I am looking for a dimension from the propeller mounting surface of the engine, to the back edge of the spinner.  I am attempting to mount the cowl (James Cowl) without the prop or spinner in hand, and need this dimension to set the jig used to hold the cowl at the proper dimension from the face of the crank.  There is a rather long lead time on the prop, and I would like to get the cowl positioned so I can continue mounting the plenum, ram air, etc.  If anyone has the Hartzell 14" spinner (A-2297), and the 'standard' Hartzell 2-Blade Blended Airfoil Prop (C2YR-1BFP/F8068D) on hand, I would greatly appreciate any help.  I received some numbers from Hartzell, but am not confident enough to start cutting (they told me .99").  Others have told me that number doesn't seem right, but do not have data one way or the other. 



 Thanks, Jason [quote][b]

Jason. 



I have the same prop but with a standard cowl.  I could measure from the 

starter ring to the back of the faceplate.  From the face of the starter 

ring plate to the back of the spinner plate I measure 2.95 inches.  I 

was able to mic from the face of the tooth to the back and 3.070 

inches.  Go to the site below to look at pics of where I took the 

measurements.  Hope this helps. 



Fred.

Jason,  

   

I will be doing the same install on my RV-10.  If you have not yet purchased the spinner, I just bought one from MustangAero at a much reduced price ($885 for the polished version, $785 for the unpolished one).  

   

The only recommendation I can offer is to not do any cowl work until you have at lease the spinner in hand.  There is a huge slug or work needed to get a proper cowl fit.  Without at least the spinners back plate mounted you run a risk of doing a lot of rework.
