Ingersoll Rand Engine Starting Systems Air Starter Catalog (Form 51600-C)
A 1997 Ingersoll-Rand product catalog covering its full line of vane and turbine air starters for diesel and spark-fired engines, from the small 3BMG up to the ST950/ST999 large-frame turbines. It is aimed at buyers, engine builders and service shops choosing or replacing a starter. Each series gets a page of features, accessories, pinions and model coding plus a page of dimensions and performance curves, followed by system accessories, typical installation schematics, tune-up and seal kit diagrams, and cross-reference tables from superseded models.

Piping a multiple ST700/ST900 starter installation (Overview)
- Size the supply line from the pipe-size chart so operating pressure holds at the starters while they all run, never above the nameplate maximum.
- Give each starter its own SRV150 relay valve and ST900-267 strainer, fed through a 1-1/2" hose.
- Seal every pipe connection with sealant.
- For natural gas operation, pipe the main starter exhaust away.
- To pipe the drive housing vent, replace the plug with tubing that vents at a safe spot and is not tied into other exhaust lines.
An outline only. Follow the full procedure, torque values and safety warnings in the document (from page 56).
Frequently Asked Questions
Which Ingersoll Rand air starter fits a 16 to 130 liter diesel engine?
The selection guide lists the SS810G and SS815G vane starters and the ST750G and ST799G turbine starters for this range. The ST750/ST799 GBI (inertia) and GBDP (pre-engaged) versions are both rated for 1000 to 8000 CID diesels.
What is the difference between a pre-engaged and an inertia air starter?
In a pre-engaged starter the pinion is fully meshed with the ring gear before cranking begins. In an inertia starter the spinning pinion engages the ring gear at the same moment cranking starts.
How do I adjust the selection guide for 2-stroke diesel or gasoline engines?
The catalog says the displacement figures can be multiplied by 1.5 for 2-stroke diesels and doubled for carbureted gas engines. Torque values shown are stall torque; starting torque is about 75% of them, and hard-starting engines should get the next larger starter.
Can the ST400I turbine starter run on natural gas?
No. The ST400I is marked for air use only, and the crossover guide notes the ST400I series is not for use with natural gas.
Which relay valve goes with which starter series?
SRV100 (1" NPT) serves 3BMG, 5BMG and SS175G; SRV125 (1-1/4") serves 150BM and SS350G; SRV150 or the stainless SRV150SS (1-1/2") serves SS800, ST700 and ST900; SRV125T is for 150BMP air-only starters.
