Recommended Starters for the Ajax DPC60

Why These Starters Fit

Ingersoll Rand rates the ST150 for diesel engines up to 90 L, so the 14 L DPC60 sits within its range.

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.

You can choose between turbine and vane designs. The ST155FP88L54 turbine starter delivers up to 47 hp (35 kW) at 150 psi, uses 905 scfm (427 L/s) at maximum power and runs on 60-150 psi. By comparison, the 150BMGE21LH-11 vane starter delivers up to 32 hp (24 kW) at 150 psi, uses 680 scfm (321 L/s) at maximum power and runs on 90-150 psi.

Flange, Rotation and Pinion

Flange: SAE No. 3. Rotation: left-hand. Pinion: code 54, 11 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 ST155FP88L54 runs on 60-150 psi and uses 905 scfm (427 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.

Ajax DPC60 Air Starter FAQ

What air starter fits the Ajax DPC60?

The Model Finder recommends the ST155FP88L54. Alternatives are 150TLPF88L54, 150BMGE21LH-11. Confirm the flange, rotation and pinion against your current starter before ordering.

Can the ST155FP88L54 run on natural gas?

Yes. Ingersoll Rand rates the ST155FP88L54 for compressed air or natural gas. On gas, pipe the exhaust away to a safe location.

Can I replace an electric starter on the DPC60 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.
