NOTE
TDI recommends synthetic grade oil (turbine oil) is
used in the starter gearbox sump. Use of either
improper synthetic or mineral based oils may
compromise unit service life, manufacturer’s warranty,
and will increase the frequency of maintenance
intervals required.
WARNING
Do not operate this starter unless gearbox has been
filled to the proper oil level and maintained at this
level.
WARNING
Do not operate this starter unless it is properly
connected to an engine or load (see below).
2.2 SUPPLY LINE & EXHAUST LINE
INSTALLATION
WARNING
Be sure to either bleed the pressurized air reservoir
and/or safety the system such as closing all air/gas
supply valves, prior to installing motor or a new
supply line.
T100 TURBOTWIN T100-MS
starter motors come
standard with a 2" NPT female pipe thread adapter for
the inlet connection port & various 3” exhaust adapters.
Various flange or thread adapters may be utilized at
these joints. Supplied adapters are sealed to the
motor housing with Viton O-rings (see section 2.1).
Hard piping may be used on supply/exhaust lines. A
section of flexible tubing may also be use/installed at
the starter inlet/outlet, to prevent leaks or wobble out
due to vibration.
The supply line consists of the line from the air/gas
supply source (via a pressure regulator when
necessary) through filters, manual and/or automatic
relay valves, to the starter
inlet.
The exhaust line consists of the line from the motor
exhaust to a “safe” location. Turbine exhaust (air) is
typically plumbed away from the engine area.
Both supply & exhaust lines and components should
be dry-fitted for proper alignment /location, prior to final
assembly.
All pipe threaded joints should be sealed with Loctite
Pipe Thread Sealant (TDI P/N 9-94085) or equivalent,
for leak tight joints prior to final assembly. Be sure to
tighten all joints to proper torque after final assembly.
The installation of the motor using natural gas is similar
to the air installation except all fittings, piping, valves
and regulators must be compatible with natural gas.
WARNING
When using natural (or combustible) supply gas
(e.g. methane gas) must be piped to a safe location,
routed and terminated according to industry codes
and local regulations.
NOTE
If the supply line is longer than 40 feet, the line piping
size may need to be increased to 2" diameter, to
minimize dynamic flow losses through piping and
ensure specified output. Similarly, if exhaust piping is
longer than 40 ft. in length, it may be necessary to
increase its diameter from 3” to 4” to minimize motor
exhaust back pressure and insure specified output.
On T115-MS applications, valves or regulators on the
supply side, having a
Cv of 40
or higher, are
recommended for starter having 15 nozzles (T115-MS)
Care must be taken to insure all inlet supply line piping
& components are capable of passing the required air
flow needed to produce specified power levels (motor
output).
See motor performance chart for specific
flow rates.
WARNING
Be sure that any/all piping &/or tubing used, meets
applicable requirements and that no leaks are
present following line installation or thereafter.
CAUTION
Although the light weight of these motors is easily
supported by their mounting flange designs, TDI
recommends properly bracing all rigid piping attached
to the motors… to eliminate axial strain on motor &
motor mounting flanges. High axial loads (“over-hung
bending”) will greatly reduce motor life.
