Description

Description

Ingersoll Rand air starters for the Detroit Diesel 3-71. The Detroit Diesel 3-71 is a 3-cylinder diesel engine of 3.5 liters (213 cu in). Our Air Starter Model Finder, built from Ingersoll Rand application data, recommends the ST400C03R31, an ST400 series turbine starter, on an SAE No. 3 flange with a right-hand pinion (12 teeth, 6/8 pitch).

Recommended Starters for the Detroit Diesel 3-71

Choice	Ingersoll Rand starter	Type	Supply pressure	Max power	IR diesel rating
Turbine option	ST400C03R31	ST400 series turbine	90-150 psi	25 hp (19 kW) at 150 psi	Up to 60 L
Vane option	SS175GB03R31	SS175 series vane	90-150 psi	18 hp (13 kW) at 150 psi	Up to 10 L

Why These Starters Fit

Ingersoll Rand rates the ST400 for diesel engines up to 60 L, so the 3.5 L 3-71 sits within its range.

You can choose between turbine and vane designs. The ST400C03R31 turbine starter delivers up to 25 hp (19 kW) at 150 psi, uses 750 scfm (354 L/s) at maximum power and runs on 90-150 psi. By comparison, the SS175GB03R31 vane starter delivers up to 18 hp (13 kW) at 150 psi, uses 500 scfm (236 L/s) at maximum power and runs on 90-150 psi.

Flange, Rotation and Pinion

Flange: SAE No. 3. Rotation: right-hand. Pinion: code 31, 12 teeth, 6/8 pitch.

Engine builders change flywheel housings, ring gears and rotation between applications and serial ranges, so match the flange, rotation and pinion on your existing starter's nameplate before you order.

Air Supply

The ST400C03R31 runs on 90-150 psi and uses 750 scfm (354 L/s) at maximum power. It is rated for compressed air only. The Model Finder pairs it with the ST1000-267-24 inlet strainer, which keeps scale and debris out of the motor.

Detroit Diesel 3-71 Air Starter FAQ

What air starter fits the Detroit Diesel 3-71?

The Model Finder recommends the ST400C03R31. Alternatives are SS175GB03R31. Confirm the flange, rotation and pinion against your current starter before ordering.

Can the ST400C03R31 run on natural gas?

No. Ingersoll Rand rates the ST400C03R31 for compressed air only. The SS175GB03R31 vane option is rated for air or natural gas.

Can I replace an electric starter on the 3-71 with an air starter?

Air starters mount on standard SAE flanges, so they are often used in place of electric starters where batteries, sparks or cold starts are a concern. See air vs. electric starters, and call us with your engine serial number so we can confirm the flange, pinion and air supply.

How do I confirm the right starter?

Send us the full model number from your existing starter's nameplate, or the engine make, model and serial number. Engine builders change ring gears and flywheel housings between serial ranges, so we confirm fit before quoting.

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.
