This question is for all you prop experts... I just purchased a Hartzell HC-C2YL-1BF/F7663-4. I am hanging it on the o-320 e2a. I ordered prop flange bushings from ECI thru a company in redding CA. The bushings arrived the other day and after inspecting them and taking careful measurments I noticed that the bushings are too long for my application by approx. .11 in. I checked Lycomings service inst. 1098H and looks like I got the bushings for the .38 crank shaft flange and I have the .27 flange. I called ECI and they will take the bushings back but here is my delemma, ECI does not have the bushings I need but can order them. I paid 166.00 for all six bushings form ECI and Just one of the shorter (of which I need 2) .480 bushings is $330.00. EA. that comes to almost $900.00 for all six. So here is my question. Can I put a thin spacer behind the prop flange to add to the thickness of the crank flange/ring gear so the bushings protrude into the prop flange at the correct length? I use to have a counter weight prop that had gaskets in this location. I am not opposed to machining the bushings but that is at the very bottom of the list of options, even under purchasing the way more expensive bushings. Which by the way makes me want to volmit.
Any good advise will greatly help.
