SS815GB03R31 (3 IN STOCK TODAY) Vane Air Starter by Ingersoll Rand

The Ingersoll Rand SS815GB03R31 is a genuine IR SS800-series pre-engaged vane air starter. It produces up to 75 hp (56 kW) and 250 ft-lb (339 N·m) of breakaway torque at 150 psi, and IR rates it for diesel engines from 16 to 130 liters. It bolts to an SAE No. 3 flange and drives the ring gear through a 12-tooth, 6/8 pitch, right-hand pinion with 2.18:1 "B" gearing. Because it is gas sealed, it runs on compressed air or natural gas. Common applications include Caterpillar 3500, Cummins K38/QSK, Detroit Diesel 149 and MTU 2000/4000 engines, as well as Waukesha gas compressor engines.

Performance by Supply Pressure

Cranking performance depends on the pressure you supply. Ingersoll Rand publishes these figures for the SS815:

Source: Ingersoll Rand Engine Starting Systems catalog, SS800 Series performance information. Some older IR selection guides round the SS815's maximum output to 80 hp.

Engine builders change ring gears and starter pads between serial ranges, so please confirm the ring gear tooth count, pitch and rotation before you order. You can look up your engine in our Air Starter Model Finder, or call us with the engine model and serial number.

Why Choose the SS815 Vane Starter?

• High torque at low speed. The vane motor delivers its best torque at lower rpm than a turbine. Lower speed is easier on bearings and needs less planetary gear reduction.
   
• Pre-engaged drive. The pinion is fully in mesh before cranking begins. This reduces milling of the ring gear and pinion, which matters on heavy, high-compression engines.
   
• No sparks, no batteries. A pneumatic starter has no electrical arcing, so it suits hazardous areas on offshore platforms, gas compression sites and refineries. It also does not lose cranking power to cold batteries.
   
• Runs on air or natural gas. The gas-sealed housing lets you use pipeline gas where compressed air isn't available.
   
• Easy to install and service. Thanks to the offset design and the clockable inlet, exhaust and drive housing, one starter fits many engine layouts. It can be serviced in the field with the SS800-TK2 kit.

SS815GB03R31 FAQ

What is the difference between the SS815GB03R31 and the SS815GB03L32?

Only the rotation and pinion differ. The SS815GB03R31 has a right-hand rotation and the code 31 pinion. The SS815GB03L32 has a left-hand rotation and the code 32 pinion, which is the left-hand version of the same 12-tooth, 6/8-pitch pinion. Power, flange and gearing are the same.

What is the difference between the SS810, SS815, SS825 and SS850?

All four use the same 75 hp SS800 vane motor. The SS810 is an inertia-engagement starter. The SS815 (B ratio, 2.18:1) is pre-engaged and covers diesel engines from 16 to 130 L. The SS825 (C ratio, 2.53:1) is pre-engaged and covers 80 to 200 L. The SS850 (D ratio, 3.44:1) has an "09" flange and covers 160 to 320 L. Compare the full SS800 series.

Can the SS815GB03R31 run on natural gas?

Yes. The "G" in the model number means the starter is gas sealed, so it can run on compressed air or natural gas. When you run it on gas, pipe the exhaust away to a safe location as required by your site's codes.

Is the SS815 suitable for long cranking cycles?

IR does not rate the SS815 for extended starting capability (cranking longer than 10 seconds). For hard-starting engines, cold climates or applications that need long crank cycles, step up to the next larger starter. Another option is a turbine starter such as the ST2060B03R31, which uses the same SAE 3 flange and 31 pinion.

What air supply does the SS815GB03R31 need?

You need a 90 to 150 psi supply delivered through a line no smaller than the 1-1/2 in. inlet, with enough receiver volume to supply up to 1,700 scfm while the engine cranks. Keep the supply line short, add a lubricator and an inlet strainer, and use a properly sized relay valve. Higher pressure gives more torque and speed, as shown in the performance table above.

What replaces the ASC 1815 or other SS800 copies?

The ASC 1815 (1815FGB03R31) and other aftermarket SS815-pattern starters copy the Ingersoll Rand SS815 design. ASC publishes the SS815GB03R31 as the crossover for its right-hand 1815, so it is a direct path back to genuine Ingersoll Rand equipment.
