SS850GD09R51 Vane Air Starter by Ingersoll Rand

The Ingersoll Rand SS850GD09R51 is a genuine IR SS800-series pre-engaged vane air starter. It delivers up to 75 hp (56 kW) and 415 ft-lb (562 N·m) of breakaway torque at 150 psi, and Ingersoll Rand rates the SS850 for diesel engines from 160 to 320 L. It has 3.44:1 "D" gearing and an IR "09" flange, and it drives a right-hand 15-tooth 6/8 pitch pinion. The gas-sealed housing runs on compressed air or natural gas.

How to Read the Model Number

Why Choose the SS850GD09R51?

• Powerful and rugged. A 75 hp vane motor in the large-frame SS800 design that Ingersoll Rand calls the standard by which other starters are measured.
   
• Pre-engaged drive. The pinion is fully in mesh before cranking begins, which reduces ring gear wear on heavy engines.
   
• Runs on air or natural gas. Every SS800 model is gas sealed.
   
• No sparks, no batteries. A pneumatic starter has no electrical arcing and does not lose power to cold batteries, so it suits marine, oil and gas, mining and standby power service.
   
• Flexible mounting. The 4 inlet x 4 exhaust x 16 drive-housing orientations let one starter fit many engine layouts, and the starter is field serviceable.

SS850GD09R51 FAQ

What is the opposite-rotation version of the SS850GD09R51?

The SS850GD09L52 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.

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 starter; the SS815, SS825 and SS850 are pre-engaged. Gearing sets the engine size: SS810 and SS815 use B gearing (diesel 16 to 130 L), the SS825 uses C gearing (80 to 200 L) and the SS850 uses D gearing (160 to 320 L). Compare the full SS800 series.

Can it run on natural gas?

Yes. The "G" in the model number means the starter is gas sealed. When running on gas, pipe the exhaust away to a safe location as required by your site's codes.

Can it crank for a long time?

Ingersoll Rand does not rate this starter for extended cranking (more than 10 seconds). For hard-starting engines or long crank cycles, step up to a larger SS800 model or choose a turbine such as the ST1000 series.

What air supply and accessories does it need?

Provide a 90 to 150 psi supply through a 1-1/2 in. line, with enough receiver volume to deliver up to 1,275 scfm while the engine cranks. Ingersoll Rand's matching accessories include SRV125 or SRV125T relay valve, ST900-267-24 strainer, 150BMP-1051B (12 V) or 150BMP-2451B (24 V) solenoid valve, SS800-A674 muffler.
