1. There is a natural gas vent port in the turbine housing that is plugged for compressed air use This vent is used to remove any natural gas that could leak past the primary turbine shaft seal Remove this 3 8 NPT plug and install a line to carry gas away from the starter area WARNING Do not connect the turbine housing vent line to the turbine exhaust line Exhaust gas can pressurize the housing 3 5 PIPING SYSTEM Only type approved metallic hose assemblies are approved in permanently pressurized compressed air lines of starters Non metallic hose assemblies are allowed only in case the piping system will be emptied after the starting procedure Publication T1 702 Rev 1 Issued January 22 2001 Pipe unions must be type approved by GL Downstream of the pressure regulator a pressure relief valve is to be provided 3 6 BACKLASH Backlash is the free play between the mesh of two gears Figure 15 shows the backlash between two gears Maintaining the proper gear backlash setting allows the gears to mesh smoothly Proper backlash and alignment allows smooth engagement disengagement of the pinion gear and loads the tooth face surfaces evenly producing longer gear life The correct backlash setting for 6 8 diametral pitch gearing used on larger engines is as follows 015 inch 025 inch Minimum backlash Maximum backlash To check the backlash the pinion will need to be rolled out onto the end of the drive prior t2. 1 1 DESCRIPTION All models feature three basic subassemblies a unique two stage turbine motor section a planetary gearbox section and an inertia drive assembly The two stage motor section features greater stall torque than a single stage turbine plus aerodynamic speed control Page 2 This aerodynamic speed control helps protect the TURBOTWIN starter from damage caused by starter motor over speed The T100 TURBOTWINS employ a 7 5 1 or 9 1 ratio planetary gearbox This low gear ratio allows the turbine motor to spin at low speeds for long bearing life typical 3000 rpm pinion speed the turbine is cruising at a low 22500 rpm 7 5 1 ratio Reliability and part commonality are designed into all TURBOTWINS A simple and reliable inertia drive delivers the torque to the pinion The pinion is thrown out to engage the engine s ring gear by the turbine motor s acceleration Lighter weight rotating parts used in the TURBOTWIN provide low inertia and even softer engagement In the event of over pressure the friction clutch used in every TURBOTWIN protects ring gear teeth from static torque overloads In addition an inertia engaged starter eliminates the need for complex pre engagement control plumbing and is easier to install and maintain than pre engaged type starters Compressed air or natural gas is used to power T100 TURBOTWIN air starters through the inlet port The air or gas is expanded through the first nozzle or stat
3. line length must be kept to a minimum TDI recommends that hose or flex couplings are installed to eliminate possible leakage caused by strain on the supply line Normally an air strainer is not required However in dirty environments use of a 40 mesh Y strainer is recommended The T100 TURBOTWIN series is highly tolerant of dirt in the air line however starter life can be increased with the use of an air strainer TDI TURBOTWIN rrom TECH DEVELOPMENT INC A pressure regulator is required when the air supply pressure is great enough to exceed the starter operating pressure at the inlet port and or the maximum torque A manual ball valve may be used to admit drive air gas to the starter The manual valve should be located in a safe position away from the engine A preferred valve is pilot operated which can be pneumatically or electrically actuated The valve should be located close to or even on the starter inlet for best performance Pneumatic or electrical control lines may be routed virtually anywhere for the customer s preferred operating station This type of valve actuates from a fully closed to a fully open position very rapidly TDI offers a variety of relay valves such as P N RLVA 25683 001 2 01 which is a 1 1 2 port pneumatically actuated valve The supply line should be dry fitted for proper alignment location prior to final assembly All pipe threaded joints should be sealed with Loctite Pipe Thread Sea

OTWIN models are turbine driven starters with an inertially engaged starter drive Depending on the starter model and engine installation the TURBOTWIN starters have applications ranging from 1200 CID 20 Liters on diesel engines and up to 15000 CID 250 Liters on gas engines The TURBOTWIN 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 starting The T100 TURBOTWIN 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 stream will not adversely affect TURBOTWIN starters As with all other TDI starters no lubrication is required in the air supply Please review the rest of this manual before installing the T100 TURBOTWIN series 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 likely 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 other wise stated air means either compressed air or natural gas
