The drive air pressure is the primary starter control 
parameter

It is important, especially on new 

installations, to measure this pressure during several 
engine starts. The secondary parameter is the starter 
pinion speed. This speed is usually measured by 
knowledge of the engine starting speed and the starter 
cranking ratio. The cranking ratio is the number of ring 
gear teeth divided by the number of pinion teeth. The  
 
starter pinion speed is then found by multiplying the 
engine speed by the cranking ratio. The pinion speed is 
usually 2000-3500 rpm at typical engine starting speed. 
 

4.2 AUTOMATED START PANEL

 

 
The starter drive pressure measured at the starter inlet 
will need to be set.   As noted above, for maximum life of 
the starter pinion and for the protection of the engine ring  
gear, limit the operating pressure to that necessary to 
start the engine at its most difficult starting conditions. 
 
The speed control parameter will then need to be set. 
Engine starting speed along with the cranking ratio 
number can be used to determine starter pinion speed. 
The pinion speed is usually 2000-3500 rpm for a typical 
engine starting speed. Once the start sequence has 
begun, the air is admitted to the starter. The starter 
begins to accelerate the engine. Once the firing speed of 
the engine is reached, the automated start panel may 
deliver fuel to the engine. The engine will begin to 
accelerate under its own power. The starter should be  
 

 
dropped out of the sequence at an rpm higher than the 
firing speed, but less than the engine idle speed. 
The automated start panel should monitor engine speed 
to determine air on and air off.  Do not simply use time 
as a control parameter. Avoiding excessive operation of 
the starter after the engine is firing will maximize the 
starter life. 
 

4.3 BEST OPERATING PRACTICES 

 

 To extend starter life, apply only the minimum 

pressure required, to successfully crank & start 
the engine. 

 

Never exceed starter maximum operating 

pressure identified on starter nameplate.  This 
pressure can be best measured dynamically 
while starter is running. 

  For longer starter life, operate (or design controls) 

to shut off supply pressure to the air starter 
immediately after a successful engine start. 

  If engine fails to start or stalls, wait at least 15 

seconds before attempting to re-start to allow 
the starter to coast to a complete stop. 

 Never re-engage pinion into ring gear when 

starter is coasting down as this may damage the 
starter pinion gear and engine ring gear.  

  Never engage starter while engine is operating as 

this may damage the starter, the pinion gear, 
and engine ring gear.
