshift tension is accomplished by turning setscrew in until gears will not shift and
backing out setscrew until shifting is smooth. There will be approximately three threads of the
setscrew exposed beyond the transmission cover when shifting mechanism is new. Setscrew position
is also a wear indicator for the shift rod fork.
HYDRAULIC OIL SPECIFICATION
The hydraulic system fluid affects performance and service life of all other components of a hydraulic
system. Some of the factors especially important in the selection of oil for use in a hydraulic system
are:
1. The oil must contain the necessary additives to ensure high anti-wear characteristics. Not
all hydraulic oils contain these in sufficient amounts.
2. The oil must have proper viscosity to maintain adequate sealing and lubricating quality at
the expected operating temperatures of the hydraulic system.
3. The oil must have rust and oxidation inhibition for satisfactory system operation.
Viscosity of fluid is a measure of its resistance to flow as well as its ability to prevent metal-to-metal
contact of moving parts. It is recommended that the following maximum and minimum viscosity
ranges of the oil at start-up and during running be maintained:
Nominal: 150-3000 viscosity at 100F (38C)
Running: 70-250 viscosity
At start-up: 4000 viscosities maximum
An anti-wear type of heavy-duty industrial hydraulic oil is recommended. This anti-wear type of oil
offers superior protection against pump and motor wear, and has the advantage of long service life.
In addition, these oils provide good demulsibility as well as protection against rust. A good grade
SAE 20 “MS” automotive crankcase oil can be substituted. For most efficient operation, the
temperature of the oil should not exceed 150F (66C).

39
GREASE SPECIFICATIONS
Due to the operating environment of the tong, water insoluble grease is required. The grease should
have high pump ability to permit application during very cold weather. The grease recommended for
cold weather operation is Shell B&B Code 70919, which conforms to Government Specification
MIL-G-10924-C. In milder climates, all-purpose grease such as Shell Alvina #2 is recommended.
STEPS TO AVOID CORROSION
Every trip, lubricate all grease fittings with the recommended grease. With an oilcan, lubricate the
following: throttle mechanism and the shift mechanism. Lubricate brake band and friction surface
with only enough light oil to keep the surface from rusting when the tong is not in service. If the tong
does not grip the pipe, the cause may be too much grease on the brake band. This can be remedied by
wiping the brake band and friction surfaces clean of all grease, later re-lubricating with grease. The
tong should be cleaned periodically or after each shift when used around salt water.

39
IMPORTANT
LUBRICATION AND PREVENTIVE MAINTENANCE
To obtain the long life and best performance from a tong, the operator must adhere to the following
instructions on lubrication and preventive maintenance. Areas to be oiled or greased, and proper care
of the hydraulic hoses and couplings. The daily instructions pertain to routine or daily operation of a
tong and not to new equipment. For new tongs, follow instructions given in “First Time Start-Up
Procedures”. The time intervals given in the instructions refer to actual hours on the tong.
ITEM 1:
After every trip, lubricate the following with 30W oil or equivalent, throttle mechanism shift
mechanism, guard door spring, front end of reverse rod and jaw pins.
ITEM 2:
After every trip, all grease fittings should be lubricated with the recommended grease. In
addition to those shown, there are fittings on each guide roller shaft, one on the bottom
transmission cover and one on the underside of the handle. There is no danger of over-
greasing the tong. Under continuous operations, such as when tong is used for light drilling
operations, grease the tong every hour.
ITEM 3:
During connecting and disconnecting hoses, inspect couplings to ensure that all openings are
free of dirt and debris. Use clean rag and solvent when cleaning, if required. Take proper
precautions to ensure that the solvent does not enter hose. Hoses should be wiped clean, and
if storage is necessary, install dust covers and store in a clean, warm climate protected from
direct sunlight.

39
STORAGE
PREPARING TONG FOR STORAGE:
When a tong is to be stored or removed from operation, special precautions should be taken to protect
the interior and exterior of the tong from rust accumulation and corrosion. It will be necessary to
remove all rust or corrosion completely from any exposed part before applying a rust preventive
compound. Therefore, it is recommended that the tong be processed for storage as soon as possible
after removal from operation. Storage should be in a building, which is dry and can be heated during
the winter months. Moisture absorbing chemicals are available commercially for use when excessive
dampness prevails in the storage area. The recommended storage preparation is detailed below.
TEMPORARY STORAGE:
To protect a tong during storage for periods of 30 days or less:
1. Clean entire exterior of tong with solvent and thoroughly dry. Cleaning is especially important if
unit has been used around salt water.
2. Grease and oil the tong as recommended under “Lubrication and Preventive Maintenance”
procedure.
3. Cover the entire unit with a good weather-resistant tarpaulin or other cover if it must be stored
outdoors. A clear plastic cover is recommended for indoor storage.
EXTENDED STORAGE:
To protect a tong for storage for periods exceeding 30 days, proceed as follows:
1. Perform Steps 1, 2 and 3 of “Temporary Storage” procedure above.
2. Spray all exterior surfaces of the tong and power unit with a suitable liquid automobile body wax,
a synthetic resin varnish, or a rust preventive compound.
3. Cover the tong and power package with a good weather-resistant tarpaulin or other cover if it
must be stored outdoors. A clear plastic cover is recommended for indoor storage. The stored
unit should be inspected periodically. If there are any indications of rust or corrosion, corrective
steps must be taken to prevent damage to the parts. Perform a complete inspection at the end of
one year and apply additional treatment, as required. For restoring the tong to service, refer to
“First Time Start-Up Procedure” on page 4.

however, that power-driven equipment is only as safe as the operator who is at the controls, it is
extremely important that the operator observe the following safety precautions.
1. Operate the tong from the back-up line side only (does not apply to front control tongs).
2. Never change a jaw or put hands within the rotating parts of the tong while tongs are connected to
hydraulic hoses.
3. Never remove or operate the tong without the guard doors in place.
4. Do not exceed the maximum pressure for which this system is rated.
5. Always use a back-up line for all tong operations.
6. Keep loose fitting clothing away from the rotating parts of the tong.
