INGERSOLL-RAND KVG OEM Air Starter Replacement /Upgrade

Ingersoll Rand air starters for the Ingersoll-Rand KVG. The Ingersoll-Rand KVG is a 6-cylinder gas engine of 322.8 liters (19,700 cu in). Our Air Starter Model Finder, built from Ingersoll Rand application data, recommends 2 x ST1060CP03R25, an ST1000 series turbine starter, working together with a right-hand pinion (11 teeth, 6/8 pitch). The finder lists 4 starter configurations for this engine; all are shown below.

Why These Starters Fit

Ingersoll Rand rates one ST1060CP03R25 for diesel engines up to 320 L. At 322.8 L, the KVG gets 2 starters cranking together, which is how large engines are commonly started.

Ingersoll Rand's catalog rates its starters for carbureted gas engines of roughly twice the diesel displacement (for example, the ST1000 covers diesel engines from 16 to 320 L and carbureted gas engines from 32 to 660 L), so a gas engine is well inside the rating that suits a diesel of the same size.

Flange, Rotation and Pinion

Rotation: right-hand. Pinion: code 25, 11 teeth, 6/8 pitch, 20° pressure angle.

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 ST1060CP03R25 runs on 30-150 psi and uses 1290 scfm (609 L/s) at maximum power. It is rated for compressed air or natural gas. The Model Finder pairs it with the ST1000-267-24 inlet strainer, which keeps scale and debris out of the motor.

Ingersoll-Rand KVG Air Starter FAQ

What air starter fits the Ingersoll-Rand KVG?

The Model Finder recommends 2 x ST1060CP03R25. Alternatives are 2 x ST1060CP03R, 2 x ST950CP. Confirm the flange, rotation and pinion against your current starter before ordering.

Why does the recommendation list more than one starter?

On engines this large, the starting torque needed is above what one starter of this size delivers, so 2 starters are mounted on the flywheel housing and engage together. Your engine's flywheel housing must have a mounting pad for each one.

Can the ST1060CP03R25 run on natural gas?

Yes. Ingersoll Rand rates the ST1060CP03R25 for compressed air or natural gas. On gas, pipe the exhaust away to a safe location.

Can I replace an electric starter on the KVG 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.
