Pow-R-Quik PRQ–LS23/LS24 Air Starter


LS-23/24 Model Vane Air Starter

The LS 23/24 Series air starter available at Strumco Air Starter is a gear reduction gas sealed starter that will start diesel engines up to 1,500 CID. It will start twice the CID if used on a gas engine due to the lower compression ratio.

Inertia Drive (Friction Clutch)For engines up to 1,500 CID (24.5 liters) diesel and 3000 CID (49 liters) carbureted.



  • Stainless Steel Rotor Casing
  • Sealed Thrust Bearings
  • High Tech Vanes

It is a lubeless starter that incorporates teflon ™ filled rotor blades running in a stainless steel cylinder using teflon ™ coated end plates.

Lubrication may be added to the airstream as long as it is not a high base or penetrating oil that has solvents that can delaminate the rotor blades.

The LS 23 and LS 24 air starters are identical with the exception of the gear ratios. The LS 23 air starter has a 2.81:1 ratio while the LS 24 air starter has a lower 3.36:1 ratio; the 24 air starter will deliver more torque than the 23 air starter  but has a some what slower top pinion speed.

The LS 23 air starter available at Strumco Air Starter is recommended for most engines in its range with the LS 24air starter being used only at the upper limits of the range or where there is excessive parasitic load that cannot be uncoupled from the engine.

The LS 23/24 air starters incorporate a heavy duty friction drive to engage the ring gear. A pre-engaged version of the LS 23/24 air starter  is available at Strumco Air Starter .The pre-engagement requires additional air lines that pneumatically push the starter drive into the meshed position. A return spring de-meshes the drive from its ring gear when the air source is removed upon completion of the engine start cycle.
