My Ercoupe Service Manual (Univair PN 004-00001K) states on P40

"With strut extended, fill it up to red line on gage; it should take
about 1 1/2 pints of fluid.  In static position, fluid is at green
mark."

Don't know about Alon, but 7 to 11 inches corresponds somewhat to where
gage marks are in my description.

        Coupers:

        A few weeks ago I probably misinformed another inquirer
        regarding filling the nose strut.  The Alon Maintenance
        Manual says nothing about a gauge, only to "fill to its
        working limit" 'it will take approximately 1 1/2 pints.' 
        {My filler plug showed no signs of a gauge.)  


        After reading your e-mail advice I went back to the hangar
        and read every piece of service advice I had.  The only
        reference I could find was in "Fornaire S/B 113" which also
        said to 'fill to its working limit' plus in a note said '7
        to 11 inches below the top surface of the filler plug
        hole.'  I assume that this is with the strut extended. 
        Having seen the inside of the strut, I now understand that
        this would assure that at its lowest level, fluid would
        cover the piston valving.  I guess I'll include the level
        check at my next annual by inserting a small diameter dowel
        down there to check fluid level.
