1.0 GENERAL INFORMATION
This manual provides instructions for the
installation and operation of the TDI
TurboTwin™ Model T30 ML air motors. If
there are questions not answered by this
manual, please contact your TDI
TurboTwin™ distributor or dealer for
assistance.
The T30 ML is a turbine driven air motor
with a .625” diameter keyed output shaft.
The T30 ML is designed for installation on
an oil pump with D-type mounting flange.
The T30 Series motors are suited to operate
within a wide range of inlet air pressures and
ambient temperatures.
A pressure regulator installed within 10 feet
of the motor can be used to adjust pressure
to the motor.
The T30 Series motors are designed for
operation with compressed air or natural
gas. Moderate amounts of foreign matter or
liquid in the air stream will normally not
adversely affect T30 Series motors.
As with all other TDI TurboTwin™ models,
no lubrication is required in the supply air.
You need to review the rest of this manual
before installing your TDI TurboTwin™ T30
Series motor.
1.1 WARNINGS, CAUTIONS, & NOTES
Throughout this manual, certain types of
information will be highlighted for your
attention:
WARNING - used where injury to
personnel or damage to the
equipment is possible.
CAUTION - used where there is the
possibility of damage to the
equipment.
NOTE - used to point out special
interest information.
1.2 INSTALLATION and SERVICE
The TDI TurboTwin™ T30 Series motors
provide distinct advantages of size and
efficiency compared to electric motors,
vane-type, or other turbine-type air motors.
It is important to properly install the motor to
receive full benefit of these advantages.
Repair technicians or service organizations
without turbine motor experience should not
attempt to repair this machine until they
receive factory approved training from TDI,
or its representatives.
Proper operation of your TDI TurboTwin™
T30 Series motor will assure continued
reliable and superior performance for many
years.
WARNING
The TDI TurboTwin™ T30 Series motors
must be installed and operated in
accordance with the instructions given in
this manual. Failure to properly install the
motor or failure to operate it according to
these instructions may result in damage to
the motor, the engine, or cause personal
injury.
NOTE
THIS MOTOR IS TO BE SERVICED ONLY BY
AUTHORIZED TDI TURBOTWIN™ DISTRIBUTORS,
DEALERS, AND REPAIR STATIONS. DO NOT
OPERATE THIS MOTOR UNLESS IT IS PROPERLY
INSTALLED ON AN ENGINE.
2.0 ORIENTATION OF THE
MOTOR
The factory orientation of the motor’s
mounting flange is ideally configured for
most applications and does not required
reorientation.
2.1 MODEL T30-I ORIENTATION
Determine the required orientation of the
optional exhaust port if installed.

2.1.1 Exhaust Housing Orientation
If this unit has an optional exhaust housing
remove the seven (if a 90⁰elbow) or eight (if
a straight exhaust) socket head cap screws
connecting the exhaust to the turbine
assembly. Rotate the exhaust housing to
the desired position relative to the inlet port.
Reinstall the seven or eight socket head cap
screws. Torque to 61 Lbs.-In. (6.89 Nm)
CAUTION
Ensure the O-ring on the exhaust housing
remains in position and is not cut.
3.0 INSTALLING THE MOTOR
The T30ML air motor is configured with a
footed section on the gearbox housing for
installing onto the engine or appropriate
mounting bracket. The air motor and
optional 7 or 30 GPM oil pump if attached to
motor should be mounted in a horizontal
position as shown.
The piping illustrated may vary in shape, but
there must at least be a start initiation
switch, air supply, and a motor relay valve to
correctly install and operate a T30 Series
motor.
NOTE
Installing the air piloted relay valve on the
motor is preferred in installations where the
space is available.
TDI recommends mounting the air piloted
relay valve no more than 3 meters (10 feet)
from the motor’s inlet port, and as close to
the motor as possible. If the motor is being
installed on a vehicle where the air tank is
within 3 meters (10 feet) of the motor, then
the relay valve may be mounted on the tank.
A turbine driven motor does not require
lubrication in the supply air. Therefore, if a
vane-type motor is being replaced, TDI
recommends that all lubrication devices and
lines be removed to minimize flow
restrictions.
WARNING
If a fuel (pulse) lubricator is installed in the
system, disconnect and plug the line to
eliminate spraying diesel fuel on the
engine.
After mounting the motor to the engine,
attach the supply air line from the tank
including any control air lines, air piloted
relay valve and solenoids.
TDI recommends installation of a “Glad
Hand” / quick disconnect for auxiliary
pressurization of the air tank.
Because turbine motors are sensitive to flow
restrictions, care must be taken to use
uniform sized hose or tubing and fittings for
connection of the supply air line. Tees,
elbows, and line length must be kept to a
minimum.
TDI recommends that hose or flex couplings
be installed to eliminate possible leakage
caused by strain on the supply air line.
Normally an air strainer is not required. In
dirty environments, use of a #40 mesh
Y-strainer is recommended.

Only type approved metallic hose
assemblies are approved in permanently
pressurized compressed air lines of motors.
Non-metallic hose assemblies are allowed
only in case the piping system will be
emptied after the starting procedure.
Pipe unions must be type approved by GL.
Downstream of the pressure regulator a
pressure relief valve is to be provided.
WARNING
Recheck all connections for tight fit to
eliminate leakage.
Fill the air system tank. The T30 Series
motor is now ready to operate.
4.0 MOTOR OPERATION
The maximum operating pressure limit is
that pressure measured at the motor inlet
pressure check port during the run cycle. In
order to check the motor inlet pressure, a
1/8" NPT pipe tap connection is provided
just below the main inlet for attaching a
pressure gauge. Refer to Figure 1. IN NO
CASE SHOULD INLET OPERATING
PRESSURE EXCEED 10.3 BAR (150
PSIG).
WARNING
Do not operate the TDI TurboTwin T30
Series air motor with air pressure greater
than the pressure rating on the nameplate.
This pressure should be measured at the
motor inlet while the motor is operating.
The static supply pressure will always be
higher than the operating pressure. As a
guideline, the maximum pressure limit (proof
pressure) that the T30 Series motor may be
subjected to is 600 PSIG (41.4 Bar).
System pressure that exceeds the maximum
operating limit must use a pressure regulator
to ensure operating pressure limit to the T30
Series motor is maintained.
System pressure that exceeds the 600 PSIG
(41.4 Bar) limit must, in addition to a
pressure reducer device, incorporate a
pressure relief valve, set below 600 PSIG
Bar (41.4) in the supply air line.
All appropriate local pressure codes and
pressure limitations on other system
components must be adhered to and
supersede guidelines given in this manual.
If the motor fails to function properly when
first operated, or its performance
deteriorates with use, refer to the Operator’s
Trouble Shooting Guide, Section 6.0. If you
cannot solve the problem, or repair is
necessary, contact your local TDI
TurboTwin™ distributor or dealer.
CAUTION
The grease used in the planetary system
has a shelf life of 2 years. Therefore, if the
motor is NOT installed and operated on the
engine for 2 years after the motor is
manufactured, the grease should be
replaced prior to motor operation. The
manufactured date is reflected in the motor
serial number. (Ex: 0602-0567 has a
manufactured date of February 2006).
