SS350GB03R77 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: SS350GB03R77-02H.

Why Choose the SS350GB03R77?

• Compact and powerful. A 36 hp vane motor in a 33 lb package for 8 to 27 L engines.
   
• Pre-engaged drive. The pinion is fully in mesh before cranking begins, which reduces ring gear wear.
   
• Runs on air or natural gas. The SS350G is gas sealed.
   
• No sparks, no batteries. No electrical arcing and no dependence on battery condition.
   
• Two gearing choices. B gearing (2.18:1) favors speed; E gearing (3.46:1) gives more breakaway torque for harder-to-turn engines.

SS350GB03R77-01D FAQ

What is the opposite-rotation version of the SS350GB03R77-01D?

The SS350GB03L32-02H 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 B and E gearing?

E gearing (3.46:1) delivers more breakaway torque at lower speed (160 ft-lb at 150 psi) than B gearing (2.18:1, 110 ft-lb). Both give 36 hp at 150 psi. Choose the ratio your engine was specified with.

Can it run on natural gas?

Yes. The "G" means the starter is gas sealed. Pipe the exhaust away to a safe location when running on gas.

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 an SS800 or a turbine starter.

What air supply and accessories does it need?

Provide a 90 to 150 psi supply through a 1-1/4 in. line, with enough receiver volume to deliver up to 900 scfm while the engine cranks. Ingersoll Rand's matching accessories include SRV100 or SRV125 relay valve, ST1000-267-24 strainer, 150BMP-1051B (12 V) or 150BMP-2451B (24 V) solenoid valve, SS350-A674 muffler.

Is there a lube-free alternative?

For smaller engines, Ingersoll Rand's lube-free SS100 covers engines up to 10 L. For turbine starters in this size, see the ST400 series.
