1.0 GENERAL INFORMATION
This manual provides instructions for the installation and
operation of the TDI
T100-VE T
URBO
T
WIN
Air Starters. If
there are questions not answered in this manual, please
contact your TDI
T

distributor or dealer for
assistance.
The T100-VE starters are turbine driven starters with a
pre-engaged starter drive. The
T100-VE
starters have
applications ranging from 1800 CID (30 Liters) on diesel
engines and up to 18000 CID (300 Liters) on gas
engines. The
T100-VE
models are suited to operate
within a wide range of inlet pressures and ambient
temperatures. The engine size and parasitic loading will
determine the exact minimum pressure that will assure
reliable cranking.
The
T100-VE
starters are designed for operation with
compressed air or natural gas; materials used are
compatible with “sour” natural gas and marine
environments. Small amounts of foreign matter or liquid
in the air supply will not adversely affect
T100-VE
starters. As with all TDI starters, no lubrication is
required in the air supply.
Please review the rest of this manual before installing
the
T100-VE
air starter.
WARNINGS, CAUTIONS, AND NOTES
Certain types of information are highlighted in this
manual 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.
NOTE
Throughout this manual, the term “air” is used to
designate the starter drive medium. Unless otherwise
stated, “air” means either compressed air or natural gas.
1.1 DESCRIPTION
The T100-VE features three basic subassemblies: a
unique two stage turbine motor section, an offset/spur
gear assembly and a pre-engage drive assembly.
The two stage motor section features greater stall torque
than a single stage turbine plus aerodynamic speed
control. This aerodynamic speed control helps protect
the
T100-VE
starter from damage caused by starter
motor over speed. In addition, a specially designed
motor housing module and low-mass rotors provide fail-
safe operation.
The
T100-VE
employs 9.25:1 ratio spur gearbox. This
low gear ratio allows the turbine motor to spin at low
speeds for long bearing life. At a typical 3000 rpm pinion
speed, the turbine is rotating at a low 27750 rpm.
A reliable pre-engaged drive delivers the torque to the
pinion. The pinion is translated out to engage the
engine's ring gear via the starter’s engagement piston.
Compressed air or natural gas is used to power the
T100-VE
through the inlet port. The air or gas is
expanded through the first nozzle or stators. The high
velocity gas impinges on the first stage rotor to yield
torque to the gearbox through momentum exchange.
The gas is further directed through the second stage
stators which impart additional torque to the second
stage rotor.
1.2 PRODUCT IDENTIFICATION
The starter nameplate which is attached to the turbine
housing contains the following information: model
number, serial number, part number, direction of rotation
and the maximum rated operating pressure.
The directions of rotation are either right hand or left
hand rotation as shown in Figure 1. Right Hand rotation
is defined as clockwise rotation as viewed from the
pinion end of the starter, and Left Hand rotation is
counter clockwise rotation viewed from the pinion end of
the starter.
