Description
The Ingersoll Rand ST799GCDP03L942 is a genuine IR ST700-series pre-engaged turbine air starter. It delivers up to 66 hp (49 kW) at 90 psi, 360 ft-lb of breakaway torque, and Ingersoll Rand rates C-ratio ST700/ST900 starters for diesel engines from 80 to 200 liters. It has a full-arc (30 to 90 psi) turbine sealed for gas and air, an SAE No. 3 flange and a left-hand code 942 pinion. Ingersoll Rand's current replacement in this size is the ST1000 series.

ST799GCDP03L942 Orientations and Builds
This starter is also listed in these orientations and configurations. The motor, gearing, flange and pinion are the same; the suffix sets the inlet, exhaust and drive-housing positions or marks a special build: ST799GCDP03L942-3P.
Why Choose the ST799GCDP03L942?
- High torque, broad range. B and C gearing options cover a wide range of starting torques.
- Lube-free turbine. No lubricator and no oil mist; sealed planetary gears are maintenance free.
- Air or natural gas. Sealed for gas and air applications.
- Proven design. The ST700/900 turbine family has powered diesel and gas engines in marine, oil and gas, locomotive and power generation service.
- Current replacement available. Ingersoll Rand's ST1000 series is the direct successor.
ST799GCDP03L942 FAQ
What is the opposite-rotation version of the ST799GCDP03L942?
The ST799GCDP03R25-P0S is the opposite-rotation counterpart. Power, flange and gearing are the same; only the rotation and the matching pinion code differ. Match the rotation printed on your existing starter's nameplate.
Is this starter still available, and what replaces it?
Ingersoll Rand's ST1000 series supersedes the ST700 and ST900 (the ST750 and ST950 go to the ST1060, and the ST799 and ST999 go to the ST1099, with the same ratio, drive, flange and pinion). Call us and we will confirm current availability of the ST799GCDP03L942 and quote the ST1000 alternative side by side. See the ST1000 series.
Can it crank for a long time?
Ingersoll Rand does not rate the ST750 and ST799 for extended cranking (more than 10 seconds). If your engine needs long crank cycles, choose an ST900-series or ST1000-series starter.
What air supply and accessories does it need?
Supply 30 to 90 psi through a 1-1/2 in. line, with enough receiver volume to deliver up to 1,700 scfm while the engine cranks. Ingersoll Rand's matching accessories include the SRV150 relay valve (SRV150SS for gas), the ST900-267-24 1-1/2 in. strainer (300 mesh), 150BMP-1051B / 150BMP-2451B solenoid valves and SMB-618 / SMB-G618 push-button valves.

Ingersoll Rand pneumatic air starters can replace any factory mounted starter engine and simultaneously offer a variety of helpful benefits. Compared to conventional electric starters, a pneumatic air starter occupies considerably less space as it is run by air. Pneumatic air starters are also considered safer in hazardous environments as they do not produce electrical sparks like electric starters sometimes do, thus eliminating the risk of igniting flammable materials that may be present.
Ingersoll Rand air starters have significantly more torque than electric starters of equivalent size, and that allows even a small air starter to start very large engines and turbines. In addition, electric starters as well as their wiring may become excessively hot in the event that it takes longer than expected to start the engine, while air-starters can be run for as long as their air supply lasts. Turbine starters provide even more torque and tend to be simpler, and therefore are a natural fit for turbine engines. Turbine air starters are utilized extensively on large turbofan engines commercial and military aircraft; as well as marine ships and vessels, trains, heavy construction equipment, and more.
